How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
CNRS Reseacher at the CEBC-CNRS, France. I study how ectotherms face spatial and temporal variations in their environment. The anthropocene imposes unprecedented constraints and species responses will depend on their physiological and behavioral capacities. Reptiles and amphibians are particularly vulnerable and provide excellent models for addressing these effects. My research combines three main axis: (1) Climate adaptations, (2) Parental influences (3) Habitats quality and conservation

We are studying the impact of climate and habitat changes on a squamate community in Loire Atlantique. This work focuses mainly on 5 sympatric snakes species with contrasted ecology.
Clarifying the impact of climate changes on ectotherms in the Nouvelle Aquitaine region. This project is carried by Cistude Nature https://www.sentinelles-climat.org
The aim of this project is to identify the mechanisms that affect the population dynamics of the European Pond Turtles living on the Tour du Valat estate. We are particularly interested in measuring and monitoring the values of key demographic parameters such as age, sex ratio, survival, dispersal, growth, and age at time of first reproduction, as well as the effects of climate change (management techniques, climate, and water quality) on this aquatic turtle species that is threatened in France, and for which the Camargue is a major site. This project is based on a long-term study that was begun in 1997 by Elisabeth Rosecchi, prior to which several dozen European Pond Turtles had been marked by Alan Johnson as of 1976. Every year a capture-mark-recapture (CMR) campaign takes place from April to August on the Tour du Valat estate. The turtles are captured with fyke nets, and are individually marked by incisions on outer plates of their carapace (scutes). By the end of 2017, nearly 1200 turtles had been marked at the Tour du Valat in the course of 9500 captures.
