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.

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, ...

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 ¿this 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?

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.

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.

A methodology based on CFD-RANS simulations (WA CFD-RANS, Weighted Averaged Computational Fluid Dynamic-Reynolds¿Averaged Navier¿Stokes simulations) which includes appropriate modifications, has been applied to compute the annual, seasonal, and hourly average concentration of NO2 and NOX throughout the city of Pamplona (Spain) at pedestrian level during 2016. The results have been evaluated using measurements provided both by the city's network of air quality monitoring stations and by a network of mobile microsensors carried around by cyclists during their daily commutes, obtaining a maximum relative error lower than 30% when computing NO2 annual average concentrations. The model has taken into account the actual city layout in three dimensions, as well as the traffic emissions. The resulting air pollutionmaps provided information critical for studying the traffic-related health effects ofNO2 and their associated external costs in the city of Pamplona and the spatial representativeness of the current network of air quality monitoring stations (it has not been carried out for an entire city to date). The developed methodology can be applied to similar cities, providing useful information for the decision-makers.

The ratio of the effective number of breeders (Nb) to the adult census size (Na), Nb/Na, approximates the departure from the standard capacity of a population to maintain genetic diversity in one reproductive season. This information is relevant for assessing population status, understanding evolutionary processes operating at local scales, and unraveling how life-history traits affect these processes. However, our knowledge on Nb/Na ratios in nature is limited because estimation of both parameters is challenging. The sibship frequency (SF) method is adequate for reliable Nb estimation because it is based on sibship and parentage reconstruction from genetic marker data, thereby providing demographic inferences that can be compared with field-based information. In addition, capture-mark-recapture (CMR) robust design methods are well suited for Na estimation in seasonal-breeding species. We used tadpole genotypes of three pond-breeding amphibian species (Epidalea calamita, Hyla molleri, and Pelophylax perezi, n = 73-96 single-cohort tadpoles/species genotyped at 15-17 microsatellite loci) and candidate parental genotypes (n = 94-300 adults/species) to estimate Nb by the SF method. To assess the reliability of Nb estimates, we compared sibship and parentage inferences with field-based information and checked for the convergence of results in replicated subsampled analyses. Finally, we used CMR data from a 6-year monitoring program to estimate annual Na in the three species and calculate the Nb/Na ratio. Reliable ratios were obtained for E. calamita (Nb/Na = 0.18-0.28) and P. perezi (0.5), but in H. molleri, Na could not be estimated and genetic information proved insufficient for reliable Nb estimation. Integrative demographic studies taking full advantage of SF and CMR methods can provide accurate estimates of the Nb/Na ratio in seasonal-breeding species. Importantly, the SF method provides results that can be readily evaluated for reliability. This represents a good opportunity for obtaining robust demographic inferences with wide applications for evolutionary and conservation research.

Accurate characterization of genetic diversity is essential for understanding population demography, predicting future trends and implementing efficient conservation policies. For that purpose, molecular markers are routinely developed for nonmodel species, but key questions regarding sampling design, such as calculation of minimum sample sizes or the effect of relatives in the sample, are often neglected. We used accumulation curves and sibship analyses to explore how these 2 factors affect marker performance in the characterization of genetic diversity. We illustrate this approach with the analysis of an empirical dataset including newly optimized microsatellite sets for 3 Iberian amphibian species: Hyla molleri, Epidalea calamita, and Pelophylax perezi. We studied 17¿21 populations per species (total n = 547, 652, and 516 individuals, respectively), including a reference locality in which the effect of sample size was explored using larger samples (77¿96 individuals). As expected, FIS and tests for Hardy¿Weinberg equilibrium and linkage disequilibrium were affected by the presence of full sibs, and most initially inferred disequilibria were no longer statistically significant when full siblings were removed from the sample. We estimated that to obtain reliable estimates, the minimum sample size (potentially including full sibs) was close to 20 for expected heterozygosity, and between 50 and 80 for allelic richness. Our pilot study based on a reference population provided a rigorous assessment of marker properties and the effects of sample size and presence of full sibs in the sample. These examples illustrate the advantages of this approach to produce robust and reliable results for downstream analyses.

