    Resumen
    Although Alternaria spores are well-known allergenic fungal spores, automatic bioaerosol recognition systems have not been trained to recognize these particles until now. Here we report the development of a new algorithm able to classify Alternaria spores with BAA500 automatic bioaerosol monitors. The best validation score was obtained when the model was trained on both data from the original dataset and artificially generated images, with a validation unweighted mean Intersection over Union (IoU), also called Jaccard Index, of 0.95. Data augmentation techniques were applied to the training set. While some particles were not recognized (false negatives), false positives were few. The results correlated well with manual counts (mean of four Hirst-type traps), with R2 = 0.78. Counts from BAA500 were 1.92 times lower than with Hirst-type traps. The algorithm was then used to re-analyze the historical automatic pollen monitoring network (ePIN) dataset (2018-2022), which lacked Alternaria spore counts. Re-analysis of past data showed that Alternaria spore exposure in Bavaria was very variable, with the highest counts in the North (Marktheidenfeld, 154 m a.s.l.), and the lowest values close to the mountains in the South (Garmisch-Partenkirchen, 735 m a.s.l.). This approach shows that in our network future algorithms can be run on past datasets. Over time, the use of different algorithms could lead to misinterpretations as stemming from climate change or other phenological causes. Our approach enables consistent, homogeneous treatment of long-term series, thus preventing variability in particle counts owing to changes in the algorithms.

    Resumen
    Tree phenology is sensitive to climate warming and changes in seasonal precipitation. Long xylogenesis records are scarce, thus limiting our ability to analyse how radial growth responds to climate variability. Alternatively, process-based growth models can be used to simulate intra-annual growth dynamics and to better understand why growth bimodality varies along temperature and precipitation gradients. We used the Vaganov-Shashkin (VS) growth model to analyse the main climatic drivers of growth bimodality in eight trees and shrubs conifers (four pines and four junipers) across Spain. We selected eleven sites with different continentality degree and spring/autumn precipitation ratios since we expected to find pronounced bimodal growth in less continental sites with spring and autumn precipitation peaks. The VS model successfully simulated annual growth rates at all sites as a function of daily temperature and soil moisture data. Bimodal growth patterns clustered into less continental sites showing low spring/autumn precipitation ratios. This finding agrees with observed climate-growth associations showing that growth was enhanced by wet-cool winter-to-spring conditions, but also by wet autumn conditions in the most bimodal sites. We observed a stronger growth bimodality in pines compared to junipers.

    Resumen
    We reported the first record of the rare species Trocheta subviridis Dutrochet, 1817 (Arhynchobdellida, Erpobdellidae) from north-eastern Spain (Suspiro stream at Señorio de Bértiz Natural Park, Navarra, Spain). The species was previously recorded in Spain by Cordero del Campillo (1980) and García Más and Jiménez (1981). However, the latter authors admitted (Garcia Más & Jiménez, 1984) that both citations could be considered erroneous due to a misinterpretation by Cordero del Campillo of Blanchard (1893) (Jueg, 2008). Thus, considering the limited and uncertain information about T. subviridis in Spain, we can argue that our specimen is the first valid record reported for the species in the Iberian Peninsula.

    Resumen
    As the number of introduced species keeps increasing unabatedly, identifying and prioritising current and potential Invasive Alien Species (IAS) has become essential to manage them. Horizon Scanning (HS), defined as an exploration of potential threats, is considered a fundamental component of IAS management. By combining scientific knowledge on taxa with expert opinion, we identified the most relevant aquatic IAS in the Iberian Peninsula, i.e., those with the greatest geographic extent (or probability of introduction), severe ecological, economic and human health impacts, greatest difficulty and acceptability of management. We highlighted the 126 most relevant IAS already present in Iberian inland waters (i.e., Concern list) and 89 with a high probability of being introduced in the near future (i.e., Alert list), of which 24 and 10 IAS, respectively, were considered as a management priority after receiving the highest scores in the expert assessment (i.e., top-ranked IAS). In both lists, aquatic IAS belonging to the four thematic groups (plants, freshwater invertebrates, estuarine invertebrates, and vertebrates) were identified as having been introduced through various pathways from different regions of the world and classified according to their main functional feeding groups. Also, the latest update of the list of IAS of Union concern pursuant to Regulation (EU) No 1143/2014 includes only 12 top-ranked IAS identified for the Iberian Peninsula, while the national lists incorporate the vast majority of them. This fact underlines the great importance of taxa prioritisation exercises at biogeographical scales as a step prior to risk analyses and their inclusion in national lists. This HS provides a robust assessment and a cost-effective strategy for decision-makers and stakeholders to prioritise the use of limited resources for IAS prevention and management. Although applied at a transnational level in a European biodiversity hotspot, this approach is designed for potential application at any geographical or administrative scale, including the continental one.

    Resumen
    IUCN Red List assessments for fish species can quickly become out of date. In recent years molecular techniques have added new ways of obtaining information about species distribution or populations. In this work, we propose the Iberian Peninsula as an example of reassessment needs in its endangered freshwater fish fauna. We compiled the list of freshwater fish species occurring in continental Spain and Portugal and examined their conservation status in global and national Red Lists. We retrieved records for these species in the Iberian Peninsula and calculated several biological indexes (richness and vulnerability indexes). Our results showed a patchy data coverage of fish records in the Iberian Peninsula. Threat levels reported within national Red Lists are higher than their global counterparts, reinforcing the necessity of improving and maintaining up to date national Red Lists. Iberian watersheds have moderate levels of threat and high levels of out of date assessments. The nearly fully completed genetic databases for Iberian fish species, along with the limited distribution of many endangered species and the necessity of update their assessments constitute an excellent opportunity to use data obtained from eDNA to improve species monitoring practices and their conservation status.

    Resumen
    The issue of air pollutants from livestock buildings is prevalent in the literature. Because they and their emissions impact both animal production and livestock building users as well as the outdoor environment. This paper aims to compile and review data available in the scientific literature on the types of pollutants for a better understanding of their generation form, their distribution according to the kind of animal, and the main factors affecting their generation and concentration, i.e., the rearing system, the indoor microclimate, and the manure management. The elevated generation of pollutants in animal buildings is tied to the dense occupancy in this industrial activity. The indoor air quality is defined according to the type of livestock in animal housing, considering its welfare needs, and the types and concentrations of pollutants generated as a function of the family of animal and the management used in production. The main gases generated are CH4, CO2, H2S, NH3, N2O, in addition to particulate matter and airborne microorganisms such as fungi and bacteria that very negatively affect the health of animals and users of the animal buildings.

    Resumen
    The efficient conservation of vulnerable ecosystems in the face of global change requires a complete understanding of how plant communities respond to various environmental factors. We aim to demonstrate that a combined use of different approaches, traits, and indices representing each of the taxonomic and functional characteristics of plant communities will give complementary information on the factors driving vegetation assembly patterns. We analyzed variation across an environmental gradient in taxonomic and functional composition, richness, and diversity of the herb-layer of a temperate beech-oak forest that was located in northern Spain. We measured species cover and four functional traits: leaf dry matter content (LDMC), specific leaf area (SLA), leaf size, and plant height. We found that light is the most limiting resource influencing herb-layer vegetation. Taxonomic changes in richness are followed by equivalent functional changes in the diversity of leaf size but by opposite responses in the richness of SLA. Each functional index is related to different environmental factors even within a single trait (particularly for LDMC and leaf size). To conclude, each characteristic of a plant community is influenced by different and even contrasting factors or processes. Combining different approaches, traits, and indices simultaneously will help us understand how plant communities work.

    Resumen
    The monitoring of biological indicators is required to assess the impacts of environmental policies, compare ecosystems and guide management and conservation actions. However, the growing availability of ecological data has not been accompanied by concomitant processing tools able to facilitate data handling and analysis. Multiple common challenges limit the usefulness of biomonitoring information across ecosystems and biological groups. Biomonitoring data analysis is currently constrained by time-consuming steps for data preparation and a data processing environment with limited integration in terms of software, biological groups, and protocols. We introduce biomonitoR, a package for the R programming language that addresses technical challenges for the management of ecological data and metrics calculation. biomonitoR implements most of the biological indices currently used or proposed in different fields of ecology and water resource management. Its combination of customizable functions aims to support a transferable and comprehensive biomonitoring workflow in a user-friendly environment.

    Resumen
    Biodiversity loss is a global problem, accelerated by human-induced pressures. In the marine realm, one of the major threats to species conservation, together with climate change, is overfishing. In this context, having information on the conservation status of target commercial marine fish species becomes crucial for assuring safe standards. We put together fisheries statistics from the FAO, the IUCN Red List, FishBase, and RAM Legacy databases to understand to what extent top commercial species¿ conservation status has been assessed. Levels of assessment for top-fished species were higher than those for general commercial or highly commercial species, but almost half of the species have outdated assessments. We found no relation between IUCN Red List traits and FishBase Vulnerability Index, depreciating the latter value as a guidance for extinction threat. The RAM database suggests good management of more-threatened species in recent decades, but more data are required to assess whether the trend has reverted in recent years. Outdated IUCN Red List assessments can benefit from reputed stock assessments for new reassessments. The future of IUCN Red List evaluations for commercial fish species relies on integrating new parameters from fisheries sources and improved collaboration with fisheries stakeholders and managers.

    Resumen
    The freshwater pearl mussel Margaritifera margaritifera has been suffering major population declines in Europe. This endangered species is a host specialist and exclusively requires salmonid species (Salmo trutta and Salmo salar) to complete its life cycle. In theory, obligatory biotic interactions should deserve special conservation attention, because the loss or massive decline of fish hosts may elicit the extirpation of their affiliated species. While many threats disturbing M. margaritifera are similarly affecting salmonids, climate change is particularly alarming, with the potential to significantly change the fish-mussel dynamics. To evaluate the importance of including the occurrence of fish hosts for predicting the distribution of M. margaritifera in Europe, three datasets were used to build species distribution models (SDMs) with a maximum entropy (MaxEnt) approach: (1) environmental variables (ENV); (2) probability of fish hosts occurrence (FH); and (3) environmental variables and probability of fish hosts occurrence (ENV + FH). We identified the environmental variables that better explain M. margaritifera distribution and modelled its current and future distribution under a suite of climate change scenarios. Furthermore, projections were used to evaluate the adequacy of current networks of European protected areas in covering the suitable habitats for M. margaritifera.

