Abstract

Metabolic correlates of prey preference were evaluated in four species of tropical frogs. Predation on ants and termites is correlated with high aerobic capacity, low anaerobic capacity, and high resting metabolism. In contrast, dependence on larger, more mobile prey such as orthopterans and coleopterans is associated with low aerobic capacity, high anaerobic capacity, and low resting metabolism. These correlations presumably stem from the metabolic demands of different foraging behaviors. Characteristics of both the predator and the prey interact to create these demands, thereby producing a spectrum of foraging modes. Locomotion, agonistic behavior, and reproductive characteristics also can be intimately associated with metabolic capacities. The exercise physiology of predators reflects the complexity of this situation.
