Description of the thesis topic
This thesis project aims to better understand the recruitment of juveniles of coral reef fishes in their final habitat and will use the anemonefish as model systems. The PhD student will carry out ecological approaches in the field, combined with laboratory analyzes to characterize how the environment influences the physiological and neuroendocrine status of juveniles and their quality in their natural habitat. For this we will exploit natural situations in Okinawa and in French Polynesia where juvenile clownfish are found in different ecological contexts, and we will follow how they adapt to these contexts. We will also use mesocosms to reproduce the environments observed in the wild and to further characterize the mechanisms at play. In addition to analyze larval recruitment (a fundamental step that allows the renewal of reef fish populations), this work will allow to better understand the bases of local adaptation, a particularly important phenomenon in the context of global warming.
The PhD student will join the Eco-Evo-Devo team (Dr L. Besseau), in the UMR BIOM, (Integrative Biology of Marine Organisms) at the Oceanological Observatory of Banyuls sur mer, which has all the infrastructure and technical platforms necessary for this work. Field observations and sampling of juvenile clownfish will be carried out during field trips in Moorea, French Polynesia and Okinawa (Japan) in the teams respectively of UMR CRIOBE (Dr D. Lecchini - Center for Insular Research and Observatory of the Environment) and the MEEDU group (Dr V. Laudet - Marine Eco-Evo-Devo Unit) at OIST (Japan).)