    Resumen
    Pollen allergies have become one of the most wide-spread afflictions that impact quality of life. This has made automatic pollen detection, classification and monitoring a very important topic of research. This paper introduces a new public annotated image data-set of pollen with almost 45 thousand samples obtained from an automatic instrument. In this work we apply some of the best performing convolutional neural networks architectures on the task of pollen classification as well as some fully convolutional networks optimized for image segmentation on complex microscope images. We obtain an F1 scores of 0.95 on the new data-set when the best trained model is used as a fully convolutional classifier and a class mean Intersection over Union (IoU) of 0.88 when used as an object detector.

    La fauna hipogea o cavernícola ibero-balear ha sido a lo largo de muchos años puesta en evidencia por numerosos zoólogos en las distintas disciplinas. Especialistas de los distintos grupos faunísticos capaces de colonizar las cuevas y las aguas subterráneas que las recorren. Hoy sabemos que esta diversidad de troglobios y estigobios alcanza un total de 1364 taxones: 1285 especies y 79 subespecies hipogeas (cavernícolas) pertenecientes a cuatro filos: Plathyhelminthes (2), Annelida (23), Mollusca (122) y Arthropoda (1217) en todo el territorio ibero-balear. Una fauna que cuenta con numerosos ejemplos de elementos relictos de especial interés paleogeográfico. De la totalidad de taxones hipogeos o cavernícolas del territorio ibero balear, 438 taxones (430 especies y 8 subespecies) son estigobios y 926 taxones (852 especies y 74 subespecies) son troglobios. En lo referente a la distribución de los taxones troglobios es el distrito Cantábrico el que posee una mayor riqueza en especies y subespecies, un total de 208, seguido del Vasco con 163 taxones, el Pirenaico con 153 y el Bético con 142. Algo menos diversos son los distritos Levantino (124 taxones) y Catalán (104 taxones), seguidos de lejos por el Lusitánico con 46 taxones, el Balear con 41 y el Central con tan sólo 19. Entre los estigobios 156 especies y subespecies pueblan las aguas subterráneas de las regiones delimitadas por las cuecas lusitánicas.

    Resumen
    An intensive sampling in a colluvial mesovoid shallow substratum (MSS) of the Sierra de Guadarrama National Park, using 33 subterranean sampling devices (SSDs) is the origin of the Collembola studied in this paper. The data were obtained from the second extraction of the traps, in operation between October of 2015 and May of 2016. This paper presents the faunistic and diversity data along with the entire park (mostly at sampling points above 200 m a.s.l.) for this period, compares the data between the first extraction of the traps and the second one, and describes one species of the genus Pseudosinella that appears as new in the second campaign.

    Resumen
    The lack of knowledge about freshwater biodiversity in remote areas like montane Andean rivers is noticeable and hinder the development of efficient conservation plans for aquatic ecosystems. Habitat requirements of tropical Andean fishes have been poorly analysed, despite the relevance of these ecological features on the fish conservation strategies. The present study aimed to examine fish assemblages along the altitudinal gradient in tropical Andean rivers and their relationship to habitat features to detect the most relevant abiotic factors and their implication on conservation. This study was conducted on a regional scale, along six basins located in tropical Andes (500 to 2,692 m a.s.l.). We studied fish diversity and distribution and their habitats along these elevation gradients. We found 6,320 specimens from 53 genera. Our analysis for the six most common and widely distributed genera (Astroblepus, Brycon, Bryconamericus, Chaetostoma, Pimelodella and Trichomycterus) underlines the relevance of hydromorphological variables on fish community structure in the Andean montane rivers, whereas human alterations seem to be less significant. These findings could be useful for current management and conservation strategies considering present threats over tropical montane rivers.

    Resumen
    Carotenoid staining has been repeatedly shown to serve as a sexually selected individual quality signal. In different species, individuals that show brighter carotenoid-based signals have been found to have superior feeding abilities, recover faster from disease, and generally enjoy better body condition. In the common crossbill (Loxia curvirostra), the colour has also been related to the different populations, with northern and central European populations being described as redder than those in the Mediterranean region. A study in the Pyrenees showed that long-winged individuals had lower apparent survival, and the proportion of red individuals was higher in long-winged birds, concluding that they could be nomadic birds (that travel long distances). A priori, if the red crossbills are more mobile than the yellow and orange ones, their apparent survival will be lower. However, in our study, red males showed a greater survival than males of other colours and almost double than that of the yellow ones. These results suggest that red coloration is linked to higher quality individuals regardless of their mobility.

    Resumen
    In birds, early experiences determine the later behavioural phenotype of individuals and their way of adapting to the challenges they encounter in their environment. We investigated how the degree of exposure of barn owl chicks to humans and their biological parents influenced their behavioural response to humans and different environments. Only the treatment groups raised by human beings, or those that remained for less time with their biological parents (15 days posthatching), learned to fly towards their trainer. However, the two groups of chicks that were raised the longest by their biological parents (20 and 25 days) never flew towards their trainer. In these last groups, the filial imprint was shown not to be able to be reversed. Neophobia was estimated to emerge between 17 and 19 days of age, as barn owls were able to recognize the environment in which they were habituated, showing fear of a new environment. Birds were able to recognize the person who raised them and objects with which they had been raised. The results obtained in this work can help to establish breeding protocols in this and other species of birds of prey, which improve their adaptability to the environment where they will live, whether in captivity or in the wild.

    La amazonia peruana, conocida por ser hábitat de un gran número de especies, ha sido objeto de innumerables investigaciones con la finalidad de comprender mejor su biodiversidad. Uno de los grupos más estudiados en esta parte del Perú es el de los lepidópteros. Sin embargo, a pesar de que hay algunos trabajos en zonas como Loreto, Tingo María e incluso el mismo San Martín, aún quedan muchas partes de la selva por explorar y evaluar. En ese sentido, se considera muy importante la realización de investigaciones como la presente, que tuvo como objetivo determinar las especies de lepidópteros diurnos que habitan el bosque El Pelejo, San Martín, Perú. Los muestreos se llevaron a cabo en un área conservada ubicada dentro de la propiedad de Agroganadera Huallaga S. A. C. Se registraron 31 especies de lepidópteros correspondientes a cinco familias, siendo Nymphalidae la que presentó mayor riqueza de especies. Asimismo, todas las especies registradas en la presente investigación se encuentran en la categoría de Preocupación Menor de acuerdo con la lista roja de especies de la IUCN. Este estudio representa el primer listado de lepidópteros para el Bosque El Pelejo, siendo la base para futuras investigaciones sobre mariposas diurnas en este importante bosque de la Amazonia peruana.

    Resumen
    Alternaria conidia have high allergenic potential and they can trigger important respiratory diseases. Due to that and to their extensive detection period, airborne Alternaria spores are considered as a relevant airborne allergenic particle. Several studies have been developed in order to predict the human exposure to this aeroallergen and to prevent their negative effects on sensitive population. These studies revealed that some sampling locations usually have just one single Alternaria spore season while other locations generally have two seasons within the same year. However, the reasons of these two different seasonal patterns remain unclear. To understand them better, the present study was carried out in order to determine if there are any weather conditions that influence these different behaviours at different sampling locations. With this purpose, the airborne Alternaria spore concentrations of 18 sampling locations in a wide range of latitudinal, altitudinal and climate ranges of Spain were studied. The aerobiological samples were obtained by means of Hirst-Type volumetric pollen traps, and the seasonality of the airborne Alternaria spores were analysed. The optimal weather conditions for spore production were studied, and the main weather factor affectthat the temperature was the most relevant variable for the Alternaria spore dispersion and it influenced both the summer when the temperatures are extremely warm, what splits the favourable period for Alternaria spore production and dispersion into two separate ones, detected as two Alternaria spore seasons within the same year.

    Resumen
    The Australian Orchesellidae includes only 11 nominal species in four genera: Australotomurus Stach, 1947, Alloscopus Borner, 1906, Heteromurus Wankel, 1860, and Falcomurus Mandal, 2018. Here we describe Dicranocentrus dolosus sp. nov. from Cocos and Keeling Islands, the first species of the genus to be recorded from Australia. The new species is similar to D. inermodentes (Uchida, 1944) and D. indicus Bonet, 1930, but differs from both by the combination of the ventral head, mesothoracic and dental chaetotaxy. We also revisit Australotomurus based on previous studies to better interpret the dorsal macrochaetotaxy of the genus, and provide a synthetic map of chaetae to guide future studies on scaleless Orchesellidae. Finally, we present updated diagnoses to all genera and species of Australian Orchesellidae, as well as an identification key to all species.