Background. Primary biodiversity records (PBR) are essential in many areas of scientific research as they document the biodiversity through time and space. However, concerns about PBR quality and fitness-for-use have grown, especially as derived from taxonomical, geographical and sampling effort biases. Nonetheless, the temporal bias stemming from data ageing has received less attention. We examine the effect of changes in land use in the information currentness, and therefore data obsolescence, in biodiversity databases. Methods. We created maps of land use changes for three periods (1956-1985, 1985-2000 and 2000-2012) at 5-kilometres resolution. For each cell we calculated the percentage of land use change within each period. We then overlaid distribution data about small mammals, and classified each data as 'non-obsolete or 'obsolete,' depending on both the amount of land use changes in the cell, and whether changes occurred at or after the data sampling's date. Results. A total of 14,528 records out of the initial 59,677 turned out to be non-obsolete after taking into account the changes in the land uses in Navarra. These obsolete data existed in 115 of the 156 cells analysed. Furthermore, more than one half of the remaining cells holding non-obsolete records had not been visited at least for the last fifteen years.

We describe the pellet sampling data set from the Vertebrate Collection of the Museum of Zoology of the University of Navarra. This data set compiles all information about small mammals obtained from the analysis of owl pellets. The collection consists on skulls, mandibles, and some skeletons of 36 species of more than 72,000 georeferenced specimens. These specimens come from the Iberian Peninsula although most samples were collected in Navarra, a highly diverse transitional area of 10,000¿kilometre square sitting across three biogeographical regions. The collection spans more than forty years and is still growing as a result of the establishment of a barn owl pellet monitoring network in 2015. The program will provide critical information about the evolution of the small mammals¿ community in this transition zone as it changes over time.

In this paper five datasets are described that provide information about records of mammals in the Vertebrate Collection of the Museum of Zoology of the University of Navarra (MZNA-VERT). The datasets contain 3,466 records belonging to 20 species of mammals sampled across the transition zone between the Atlantic and Mediterranean biogeographical regions (north Iberian Peninsula). The datasets include both distributional data (georeferenced records) and basic biometric data of most of the vouchered specimens stored in the museum facilities. The samples originated mainly within research projects and PhD theses carried out in the former department of Zoology and Ecology of the University of Navarra between 1982 and 2011. The Darwin Core Archive Format datasets are accessible through GBIF.

Despite many efforts by researchers worldwide to assess the biodiversity of plant groups, many locations on Earth remain not well surveyed and data-deprivation biases often occur. Robust estimates of inventory completeness could help alleviate the problem. This study aimed at identifying areas representing gaps in current knowledge of African palms, with a focus on Benin (West Africa). We assessed the completeness of knowledge of African palms targeting geographical distance and climatic difference from well-known sites. Data derived from intensive fieldwork were combined with independent data available online. Completeness inventory indices were calculated and coupled with other criteria to decide on the extent of knowledge. Results showed a high overall value for inventory completeness, as well as an even distribution of well-known areas across the country. However, poorly-known areas were distinctly identified and correlated to remote locations with low accessibility. This study illustrates how biodiversity survey and inventory efforts can be guided by existing knowledge. We strongly recommend the combination of digital accessible knowledge and fieldwork, coupled with expert knowledge, to obtain a better picture of the completeness of the inventory in tropical ecosystems.

The state of Hidalgo (Mexico) is an important region from the point of view of biodiversity. However, there exists a significant gap in accessible knowledge about species diversity and distribution, especially regarding to freshwater ecosystems. This dataset comprises the sampling records of two projects developed in Hidalgo between 2007 and 2009 about the freshwater fish communities of Tecocomulco lake and rivers belonging to the Metztitlan Canyon Biosphere Reserve. It contains the taxonomic identity (species level) and basic biometric data (total length and weight) as well as date of collection and coordinates of more than 9000 specimens. This dataset is the primary result of the first and unrepeated exhaustive freshwater fish's survey of Metztitlan Canyon Biosphere Reserve and Tecocomulco lake. It incorporates seven more species to the regional fish fauna, and new exclusive biometric data of ten species. This dataset can be used by studies dealing with, among other interests, North American freshwater fish diversity (species richness, distribution patterns) and biometric analyses, useful for the management and conservation of these areas. The complete dataset is also provided in Darwin Core Archive format.

