Glycolysis in Anolis carolinensis during agonistic encounters.
We examined the influences of territorial status, encounter outcome, body mass difference, activity, and display on lactate accumulation in adult male Anolis carolinensis during agonistic interactions. Of the pairs of lizards frozen at the onset of an encounter, intruders had significantly higher lactate concentrations than residents. Lactate levels at the onset of an interaction were not significantly different from those at the conclusion, suggesting a limited role for glycolysis during such events. The outcome of an agonistic encounter was not based on fatigue. Individuals that were larger or changed sites had a lower relative lactate concentration at the conclusion of an interaction than smaller or sedentary animals. We consider the influence of autonomic arousal on glycolysis.
