Research Group on Aquatic Ecology (EcoAqua)

The Research Group on Aquatic Ecology (EcoAqua) is one of the 17 research groups from the University of Girona (UdG) funded by the Government of Catalonia (as a Grup de Recerca Reconegut i Finançat per la Generalitat de Catalunya 2017-2019: 2017 SGR 548). It was also financially supported in 2014-2016: 2014 SGR 484). It includes most researchers from UdG attached to the Institute of Aquatic Ecology (IEA, UdG), which belong to groups GRCT002 (Molecular microbial ecologyand GRCT017 (Research Group on Ecology of Inland Waters (GRECO)) from UdG, and is composed from faculty of the Ecology (Department of Environmental Science) and Microbiology (Department of Biology) areas from UdG. EcoAqua is a large, interdisciplinary group, with extensive experience in many limnological areas such as microbial ecology, ecotoxicology, and ecology of a number of taxa, including bacteria, algae, invertebrates, and fish, both from rivers, lakes, reservoirs, and wetlands. Please check our publications and our research projects in this website.

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.
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.

Projecte Plastic0Pyr
El projecte Plastic0Pyr vol prevenir de manera sostenible l’acumulació de plàstics en els ecosistemes de muntanya, i evitar el seu transport cap al mar a través dels rius.
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.
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.
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.
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.
Biological Invasions
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.
