Prioritizing Sex Recognition Over Learned Species Recognition: Hierarchical Mate Recognition in an Invasive Fish
Mate recognition is the process of identifying and assessing the appropriate species, sex or population of another individual for their suitability as a potential mate.
Graphical Abstract
Interspecific synchrony is related to body-length similarity in a fish community under prolonged drought conditions
Interspecific synchrony and trait-based differences between species are likely to be related to each other.

Graphical Abstract
Effects of reservoir cascades on diversity, distribution, and abundance of fish assemblages in three Neotropical basins
River systems are characterized by the existence of longitudinal processes structuring fish assemblages.
Cladocerans - Font: Wikipedia
Diel changes in vertical and horizontal distribution of cladocerans in two deep lakes during early and late summer
Temporal and spatial heterogeneity in the distribution of cladocerans in lakes could be caused by abiotic (wind, water currents) and biotic factors (reproduction, food resources, predation).

River biofilms adapted to anthropogenic disturbances are more resistant to WWTP inputs
River biofilms adapted to anthropogenic disturbances are more resistant to WWTP inputs
The sensitivity and spatial recovery of river sediment biofilms along 1 km after the input of two wastewater treatment plants (WWTPs) located in two river reaches with different degrees of anthropogenic influence were investigated.

Ingesta de microplásticos por el pez exótico Gambusia holbrooki en dos lagunas costeras mediterránea
Gambusia holbrooki es un pequeño pez Poecílido, de origen norteamericano que fue introducido a principios del siglo XX en humedales de la Península Ibérica para el control biológico de los mosquitos.
Actualmente presenta poblaciones en muchos humedales y está considerada como una de las principales especies invasoras en la península.
Graphical Abstract
Electro-bioremediation of nitrate and arsenite polluted groundwater
The coexistence of different pollutants in groundwater is a common threat. Sustainable and resilient technologies are required for their treatment.

"A ciència certa", el primer podcast de l'Institut d'Ecologia Aquàtica
Aprofitant la Setmana de la Ciència i la Nit de la recerca d’enguany, des de l’Institut d’Ecologia Aquàtica de la UdG hem volgut posar a la vostra disposició un podcast per què conegueu millor qui som, el tipus de recerca que fem i alguns dels principals projectes on participem.
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.
Effects of high nitrate input in the denitrification-DNRA activities in the sediment of a constructed wetland under varying C/N ratios
In constructed wetlands (CW), denitrification usually accounts for >60% of nitrogen removal and is supposedly affected by the inflow water and the wetland management practices.

Bacteria coated cathodes as an in‑situ hydrogen evolving platform for microbial electrosynthesis
Hydrogen is a key intermediate element in microbial electrosynthesis as a mediator of the reduction of carbon dioxide (CO2) into added value compounds.
Typha root - (CC) Antropology from the shed
Limited effect of radial oxygen loss on ammonia oxidizers in Typha angustifolia root hairs
The benefits of plant–microbe interactions have been exploited extensively for nutrient removal. Radial oxygen loss in aquatic macrophytes potentially promotes nitrification and accelerates nitrogen removal through coupled nitrification–denitrification process.

Key factors explaining critical swimming speed in freshwater fish: a review and statistical analysis for Iberian species
Swimming performance is a key feature that mediates fitness and survival in aquatic animals.

Dispersal, habitat selection, predator–prey interactions and reproduction are processes that depend on swimming capabilities.
Ecological impacts of an invasive top predator fish across South America
Ecological impacts of an invasive top predator fish across South America
Peacock bass Cichla ocellaris is a piscivorous cichlid native from the Amazon and Orinoco river basins, which has been broadly introduced into tropical areas worldwide, leading to several adverse local effects.
Barbus Meridionalis (CC) Lluis Zamora
Antioxidant system status in threatened native fish Barbus meridionalis from the Osor River (Iberian Peninsula): I. Characterization and II. In vitro Zn assays
The evaluation of antioxidant system capacity is important in aquatic toxicology. It was aimed to characterize the liver antioxidant enzymes (SOD, CAT, GPX, GR, and GST) and to test the in vitro Zn effect (200 and 400 ZnSO4 μg/L) in native fish Barbus meridionalis obtained from the Osor River (NE, Spain) influenced by Zn contamination.

Ecosystem metabolism dynamics and environmental drivers in Mediterranean confined coastal lagoons
Aquatic metabolism is an important descriptor of ecosystem functioning. The metabolism of ponds and confined coastal lagoons has been poorly studied in comparison to other aquatic systems, in which the metabolic dynamics are better understood.

Kicking-off the "Viable Bacteria Quantification Kit" Cost Action project
In the food industry, the presence of bacteria is a major safety concern because they can affect the product quality or even lead to health risks. It is known that an increased denstiy of living cells singificanlty increases the risk of biofilm formation and at the same tame viable cell density may indicate the release of living cells from biofilms attached in the closed circuit pipes.
Pairwise relationships between selected limnological predictors and the metrics of native and alien fish species.
Alien fish in Neotropical reservoirs: Assessing multiple hypotheses in invasion biology
Invasive alien species (IAS) are one of the main components of global ecological change, the second known cause of animal extinctions, and very costly in terms of ecosystem services. IAS and damming are two of the most impacting alterations in freshwater ecosystems. Understanding the processes that govern biological invasions in these habitats is of enormous conceptual and practical importance.

PONDERFUL: Pond Ecosystems for Resilient Future Landscapes in A Changing Climate
GRECO/EcoAqua is part of a consortium that is running a new Horizon 2020 project ‘PONDERFUL’, led by the University of Vic (Spain). The project’s overarching aim is to develop improved methods for maximising the use of ponds and pondscapes in climate change adaptation and mitigation, biodiversity conservation and the delivery of ecosystem services.

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.

Dams exacerbate the consequences of climate change on river fish
A potential response of river fish to environmental changes is to colonize new habitats. But what happens when dams and weirs restrict their movement?

Global Change Biology
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
