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 s...
Article
Zoos and aquariums have evolved significantly. From their origins as enclosures for the mere entertainment of the public, these institutions have undertaken new functions responding to the biodiversity crisis and social demands. Modern zoos and aquariums have the opportunity to educate people, contribute to species conservation, and produce animal-...

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 i...

Full-text available
Abstract: The introduction of invasive alien species (IAS) is a serious global problem in ecosystems that affects biodiversity and represents a severe threat to endemic species. This situation is espe-cially worrying in the Iberian Peninsula since Spain and Portugal’s rivers and lakes host a unique wealth of endemic freshwater species. Ignorance ab...
Chapter
Fishes constitute the most species-rich group of vertebrates. They inhabit all kind of marine and freshwater ecosystems and have concentrated a high species diversity in several hotspots all around the world. Here, we explore the conservation status of freshwater fishes in one of these hotspots, the Iberian Peninsula, in South Western Europe. Iberi...

Climate change is rearranging the mosaic of biodiversity on our planet. These broad-scale species re-distributions will affect the structure of communities across multiple biodiversity facets (taxonomic, phylogenetic, and functional diversity). The current challenges to understand such effects involve focusing on organisms other than vertebrates an...

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, us...
Article
Full-text available
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...
Article
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, bec...
Article
Full-text available
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...

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...

Full-text available
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 co...

Article
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...

Thesis
Full-text available
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...

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 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 popul...

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 geneti...

The monitoring of freshwater ecosystems has been central to environmental policies across the world. Biological indexes based on macroinvertebrates are widely used to assess the ecological status of inland waters. Traditional methods consist of obtaining samples and identifying macroinvertebrates up to family level using morphological characters. H...

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...

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...

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 (H...

During the chick-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 JMLC energetic prey, i.e. larger prey or prey with relatively higher caloric values. The...

Many human activities in and on rivers cause the loss of freshwater biodiversity, especially fish, which now are one of the most endangered vertebrate groups. River fragmentation caused by the construction of dams is one of the main threats to fish species. In Spain, which has the highest number of dams per square kilometre in the world, more than...

Environmental conditions and host features that influence the abundance of an exotic branchiobdellidan were studied. One of the most widespread invasive crayfish species in Europe is the signal crayfish, Pacifastacus leniusculus (Dana, 1825). Along with this invasive crayfish, other alien species that live on the crayfish’s body surface, such as ba...
