Fish in dry streams: from individual and social behavior to population persistence (DRYFISH)

DRYFISH

Investigating the effects of droughts on freshwater fish populations. The research project seeks to understand how individuals and groups of fish cope with severe droughts.

Investigating the effects of droughts on freshwater fish populations. The research project seeks to understand how individuals and groups of fish cope with severe droughts and how phenotypic variation can affect population structure and resilience.

Research in the framework of global change: how animals adapt to it, change their behavior.

Field work is carried out in streams and rivers in La Garrotxa and near Girona, Catalonia, Spain. Experimentation is also carried out under controlled conditions in the CEAB laboratories, at the LEOV.

Mitigation of diffuse nitrate pollution from agricultural sources through the recovery of ecological functions (ENEO3)

By studying the relationship between rivers, aquifers, and terrestrial environments, ENEO3 examines how natural self-purification processes can help improve water quality. The project focuses on denitrification, a key biogeochemical process that converts nitrates into nitrogen gas, thereby reducing water pollution caused by excess nitrogen.

BlauCat-Current Status and Action Plan for Blue Carbon in Catalonia

The BlauCat project aims to assess the current status of blue carbon in Catalonia’s coastal ecosystems and contribute to the development of an action plan for their conservation and restoration, as a tool to support public policies for climate change mitigation and adaptation. The project will generate a homogeneous and georeferenced database on blue carbon stocks and fluxes at the regional scale, as well as an analysis of the restoration potential of these ecosystems.

Digital twins for the prediction and management of water quality and coastal dynamics in the internal basins of Catalonia

The main objective of this research project is to co-develop digital twins for predicting water quantity and quality in the Ter and Tordera basins, including catchments, reservoirs and coastal areas, contributing to efficient water resource management, protecting ecosystems and maximising water security in a climate change context.
