- ... Paradoxically, some insects have an increased capacity to survive higher temperatures in winter than summer. Possible contributors to this increased heat tolerance in winter could be their sub-zero adaptations (high polyol concentrations, antifreeze proteins, antifreeze glycolipids, etc.). To investigate if a sub-zero adaptation can increase organismal high temperature survivorship, we tested tran ...

- ... In the face of global warming, both the absolute thermal tolerance of an ectotherm, and its ability to shift its tolerance level via acclimation, are thought to be fundamentally important. Understanding the links between tolerance and its plasticity is therefore critical to accurately predict vulnerability to warming. Previous studies in a number of ectotherm taxa suggest trade-offs in the evoluti ...
