Offer Description

The project investigates the effects of fluctuating environmental conditions on the demography of animal populations.

Context: Oak trees (Quercus sp.) provide an illustrative case study of the dramatic among-year variation in seed production. The high fluctuation of oak acorn production shapes the dynamics of seed consumers such as birds, rodents, and ungulates, with cascading effects on the entire community. Some organisms adapt to environmental variation by increasing their demographic performance during favorable years, while others maintain a constant demographic performance regardless of resource availability.

Under global warming, the frequency and intensity of acorn production are expected to change, potentially leading to major shifts in the dynamics of seed consumer species and other sympatric species.

Objective: The postdoctoral researcher will:

1. Examine how oak acorn production influences the demographic performance of seed and non-seed consumer species within an intensively-studied temperate oak forest, utilizing long-term individual mark-recapture data on various species including ungulates, birds, and reptiles.
2. Develop a multi-species model to forecast community dynamics under different scenarios of oak production, assessing potential shifts or collapses under climate warming.

The researcher will join the Biométrie et Biologie Evolutive (LBBE) laboratory at LyonTech La Doua in Villeurbanne, supervised by Marlène Gamelon and Jean-Michel Gaillard. Collaboration with the French Office for Biodiversity (OFB) and the Center for Biological Studies (CEBC-Chizé) will be involved.

Additional benefits include a stimulating work environment, professional support, potential teleworking, subsidized meals, partial transport reimbursement, sustainable mobility support, access via public transport, 44 days of vacation/RTT, and health insurance contributions.

Ideal candidates will have:

• A strong interest in statistical modeling
• Experience working with large datasets
• A PhD in ecology with expertise in population dynamics and demography
• Experience analyzing capture-mark-recapture datasets (E-SURGE, RMark, Bayesian approaches)
• Proficiency in R software
• Ability to collaborate effectively both in-person and remotely
• Rigour, good communication, and writing skills
