Comparison of thermal acclimation effects on the metabolism of Chalcides ocellatus (desert lizard) and Lacerta vivipara (cool-temperate lizard).
The ocellated lizard, Chalcides ocellatus, and the common lizard, Lacerta vivipara, were acclimated to two temperature regimes (10 and 30 degrees C with 12L:12D photoperiod) for 2 weeks. The oxygen consumption rates were measured for both species at temperatures between 5 and 35 degrees C. Cold acclimation was observed in L. vivipara and was in the form of an upward translation of the metabolic rate-temperature curve in comparison to the warm-acclimated lizards (30 degrees C). Chalcides ocellatus showed a response to cold acclimation by decreasing its metabolism only at 10 degrees C.
