International audience The ectothermic nature of insects implies that all aspects of their life are shaped by temperature and its variation. As a result, thermal tolerance (the degree of tolerance of an individual to thermal extremes), in parallel with the plasticity of this trait (the capacity to adjust thermal tolerance through acclimatization), are important predictors of the geographic distribution and sensitivity to global warming of organisms (Anderse n et al., 2015; Buckley and Huey, 2016; García-Robledo et al., 2016; Hoffmann et al., 2013). In addition, considering variation in temperature tolerance between populations within sp ecies can be used as an indicator of potential abundance and distribution in response to climate change (Sorte et al., 2011). Indeed, thermal tolerance, and the underlying physiological mechanisms permitting adaptation to temperature changes and extremes, represent important traits un der selection (Angilletta et al., 2002), particularly for range-shifting and invasive species.
