On the trail of the Arctic animals

Climate change is taking the Arctic into a new ecological state. To understand the consequences of the upheavals this region is undergoing, an international research consortium, including researchers from the Centre d’études biologiques de Chizé (CEBC – CNRS / University of La Rochelle) and the Littoral, Environnement et Sociétés laboratory (LIENSs – CNRS / University…

Pollution: the paradoxical effects of perfluorinated compounds on an Arctic gull

PFAS chemical molecules, also known as perfluorinated pollutants or eternal pollutants, are part of our everyday life. It has been shown since the 2000s that these elements contaminate ecosystems, even in areas far removed from human activities, such as the Arctic regions. However, a study by the Center for Biological Studies in Chizé and its…

Weeds at the service of agriculture

Two recent studies from the Disco-Weed project demonstrate the key role of weeds in the functioning of agricultural ecosystems. They also identify the measures to be implemented to promote their presence in the plots without harming agricultural production. The Disco-Weed research project was funded by the Foundation for Research on Biodiversity (FRB) and carried out…
