Lay summary
For million years, periodic climatic oscillations have been a fundamental factor shaping the biogeographic history and genetic structure of species. Major climatic changes have driven migration of populations to follow the shift of their suitable habitats and have restructured the gene pools of species, producing the genetic and species diversity found today. In areas such as the western Palearctic, physical barriers (i.e. the Mediterranean Sea) impede migration to warmer places during cold periods, and confine species to a few restricted refugia. Based on fossil and genetic evidence, several studies have examined the potential refugia and described major paradigm patterns of postglacial recolonization routes in several European species. However, it can be expected that climatic oscillations also strongly influence ecological interactions and species coevolution. From one glacial cycle to another, the species composition of European refugia should differ, according to the ability of populations to reach suitable places, but also due to many stochastic processes in their population dynamics. Therefore, evolution of specific interactions between European taxa is threatened during every glacial cycle and emerging coevolutionary processes could stop brutally. If one species strongly depends on another, its history is completely linked to that of its partner. After addressing the biogeographic histories of single species, the next step is therefore to understand how glaciations cycles modify the pattern of specific interactions among such species. In this project, we aim to compare postglacial colonization routes and refugia in pairs of interacting European species of insects and plants. Depending on the nature of the interaction (antagonism vs. mutualism), several patterns can be expected. Using DNA markers, we will assess phylogeographies of six pairs of interacting plants and insects in Europe (two mutualisms and four antagonisms). By comparing phylogeographic patterns, we will determine the congruence/incongruence of biogeographic histories of interacting species and relate this to the type of interaction (mutualism vs. antagonism). This will provide an understanding of where and when specific interactions were produced and maintained through major climate changes, and reveal whether their communities survive climatic change or are recreated afterwards.
