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.