The knowledge of species occurrence within an area is crucial to develop proper conservation strategies to protect species diversity. Biosphere Reserves (BRs), established to preserve biodiversity and sustainably use their resources, should therefore have precise information of its biodiversity. We compared and evaluated information on threatened and non-threatened vertebrate species available for Spanish BRs from three sources: management documents (MDs), the Global Biodiversity Information Facility index (GBIF), and atlases and red books. Our results suggest that information from any one source was rather partial, to a degree that depended on which vertebrate group was considered. Management documents did list a high percentage of threatened species found in BRs, reaching up to the total number of species of birds and mammals. Species lists overlap between all three sources ranged from 59 % for fish to 84 % for mammals. In addition, there is an inconsistency between national and international threatened species categories and it should thus call for revisions. Even though the information of non-threatened and threatened species occurrence in MDs of Spanish BRs is good, it is necessary to pay attention to amphibian and fish species which are less recorded.

The knowledge of biodiversity within an area is vital if we want to develop adequate conservation strategies. Biosphere Reserves are purposefully established for the sustainable use of their resources, and therefore their biodiversity should be well known. We compared and evaluated information available for Mexican Biosphere Reserves on threatened and non-threatened vertebrate species records from three different sources ¿ the corresponding Biosphere Reserves management plans (MPs), the Global Biodiversity Information Facility index (GBIF), and scientific literature, in order to find potential knowledge gaps. Our results suggest that there were varying gaps in information among sources according to vertebrate group. For each group of vertebrate species, management plans held the largest subsets of information but were not complete, ranging from 89.6% of the combined known species of birds to 70% for amphibians and freshwater fishes. However, both GBIF and literature included data absent from MPs, and GBIF included data not otherwise available, proving it as important as literature or other data sources (e.g. field data) used for crafting such plans. Moreover, we found references to threatened species that were not listed in the MPs, reaching to as many as 50% of the total known species of fish. Species information shared by all three sources ranged from 28% for amphibians to 72.5% for birds. Conservation efforts should therefore take into account that possibly less charismatic taxa such as amphibians, reptiles and freshwater fish lack more information than birds or mammals. The disparity observed in the vertebrate species information constitutes an information gap that could (or should) be solved by scientists and managers alike.

There are more than 267 million primary biodiversity data records published by hundreds of data publishers through the GBIF network. Thus, GBIF network is the single most comprehensive index for this kind of data. Ensuring or, at least, assessing data quality is of capital importance for the reliability and usability of this data. While conducting a time data gap analysis on this mass of data, we have detected some issues with the way date information is processed and shared. Dates can be obscured or altered under certain circumstances, when a specific combination of publisher¿s error or date handling features, and faulty or inadequate date parsing and processing routines gets chained together. The extent of the date unreliability (either at the source or through GBIF portal) is not high, and further it is concentrated in a few data publishers. We analyse the types of errors and misprocessing in dates through the sources and the published records; assess their impact on the overall data quality of the published index, and suggest corrective measures.

Freely available high quality, data on species occurrence and associated variables are needed in order to track changes in biodiversity. One of the main issues surrounding the provision of such data is that sources vary in quality, scope, and accuracy. Publishers of such data must face the challenge of maximizing quality, utility and breadth of data coverage, in order to make such data useful to users. With the Global Biodiversity Information Facility (GBIF), we recently conducted a content needs assessment survey to consolidate and synthesize major user needs regarding biodiversity data. We find a broad range of recommendations from the survey respondents, principally concerning issues such as data quality, bias, and coverage, and ease of access. We recommend a candidate set of actions for the GBIF that fall into three classes: 1) addressing data gaps, data volume, and data quality, 2) aggregating data types that are relatively new to GBIF, to support emerging new applications, and 3) promoting ease-of-use and providing incentives for wider use. Addressing the challenge of providing high quality primary biodiversity data potentially can serve the needs of national and international biodiversity initiatives. These include the ¿flexible framework¿ for addressing the new 2020 biodiversity targets of the Convention on Biological Diversity, the global biodiversity observation network (GEO BON) and the new Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Ser

A Content Needs Assessment (CNA) survey has been conducted in order to determine what GBIF-mediated data users may be using, what they would be using if available, and what they need in terms of primary biodiversity data records. The survey was launched in 2009 in six languages, and collected more than 700 individual responses. Analysis of the responses showed some lack of awareness about the availability of accessible primary data, and pointed out some types of data in high demand for linking to distribution and taxonomic data now derived from the GBIF cache. A notable example was linkages to molecular data. Also, the CNA survey uncovered some biases in the design of user needs surveys, by showing demographic and linguistic effects that may have influenced the distribution of responses received in analogous surveys conducted at the global scale.

