Ocean Degradation: A Crazy Story

The global seabird population has halved over the last five decades. The decline of the Northern Gannet, although among the most resilient, indicates that the level of disturbance to marine ecosystems is reaching a critical threshold. This worrying alarm signal must lead to the urgent transformation of maritime policies, particularly on fisheries. Publication cited in…

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…
