My three research themes, past and present, are linked to a more and more assertive research approach at the science-society interface. They consist of the study of:
(i) the viability of populations, flows of individuals and their genes within anthropised landscapes,
(ii) eco-evolutionary dynamics of biodiversity and ecosystem services in agroecosystems
(iii) human / non-human trajectories scenarios in conservation sciences.
My first research deals with the study of population dynamics and dispersal processes in fragmented landscapes. Approaching them through a metapopulation approach has allowed me to link population dynamics at the local scale to patterns and processes occurring at the landscape scale. In parallel with the studies on the demographic functioning of viviparous lizard populations, this work aimed to (1) shed light on the key factors (density, competition and dispersal) that can influence individual behavior and population dynamics and (2) study the influence of habitat fragmentation on demographic characteristics and dispersal patterns.
The second part of my research consisted in estimating the ecological risks related to the cultivation of transgenic plants by developing an approach based (1) on the long-term monitoring of pollen and rapeseed flows in an agroecosystem. model, (2) the development of methods of analysis of these data, (3) the establishment of targeted experiments and (4) the construction of models allowing the construction of scenarios aiming, in particular, to evaluate the conditions of coexistence of cultures. transgenic with other farming methods in European agroecosystems.
The research I’m currently doing involves:
- eco-evolutionary dynamics of biodiversity and ecosystem services in agroecosystems. This research aims at a better integration of knowledge in ecology for the establishment of a less impactful agriculture for biodiversity. As part of a transition from conventional farming systems to agroecology, this research aims to study, on the one hand, the modalities and, on the other hand, the ecological and evolutionary consequences of the mobilization of biodiversity in cultivated systems.
- interdisciplinary work on the development of human / non-human trajectory scenarios in collaboration with ecologists, philosophers, sociologists and anthropologists. This work led me to develop with François Sarrazin (Sorbonne University) a so-called evocentric ethic. This research aims to jointly consider human sciences and evolutionary approaches in order to generate new research perspectives, recommendations for conservation action and taking into account the constraints and challenges of their implementation.
