In this project, we plan to study the ability of populations to persist locally under global warming, taking into account not only thermal adaptation but also key biotic interactions that may (directly or indirectly) covary with temperature. We will follow an encompassing approach integrating ecology and evolutionary biology with a special focus on biotic interactions and how plastic and genetic phenotypic responses to a temperature increase feed back on these interactions. To better explore the interplay between temperature, phenotype and biotic interactions and its implications for local population persistence, we will study a set of model groups along a gradient in ecology, generation time and dispersal ability: the cyanobacterium Microcystis, unicellular algae of the genus Eunotia, crustacean zooplankton of the genus Daphnia, and coenagrionid damselflies of the genera Coenagrion and Ischnura.
