INRAE’s Mediterranean Forest Ecology Research Unit (URFM), in collaboration with Aix-Marseille University, is offering two fully funded PhD positions focused on the genetic mechanisms underpinning adaptation in European forest trees. These projects, which address critical questions about resilience to climate change, will explore both the adaptive genetic variation within populations and the genetic basis of key phenological traits in common beech (Fagus sylvatica) and sessile oak (Quercus petraea).
PhD position 1: Adaptive genetic variation and climate vulnerability in beech forests
This project investigates how standing genetic variation and local adaptation influence the vulnerability of Fagus sylvatica to ongoing climate change. The candidate will assess intraspecific trait variation across the species range, quantify environmental effects on genetic diversity within populations, and model growth-resistance trade-offs and potential maladaptation.
Using data from extensive provenance trials and a common garden experiment, the student will integrate genomic, phenotypic, and environmental data through statistical and mechanistic modelling.
PhD position 2: Genetic bases of leaf and reproductive phenology in oak and beech
Focusing on two essential processes (growth and reproduction) this PhD will explore how their timing (phenology) is genetically controlled and contributes to long-term adaptation. The research will examine traits such as leaf emergence and masting, aiming to uncover their genetic architecture and how they may evolve under climate change.
The student will collect phenotypic and environmental data, perform genome-wide association studies (GWAS), estimate breeding values (BLUP), and use forward simulation models to forecast adaptive trajectories under different climate scenarios.
Shared environment and supervision
Both PhD candidates will join the ‘BioPopEvol’ team at INRAE Avignon, working under the supervision of Dr Julie Gaüzère and Dr Ivan Scotti. They will benefit from a collaborative research network involving evolutionary biologists, tree ecologists, and ecological modellers, as well as access to rich genomic datasets and field sites.
Candidate profile
Applicants for both positions should hold a Master’s degree in evolutionary biology or a related field, have experience with statistical analysis (preferably in R), and demonstrate a strong interest in ecological genomics and forest adaptation. Proficiency in English and strong writing skills are essential.
