Postdoc position: Eco-evolutionary feedback loops in wild brown trout - Laboratories: DECOD, Rennes, France. EGCE, Saclay, France. CEES, University of Oslo, Norway. BioSP, Avignon, France. - Project description: We are looking for candidates who are willing to apply on the ECODIV-INRAE call for postdoctoral fellowships. This call targets early-career scientists (from PhD students to < 3 years postdocs) to help them transition towards permanent research positions at INRAE. If successful, candidates will be granted a 12 to 24-month full-time postdoc position at INRAE. Application is in the form of a 5-page postdoc project co-constructed with the postdoc candidate. Our group proposes a project coupling mark-recapture and quantitative-genetic animal models to explore eco-evolutionary feedback loops acting on body size in fish. The project uses data collected on stream-resident brown trout native to a small natural stream (Bellbekken) in Norway. This fish population was the object of a long-term mark-recapture monitoring programme that included individual phenotyping and parentage assignment. Specifically, mark-recapture data are available for > 12000 fish from 1997 to 2009, including tag id, body size, sex if possible, and age (not complete), and genotyping data are available for > 3300 offspring genotypes and > 560 parent genotypes from 2002 to 2007. Previous studies have shown that heritability for length at age ranges from 0.16 to 0.31 in Bellbekken trout, that somatic growth and survival are negatively density- and size-dependent, and that sexual selection favours larger-bodied individuals. These previous studies suggest that trout body size, and possibly other traits such as dispersal propensity, might be subject to eco-evolutionary feedback loops involving natural and sexual selection. - Information and contact: If you are interested in this project and proficient in programming and statistical modelling, please send an E-mail with your CV to: Eric Edeline: eric.edeline@inrae.fr Arnaud Le Rouzic: arnaud.le-rouzic@universite-paris-saclay.fr Leif Asbjørn Vøllestad: l.a.vollestad@ibv.uio.no Julien Papaïx: julien.papaix@inrae.fr. - Timeline: Application deadline is in July 2024. We will organize interviews until mid June, so as to let us enough time to co-write the application with the successful candidate.
