The BasicExtinct project integrates leading expertise in paleogenomics and isotope geochemistry to track the combined genetic and behavioral response of megafauna to environmental changes leading to extinction. This research position will primarily focus on Beringian horses during the late Pleistocene, with complementary studies on other megafauna species, such as bisons. Objectives of the project: Build the latest generation of ecological niche-models for horses and bisons in Late Pleistocene Beringia; Contrast individual and population paleogenomics profiles (eg, inbreeding, genetic load and ancestry profiles, demography, genetically-predicted performance and behavioral traits with isotope-based phenotype reconstructions (ie, mobility, diet, habitats, environments, fertility) to determine the combined genotype-phenotype responses to different climate conditions; Correlate demographic trajectories during different climate periods to horse habitat changes, dietary adaptations, fertility rates or mobility habits; Explore sex-specificity of the ecological responses to changing climate conditions.
