- Abstract
Macrophysiological analyses are useful to predict current and future range limits and improve our understanding of endotherm macroecology, but such analyses too often rely on oversimplifications of endothermic thermoregulatory and energetic physiology, which lessens their applicability. This idea essentially requires that heat balance in endotherms follows Newton's laws of cooling, which may be a reasonable simplification in a small number of homeothermic species (usually mammals, but not birds), but is clearly not universal (King, [16]; McNab, [22]). However, this model requires that (a) thermal conductance below the TNZ is constant, (b) that endotherms maintain a relatively constant I T i SB b sb , and (c) that I T i SB lc sb can be estimated at a single value. Importantly, authors of several of the original papers commented that either I T i SB b sb or I T i SB lc sb was difficult or impossible to establish for several of these species (e.g., I Arctictis binturong i , McNab, [25]).