    Resumen
    Background Climate and land-use changes, which include the application of various types of organic and inorganic fertilisers, have been reducing the species diversity of Mediterranean grasslands and threatening its conservation. Annual plants are one of the most diverse functional groups of species in these grasslands, despite suffering competitive pressure from perennial herbaceous and woody species, and they are essential for ecosystem functioning and stability. Aims To quantify how fertilisation modulates the impact of plant-to-plant interactions and climate fluctuations on the dynamics of annuals in Mediterranean grasslands. We hypothesised that the application of sewage sludge would increase competition between functional groups, reducing the abundance of annuals in the long-term, but would buffer the negative impacts of drought on the year-to-year fluctuation of the diversity of annuals. Methods In a semi-natural species-rich Mediterranean grassland in northern Spain, we analysed the changes in the taxonomical and functional composition and diversity of annuals over 14 years in response to variations in the abundance of perennial herbaceous and woody species, climate fluctuations and fertilisation with sewage sludge. We quantified separately the patterns of year-to-year fluctuations and long-term trends. Results The frequency and diversity of annuals decreased with higher abundance of perennial herbaceous species, drought in June and cold winters. The addition of sewage

    Resumen
    Global biodiversitytargets require us to identify species at risk of extinction and quantify status and trends of biodiversity. The Red List Index (RLI) tracks trends in the conservation status of entire species groups over time by monitoring changes in categories assigned to species. Here, we calculate this index for the world's fishes in 2010, using a sampled approach to the RLI based on a randomly selected sample of 1,500 species, and also present RLI splits for freshwater and marine systems separately. We further compare specific traits of a worldwide fish list to our sample to assess its representativeness. Overall, 15.1% of species in the sample were estimated to be threatened with extinction, resulting in a sampled RLI of 0.914 for all species, 0.968 in marine and 0.862 in freshwater ecosystems. Our sample showed fishing as the principal threat for marine species, and pollution by agricultural and forestry effluents for freshwater fishes. The sampled list provides a robust representation for tracking trends in the conservation status of the world's fishes, including disaggregated sampled indices for marine and freshwater fish. Reassessment and backcasting of this index is urgent to check the achievement of the commitments proposed in global biodiversity targets.

    Resumen
    Understanding the mechanisms underlying community stability has become an urgent need to protect ecosystems from global change and resulting biodiversity loss. While community stability can be influenced by species richness, synchrony in annual fluctuations of species, species stability and functional traits, the relative contributions of these drivers to stability are still unclear. In semi-natural grasslands, land-use changes such as fertilization might affect stability by decreasing richness and influencing year-to-year fluctuations. In addition, they can promote long-term directional trends, shifting community composition and influencing grassland maintenance. Thus, it is important to consider how species and community stability vary year-to-year but also in the long term. Using a 14-year vegetation time series of a species-rich semi-natural Mediterranean grassland, we studied the relative importance of richness, synchrony, species stability and functional traits on community stability. To assess land-use change effects on stability, we applied a fertilization treatment. To distinguish stability patterns produced by year-to-year fluctuations from those caused by long-term trends, we compared the results obtained using a detrending approach from those without detrending. Independently of the treatment and approach applied, the most stable communities were those composed of asynchronous species with low specific leaf area. Fertilization decreased year-to-year and long-term community stability by increasing community-weighted mean of specific leaf area, decreasing species stability or also reducing richness in the case of year-to-year stability. Additionally, traits such as seed mass had an indirect effect on stability through synchrony. Long-term trends appeared in control and fertilized plots (due to fertilization), decreasing community and species stability and leading to differences in the relationships found between community stability and some of its drivers. This reflects the importance of accounting for the effect of temporal trends on community and species stability using both a long-term and a year-to-year approach. Synthesis. Stability is influenced by richness, synchrony and functional traits. Fertilization decreases species and community stability by promoting long-term trends in species composition, favouring competitive species and decreasing richness. Studying stability at the community level and species level, and accounting for the effect of trends is essential to understand stability and its drivers more comprehensively.

    Resumen
    Along with some studies on soil fauna in various Sicilian sites, both agricultural lands and typical Mediterranean habitats, particular attention was paid to the Collembolan. Specific identification allowed to assess the occurrence in Sicily of 39 species not previously recorded, belonging to 10 families: Hypogastruridae (six species), Brachystomellidae (one species), Neanuridae (five species), Onychiuridae (three species), Tullbergiidae (seven species), Isotomidae (nine species), Entomobryidae (three species), Cyphoderidae (one species), Dicyrtomidae (one species), and Katiannidae (one species). Of these 39 species, 21 are new also for Italy. Furthermore, this is the first record of the genus Doutnatcia Rusek, 1974 for the fauna of Italy. The discovery of such a number of new species for Sicily (i.e. 35% of those known) and Italy by sampling a limited number of habitats, shows that the knowledge relating to this group of arthropods in Sicily is still very scarce.

    Resumen
    Natural history collections (NHCs) represent an enormous and largely untapped wealth of information on the Earth's biota, made available through GBIF as digital preserved specimen records. Precise knowledge of where the specimens were collected is paramount to rigorous ecological studies, especially in the field of species distribution modelling. Here, we present a first comprehensive analysis of georeferencing quality for all preserved specimen records served by GBIF, and illustrate the impact that coordinate uncertainty may have on predicted potential distributions. We used all GBIF preserved specimen records to analyse the availability of coordinates and associated spatial uncertainty across geography, spatial resolution, taxonomy, publishing institutions and collection time. We used three plant species across their native ranges in different parts of the world to show the impact of uncertainty on predicted potential distributions. We found that 38% of the 180+ million records provide coordinates only and 18% coordinates and uncertainty. Georeferencing quality is determined more by country of collection and publishing than by taxonomic group. Distinct georeferencing practices are more determinant than implicit characteristics and georeferencing difficulty of specimens. Availability and quality of records contrasts across world regions. Uncertainty values are not normally distributed but peak at very distinct values, which can be traced back to specific regions of the world. Uncertainty leads to a wide spectrum of range sizes when modelling species distributions, potentially affecting conclusions in biogeographical and climate change studies. In summary, the digitised fraction of the world's NHCs are far from optimal in terms of georeferencing and quality mainly depends on where the collections are hosted. A collective effort between communities around NHC institutions, ecological research and data infrastructure is needed to bring the data on a par with its importance and relevance for ecological research.

    Resumen
    Analysing temporal patterns in plant communities is extremely important to quantify the extent and the consequences of ecological changes, especially considering the current biodiversity crisis. Long-term data collected through the regular sampling of permanent plots represent the most accurate resource to study ecological succession, analyse the stability of a community over time and understand the mechanisms driving vegetation change. We hereby present the LOng-Term Vegetation Sampling (LOTVS) initiative, a global collection of vegetation time-series derived from the regular monitoring of plant species in permanent plots. With 79 data sets from five continents and 7,789 vegetation time-series monitored for at least 6 years and mostly on an annual basis, LOTVS possibly represents the largest collection of temporally fine-grained vegetation time-series derived from permanent plots and made accessible to the research community. As such, it has an outstanding potential to support innovative research in the fields of vegetation science, plant ecology and temporal ecology.

    Resumen
    Climate change is rearranging the mosaic of biodiversity worldwide. These broad-scale species re-distributions affect the structure and composition of communities with a ripple effect on multiple biodiversity facets. Using European Odonata, we asked: i) how climate change will redefine taxonomic, phylogenetic, and functional diversity at European scales; ii) which traits will mediate species¿ response to global change; iii) whether this response will be phylogenetically conserved. Using stacked species distribution models, we forecast widespread latitudinal and altitudinal rearrangements in Odonata community composition determining broad turnovers in traits and evolutionary lineages. According to our phylogenetic regression models, only body size and flight period can be partly correlated with observed range shifts. In considering all primary facets of biodiversity, our results support the design of inclusive conservation strategies able to account for the diversity of species, the ecosystem services they provide, and the phylogenetic heritage they carry in a target ecosystem.

    Resumen
    The introduction of invasive alien species (IAS) is a severe problem in ecosystems worldwide, heavily impacting biodiversity and especially endemic species. This situation is especially worrying in the Iberian Peninsula, since Spain and Portugal¿s rivers and lakes host an outstanding richness of endemic freshwater species. Ignorance about IAS presence and distribution is a serious problem that hampers its management. Regarding invasive fish species, difficulties in sampling and studying the ichthyofauna of lentic and deep waters, where many IAS inhabit, comprise some of the reasons for this lack of knowledge. In this study, we sampled the fish community of ten impounded waters in Navarre (Ebro River Basin, Spain) using multi-mesh gillnets. Four sampling points were dams located in rivers, and the remaining points were ponds. One of these ponds had a direct connection with a water channel, and another was found in a flood plain, so it connects with a nearby river in floods. The remaining ponds did not have a direct connection to any major river. A total of 14 fish species were detected (9 of which were IAS (64.3%)), with 3383 specimens collected (56% IAS). Only one of the analyzed dams did not contain IAS. Numerically, the most abundant fish was the exotic bleak (Alburnus alburnus) (almost 44% of the captures), followed by the native Ebro nase (Parachondrostoma miegii) (23.4%).

    Resumen
    Natural history collections constitute an enormous wealth of information of Life on Earth. It is estimated that over 2 billion specimens are preserved at institutions worldwide, of which less than 10% are accessible via biodiversity data aggregators such as GBIF. Moreover, they are a very important resource for eco¿evolutionary research, which greatly depends on knowing the precise location where the specimens were collected in order to characterize the environment in which they lived. Yet, only about 55% of the accessible records are georeferenced and only 31% have coordinate uncertainty information, which is critical for conducting rigorous studies. The awareness of this gap of knowledge which hinders the enormous potential of such data in research led to the organization of a workshop which brought together key players in georeferencing of natural history collections. The discussion and outcomes of this workshop are here presented.

    Resumen
    Soyka (1946) described the European fairyfly species Anagrus bakkendorfi Soyka (Hymenoptera: Mymaridae) from a single female collected on the same day, 7.x.1931, together with several non-type specimens incorrectly labeled as paratypes (Chiappini Triapitsyn 1999), on a window at its type locality, the former St. Ignatius Jesuit College in Valkenburg, Limburg, the Netherlands. Soyka (1956) did not mention type specimens of any of his species of Anagrus Haliday. He described Anagrus avalae Soyka (Soyka 1956) based apparently on a specimen collected on Mt. Avala, Belgrade, Serbia, former Yugoslavia, along with several other nominal species (some also from Valkenburg) that were later synonymized with A. avalae and A. bakkendorfi by Chiappini (1989) and Chiappini Triapitsyn (1999). The only, minor, morphological difference between the two nominal species is the length of the ovipositor in females relative to the length of the protibia, being at least 2.6× in A. bakkendorfi and at most 2.3× in A. avalae (Triapitsyn 2015). Specimens identifiable as both species were captured by the second author in 2000 by a Malaise trap in Iratibizkar, Irati Forest (Selva de Irati), Navarra, Spain. Chiappini Triapitsyn (1999) discussed both nominal species but despite recognizing their apparent conspecificity, no formal synonymy was proposed. Triapitsyn Berezovskiy (2004) and Triapitsyn (2015) also did not propose synonymy because at that time genetic evidence for conspecificity was lacking. ...

