This study examined how the standard metabolic rate of tegu lizards, a species that undergoes large ontogenetic changes in body weight with associated changes in life‐history traits, is affected by changes in body mass, body temperature, season, and life‐history traits. We measured rates of oxygen consumption (V̇o2) in 90 individuals ranging in body mass from 10.4 g to 3.75 kg at three experimental temperatures (17°, 25°, and 30°C) over the four seasons. We found that standard metabolic rate…

MR increases significantly with increasing temperature for both total and mass-specific MR, and a 40 g lizard requires the equivalent of two to three mealworms per day to cover the costs of maintenance metabolism.

Tegu lizards reduced their metabolism to the low rates seen in winter dormancy at all times of the year when given sufficient time in the cold and dark, suggesting that the temperature‐independent reduction of metabolism was already in place by autumn before the tegus had enteredWinter dormancy.

There was a continuous decline in nighttime breathing and heart rate, at constant Tb, throughout the late summer and fall suggestive of an active metabolic suppression that developed progressively at night preceding the entrance into dormancy.

The results reveal that incubating eggs at temperatures ranging from 24—30 ℃ does not have important effects on embryonic metabolism and hatchlings behavior in D.rufozonatum, and this result better explains why hatchlings incubated at lower temperatures are larger in snout-vent length and heavier than those incubation at higher temperatures.

The functional significance of panting as a mechanism of thermoregulation and its relationship to the critical thermal maxima in lizards
- Environmental ScienceJournal of Experimental Biology

It is found that many lizard species can depress body temperature below air temperature via panting and evaporative cooling, and the capacity to do so appears to be a function of each species' ecology and thermal environment, rather than phylogeny.

It is predicted that as Tb increases, so must prey consumption to meet annual SMR energy demands, and Tb variation likely affects patterns of energy acquisition and use and, in turn, influences processes such as growth and reproduction.

The concomitant shift in the V̇O2 mass exponent in early autumn and during winter dormancy indicates an allometric effect on the degree of metabolic depression related to the size of the fat stores and suggests greater energy conservation in the smaller young.

Low standard metabolic rates in this species are probably an adaptation to herbivory in hot desert environments, and increased as temperature increased with high Q 10 values at low temperatures.

It seems that low thermal sensitivity for summer–acclimatized group may facilitate activity during its active seasons, and high thermal sensitivity between 20 and 25°C for winter–ac Climatization group may conserve energy during inactivity in winter.

A general model is derived, based on principles of biochemical kinetics and allometry, that characterizes the effects of temperature and body mass on metabolic rate of microbes, ectotherms, endotherms (including those in hibernation), and plants in temperatures ranging from 0° to 40°C.

Estimating the metabolic rates of juvenile squamates from equations based on comparisons among species is invalid because there is significant variability among mass exponents among the 14 species that met the statistical requirements for analysis of covariance, and a common mass exponent cannot be assumed for intraspecific comparisons.
