Box 1066 Blindern, N-0316 Oslo, Norway; *e-mail for correspondence: marvidal@udec.cl, marcela.vidal@gmail.com ABSTRACT The interspecific variation of heating rates in Liolaemus lizards, suggests an adaptive value of this physiological thermoregulatory mechanism, which would allow lizards to cope with the environmental thermal restrictions, imposed to behavioral thermoregulation.
This trend has barely been tested at intraspecific level, and here we explore if intraspecific variation in heating rates occurs in Liolaemus tenuis, a relative widely distributed specie...
