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.

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.
