Postdoc abisal y genético en Francia


Supervisors : Florence Pradillon & Marjolaine Matabos

Collaborateurs : Didier Jollivet (CNRS/Station biologique de Roscoff) &
Sophie Arnaud (Ifremer, Sčte)

A 12 month post-doctoral fellowship is available in the Ifremer deep-sea
lab (Brest, France) to study the genetic connectivity of several vents
species along the Mid-Atlantic ridge using RADseq genomic approaches.
This project is part of the Abyss Ifremer national project.

There will be a possible opportunity of extension with Dr. Didier
Jollivet at the CNRS/Marine Biological station of Roscoff (in
collaboration with our team) working on bathymodiolin mussels
connectivity at the same sites using similar approaches as part of the
H2020 European project iAtlantic.

TITLE: Demographic history and population connectivity of hydrothermal
vent species along the mid-Atlantic Ridge using a ddRDAseq approach

ABSTRACT: Dispersal and colonization in hydrothermal vent species are
essential to support local populations over short time scales, as well
as in demographic history of species and speciation over longer time
scales. This project is based on the development of genomic scan
approaches (RAD seq and possibly RNA seq) to estimate past and
contemporary connectivity among Mid-Atlantic Ridge vent species. The
shrimps _Rimicaris_ spp., as well as the gastropod species _Peltospira
smaragdina_ and _Lepetodrilus atlanticus_ are major species in animal
communities, especially at vent work sites that have been visited
repeatedly by our laboratory, including those within a mining
exploration license (AIFM) and part of a deep-sea observatory
(EMSO-Azores). We propose to conduct a comparative approach on those
species with contrasting life-history traits in order to 1) describe the
distribution of genetic diversity, to infer past and contemporary
connectivity patterns, and, 2) examine possible links between genetic
connectivity and species life cycle (reproduction and larval life),
geographic barriers, or ecological gradients (depth, chemical signature
of vent fluids). To this end, first an exploratory approach will be
undertaken on different species and one or two will be selected for a
more thorough analysis. This project falls within the scope of the
Ifremer ABYSS project on deep-sea genomics, and will contribute
fundamental data to help define possible strategies to ensure
sustainable human activities in this threatened ecosystem.
