A passion for the observation of wildlife led me to the study of behavioural ecology to grasp the drivers of the evolution of behaviours. Currently in my first year of a master’s degree in behavioural ecology in France, it is in this context that I joined the WEEL team for a 3-month internship. My research is focused on the seasonal variations of sociality among caribou in relation to the distribution of resources and the attraction of conspecifics.
