Who are we?
PhD-candidate Aurelien Grange (GINR)
Aurel is investigating how caribou physiology, movement, and genetics links to local adaptation within a single management unit. First, he will identify different physiological strategies supporting pregnancy using morphological measurements, diet composition, and stable isotope analyses, in order to test the existence of distinct caribou phenotypes within a same management unit. Second, he will analyze GPS data from collared females to assess how vegetation, terrain, and human activities influence seasonal movements to further quantify landscape friction and its role in gene flow. Third, Aurel will combines movement and genomic data to investigate fine-scale population structure and functional landscape connectivity. Genomic analyses will also explore candidate genes linked to physiological differences, informing whether caribou show local adaptation or strong physiological plasticity, with direct implications for conservation and management under climate change.

PhD-candidate Laura Barbero-Palacios (GINR)
Laura is an arctic ecologist interested in the effect of herbivores on tundra ecosystems. Her research focuses on plant-herbivore interactions at a landscape scale, as well as population dynamics and habitat use. She is also interested in the role herbivores play in nutrient cycling and in trophic rewilding. Additionally, she is a talented scientific illustrator!

PhD-candidate Maud Therrien (Guelph University)
Supervision: John Fryxell (Guelph University), Larissa Beumer (UNIS), Mathilde Le Moullec (GINR).
MSc-student Amelia Keilbach (GINR, Umeå University)
Amelia is using telemetry and field data to investigate the landscape characteristics of calving and post-calving areas used by caribou in the Kangerlussuaq-Sisimiut management area.
Supervision: Mathilde Le Moullec (GINR), Gesche Blume-Werry (UMU)
Research Assistant Arthur Grand
Arthur is working on a vegetation map for the Kangerlussuaq-Sisimiut management area, as well as investigating how winter icing events affect plants' nutrient content.
