本文研究了能量限制对雄性欧洲树蛙繁殖行为的影响，以及鸣叫雄性树蛙如何分配通过摄食实验提供的额外能量。在合唱队中存在的能量消耗表明，喂食和未喂食的雄性体重都在下降。提供额外能量的雄性没有表现出更长的合唱时间。相反，吃饱了的雄企鹅会更快地回到合唱队。此外，喂食的雄性比对照组的雄性更频繁地打电话，这对无尾猿来说是一种新的反应。补食31夜后，雄蝶的鸣叫率显著提高。这种分配额外能量储备以提高呼叫率的策略是有益的，因为雌性杂交种偏爱高呼叫率的雄性，而且雌性有能力探测到呼叫率的小幅增加。
We investigated the effects of energetic constraints on the breeding behaviour of male European treefrogs Hyla arborea and how calling males allocated additional energy supplied by feeding experiments. Presence in the chorus was energetically costly indicated by both fed and unfed males losing weight. Males that were supplied with additional energy did not show longer chorus tenure. Instead, fed males returned sooner to the chorus. Additionally, fed males called more often than control males, a novel response for anurans. A significantly higher calling rate was noted from males even 31 nights after supplementary feeding. This strategy of allocating additional energy reserves to increasing calling rate is beneficial given the preference of female hylids for males calling at high rates and a female's ability to detect small incremental increases in calling rate.