    The material for this study was obtained after intensive sampling in the colluvial mesovoid shallow substratum, or MSS, of the Sierra de Guadarrama National Park using 33 subterranean sampling devices (SSD). The data were obtained from the first extraction of the traps between May and October of 2015. This paper presents the results for the Entomobryomorpha Borner, 1913, which was part of the Collembola captured. Four Families and 12 genera have been studied: Isotomidae Schaffer, 1896 (Folsomia Willem, 1902, Tetracanthella Schott, 1891, Uzelia Absolon, 1901, Folsomides Stach, 1922, Isotomurus Borner, 1903, Parisotoma Bagnall, 1940, Pseueksoloma Handschin, 1924 and Pachyotoma Bagnall, 1949), Orchesellidae Borner, 1906 (Orchesella Templeton, 1835 and Heteromurus Wankel, 1860), Entomobryidae Schaffer, 1896 (Entomobrya Rondani, 1861) and Lepidocyrtidae Wahlgren, 1906 (Lepidocyrtus Bourlet, 1839 and Pseudosinella Schaffer, 1897). The species of Orchesella were studied in a previous paper (Baquero et al. 2017). The richness of the habitat sampled is defined by twenty-one species, eight of which are new: Pachyotoma penalarensis Baquero & Jordana n. sp., Entomobrya guadarramensis Jordana & Baquero n. sp., Entomobrya ledesmai Jordana & Baquero n. sp., Leptdocyrtus labyrinthi Baquero & Jordana n. sp., Lepidocyrtus paralignorum Baquero & Jordana n. sp., Lepidocyrtus purgatori Baquero & Jordana n. sp., Pseudosinella valverdei Baquero & Jordana n. sp. and Pseudosinella gonzaloi Baquero & Jordana n. sp. Entomobrya intermedia Brook, 1884 (England) is discussed and a new name Entomobrya katzi Jordana & Baquero n. sp. is proposed for F,. intermedia sensu Katz et al. (2015) based on the American specimens.

    Resumen
    Hay pocos estudios ecológicos sobre los patrones de diversidad de los macroinvertebrados acuáticos en la Amazonía peruana, a pesar de ser esenciales para la gestión y manejo de estos ecosistemas fluviales. En este contexto, el objetivo del presente estudio fue determinar su composición taxonómica y su relación con las variables ambientales a lo largo de un gradiente altitudinal del río Alto Madre de Dios, cuenca en donde podrían registrarse nuevas especies. Se establecieron 22 estaciones en un rango altitudinal de 398 a 2.411 m s.n.m., cuantificando las características fisicoquímicas del agua y del hábitat fluvial: pH, temperatura del agua (T, °C), conductividad eléctrica (CE, ¿S.cm-1), ancho del río (A, m), profundidad (P, cm), sombra y velocidad del flujo de la corriente (m·s-1). Para los muestreos de macroinvertebrados se utilizó una red ¿de patada¿ de 200 ¿m de tamaño de malla. Se identificaron 56 taxones distribuidos en los órdenes Acari, Ephemeroptera, Coleoptera, Diptera, Hemiptera, Megaloptera, Odonata, Plecoptera, Trichoptera y Decapoda. Los análisis multivariados de clasificación y agrupamiento permitieron establecer cuatro grupos de estaciones estadísticamente diferenciadas (p<0,05), principalmente por la velocidad y el tipo de sustrato dominante, lo que explica la abundancia y amplia distribución de Chironomidae, Baetodes, Thraulodes y Anacroneuria.

    Resumen
    Our study analyzes the distribution of fish communities related to the environmental variables of the Alto Madre de Dios River, an Andean-Amazon watershed of southern Peru, between 300 and 2811 m a.s.l. within the Manu Biosphere Reserve. We provide new ecological and diversity data on fishes for these poorly studied rivers and new data for palm swamp habitats. With electric fishing techniques, we collected a total of 1934 fish specimens belonging to 78 species, 42 genera and 15 families. To assess main patterns of diversity we combined SIMPER and ANOSIM with canonical correspondence analysis to obtain an overview of the community structure of fish and their distribution related to aquatic habitats. Our results show an important shift on fish diversity at 700 m a.s.l. separating headwater and middle-lowland communities. Electrofishing was a hindrance due to the depth, flow and low conductivity of the rivers, but also allowed us to capture fish not observed with other techniques. We also compared the use of elevation with slope as an alternative variable for statistical analysis. Our results show that slope offers a solid and equivalent explanation for fish distribution variability, avoids redundance, and instead of giving geographical data offers ecologically solid information.

    Resumen
    Rivers are very vulnerable to fragmentation caused by the presence of man-made barriers. To restore river basin connectivity, numerous indices have been developed to calculate river fragmentation and optimise barrier mitigation actions. These methods usually calculate connectivity for whole river basins, but sometimes it is useful to analyse the connectivity for certain elements of interest. The main goal of this study was to develop a simple method to calculate the connectivity of specific riverine habitats or fish meta-populations. The framework of the Dendritic Connectivity Index (DCI) created by Cote et al. in 2009 was changed to develop the Population Connectivity Index (PCI). This index would depend on the number of populations, the total river length occupied by each population, the distance between populations, the dispersal capability of the fish species and the presence of barriers in the river. The outcome of the index is a percentage that measures the degree of connectivity in a meta-population. The PCI was tested in four Iberian fish species with different dispersal capabilities: Salmo trutta, Luciobarbus comizo, Anaecypris hispanica and Cobitis vettonica. The results show a natural connectivity between populations (without considering dams) of 7.95-47.48%. The most connected meta-population was L. comizo while the most naturally fragmented meta-population was A. hispanica. When large impassable dams were added to the index the results show a connectivity of 2.19-16.48%. Dams reduce connectivity between 5.37 and 30.99 points. Dams were ranked according to their impact in the fragmentation of each studied meta-population. This PCI allows to find out naturally isolated fish meta-populations and to assess the impact of dams in the fragmentation of fish meta-populations. It can also be used in dam prioritization decisions such as dam removals and new dam location selection. It also can aid in the creation of river ecological corridors between endangered or important fish populations.

    Resumen
    We studied Entomobryidae and Orchesellidae springtails collected throughout Chechnya, Ingushetia, and Dagestan, Russia. Three new species of the genus Entomobrya (E. multisetis sp. nov., E. hirsutothorax sp. nov., and E. kremenitsai sp. nov.), and one of Entomobryoides (E. dagestanicus sp. nov.) are described. Taxonomic information for Entomobrya nicoleti (Lubbock, 1868), Willowsia potapovi Zhang et al., 2011, and Heteromurus nitidus (Templeton, 1836) in Templeton & Westwood 1836 from the Caucasus are given. Although the Caucasus is faunistically interesting, the Collembola of this region are poorly studied. The list of the Caucasian species of the family Entomobryidae and, particularly, the genus Entomobrya, appears to be very limited. In the past, Stach (1963) described four new species and recorded three more based on color patterns. Afterward, several pattern-identified species were mentioned in the local lists of different areas of Caucasus (Rasulova 1980; Kremenitsa 2002; Dobrolubova 1982; and others, see Table 1). The only known modern taxonomic paper on the genus for the Caucasus was by Jordana et al. (2011a) where three new species were described from Russia (Kabardino-Balkaria) and Armenia. Concerning earlier described forms, in his monograph, Jordana (2012)

    Resumen
    Simple Summary The material for this study was obtained after intensive sampling in the colluvial mesovoid shallow substratum (MSS) of the Sierra de Guadarrama National Park using 33 subterranean sampling devices (SSD). The data were obtained from the first extraction of the traps between May and October of 2015. This paper presents the results for a small part of the total Collembola captured (4.4% of the total for this sampling), namely, the Neelipleona and Symphypleona. Eleven species belonging to seven families were identified, two of which are new species. Based on the results of this study, and others previously published on Collembola of the MSS in the Sierra de Guadarrama National Park, the presence of epigeal and edaphic species is observed, which, in general, are not as abundant as the newly discovered species. The high abundance and extensive presence in the hypogean environment of most of the new species discovered are indicative that the MSS has a unique and distinct Collembola community. Megalothorax minimus (Neelidae) and Sphaeridia pumilis (Sminthurididae) had already been identified in surface sampling from Sierra de Guadarrama. In Europe, Sminthurinus gisini (Katiannidae) seems to be associated with environments at specific altitudes, and has little representation in this sampling. Pygmarrhopalites custodum Baquero and Jordana sp. nov. (Arrhopalitidae) coexists with two previously identified surface occurring species of the same family (P. elegans and Arrhop

    Resumen
    Desde hace unos años la actividad de la espeleología ha visto enriquecidos sus objetivos con la consideración del estudio de la vida en las cuevas. En la actualidad hay muchos biólogos dedicados al estudio de las biocenosis en miles de cavidades a lo largo de todo el mundo, y se están revisando algunas en las que solo se habían recogido datos geológicos. También hay muchos espeleólogos tradicionales que ahora, durante sus expediciones, además de realizar mapas y recoger parámetros fisicoquímicos, recogen material que envían a taxónomos con los que colaboran. La fauna de las cuevas es muy interesante, pero a la vez delicada y escasa, por lo que la captura de ejemplares debe hacerse con el máximo cuidado y limitación en el número de ejemplares. Tanto la propia visita a una cueva con fauna, como la captura, recogida de información, o envío final al taxónomo deberían hacerse con el máximo rigor. En este trabajo se pretende recopilar de forma clara y resumida todas las cuestiones que permiten conseguir este objetivo. Se consideran las actitudes, metodologías (como captura directa o trampas), los materiales a utilizar, la etiquetación, y el modo de realizar los envíos para el intercambio de material. Aunque la mayoría de las cuestiones metodológicas no están referidas a un área geográfica concreta, la clave de géneros que se incluye está enfocada a la identificación de los presentes en la península ibérica.

