Research I am a phD student in molecular ecology. My research aims at understanding how biodiversity at the intra-specific level (genetic and epigenetic diversity) affects ecosystem functioning. My thesis focuses on three species (Alnus glutinosa, Gammarus fossarum and Phoxinus phoxinus) living in fluvial ecosystems and interacting within a food web (from producers to secondary consumers). More specifically, my research is divided in tree tasks (i) describing genetic and epigenetic diversity patterns in natural environments within each target species and identifying the main processes generating these patterns; (ii) testing the heritability of those molecular traits in a target species : Gammarus fossarum; (iii) developing a molecular metric of biodiversity (a) that is measurable both at the intra- and interspecific level and (b) that is directly related to the effects of organisms on their resources, to allow predictions on the ecosystem functioning. Ultimately, my thesis will contribute to further integrate intraspecific diversity within the BEF framework and develop a new approach to measure these links by reconciling intra- and interspecific approaches. This project is funded through an ANR project carried by Simon Blanchet.
