WebbWe begin by considering the potential benefits and costs of thermoregulation and then focus on a model that maximizes the net energetic benefits. We then expand our focus to include models that also consider nonenergetic benefits and costs. Finally, we shall contemplate the origin and maintenance of endothermic thermoregulation. WebbSupporters of the rules tacitly, or often explicitly, assumed that the clines described by the rules reflected adaptations for thermoregulation. This assumption was challenged by …

WebbBERGMANN'S RULE, ADAPTATION, AND THERMOREGULATION 237 variations that adapted individuals to local environmental conditions (Mayr, 1956, 1963 pp. 60-61, 1965). Bergmann's and Allen's rules exemplified the resulting geographic clines and their adaptive bases.2 Although Mayr sometimes treated the rules as empirical general- WebbThermoregulation can reduce the variance of body temperature (T b) relative to variance of operative environmental temperature (T e.
