The interdisciplinary approach adopted in my research activities aims to combine: (i) follow-up in situ the spatio-temporal dynamics of communities in response to environmental conditions, (ii) laboratory experiments on functional paths and thermal tolerance individuals (breathing, predation, etc.), (iii) anticipatory prediction models current and future favourable ecological niches and (iv) larval connectivity models between populations. These methodological approaches are coupled with integrative approaches linking human and social sciences and functional ecology in order to understand the issues at stake in the socio-ecosystems under study, in relation to the various social stakeholders. This interdisciplinary approach is conducted mainly on ectothermic species, with a particular focus on transitional ecosystems such as wetlands and lagoon and coastal communities.
