Reliability analysis of fish traits
Reliability analysis of fish traits reveals discrepancies among databases
Trait‐based approaches are commonly used in ecology to understand the relationship between biodiversity and ecosystem functioning, environmental filtering or biotic responses to anthropogenic perturbations. However, little is known about the reliability of assigned traits and the consistency of trait information among different databases currently in use.
Investigadors de la UdG alerten que les espècies introduïdes han augmentat un 30 % en aigües continentals
Han actualitzat la llista d’espècies establertes al medi ambient, introduïdes de manera intencionada, il·legal o per accident. Han detectat 27 espècies noves però han observat un estancament o disminució en les taxes des del punt de vista global.
Alien animal introductions in Iberian inland waters
Alien animal introductions in Iberian inland waters: An update and analysis
Inland waters provide innumerable ecosystem services and for this reason are among the most negatively impacted ecosystems worldwide. This is also the case with invasive alien species, which have enormous economic and ecological impacts in freshwater ecosystems.

Amphibians of North Africa is a comprehensive compilation of available data on the amphibians and reptiles found in various ecosystems across North West Africa and parts of the Mediterranean region.
Resident (DNA) and active (RNA) microbial communities in fluvial biofilms
Responses of resident (DNA) and active (RNA) microbial communities in fluvial biofilms under different polluted scenarios
Pollution from human activities is a major threat to the ecological integrity of fluvial ecosystems. Microbial communities are the most abundant organisms in biofilms, and are key indicators of various pollutants.
Relationships of critical swimming speed Ucrit (a), maximal metabolic rate MMR (b) and absolute aerobic scope AAS (c) with fish mass for Spanish toothcarp, Aphanius iberus (N = 28) and mosquitofish, Gambusia holbrooki (N = 60).
Differences in swimming performance and energetic costs between an endangered native toothcarp (Aphanius iberus) and an invasive mosquitofish (Gambusia holbrooki)
Swimming performance is a key feature that mediates fitness and survival in many fish species. Using a swim tunnel respirometer, we compared prolonged swimming performance and energy use for two competing species: an endangered, endemic toothcarp (Aphanius iberus) and a worldwide invasive mosquitofish (Gambusia holbrooki).
Fish and Fisheries
Effective monitoring of freshwater fish
Freshwater ecosystems constitute only a small fraction of the planet's water resources, yet support much of its diversity, with freshwater fish accounting for more species than birds, mammals, amphibians or reptiles. Fresh waters are, however, particularly vulnerable to anthropogenic impacts, including habitat loss, climate and land use change, pollution and biological invasions.

Ramon Margalef
2019 Any Margalef. Centenari del naixement de Ramon Margalef
Ramon Margalef va ser un dels ecòlegs més importants del segle XX, quan aquesta branca de la ciència s’estableix com a pròpia. Amb nombrosos premis i reconeixements internacionals, és un dels científics més il·lustres que ha donat el nostre país.
impact assessment protocols for non-native species
Consistency of impact assessment protocols for non-native species
Standardized tools are needed to identify and prioritize the most harmful non-native species (NNS). A plethora of assessment protocols have been developed to evaluate the current and potential impacts of non-native species, but consistency among them has received limited attention.

Ebro River fish
Environmental filtering governs the spatial distribution of alien fishes in a large, human‐impacted Mediterranean river
To analyse the occurrence and abundance of native versus alien fish species in relation to climate, land use, hydrologic alteration and habitat fragmentation in a heavily invaded and human‐impacted riverine ecosystem. To test whether co‐occurrence patterns of native versus alien species are structured by environmental filtering or biotic associations.

Identifiquen 66 espècies exòtiques que amenaçaran la biodiversitat europea en els propers anys
Els científics han identificat espècies vegetals i animals exòtiques, encara no establertes a la Unió Europea, que representen la major amenaça potencial per a la biodiversitat i els ecosistemes de la regió.

Global Change Biology
Susceptibility of European freshwater fish to climate change: species profiling based on life-history and environmental characteristics
Climate change is expected to strongly affect freshwater fish communities. Combined with other anthropogenic drivers, the impacts may alter species spatio-temporal distributions, and contribute to population declines and local extinctions.
pond metacommunities
Dispersal mode and spatial extent influence distance-decay patterns in pond metacommunities
Assuming that dispersal modes or abilities can explain the different responses of organisms to geographic or environmental distances, the distance-decay relationship is a useful tool to evaluate the relative role of local environmental structuring versus regional control in community composition.
Bilayer Infiltration System
Bilayer Infiltration System Combines Benefits from Both Coarse and Fine Sands Promoting Nutrient Accumulation in Sediments and Increasing Removal Rates
Infiltration systems are treatment technologies based on water percolation through porous media where biogeochemical processes take place. Grain size distribution (GSD) acts as a driver of these processes and their rates and influences nutrient accumulation in sediments.
SUDOANG project - Promoting the concerted and sustainable management of eels in the SUDOE area
During the last 40 years, the European eel population has experienced a decline that has led it to move beyond the biological limits of security (ICES 1998) and to be considered as critically endangered (IUCN).
