To many lay people, a small red woollen cap identifies a diver in a photograph of marine theme. Jacques-Yves Cousteau and his crew almost invariably wore them in his movies. Were red caps trade-marks, insignias of divers? Well, no, for black caps were the unspo-ken norm among divers. But at some time, or so legend has it, Cous-teau settled for red...

This contribution explores the problem of recognizing and measuring the universe of specimen-level data existing in Natural History Collections around the world, 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 represent how many...

Much ecology considers only the typical size of a population, yet extreme values may be of particular importance. Unusually low numbers may doom a population to extinction and unusually high numbers may pose an economic threat. Extreme values may also determine the evolutionary traits that predominate. Obviously, even for a fixed variance in annual...

Biodiversity informatics is a relatively new discipline extending computer science in the context of biodiversity data, and its development to date has not been uniform throughout the world. Digitizing effort and capacity building are costly, and ways should be found to prioritize them rationally. The proposed 'Biodiversity Informatics Potential (B...

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 mod...

Up-to-date reporting of atmospheric pollen contents is essential to assist doctors and allergy sufferers alike to undertake treatment or preventative measures. We have evaluated the extent of the digitally accessible knowledge (DAK) created by the Spanish network of pollen monitoring stations and analyzed the gaps in three main DAK factors: data co...

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 pu...

It is known that indoor air is affected by outdoor air, thanks to the various studies that have been conducted in this area, the causes can be varied, from infiltration of buildings, natural or mechanical ventilation. Although it is known that transportation is one of the major contributors to this problem, studies have concluded that there is a pr...

Abstract: Tens of millions of images from biological collections have become available online in the last two decades. In parallel, there has been a dramatic increase in the capabilities of image analysis technologies, especially those involving machine learning and computer vision. Whilst image analysis has become mainstream in consumer applicatio...

The identity of a biological specimen can be considered the most basic type of trait: the species (or higher taxon) the specimen belongs to, one of the three most fundamental data elements (along with location and time) that configure the primary biodiversity data record whose quantification may underpin biological monitoring programs. A general im...

Among the sources of urban air pollution, the gases and airborne particles coming out from residential buildings through normal ventilation outlets are often neglected or poorly understood. Yet, it carries the potential to deeply affect urban air quality, given the universal ubiquity and function of dwellings. The climate emergency declaration appr...

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. H...

The "Safe Campus Program," implemented in 2020 through 2021 at the University of Navarra (Spain), aimed to guarantee a safe return to university campus and prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks, avoiding university-wide lockdown. It included COVID-19 education, campus adaptation, and polymerase chain reactio...

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 fr...

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 preve...

Hace ya cinco años que España ratificó el Acuerdo de París sobre el clima, pero es ahora cuando se ha aprobado la Ley de Cambio Climático y Transición Energética. Cabe esperar que la redacción de la ley no haya estado sometida a la misma premura que su periplo parlamentario. La extensa lista de prescripciones y proscripciones del texto busca deten...

Zoos and aquaria, often regarded as preservation‐cum‐entertainment enterprises, are now touted as actors in the efforts to curb the biodiversity crisis: raising awareness, supporting conservation, and conducting research. We have tested whether data grant this claim by assessing the research carried out by zoos on a global scale. For the zoos and a...

Significance Coexposure to airborne pollen enhances susceptibility to respiratory viral infections, regardless of the allergy status. We hypothesized this could be also true for SARS-CoV-2 infections. To investigate this, we tested for relationships between SARS-CoV-2 infection rates and pollen concentrations, along with humidity, temperature, popu...

Pollen monitoring data from Navarra during 2019 and 2020

Aquatic biodiversity is severely jeopardized by human actions. Among all vertebrates that live in aquatic environments, fish species are the most diverse and essential for the role they play in aquatic ecosystems. Fish conservation status had been partially and increasingly assessed by the IUCN Red List, but they still remain much less assessed tha...

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 grea...

This is a very simple model that looks at the velocity of change of the rate of increase of the covid-19 case counts, and predicts dates to reach certain numbers if the exponential phase of the growth curve were to continue. As the curves slow down the dates are delayed and the extent of the delay is a proxy to assess the slowdown of the expansion....

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 assessm...

Proceedings of the Biodiversity_Next Conference, Leiden 2019

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...

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...

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...

Building on the development of Biodiversity Informatics, the Global Biodiversity Information Facility (GBIF) undertook the task of enabling access to the world’s wealth of biodiversity data via the Internet. To date, GBIF has become, in many respects, the most extensive biodiversity information exchange infrastructure in the world, opening up a ful...

Critical as they are for humans and nature, freshwater ecosystems are threatened—but the extent and depth of these threats are not well understood, especially if essential biodiversity data are lacking. Any policy aimed at protecting such ecosystems must first assess the threat factors and the potential harm, well before proposing conservation meas...

To test the role of mountains as barriers to gene flow in co-distributed taxa with different life history traits. Sierra de Guadarrama, Central Spain. 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 desc...

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 unr...

This book collects the main outcomes that were generated during the implementation of the LIFE+RESPIRA project (LIFE13 ENV/ES/000417), carried out in the city of Pamplona, Navarra, Spain. The research was conducted by a cross-functional team made up of more than 30 researchers belonging to three entities: The University of Navarra, the Centre for E...

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 non-model species, but key questions regarding sampling design, like calculation of minimum sample sizes or th...

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...

The guide illustrates general practices by summarizing 16 actual DGA exercises, with six focused on GBIF-mediated data discussed in detail. This guide is intended to support biodiversit...

It is almost paradoxical that as more biodiversity data become widely available and interoperable, the wail for missing, critical information becomes louder. The maturity of biodiversity data standards, coupled with increasingly sophisticated data mining techniques and ongoing literature markup and semantic indexing, allows even easier detection an...

Wild palms (family Arecaceae) are useful species with significant cultural, social, economic, and ecological uses. They also serve as bio-indicators, and their occurrences could be used as climate trend proxies. In Benin they are part of the nation’s 3,000-species flora but had not been well assessed. A complete richness inventory and knowledge of...

Despite efforts by researchers worldwide to assess the biodiversity of plant groups, many locations on Earth remain poorly surveyed, resulting in inadequate or biased knowledge. Robust estimates of inventory completeness could help alleviate the problem. This study aimed to identify areas representing gaps in current knowledge of African palms,...
