... to cold, particularly in Arctic birds. Here, we have studied the potential use of local heterothermy (i.e. tissue cooling that can contribute to significantly lower heat loss rate) in Svalbard ptarmigan ( Lagopus muta hyperborea ) – the world's northernmost land bird. We exposed birds kept under simulated...

We tested this hypothesis at the intraspecific level using male laboratory mice (C57BL/cmdb) fasted under different thermal conditions (20 and 10°C) and for different time periods (12–48 h). We predicted that variability of body temperature ( T b...
