Arsenic Biogeochemistry
Biotic and Abiotic Factors Influencing Arsenic Biogeochemistry and Toxicity in Fluvial Ecosystems: A Review
This review is focused on the biogeochemistry of arsenic in freshwaters and, especially,
on the key role that benthic microalgae and prokaryotic communities from biofilms play together
in through speciation, distribution, and cycling.

Size-related effects and the influence of metabolic traits and morphology on swimming performance in fish
Energy metabolism fuels swimming and other biological processes. We compared the swimming performance and energy metabolism within and across eight freshwater fish species.

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.

New paper in SciRep: insights in oocyte dynamics shed light on the complexities associated with fish reproductive strategies
In our new paper published in Scientific Reports we give insights in oocyte dynamics that shed light on the complexities associated with fish reproductive strategies. Our results suggest that an species previously considered indeterminate, perform a low-cost predefinition; and that the potential fecundity estimation should be complemented with primary oocyte dynamics.
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.
What's going on with the sardine in the NW Mediterranean Sea?
Researchers from GRMAR_UdG and LIG_UdG from the University of Girona start a study relating the condition, reproduction, parasitism and genètics of sardine, with the aim to understand the decline of its captures.
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.

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.
