Postdoctoral position in Cayenne – French Guiana (30 months): Dissection of the genetic basis underlying the radiation of warning signals in poison dart frogs

Start date: December 1st, 2022

I am looking to hire a postdoctoral researcher (PDR) to investigate the genetic basis underlying the impressive diversity of vivid color pattern in the Peruvian Ranitomeya poison dart frogs as part of the funded project RANAPOSA. The identification of these genomic regions will enable to test original hypothesis regarding the evolution of mimicry convergence between unrelated species and better understand how warning colorations can diversify so extensively and yet be maintained at very small spatial scale. This study investigates three Müllerian mimetic species, Ranitomeya variabilis, R. imitator and R. fantastica and genetic samples available includes Mendelian crosses, wild individuals from multiple populations with distinct warning colorations, and both genome and transcriptomes are already available.

The PDR will be based in Cayenne (French Guiana at the Laboratoire Ecologie, Evolution, Interaction des Systèmes Amazonien (LEEISA and will be advised by Mathieu CHOUTEAU from the Centre National de la Recherche Scientifique (CNRS). In addition, the PDR will interact with other members of the Ranitomeya consortium: Kyle Summers (East Carolina University), Adam Stuckert (University of Houston) and Rasmus Nielson (UC Berkeley).

Strong expertise in advanced genomic: Association mapping, genome scans, detection of introgression and genomic rearrangements, the use of capture baits, short- and long-reads sequencing, good knowledge of demographic inferences tools, linux system, statistics with R.
Good understanding of molecular laboratory techniques: optimization of DNA extractions, genomic libraries and sequencing design.
Solid organizational and computational skills: curation of the genetic samples, DNA extractions and associated genomic data, handling of genomic datasets generated using different sequencing technologies.
Interest for ecology and evolution: especially in the processes leading to adaptive radiation, including niche specialization, reproductive isolation and population dynamic.
Scientific independence: Excellent analytical and writing skills, good relational abilities and capacity to innovate, interest in developing its own research.

Broader context
French Guiana is an overseas department of France located between Brazil and Surinam. Working in Cayenne provides a privilege access to the living laboratory that is the Amazon but also to an inexhaustible number of outdoor activities. A large international community of ecologists and evolutionary biologists are involved in research projects in French Guiana, and many Research institutes interested by the Amazonian biodiversity are locally present (CNRS, CIRAD, INRAE, IRD, Institut Pasteur, Université de Guyane) providing a stimulating research environment and a unique opportunity to build their academic network. The host institution (LEEISA) is young, dynamics, and working conditions and everyday life are pleasant.

Salary: Wage will follow rules from the Centre National de la Recherche Scientifique (CNRS), and will depend notably on experience. French salaries include social benefits such as health insurance.

Application process: Applicants should apply using the CNRS job portal at the following address:
