When a freshwater invader meets the estuary: the peacock bass and fish assemblages in the São João River, Brazil
Peacock basses (Cichla spp.) are native to the Amazon basin but introduced to different parts of the world. Almost thirty years ago, Cichla kelberi was introduced in an impoundment of the São João River, a coastal system in southeastern Brazil.

PONDERFUL: Pond Ecosystems for Resilient Future Landscapes in A Changing Climate
PONDERFUL is an EU project bringing 11 EU and CELAC Countries Worldwide with the aim of facilitating improved implementation of ponds and pondscapes as Nature-Based Solutions (NBS) for climate change (CC) mitigation and adaptation, biodiversity conservation and delivery of ecosystem services (ES). GRECO/EcoAqua is one of the partners.

El canvi climàtic alterarà la distribució dels peixos de l’Ebre i afavorirà les espècies invasores
Investigadors del Grup de recerca en Ecologia aquàtica continental han modelat la distribució de 16 espècies de peixos a tota la conca de l’Ebre i la seva resposta futura al canvi climàtic

The role of connectivity in the interplay between climate change and the spread of alien fish in a large Mediterranean river
Understanding how global change and connectivity will jointly modify the distribution of riverine species is crucial for conservation biology and environmental management. However, little is known about the interaction between climate change and fragmentation and how movement barriers might impede native species from adjusting their distributions vs. limit the further spread of alien species.

A workflow for standardising and integrating alien species distribution data
Biodiversity data are being collected at unprecedented rates. Such data often have significant value for purposes beyond the initial reason for which they were collected, particularly when they are combined and collated with other data sources

Addressing trait selection patterns in temporary ponds in response to wildfire disturbance and seasonal succession
Mediterranean ecosystems are increasingly threatened by disturbances such as wildfires. These disturbances are expected to shift the selective pressures that determine trait‐dependent community assembly.

Captive breeding conditions decrease metabolic rates and alter morphological traits in the endangered Spanish toothcarp Aphanius iberus
Physiological features of species can determine the resilience and adaptation of organisms to the environment. Swimming capacity and metabolic traits are key factors for fish survival, mating and predator‐prey interactions.

Organization of Squamata (Reptilia) assemblages in Mediterranean archipelagos
Mediterranean islands have complex reptile assemblages, but little is known about the factors that determine their organization. In this study, the structure of assemblages of Squamata was evaluated based on their species richness and two measures of phylogenetic diversity (variability and clustering).
Microbes inhabiting intermittent streambeds
Multi‐model assessment of hydrological and environmental impacts on streambed microbes in Mediterranean catchments
Microbes inhabiting intermittent streambeds are responsible for controlling and developing many biogeochemical processes essential for the ecosystem functions. Although streambed microbiota is adapted to intermittency the intensification of water scarcity and prolonged dry periods may jeopardise their capacity to cope with hydrological changes

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.

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.

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.

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.