With the establishment of the Global Biodiversity Information Facility (GBIF) in 2001 as an inter-governmental coordinating body, concerted efforts have been made during the past decade to establish a global research infrastructure to facilitate the publishing, discovery, and access to primary biodiversity data. The participants in GBIF have enabled the access to over 377 million records of such data as of August 2012. This is a remarkable achievement involving efforts at national, regional and global levels in multiple areas such as data digitization, standardization and exchange protocols. However concerns about the quality and `fitness for use¿ of the data mobilized in particular for the scientific communities have grown over the years and must now be carefully considered in future developments. This paper is the first comprehensive assessment of the content mobilised so far through GBIF, as well as a reflexion on possible strategies to improve its `fitness for use¿. The methodology builds on complementary approaches adopted by the GBIF Secretariat and the University of Navarra for the development of comprehensive content assessment methodologies. The outcome of this collaborative research demonstrates the immense value of the GBIF mobilized data and its potential for the scientific communities. Recommendations are provided to the GBIF community to improve the quality of the data published as well as priorities for future data mobilization.

In any data quality workflow, data publishers must become aware of issues in their data so these can be corrected. User feedback mechanisms provide one avenue, while global assessments of datasets provide another. To date, there is no publicly available tool to allow both biodiversity data institutions sharing their data through the Global Biodiversity Information Facility network and its potential users to assess datasets as a whole. Contributing to bridge this gap both for publishers and users, we introduce BIoDiversity DataSets Assessment Tool, an online tool that enables selected diagnostic visualizations on the content of data publishers and/ or their individual collections.

We characterize the primary biodiversity data records that have been made public for retrieval for the Pyrenean region. Such data, spanning more than a hundred years, have been collected by many institutions and individual researchers and digitized in databases, some of which have been shared through the Global Biodiversity Information Facility platform by using a standard format, Darwin Core. The datasets are not homogeneous in extent, coverage, taxonomy, or accuracy. Differences arising from taxonomic depth or group, georeferencing precision, age of collection, and other features result in biases and gaps that may influence the fitness for use of such data. Knowledge of patterns found in the data may help researchers and managers operating in the Pyrenees to estimate the reliability of available information and to assess what uses for the data are acceptable.

Mites and springtails are important members of soil mesofauna and have been proven to be good bioindicators of airborne pollutants. We studied the surrounding area of a steel mill located in a mountain valley of North Spain. Previous studies had documented the existence of a pollution gradient in this area due to the emissions of the factory, thus providing an interesting site to investigate the potential effects of pollutants (heavy metals and nitrogen) on soil biodiversity. The density of Acari and Collembola significantly decreased with the increase in concentration of Cr, Mn, Zn, Cd and Pb. Mites appeared to be more sensitive to heavy metal pollution than springtails. Likewise, the density of these microarthropoda was lower in those soils exhibiting higher nitrogen content. The species composition of the community of Acari and Collembola changed according to heavy metal pollution. Significant differences in abundance, species richness and diversity were observed between the communities of the sampling sites. Some species were exclusive of the less polluted sites, while other appeared in the most contaminated ones. This different response of soil mesofauna to pollutants suggests that some mite or springtail species could be used as bioindicators of heavy metal pollution.

A research on wildlife road-kills, mostly medium-sized mammals, has been conducted for two years along two highways (namely A-15 and A-10) in the Euro Siberian area of northwest Navarre (Northern Spain) between the westernmost side of the Pyrenees and the Basque Mountains. The study intended to find out a link between their distribution and the structure of the landscape surrounding it. The roads were segmented into 100-m stretches, and inspected weekly for roadkill by research staff with the collaboration of the maintenance service of both freeways. The data of the 539 animals recorded and geolocated in the segments were analysed spatially and matched to the surrounding landscape and presence of crossing structures. Results showed that the spatial distribution of wild medium-sized mammal road-kills along these freeways was not random, and that the surrounding landscape and the potential permeability of these roads did affect the road-kill rates. Existence of permeable crossings and heterogeneous landscape units reduced roadkill, while homogeneous agricultural and human landscapes increased roadkill rates.