    Resumen
    Zoos and aquaria, often regarded as preservation-cum-entertainment enterprises, are also actors in the effort to curb the biodiversity crisis: raising awareness, supporting conservation, and conducting research. We assessed trends in zoo and aquaria research topics and study organisms over time worldwide. For the zoos and aquaria registered in the Species360's Zoological Information Management System and the World Association of Zoos and Aquariums, we compiled metadata on their research published in the peer-reviewed literature indexed in Scopus and carried out a keyword frequency analysis. The production of scientific papers by zoos increased at a much faster rate than the average accrual of scientific papers in the literature. Evolution of research themes ran parallel to that of biological sciences (e.g., development of molecular genetics or increased awareness about conservation). The focus of 48.5% of zoo-led research was on vertebrates, of which mammal research was 33.7%. Whether zoos are effectively contributing to conservation may still be debatable, but our results highlight their institutional efforts to increase knowledge about the species in their care.

    Resumen
    The studied area (Far East of Russia) is very little investigated for the Entomobryidae family. A specific sampling in the area has made it possible to detect the presence of four and one new species of the genera Entomobrya and Willowsia respectively, which are herein described (E. amurica sp. nov., E. mediostriata sp. nov., E. umbroviolacea sp. nov., E bicincta sp. nov. and W babykinae sp. nov.) from the western part of the Far East of Russia. Homidia hjesanica is also recorded.

    Resumen
    The understory of temperate forests harbour most of the plant species diversity present in these ecosystems. The maintenance of this diversity is strongly dependent on canopy gap formation, a disturbance naturally happening in non-managed forests, which promotes spatiotemporal heterogeneity in understory conditions. This, in turn, favours regeneration dynamics, functioning and structural complexity by allowing changes in light, moisture and nutrient availability. Our aim is to study how gap dynamics influence the stability of understory plant communities over a decade, particularly in their structure and function. The study was carried out in 102 permanent plots (sampled in 2006 and revisited in 2016) distributed throughout a 132 ha basin located in a non-managed temperate beech-oak forest (Bertiz Natural Park, Spain). We related changes in the taxonomical and functional composition and diversity of the understory vegetation to changes in canopy coverage. We found that gap dynamics influenced the species composition and richness of the understory through changes in light availability and leaf litter cover. Species with different strategies related to shade tolerance and dispersion established in the understory following the temporal evolution of gaps. However, changes in understory species composition in response to canopy dynamics occur at a slow speed in old-growth temperate forests, needing more than a decade to really be significant.

    Resumen
    River connectivity is essential for the correct functioning of freshwater ecosystems at all scales. However, it has not received the necessary attention by researchers, managers and policymakers until recent years. In this review, we recap the state of knowledge in river connectivity and its applications to conservation. We describe the particular characteristics of river connectivity and summarise the effects of its interruption in different freshwater ecosystem elements. We then focus on the effects of the lack of segment connectivity in fish species and review the different methods developed to study it. The application of connectivity in freshwater fish conservation areas is also reviewed, which highlights the lack of studies on this subject. Finally, connectivity restoration is studied. The review addresses these topics in a general way and then focus on the Iberian Peninsula.The Iberian Peninsula is an interesting place to study river connectivity because it has one of the highest numbers of dams per square kilometre and a large number of endemic and endangered freshwater fish species. Despite the high number of fish species affected by water extraction and damming, river connectivity and its effect in Iberian freshwater fish populations have not been well studied. A small number of studies analyse the effect of small dams in nearby fish communities, but large-scale impact assessments are scarce.

    Resumen
    Telomere shortening with age has been documented in many organisms, but few studies have reported telomere length measurements in amphibians, and no information is available for growth after metamorphosis, nor in wild populations. We provide both cross-sectional and longitudinal evidence of net telomere attrition with age in a wild amphibian population of natterjack toads (Epidalea calamita). Based on age-estimation by skeletochronology and qPCR telomere length measurements in the framework of an individual-based monitoring programme, we confirmed telomere attrition in recaptured males. Our results support that toads experience telomere attrition throughout their ontogeny, and that most attrition occurs during the first 1-2 years. We did not find associations between telomere length and inbreeding or body condition. Our results on telomere length dynamics under natural conditions confirm telomere shortening with age in amphibians and provide quantification of wide telomere length variation within and among age-classes in a wild breeding population.

    Resumen
    Different indices have been developed to quantify the extent and severity of river fragmentation. These indices vary depending on the specific goals of the study. Here, we present a new Conservation Connectivity Index (CCIp) for potamodromous fish species that considers the conservation value (richness, rarity and vulnerability) of river segments. The Iberian Peninsula holds > 20 endemic and endangered potamodromous fish species as well as > 1000 large dams (> 1 hm3 of capacity). The CCIp was calculated for the eight most important river basins of the Iberian Peninsula and compared to the Dendritic Connectivity Index (DCIp) developed by Cote et al. in 2009, which uses only river length as a habitat variable. With the use of both DCIp and CCIp, the dams were analysed and ranked according to their impacts on the river basin. The main results show that Iberian river basins are heavily fragmented, with river basin connectivity percentages of less than 20% in most cases using both DCIp and CCIp. CCIp values are slightly higher than DCIP values in almost all cases. When the impact of individual dams is analysed, differences also appear between the DCIp and CCIp. CCIp highlights the impact of dams located in areas of high fish conservation value while DCIp emphasize the impact of dams fragmenting large river segments.

    Resumen
    The bleak Alburnus alburnus is native to most of Europe. This cyprinid fish is a successful invader in the Iberian Peninsula. No studies exist on its foraging strategies on a large scale for this ecoregion. The aim of the present study was to compare dietary traits of invasive bleak among the main Iberian rivers and a "reference" native bleak population from France. Bleak were sampled during May-June 2019 from the Iberian Rivers Ebro, Tagus, Guadiana, Segura and Guadalquivir and the River Saône (France). Diptera larvae and zooplankton were common food categories in the River Saône. Insect nymphs were more important in the River Ebro. The intake of plant material was higher in the River Tagus. Flying insects were more consumed in the River Guadiana. Nektonic insects were important in the River Guadalquivir. Detritus was a frequent food category for all populations, in terms of occurrence and mass. Dietary parameters followed a unimodal response in relation to the latitudinal gradient, with the maximum values for the Tagus and Guadiana populations. Overall, results suggest that this wide interpopulation variability will contribute to the species¿ successful establishment throughout Mediterranean Europe, which poses a serious risk to its highly valuable native fish fauna.

    Resumen
    Suspended moult is a relatively common phenomenon in birds, but it has remained relatively ignored for a long time in studies dealing with moulting process. Furthermore, the new and increasing number of models used to estimate moult duration systematically omit the fact that suspended moults can occur and that they significantly alter parameter estimates. Taking suspended moults into account is critical to obtain reliable moult-associated parameter estimates, which is fundamental given the demographic and evolutionary consequences of moult in birds. The main goal of this work is to develop a standardised method useful for characterising the main moulting parameters (such as the duration and starting date) of bird species that perform suspended moults. Additionally, with the aim of delving into our understanding of when and why suspended moults happen, we study their relationship with the occurrence of second breeding attempts in summer. We used data obtained from a Red Crossbill population in the Pyrenees during a period of 17 years. We observed that the percentage of crossbills undergoing suspended moult was approximately 50% during summer (July-August) and that moult suspension ultimately gives rise to a lengthened moulting period. Underhill-Zucchini models assume a time-linear replacement of feathers, overestimating the moult duration. Based on these same modelling approaches, we proposed a method to calculate the real moult duration after removing the time during which the moult was suspended. We also obtained evidence supporting the idea that crossbills suspend their moult as a strategy that could increase their breeding output in summer. The method proposed here can be used as a tool for working with species that undergo suspended moults.

    Resumen
    The stability of ecological communities is critical for the stable provisioning of ecosystem services, such as food and forage production, carbon sequestration, and soil fertility. Greater biodiversity is expected to enhance stability across years by decreasing synchrony among species, but the drivers of stability in nature remain poorly resolved. Our analysis of time series from 79 datasets across the world showed that stability was associated more strongly with the degree of synchrony among dominant species than with species richness. The relatively weak influence of species richness is consistent with theory predicting that the effect of richness on stability weakens when synchrony is higher than expected under random fluctuations, which was the case in most communities. Land management, nutrient addition, and climate change treatments had relatively weak and varying effects on stability, modifying how species richness, synchrony, and stability interact. Our results demonstrate the prevalence of biotic drivers on ecosystem stability, with the potential for environmental drivers to alter the intricate relationship among richness, synchrony, and stability.

    Resumen
    Questions: Compensatory dynamics are described as one of the main mechanisms that increase community stability, e.g., where decreases of some species on a year-to-year basis are offset by an increase in others. Deviations from perfect synchrony between species (asynchrony) have therefore been advocated as an important mechanism underlying biodiversity effects on stability. However, it is unclear to what extent existing measures of synchrony actually capture the signal of year-to-year species fluctuations in the presence of long-term directional trends in both species abundance and composition (species directional trends hereafter). Such directional trends may lead to a misinterpretation of indices commonly used to reflect year-to-year synchrony. Methods: An approach based on three-term local quadrat variance (T3) which assesses population variability in a three-year moving window, was used to overcome species directional trend effects. This "detrending" approach was applied to common indices of synchrony across a worldwide collection of 77 temporal plant community datasets comprising almost 7,800 individual plots sampled for at least six years. Plots included were either maintained under constant "control" conditions over time or were subjected to different management or disturbance treatments. Results: Accounting for directional trends increased the detection of year-to-year synchronous patterns in all synchrony indices considered.

