  • Title: Aerobic and anaerobic metabolism of paired male lizards (Anolis carolinensis).
    Author: Wilson MA, Gatten RE.
    Journal: Physiol Behav; 1989 Dec; 46(6):977-82. PubMed ID: 2634263.
    Abstract:
    The associations of physical activity, skin color, body mass difference and conspecific olfactory cues with short-term aerobic and anaerobic metabolism in paired male Anolis carolinesis were examined. Control measurements for mild laboratory manipulation (such as the movement of a metabolic chamber) yielded significant increases in the rate of oxygen consumption, but not in the lactate concentration of these animals; stronger manipulation increased both. A possible influence of conspecific olfactory cues on the metabolism of lizards introduced into empty chambers was undetected. Anolis that turned from green to brown with handling showed an increase in oxygen uptake, but an association between this color shift and total body lactate level was not detected. Elevated rates of oxygen use and glycolysis were found in pairs of males in the absence of physical activity. Lactate levels of the individuals of a pair were positively correlated with one another; the lactate concentrations of lizards placed into occupied metabolic chambers were correlated with the difference in body mass of the pair.
