Abstract(s) :

(Anglais) Climate change has been recently pointed out as one of the major causes of extinction in several species [2]. Climate change is related to an increase of frequency of extreme event such as heat waves [3]. Bumblebees are robust and hairy bees with hetero-endotherm metabolism [4]. They are able to live in the highest-elevation and northern ecosystems which are also the hardest regions hit by climate change [5]. Here, we establish a comparative circum-polar map of hyperthermic resistance of bumblebees with a new portable experimental device. We follow a continental and latitudinal gradient to predict consequences of heat waves on the pollinator fauna in arcto-alpine regions and to identify the potential refuge zones around the Arctic Circle.
