PhD Project : Influence of the urban environment on the circadian rhythms of wild great tits and mice
Urbanisation transforms natural habitats into artificial environments, deeply disrupting ecosystems. Urban light, noise, and pollution alter animal activity patterns and affect internal biological clocks. The project project aims to understand how urban night conditions influence circadian mechanisms, through plasticity or genetic adaptation, in two model species: the great tit (Parus major, diurnal) and the house mouse (Mus musculus, nocturnal). By linking ecological, behavioral, and physiological effects, the project seeks to uncover how urban life drives the evolution of biological rhythms.
This PhD is part of an interdisciplinary project (IDIL – POLLUNOCT), in which two theses address the same questions from different perspectives and disciplines. While my approach focuses on evolutionary ecology, Maxence Boissonade’s work explores the neurophysiological aspects of circadian rhythms.

Current Project
My PhD research takes a biogeographical approach and aims to characterize the spatial distribution of seabird communities along the latitudinal gradient of the Southern Ocean.
It also seeks to identify the underlying ecological mechanisms structuring these assemblages within an environment that, on the surface, appears homogeneous.
A better understanding of these biogeographical dynamics will enable us to refine their mapping and thus identify key areas for the conservation of seabirds and associated food webs

Short Bio
With an engineering background in agronomy (ENSAIA), I reoriented my career towards ecology, focusing on my areas of interest, i.e. biodiversity conservation issues. I have taken part in several projects in this field, mobilizing a variety of approaches at different scales:
- Conservation of aquatic habitats in American deserts (Arizona, USA),
- Cohabitation between wolves and man (DDT and OFB, France), and
- Restoration of endemic ecosystems (Southern Patagonia, Argentina and Amsterdam Island, TAAF - France).
This last project strengthened my interest in ornithology issues, and more particularly in the seabirds of the Southern Ocean, true sentinels of the state of our oceans.
