Restoration of biodiversity in agricultural areas via innovative agricultural practices

Different innovative agricultural practices exist, like mixed cropping, cover crops or reduced tillage, and could improve biological diversity in farmland ecosystem. This doctoral project will focus on the effect of such practices on different levels of the ecosystem, and aim to identify solutions which could benefit farmland species while being accepted by farmers.

Co-Evolution of Social Organization and Longevity in Ants

My thesis project aims to understand how the social organization of ants can influence the longevity and/or the aging rate of individuals, depending on their social role (queen, in/outside worker). To this end, I will use diverse tools, such as Social Network Analysis, mass spectrometry, and computer-based modelling.

Trophic ecology of the green turtle (Chelonia mydas) in the Caribbean: role on ecosystem dynamics in a colonization context of the invasive phanerogam Halophila stipulacea

We aim at studying the impact of the green turtle on the development of an alien flowering plant by describing the trophic ecology of these animals. GPS and direct observations of animals, associated to vegetation surveys, will help defining turtles’ fine-scale habitat use patterns. Feeding preferences will then be inferred from stable isotope analysis
