Specializace

My PhD research is dedicated to understand how freshwater ectotherm populations respond to climatic and habitat changes by accounting mechanisms that are implied from individual to community scales. Through the development of predictive population models, I especially aim to understand the key role of species body sizes and environmental drivers (warming and eutrophication) on individual life histories and communities structure and persistence. Mainly theoretical, my models exclusively involve multitrophic interactions (predation, competition and omnivory), life history traits, temperature- and mass-dependent relationships, and fast/slow climatic processes (season vs. long-term warming).