    Resumen
    The material for this study was obtained after intensive sampling in the colluvial milieu souterrain superficiel (mesovoid shallow substratum, or MSS) of the Sierra de Guadarrama National Park using 33 subterranean sampling devices (SSD). The data were obtained from the first extraction of the traps between May and October of 2015. This paper presents the results for the Poduromorpha taxon, which was part of the total Collembola captured. Of the 17 species captured in this study, 11 had previously been cited in Guadarrama, four are new references, and two new species. Friesea ortunoi Jordana and Baquero sp. nov. is characterised as having seven eyes, tibiotarsus as having one clavate chaetae and only two spiniform chaetae on Abd VI. Schaefferia sendrai Jordana and Baquero sp. nov. is characterised as having six eyes, seven sensilla on Ant IV, a bi- or tri-lobed apical vesicle on the antennal tip, claws with internal tooth and lateral (posterior) tooth, dens with six chaetae and retinaculum with 5 + 4 teeth (asymmetrically). Based on the results of the study of the group of species of Xenylla Tullberg, 1869 that appeared, Xenylla xavieri Gama, 1959 is separated from Xenylla lotharingiae Thibaud, 1963 and a brief description of the latter is provided. The comparative study of the Schaefferia Absolon, 1900 species related to the new species found in the Sierra de Guadarrama National Park led to the description of two new species: Schaefferia fjellbergi Jordana and Baquero sp. nov. and Schaefferia babenkoi Jordana and Baquero sp. nov., accepting the previous descriptions. The mesovoid shallow substratum (MSS) was revealed as an important habitat for the richness of the Collembola species. Furthermore, the findings showed the value of MSS as an indicator of the richness of the Collembola species. As many as 3000-4000 specimens were gathered in one sample device SSD. Among all specimens, the most abundant was Hypogastrura meridionalis Steiner, 1955 (77.7 %) and the least abundant was Xenylla schillei Borner, 1903 (11.5 %). (C) 2020 Elsevier GmbH.

    Resumen
    The determinants of biodiversity patterns in the subterranean habitat called Mesovoid Shallow Substratum (MSS) are not well-understood. In this study, thirty-three scree slopes at high altitudes were selected across the Sierra de Guadarrama National Park in central Spain to investigate the effect of ten environmental variables on the abundance and species diversity of the spider and springtail assemblages from the colluvial MSS. In each locality, a multiperforated PVC tube with a pitfall trap inside was buried up to 1 m deep, and generalized linear models and Mantel tests were used to analyze the effect of mainly climate- and habitat-related variables on the diversity patterns of both taxa. A total of 1143 individual spiders belonging to 54 species and 40 811 springtail individuals belonging to 62 species were collected. The analyses indicated that cold temperatures and the presence of forest cover on the surface significantly enhance richness and abundance in the two taxa. Environmental similarity also had a small positive effect on faunistic similarity. However, the effects of temperature and habitat detected on spider richness and abundance were stronger than on springtails, whereas the reverse was found regarding faunistic similarity. These results indicate that subterranean dwellers respond differently to the same environmental factors, which in turn, points to a different degree of affinity for the MSS.

    Resumen
    Rapid adaptation to global change can counter vulnerability of species to population declines and extinction. Theoretically, under such circumstances both genetic variation and phenotypic plasticity can maintain population fitness, but empirical support for this is currently limited. Here, we aim to characterize the role of environmental and genetic diversity, and their prior evolutionary history (via haplogroup profiles) in shaping patterns of life history traits during biological invasion. Data were derived from both genetic and life history traits including a morphological analysis of 29 native and invasive populations of topmouth gudgeonPseudorasbora parvacoupled with climatic variables from each location. General additive models were constructed to explain distribution of somatic growth rate (SGR) data across native and invasive ranges, with model selection performed using Akaike's information criteria. Genetic and environmental drivers that structured the life history of populations in their native range were less influential in their invasive populations. For some vertebrates at least, fitness-related trait shifts do not seem to be dependent on the level of genetic diversity or haplogroup makeup of the initial introduced propagule, nor of the availability of local environmental conditions being similar to those experienced in their native range. As long as local conditions are not beyond the species physiological threshold, its local establishment and invasive potential are likely to be determined by local drivers, such as density-dependent effects linked to resource availability or to local biotic resistance.

    Resumen
    More than 33,500 fish species inhabit freshwater and marine environments, according to FishBase database records. The International Union for the Conservation of Nature (IUCN) has assessed the conservation status of approximately half of them, the lowest percentage in any vertebrate group. In order to identify what factors may underlie this assessment gap, several traits were examined related to distribution, life-history, taxonomy, conservation, and the economic relevance of species according to their assessment status. IUCN assessment patterns were explored and separate analyses were included for freshwater and marine species. The results showed that IUCN assessments were biased towards economically developed regions, species with early description dates and species covered by current IUCN specialist groups. Species living in remote areas or habitats were more likely to be unassessed. In particular, South America had low assessment levels. Other traits such as commercial importance did not influence the assessment status of fish species. We therefore encourage assessment in poorly assessed areas and taxonomic subgroups to prompt timely conservation action to prevent species extinctions.

    Resumen
    Our world is in the midst of unprecedented change-climate shifts and sustained, widespread habitat degradation have led to dramatic declines in biodiversity rivaling historical extinction events. At the same time, new approaches to publishing and integrating previously disconnected data resources promise to help provide the evidence needed for more efficient and effective conservation and management. Stakeholders have invested considerable resources to contribute to online databases of species occurrences. However, estimates suggest that only 10% of biocollections are available in digital form. The biocollections community must therefore continue to promote digitization efforts, which in part requires demonstrating compelling applications of the data. Our overarching goal is therefore to determine trends in use of mobilized species occurrence data since 2010, as online systems have grown and now provide over one billion records. To do this, we characterized 501 papers that use openly accessible biodiversity databases. Our standardized tagging protocol was based on key topics of interest, including: database(s) used, taxa addressed, general uses of data, other data types linked to species occurrence data, and data quality issues addressed.

    Ante los indicadores de insostenibilidad ambiental y social, se busca un enfoque educativo eficaz que contribuya a revertirla. A tal efecto, se propone una educación moral, que no se centre tanto en contenidos como en facilitar que cada estudiante aprenda a buscarlos, hacerlos propios y los traduzca en compromisos de conducta personal. La propuesta educativa se presenta ejemplificada en una asignatura concreta, que sirve de hilo expositivo y ejemplo de aplicación. Tras una breve introducción sobre los indicadores de insostenibilidad, se presenta la planificación, metodología y objetivo de la asignatura. A continuación, se reflexiona sobre dos de los obstáculos a los que se enfrenta la educación moral en la actualidad: la fragmentación del saber y la dificultad para que los aprendizajes teóricos se traduzcan en conductas. Por último, se exploran dos oportunidades para la educación moral que pueden facilitar ese vínculo: la búsqueda de las causas profundas de problemas ambientales y sociales actuales, y el empleo de la belleza.

    Resumen
    Contemporary environmental sensitivity has characterized for decades the emerging culture in the developed world. It is not yet mainstream in influencing behavior at a global level, as the growing environmental impact of consumerism testifies particularly to it. Present day environmental sensitivity seems somehow at odds with Christianism, charged for decades alongside Judaism with major responsibility in the environmental crisis. This paper explains and discusses on seven interlinked aspects of the environmental value amply recognized across environmentalism. In examining them, Christian environmentalism learns particularly some demands of the Christian vocation that may remain neglected and demand a moral conversion both of Christians and of no non-Christians and non-believers. In accepting this demand, the Christian discerns the life-giving presence of Christ in many traits of the environmental sensitivity and culture. This encounter offers grounds for a reciprocal understanding and enrichment of Christians and non-believers or non-Christians, towards the attainment of a wider and deeper respect of environmental and human shared values.

    Resumen
    The advent of online data aggregator infrastructures has facilitated the accumulation of Digital Accessible Knowledge (DAK) about biodiversity. Despite the vast amount of freely available data records, their usefulness for research depends on completeness of each body of data regarding their spatial, temporal and taxonomic coverage. In this paper, we assess the completeness of DAK about terrestrial mammals distributed across the Iberian Peninsula. We compiled a dataset with all records about mammals occurring in the Iberian Peninsula available in the Global Biodiversity Information Facility and in the national atlases from Portugal and Spain. After cleaning the dataset of errors as well as records lacking collection dates or not determined to species level, we assigned all occurrences to a 10-km grid. We assessed inventory completeness by calculating the ratio between observed and expected richness (based on the Chao2 richness index) in each grid cell and classified cells as well-sampled or under-sampled. We evaluated survey coverage of well-sampled cells along four environmental gradients and temporal coverage. Out of 796,283 retrieved records, quality issues led us to remove 616,141 records unfit for this use. The main reason for discarding records was missing collection dates. Only 25.95% cells contained enough records to robustly estimate completeness. The DAK about terrestrial mammals from the Iberian Peninsula was low, and spatially and temporally biased.

    Resumen
    During the check-rearing period, strategies of prey provisioning can have a decisive impact on several reproductive aspects. Adults can maximise their foraging effort by increasing the number of fish-prey brought to the nest per unit time and/or by catching more energetic prey, i.e. larger prey or prey with relatively higher caloric values. The Common Kingfisher (Alcedo atthis) is a fish-eating predator normally breeding in freshwater habitats. We collect data on fish-prey proportions found at nests (n=10) and determined the caloric content of such fish-prey (6 species overall) in rivers in northen Iberia. The proportion of each fish-prey species in the nest was not correlated with the proportion of lipids, proteins or carbihydrates, nor with its caloric content. Furthermore, the most energetic prey was nor the most coomonly consumed, illustrating the fact that the Common Kingfisher does not fish for the most energetic prey during the chick-rearing period.

