Webphase thermoneutral zone is a thermoneutral point (TNP), deﬁned as a discrete ambient temperature below which energy expenditure increases and above which body temperature increases. The mouse TNP changes diurnally by 4 C. Thus, studying mice strictly ‘‘at thermoneutrality’’ is not feasible. Skop et al., 2024, Cell Reports 31, 107501 ...

WebFor an endotherm, the BMR is also measured when the animal is in a thermoneutral environment, that is, one where the organism does not expend extra energy (above baseline) to maintain temperature. For an ectotherm, SMR will vary with temperature, so any SMR measurement is specific to the temperature at which it's taken.
