...Sasha Ayton; Sean Tomlinson; Ryan D. Phillips; Kingsley W. Dixon; Philip C. Withers ABSTRACT Seasonal acclimatisation of thermal tolerance, evaporative water loss and metabolic rate, along with regulation of the hive environment, are key ways whereby hive-based social insects mediate climatic...

... evaporative cooling capacity ( N =10 per site per season); the maximum T a birds tolerated before the onset of severe hyperthermia ( T b ≈44°C) was considered to be their hyperthermia threshold T a ( T a,HT ). Our data reveal significant seasonal acclimatisation of heat tolerance, with a desert population...

... seasonal fluctuations in body temperature will show seasonal acclimatisation in the activity of its metabolic enzymes. We measured body temperatures of alligators in the wild in winter and summer ( N =7 alligators in each season), and we collected muscle samples from wild alligators ( N =31 in each season...

... by following muscle recruitment patterns using electromyography. The mean (± S.E.M.) speeds recorded for maximal sustainable aerobic exercise were 0.52±0.02, 0.81±0.06 and 0.39±0.02 BL s −1 (body lengths per second) for animals swimming at their acclimatisation temperatures of 4, 11 and 18 °C, respectively...
