The reproductive activity of males of two species of Ranidella was recorded for four years. Linear densities and vocal activity were monitored, and correlated with rainfall. Energy and ash content of somatic tissue were examined during the course of breeding seasons. Depletions of energy reserves in somatic tissue, fat-bodies and livers were charted through each breeding season. Allometric equations linking these energetic quantities with snout-vent length were used to estimate the growth between breeding seasons of soma, fat-bodies and livers. Males invest heavily in current reproduction and relatively little in growth. Virtually all of a male's reproductive expenditure is directed to mechanisms of intrasexual competition for matings rather than investment in gonads, gametes or parental behavior.
对两种姬蛙属雄性的繁殖活动进行了为期四年的记录。监测了线性密度和发声活动，并将其与降雨量相关联。在繁殖季节期间检查了躯体组织的能量和灰分含量。绘制了每个繁殖季节躯体组织、脂肪体和肝脏中能量储备的消耗情况。使用将这些能量数量与吻肛长度联系起来的异速生长方程来估计躯体、脂肪体和肝脏在繁殖季节之间的生长情况。雄性在当前繁殖上投入巨大，而在生长上投入相对较少。实际上，雄性的所有繁殖支出都用于同性交配竞争机制，而非性腺、配子或亲代行为方面的投入。
