WebThermo-Neutral Zone. The thermo-neutral zone is the range of temperatures between the lower and upper critical temperatures to which an animal may become acclimatized. In new born calves and up to four weeks of age this is between 10⁰C and 25⁰C. Calves at one month it is between 0 degree C and 23 degree C. WebOct 17, 2010 · For polar bears, when temperatures are within the thermal neutral zone of an inactive endothermic animal, its metabolic rate stays stead at resting metabolism, but if the temperature falls below or rises above the thermal neutral zone, an endotherm’s metabolic rate will rapidly increase to two or three times resting metabolism. 2.

The minimum, or basal, metabolic rate (BMR) for a bird usually occurs when it rests at night and it reaches a maximum during flight. Almost all birds have high basal metabolic rates, and passerine birds have rates 50-60% higher than nonpasserines of the same body size. Basal metabolic rate is related to the ...
