Higher average ambient temperatures are also worth considering because they would tend to blur the concepts of endo- versus ectothermy: with high ambient temperatures, homoiothermy can be achieved in large, compact animals with a low metabolic rate ( Spotila et al., 1991 ), whereas tachymetabolic species face overheating in the absence of effective physiological or behavioural cooling mechanisms.
