Webb17 nov. 2009 · The “comfort zone” where animals can reach their BMR without enhanced water loss is known as the thermoneutral zone (TNZ) (10). It is the capacity to be within … WebbWarming ingested prey will exacerbate the challenge of maintaining thermal balance in cold water, particularly for endotherms feeding on cold ectothermic prey (Wilson et al., 1992a; Hedd et al., 1996). The cardiovascular system is integral to the physiological responses associated with the dive response, exercise, digestion, and thermoregulation.
Webb27 maj 2024 · Ectotherms have developed several behavioral thermoregulation mechanisms, such as basking in the sun to increase body temperature or seeking shade … WebbMechanisms of thermoregulation. As a refresher, animals can be divided into endotherms and ectotherms based on their temperature regulation. Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat ...
