... A. carolinensis , and this difference could be exacerbated by global warming. In the 25 year period addressed in this study, there were few exceptionally hot summers in which operative temperatures in shaded microhabitats exceeded CT max . However, as global temperatures continue to increase, exceptionally hot...

... operative temperature flight temperature Nicrophorus spp. Coleoptera The ability of insects to regulate body temperature and warm the body endogenously has been extensively studied in bees, flies and moths (Heinrich, 1993 , 1996 ). Endothermy was first noted in the Coleoptera in 1945 ( Krogh...

... for the decreased amplitude of daily cycles in T b and the increase in ‘average’ T b with increasing mass. Assessments of ‘average’ daily T b were made by dividing the integral of the difference between measured values of T b and minimum operative temperature by the period of integration, to yield a thermal index...
