PostDoc position at IMBE Station marine d’Endoume on “Marine comparative population genetics and community ecology”

 

We seek candidates who proved their autonomy in data analyses and in writing international scientific papers. A solid experience in population genetics is also required. Expertise in community ecology, benthic coastal marine biodiversity, marine currentology, modelisation, as well as scuba-diving is not compulsory but considered as a “plus”. Our goal (IMBE) in this DEVOTES program is to evaluate the interest and the limits of intra-specific genetic diversity (of a set of species) as an indicator of the good environment status of a locality. For this, we compare local diversity among species, with species diversity (Shannon or other indices) when possible, and we aim at correcting for (or taking into account) genetic connectivity and physical connectivity.

The post-doc will at first benefit from an already available data set (partly published) of population genetic data from 6-10 invertebrate species (eventually a red alga may also be available) with contrasted dispersal abilities in a common set of localities along the French Mediterranean coast. His first goal will be to combine those data in a global analysis, integrating physical data and models (by collaborations with physical oceanographers), biological data on life history traits  (duration and season of dispersal stage), and disentangle factors linked to physics, life history traits. The post-doc is expected to write and submit one scientific article (at least) within the 6 months period with the data that were already available.

The fellowship of 18 months, financed by DEVOTES, will then be proposed for a combined study comparing community composition and intra-species genetic diversity, focusing on coralligenous habitats. Coralligenous habitats are typically Mediterranean; they are highly complex habitats, based on a biogenic substratum composed of a variety of red algae. Community composition will be obtained from metabarcoding (with controls by classical taxonomy and photo-quadrats). Population genetics will be studied for a few species of the coralligenous habitat: at least one red alga (or a full species complex, providing natural replicates), a bryozoan, etc. (NGS genotyping will be obtained for some species). Samplings are finely contextualized by contrasted ecological parameters (orientation, depths, slope, rugosity, temperature…) within each locality (islets), allowing estimating the relative parts of adaptation and neutrality at both the intra-specific and the community levels (local adaptation, neutral theory of biodiversity). This sampling and ecological study is a strong part of the European ANR “CIGESMED” (an ERANET project of the Seas-ERA call).
