Chloé VAGNON

FRB-CESAB - Post-doc

Chloé VAGNON joined the FRB at Cesab in September 2024 as a postdoctoral researcher within the FOOD-WEBS group. This project aims to understand how biodiversity and freshwater ecosystems respond to global changes by using an unprecedented global database compiling stable isotope values at both the species and individual levels. These data will be used to:
i) better understand the global structure of trophic networks,
ii) determine the importance of intraspecific variability within these networks, and
iii) quantify how energy transfers are affected by global changes.

 

Chloé completed her PhD at the University Savoie Mont Blanc, where she studied the invasion of the European catfish (Silurus glanis) in large Alpine lakes and its impact on biodiversity, combining empirical approaches (stomach content analysis, stable isotopes, and DNA) and theoretical approaches (niche modeling, food-web analyses, and population dynamics and stability). She then pursued a postdoctoral fellowship at CRBE in Toulouse, focusing on the dynamics of freshwater ecosystems and the synchronization of their responses to environmental disturbances.

 

More broadly, her research seeks to understand and predict the impact of global change on ecosystem functioning, by integrating different levels of biological organization and multiple spatial and temporal scales.