    Resumen
    The signal crayfish Pacifastacus leniusculus Dana, 1852 is a successful invasive species in the Iberian Peninsula. This is of particular conservation concern, as fish fauna is highly endemic and also threatened within this ecoregion. The aim of this study was to analyze behavioral interactions and trophic overlap between signal crayfish and native fishes in Iberian rivers (northern Spain). Video cameras were used to record fish "dominance/evasion" after spatial encounters with crayfish. Diet composition and isotopic signatures (¿13C and ¿15N) were compared to evaluate the niche overlap. Fish were dominant in 25% of the encounters with juvenile crayfish, whereas this percentage was only 4% with adult crayfish. Observations showed a high fish "evasion" response for Pyrenean stone loach Barbatula quignardi (B¿cescu-Me¿ter, 1967) (>30%). Dietary results showed a high trophic overlap between signal crayfish with the pelagic Pyrenean minnow Phoxinus bigerri Kottelat, 2007 and the benthic loach. However, the isotopic niche overlap was low, with brown trout Salmo trutta L., 1758 showing the highest area (only 0.1 ¿2). Overall, our findings suggest that interferences may occur with native species for food (i.e., benthic invertebrates). Consequently, measures should be applied to control invasive crayfish in Iberian rivers.

    Resumen
    River fragmentation is one of the main threats to diadromous fish species. We aimed to create a new and simple connectivity index to calculate habitat accessibility that considers habitat suitability for fish species, using the Bidasoa River basin in the north of Spain and Atlantic salmon (Salmo salar) as an example. A habitat connectivity index (HCI) was calculated for the river basin using upstream passability and segment length as variables. We then calculated a new habitat quality index for each river segment and multiplied it by river segment length to create the Breeding Habitat Connectivity Index (HCIb). These 2 indices were first calculated using only upstream barrier passability and then by adding downstream passability. In each case, the indices show different outcomes but a similar pattern: in all cases, main-stem obstacles closest to the river mouth most affected the connectivity index, even when habitat quality was considered. Although we cannot compare the indices to the real area used by salmon because spatial tracking was not performed during the study years, we consider that including habitat quality in a river connectivity index adds useful information for scientists and managers.

    Resumen
    In business, the "long-tail economy" refers to a market strategy where the gravity center shifts from a few high-demand products to many, varied products focused on small niches. Commercialization of individually low-demand products can be profitable as long as their production cost is low and, all taken together, they aggregate into a big chunk of the market. Similarly, in the "business" of biodiversity data acquisition, we can find several mainstream products that produce zillions of bits of information every year and account for most of the budget allocated to increase our primary data-based knowledge about Earth's biological diversity. These products play a crucial role in biodiversity research. However, along with these large global projects, there is a constellation of small-scale institutions that work locally, but whose contribution to our understanding of natural processes should not be dismissed. These information datasets can be collectively referred to as the "long-tail biodiversity data".

Any policy aimed at protecting such ecosystems must first assess the threat factors and the potential harm, well before proposing conservation measures such as the creation and development of Protected Areas (PAs). These assessments must be done using a deep and sound knowledge of the actual and potential biodiversity variables. Freshwater ecosystems have been largely neglected in traditional PA design and management (Abell et al. 2007), be it for scarcity of biodiversity data, or for more perception-related reasons such as visibility and accessibility driving the allocation of conservation resources to more data-rich environments.

    Resumen
    With more than one billion primary biodiversity data records (PBR), the Global Biodiversity Information Facility (GBIF) is the largest and, arguably, most comprehensive and accurate resource about the biodiversity data on the planet. Yet, its gaps (taxonomical, geographical or chronological, among others) have often been brought to attention (Gaijy et al. 2013) and efforts are continuously made to ensure more uniform coverage. Especially as data obtained through this resource are increasingly being used for science, policy, and conservation (Ariño et al. 2018), drawing on every possible source of information to complement already existing data opens new opportunities for supplying the integrative knowledge required for global endeavors, such as understanding the global patterns of ecosystem and environment changes.

    Resumen
    This paper examines a single genus of springtails (Collembola, Entomobryidae, Entomobrya) across the Canary Islands archipelago. A great sampling effort carried out more than 20 years ago, and over several years, allows us to present the distribution of the genus with the presence of 17 species, some better represented by their abundance than others. In addition to some species present in continental Europe or elsewhere in the world, or those already reported for the Canary Islands (e.g., E. multifasciata (Tullberg, 1871), E. nigrocincta Denis, 1923, E. palmensis Jordana & Baquero, 2010, E. quinquelineata Börner, 1901 and E. unostrigata Stach, 1930), 12 new species have been detected and described, representing 71% of the total species found. All new species have been named in honour of important persons to the history of the Canary Islands, including some leaders. A combination of colouring patterns and other morphological characteristics that are easy to observe in most specimens (Katz et al. 2015a, b) have been used for the identification of the specimens, as is usual for the genus (Christiansen 1958), in addition to the dorsal macrochaetotaxy formula proposed by Jordana & Baquero (2005). Without this formula, many specimens could not have been identified or distinguished from already described species because the colourations ¿in many cases¿show ranges so broad as not to be diagnostic. In some species, the range of colouration can range from totally clear to totally dark,

    Resumen
    A primary aim of environmental education is to promote environmental values. Significant life experiences (SLE) are a powerful, fast and long-lasting way to achieve this objective, but they have received little scholarly attention thus far. As examples to help us characterize SLE and understand their function, the cases of three well-known environmentalists, Seton, Leopold, and Rodriguez de la Fuente, will be studied. All three environmentalists came into contact with wolves and looked them in the eye. These experiences, described as SLE, resulted in major changes in these environmentalists' lives. Although SLE are not reproducible on demand, by studying these cases through the narratives and biographies of these environmentalists, we can shed light on how to facilitate or promote, when possible, the acquisition of deep and lasting values through environmental education.

    Resumen
    Standards set up by Biodiversity Information Standards-Taxonomic Databases Working Group (TDWG), initially developed as a way to share taxonomical data, greatly facilitated the establishment of the Global Biodiversity Information Facility (GBIF) as the largest index to digitally-accessible primary biodiversity information records (PBR) held by many institutions around the world. The level of detail and coverage of the body of standards that later became the Darwin Core terms enabled increasingly precise retrieval of relevant records useful for increased digitally-accessible knowledge (DAK) which, in turn, may have helped to solve ecologically-relevant questions. After more than a decade of data accrual and release, an increasing number of papers and reports are citing GBIF either as a source of data or as a pointer to the original datasets. GBIF has curated a list of over 5,000 citations that were examined for contents, and to which tags were applied describing such contents as additional keywords. The list now provides a window on what users want to accomplish using such DAK. We performed a preliminary word frequency analysis of this literature, starting at titles, which refers to GBIF as a resource. Through a standardization and mapping of terms, we examined how the facility-enabled data seem to have been used by scientists and other practitioners through time: what concepts/issues are pervasive, which taxon groups are mostly addressed, ...

    Resumen
    Researchers are embracing the open access movement to facilitate unrestricted availability of scientific results. One sign of this willingness is the steady increase in data freely shared online, which has prompted a corresponding increase in the number of papers using such data. Publishing datasets is a time-consuming process that is often seen as a courtesy, rather than a necessary step in the research process. Making data accessible allows further research, provides basic information for decision-making and contributes to transparency in science. Nevertheless, the ease of access to heaps of data carries a perception of `free lunch for all¿, and the work of data publishers is largely going unnoticed. Acknowledging such a significant effort involving the creation, management and publication of a dataset remains a flimsy, not well established practice in the scientific community. In a meta-analysis of published literature, we have observed various dataset citation practices, but mostly (92%) consisting of merely citing the data repository rather than the data publisher. Failing to recognize the work of data publishers might lead to a decrease in the number of quality datasets shared online, compromising potential research that is dependent on the availability of such data. We make an urgent appeal to raise awareness about this issue.

    Resumen
    Aim: To test the role of mountains as barriers to gene flow in co-distributed taxa with different life history traits. Location: Sierra de Guadarrama, Central Spain. Methods: We used larval genotypes of four amphibian species (Epidalea calamita, Hyla molleri, Pelophylax perezi and Pelobates cultripes) sampled on northern and southern slopes of Sierra de Guadarrama to describe genetic structure with F-ST, migration rates per generation, clustering algorithms and resistance by elevation surfaces. We also recorded individual displacement events as a proxy of dispersal potential during a seven-year monitoring project based on capture-mark-recapture (CMR). Results: All species travelled longer cumulative distances than those reported in the study area for P. cultripes (0.71 km). Individuals of E. calamita travelled up to 3.55 km, followed by H. molleri (2.84 km) and P. perezi (1.51 km). Pairwise F-ST estimates showed lower overall connectivity in P. cultripes. Average migration rates per generation were low in all species, with exceptions in same-slope populations of H. molleri and P. cultripes. Clustering algorithms consistently recovered well-differentiated population groups of P. cultripes in northern versus southern slopes, but widely admixed areas were observed in the other species, especially near mountain passes. Resistance by elevation surfaces showed a strong barrier effect of Sierra de Guadarrama in P. cultripes and suggested a potential role of topography in the genetic structure of E. calamita and H. molleri. Main conclusions: Sierra de Guadarrama currently acts as a strong barrier to gene flow for P. cultripes and, to a lesser extent, for E. calamita, H. molleri and P. perezi. This differential effect can be partly explained by differences in life history traits, including dispersal potential. Our findings support the general role of the Central System as a key feature shaping population connectivity and genetic variation in amphibian communities.

