Marguerite Duchesne; Sarah Senécal; Audrey Le Pogam; François Vézina - Abstract: Given that several species of non-migratory forest birds only moult in the fall, it is possible that individuals with better insulation have an advantage in terms of thermoregulation in winter, but are limited during the breeding season....
Hourcade Felipe; Turcotte M; Alfaro M; Vézina F; Clavijo-Baquet S - Abstract: Reproduction is considered one of the most energy demanding life history stages in birds, particularly during nestling provisioning in altricial species. At this stage birds are often working at their maximal sustainable rate to feed their offspring and are unable to further increase their parental effort. The heat...
Anand, Sachin; Le Pogam, Audrey; O'Connor, Ryan; Love, Oliver; Vézina, François - Abstract: The Arctic is warming nearly four times faster than the rest of the world, posing a serious threat for cold-adapted species living here. Species such as the snow buntings, a small Arctic breeding passerine, exhibit high cold endurance but poor tolerance to even moderately warm temperatures. Understand...
De Bonville, Jérémy; Raby, Graham - Abstract: In freshwater ecosystems, increasingly frequent heatwaves threaten the physiological performance, behaviour, and survival of ectotherms such as fish. The ability of fish to acclimate to fluctuating temperatures and the metrics used to quantify it are central to predicting resilience and guiding conservation efforts. The critical thermal maximum (...
