对四种热带蛙的捕食偏好进行了代谢相关性评价。蚂蚁和白蚁的捕食与高有氧能力、低无氧能力和高静息代谢相关。相反，依赖更大、更灵活的猎物，如直翅类和鞘翅类，与低有氧能力、高无氧能力和低静息代谢有关。这些相关性可能源于不同觅食行为的代谢需求。捕食者和猎物的特征相互作用产生了这些需求，从而产生了一系列的觅食模式。运动、竞争行为和生殖特征也与代谢能力密切相关。食肉动物的运动生理学反映了这种情况的复杂性。
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.
