Abstract: During the breeding season, the calling behavior of males is often time consuming and energy consuming. Consequently, males experience a period of caloric restriction due to both the energetic cost of calling and the reduced opportunities for foraging. In addition, the testosterone level of males is increased compared to pre- and post-reproduction. Here, we experimentally induced caloric restriction and increased the testosterone levels of the male European tree frog Hyla arborea to study, in realistic conditions and on the same individuals, mitochondrial activity, which provides the ATP necessary for muscle functioning, trunkmuscle activity and the resulting call. Our results show that the maximal force developed by the trunk muscle was not affected by the caloric restriction, suggesting that frogs were able to maintain force properties, even with half the muscle mass. Furthermore, the caloric restriction and testosterone significantly and positively affected the mitochondrial efficiency of the trunk-muscle fiber. The integrative character of this study allowed for the highlighting of direct relationships between mitochondrial efficiency and trunk-muscle contraction and between trunk-muscle contraction and calling behavior. โข Keywords: Androgen, Tree frog, Trunk muscle, Muscular contraction, Fiber bioenergetics, Acoustic signal