The establishment of protected areas is one of the main tools used for biodiversity conservation, one of the components of environmental management. Although the theoretical framework for protected areas has been long known and discussed, there are few data about their practical effectiveness as a means to preserve biodiversity. Through the analysis of information from the Global Biodiversity Information Facility (GBIF), we have looked for any relationship between the protection status and the general species richness (i.e., number of all living species, taken as a surrogate for biodiversity) in the Spanish Pyrenees. We found that higher protection levels were associated to higher richness of non-endangered species. However, additional reliability tests have shown that for endangered species, the amount of currently available data may still be insufficient for effective management. To avoid this lack of reliability, enhancing public access to biodiversity data or improving sampling effort is mandatory.

This contribution explores the problem of recognizing and measuring the universe of specimen-level data existing in natural history collections around the world, and in absence of a complete, world-wide census or register. Estimates of size seem necessary to plan for resource allocation for digitization or data capture, and may help to represent how many vouchered primary biodiversity data (in terms of collections, specimens or curatorial units) might remain to be mobilized. It further helps to set priorities, and assess certainties. Three general approaches are proposed for further development, and initial estimates are given. Probabilistic models involve crossing data from a set of biodiversity datasets, finding commonalities and estimating the likelihood of totally obscure data from the fraction of known data missing from specific datasets in the set. Distribution models aim to find the underlying distribution of collections¿ compositions, estimating the hidden sector of the distributions. Finally, case studies seek to compare digitized data from collections known to the world to the amount of data known to exist in the collection but not generally available or not digitized. Preliminary estimates of size range from 1.2 to 2.1 gigaunits (109) of which a mere 3% at most is currently web-accessible through GBIF¿s mobilization efforts. However, further data and analyses, along with other approaches relying more heavily on surveys, might change the picture and possibly help to narrow the estimate further. In particular, unknown collections not having emerged through literature are the major source of uncertainty.

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.

Recoge los principales resultados generados durante la realización del proyecto LIFE+RESPIRA, llevado a cabo en la ciudad de Pamplona (Navarra, España) por un equipo interdisciplinar constituido por más de 30 investigadores pertenecientes a la Universidad de Navarra, el Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT) y Gestión Ambiental de Navarra (GAN-NIK). El libro, que se ha publicado en castellano y en inglés, se ha dividido en 7 capítulos: 1. ¿Ciudades sostenibles? 2. Exposición de los ciudadanos a la contaminación atmosférica 3. 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.

This best practice guide provides step-by-step approaches for conducting a user needs assessment. It describes an optimal workflow consisting of seven steps, viz. (1) setting up of purpose, scope and objectives of the study, (2) identifying the target audiences, (3) selecting a set of optimal and easy to implement methods, (4) identifying information needed and investigation methodology, (5) collection and analysis of the information, (6) synthesis of collected information and publishing results, and (7) develop and implement an action plan with an appropriate monitoring and evaluation mechanism. These steps are discussed with the help of eight representative biodiversity CNAs. While two of them have global coverage, six are national/regional in nature. These studies were examined for general trends. On the basis of this understanding, we provide a set of do¿s and don¿ts for each of the seven steps of CNA workflow. One aim of this guide is to help design optimal content assessment exercises ranging from global to national scale, with parsimonious investment of resources and time. As a result of these content assessment exercises, the biodiversity informatics community will be in a position to have a better understanding of its stakeholder communities. This will result in target-oriented and demand-driven data publishing policies and action plans.

Fitness-for-use refers to a scale of data quality that changes with the varying data accuracy, precision and intended use. In the context of geospatial data, we can split fitness-for-use into two broad categories: 1. Are the geospatial data correct? 2. Are the geospatial data usable at the geographic scale of the question? The key discussion point in this white paper is what can be done prior to user access of data to enhance and better report the data¿s fitness-for-use.