    Resumen
    This dataset gathers information about the macroinvertatebrate samples and environmental variables collected on rivers of the Ebro River Basin (NE Iberian Peninsula), the second largest catchment in the Iberian Peninsula. The collection is composed of 1,776 sampling events carried out between 2005 and 2015 at more than 400 sampling sites. This dataset is part of a monitoring network set up by the Ebro Hydrographic Confederation, the official body entrusted with the care of the basin, to fulfill the requirements of the European Water Framework Directive. Biological indices based on the freshwater macroinvertebrate communities were used to evaluate the ecological status of the water bodies within the basin. Samples were qualitatively screened for all occurring taxa. Then, all individuals from all taxa in a quantitative subsample of each sample were counted. Biological indices were calculated to estimate water quality at each sampling site. All samples are kept at the Museum of Zoology of the University of Navarra.

    Resumen
    The estimation of biodiversity is complex in remote areas like Andean-Amazon piedmont where the lack of knowledge is noticeable and most species have not yet been identified. An alternative to the taxonomical approach to assess biodiversity and community structure is to study the body size structure of the community. The present study aimed to identify systematic changes of the size structure of fish communities along the altitudinalgradient of pristine Andean streams. At the same time, we assessed if size structure of fish communities could be an alternative or complementary approach to traditional taxonomic metrics of ecological assessment. This study was conducted along two rivers of eastern Andean piedmont: Hacha River and Alto Madre de Dios basin. Our analysis showed lower values of total size range, maximum length and number of size classes in the highest places and increasing in lower reaches of the rivers. Concerning abundance size spectra, we found flatter slopes (indicating higher relative abundance of large fish) and lower coefficient of determination (i.e. less linear size spectra) and intercept at y-axis on upstream reaches. On the other hand, fish abundance, species richness and species diversity increasing from upstream to downstream. These systematic changes on size-related variables were similar using both basins together or independently and may be used in future studies as management reference conditions when assessing the effect of perturbations ...

    Two new species of Plutomurus, P. pichkhaiai sp. nov. from Garakha and Letsurtsume caves and P. shurubumuensis sp. nov. from Shurubumu Cave (Chkhorotsku district, Western Georgia) are described, and illustrated. The new species are very similar to P. kelasuricus from the Tsebelda karst massif formation in Apkhazeti, Georgia, but differ in having two inner spine-like chaetae on the inner edge of the hind tibiotarsus (only one in P. kelasuricus) and in occupying different, isolated cave formations separated by a geographic distance of nearly a 100 km. A key to the species of Plutomurus with 6 prelabral chaetae is provided.

    Resumen
    Knowledge of the fish assemblages of Andean mountain streams is restricted to accessible areas. This study is the first biological survey of the remote Suaza River in the Colombian Andes, at its source in the Cueva de los Guacharos National Park. Mechanistic insight into the ecological patterns and gradients of the river is provided, focusing on the spatial distribution of fish communities in relation to environmental variables and habitat characteristics. Electrofishing surveys and macroinvertebrate sampling were carried out, the river habitat was characterized, three environmental quality indices were applied, and potential water pollutant concentrations were measured. Twenty-seven fish species were recorded - two of them exotic (Poecilia reticulata and Xiphophorus hellerii) - as well as 45 macroinvertebrate families. Fish species richness was higher at lower altitudes with gentle slopes, where habitat temperature, size and heterogeneity were higher. Although macroinvertebrate diversity slightly increased downstream following a similar pattern as fish species richness, it declined at lower sites. Fish assemblages were distributed in three clusters corresponding to headwaters, middle sections and lower reaches of the river, showing correlations with environmental factors, suggesting habitat preferences. Although the headwaters of the Suaza River remains pristine inside the park, human influence is responsible for ecosystem alteration downstream.

    Resumen
    Drought-triggered declines in forest productivity and associated die-off events have increased considerably due to climate warming in the last decades. There is an increasing interest in quantifying the resilience capacity of forests against climate warming and drought to uncover how different stands and tree species will resist and recover after more frequent and intense droughts. Trees form annual growth rings that represent an accurate record of how forest growth responded to past droughts. Here we use dendrochronology to quantify the radial growth of different forests subjected to contrasting climatic conditions in Spain during the last half century. Particularly, we considered four climatically contrasting areas where dominant forests showed clear signs of drought-induced dieback. Studied forests included wet sites dominated by silver fir (Abies alba) in the Pyrenees and beech (Fagus sylvatica) stands in northern Spain, and drought-prone sites dominated by Scots pine (Pinus sylvestris) in eastern Spain and black pine (Pinus nigra) in the semi-arid south-eastern Spain. We quantified the growth reduction caused by different droughts and assessed the short-and long-term resilience capacity of declining vs. non-declining trees in each forest. In all cases, drought induced a marked growth reduction regardless tree vigor. However, the capacity to recover after drought (resilience) at short- and long-term scales varied greatly between declining and non-declining individuals. ..

    Resumen
    The native European freshwater cyprinid fish, common bleak Alburnus alburnus (Linnaeus, 1758), is an invasive non-native fish in the Iberian Peninsula, where it threatens the valuable endemic fish fauna. Despite the bleak's invasive status, there is a dearth of studies on the biological traits of non-native populations in Europe's Mediterranean region, and the present study aimed to compare bleak growth and reproductive traits across the principal rivers of Iberia with those from a native 'reference' bleak population in France. Non-native bleak from the River Tagus had the highest back-calculated total lengths (TLs), growth rate and body condition, but the lowest reproductive investment and smallest egg size of all studied populations. Whereas, these latter two traits were the highest in the River Ebro, where fecundity was the lowest for all Iberian rivers. The youngest age and the smallest TL at maturity were observed in the River Ebro. The River Segura had the lowest back-calculated TLs and growth rate, the highest fecundity and proportion of females, and the oldest age at maturity. Population traits of bleak in the River Saone (the native 'reference' population) were generally different from those in Iberian rivers, except for the River Ebro. This wide inter-population variability contributes to the species' successful establishment in novel habitats.

    Resumen
    Over the past decades, digitization endeavors across many institutions holding natural history collections (NHCs) have multiplied with three broad aims: first, to facilitate collection management by moving existing analog catalogues into digital form; second, to efficiently document and inventory specimens in collections, including imaging them as taxonomical surrogates; and third, to enable discovery of, and access to, the resulting collection data. NHCs contain a unique wealth of potential knowledge in the form of primary biodiversity data records (PBR): at its most basic level, the "what, where and when" of occurrences of the specimens in the collections. But as T.S. Eliot famously said, "knowledge is invariably a matter of degree". For such data to be transformed into digitally accessible knowledge (DAK) that is conducive to an understanding about how the natural world works, release of digitized data (the 2this we know") is necessary. At least two billion specimens are estimated to exist in NHCs already, but only a small fraction can be considered properly DAK: most have either not been digitized yet, or not released through a discovery facility. Digitizing is relatively costly as it often entails manually processing each specimen unit (e.g. a herbarium sheet, a pinned insect, or a vial full of invertebrates). How long could it take us to transform all NHCs into DAK? Can we keep up with the natural growth in collections?

    Resumen
    La calidad del aire urbano es un aspecto muy relevante para el bienestar de los ciudadanos y está cada vez más presente en el debate social y político. Para contar con una atmósfera saludable en nuestras ciudades, resulta necesario disponer de información detallada sobre cómo se distribuye la contaminación en cada punto de la ciudad y no solo en torno a las cabinas de control de calidad del aire. En este contexto, se inscribe el proyecto LIFE+ RESPIRA (2014-2017), concebido como una iniciativa de ciencia ciudadana, en la que cerca de 150 ciclistas voluntarios han recorrido el área metropolitana de Pamplona a lo largo de dos años, equipados con captadores geolocalizados de diferentes tipos de contaminantes atmosféricos (CO , NOX, O3 y partículas en suspensión). A lo largo de ese tiempo, los voluntarios han recorrido unos 47.000 km en bicicleta, contribuyendo a obtener casi 150 millones de medidas en más de 4 millones de posiciones geolocalizadas a lo largo de las calles de la ciudad y sus alrededores, cubriendo la mayoría de las situaciones estacionales, horarias, climáticas y de tráfico de un año típico. Con toda esa ingente cantidad de información se ha podido realizar gran cantidad de mapas muy detallados de la calidad del aire, que han permitido modelizar el comportamiento de cada contaminante estudiado de acuerdo a las diferentes condiciones que se presentan.

La lista está basada en la evaluación sistemática de los datos en colaboración con un amplio equipo de expertos de España y Portugal. Esta lista de actualización es un instrumento de apoyo importante para la aplicación del Reglamento de la Unión Europea (UE) sobre las especies exóticas invasoras (EEI) y también proporciona una base objetiva para el examen de su aplicación. En última instancia, la información incluida puede utilizarse para supervisar el cumplimiento del objetivo de la Estrategia de la UE sobre diversidad biológica hasta 2030 para combatir las EEI, pero también para la aplicación de otras políticas de la UE con requisitos sobre especies exóticas, como las Directivas de Hábitats y Aves, la Directiva Marco sobre la Estrategia Marina (DMEM) y la Directiva Marco del Agua (DMA).

Papel de la vegetación urbana en la calidad del aire 4. Modelos de alta resolución para evaluar la calidad del aire 5. Impactos de la contaminación urbana 6. Movilidad y sostenibilidad urbanas 7. Comunicación y educación ambiental. Este libro pretende ser una guía de utilidad para científicos, gestores y ciudadanos, aportando un conjunto de herramientas que permitan mejorar la calidad de vida de nuestras ciudades. Además, quiere rendir un homenaje a todos los voluntarios ciclistas que han participado en dicho proyecto y que son los verdaderos artífices del mismo, ya que gracias a su dedicación incondicional durante más de dos años, han proporcionado una cantidad ingente de datos sobre la calidad del aire de la ciudad de Pamplona.
