摘要: abstract: Zoogeographical effects on the basal metabolic rate (BMR) of 487 mammal species were analyzed using conventional and phylogenetically independent ANCOVA. Minimal BMR variance occurred at a “constrained body mass” 358 g, whereas maximum smallest largest masses. Significant differences in identified for similar‐sized mammals from six terrestrial zoogeographical zones (Afrotropical, Australasian, Indomalayan, Nearctic, Neotropical, Palearctic). Nearctic Palearctic had higher rates than their Afrotropical, Neotropical counterparts. Desert lower mesic mammals. The patterns interpreted with conceptual model describing geographical terms influence latitudinal zonal climate variability. Low high explained unpredictable predictable environments, respectively, especially small large mammal...
