Data are presented on metabolic rates and thermal conductance for four species of neotropical bats, Pteronotus quadridens, Mormoops blainvillii (Mormoopidae), Monophyllus redmani and Erophylla bombifrons (Phyllostomidae). Each of these bats predominantly or exclusively roosts in hot caves (28-40 degrees C) in Puerto Rico. Basal metabolic rates (BMR) for these four species were 55%, 48%, 66%, and 66% of values expected from the Kleiber curve, respectively. Thermal conductance was 93%, 55%, 175%, and 158% of values expected from the Aschoff curve, respectively. These data indicate that, in addition to food habits, variation in BMR is highly correlated to roost microclimate. Pteronotus and Mormoops, like other insectivorous species, have low BMRs. The low BMR of the nectar/fruit eating Monophyllus and Erophylla, as well as the low termal conductance in Mormoops, is consistent with their habit of roosting in hot caves, suggesting that roost microclimate is an important selective force in the physiological adaptation of these bats.
本文展示了四种新热带蝙蝠的代谢率和热传导数据，这四种蝙蝠分别是四齿无尾蝠（Pteronotus quadridens）、布氏妖面蝠（Mormoops blainvillii，妖面蝠科）、红曼氏叶鼻蝠（Monophyllus redmani）和黄胸叶鼻蝠（Erophylla bombifrons，叶口蝠科）。这些蝙蝠每一种都主要或完全栖息在波多黎各炎热的洞穴中（28 - 40摄氏度）。这四个物种的基础代谢率（BMR）分别为克莱伯曲线预期值的55%、48%、66%和66%。热传导分别为阿绍夫曲线预期值的93%、55%、175%和158%。这些数据表明，除了饮食习惯外，基础代谢率的变化与栖息微气候高度相关。四齿无尾蝠和妖面蝠与其他食虫物种一样，基础代谢率较低。食花蜜/果实的红曼氏叶鼻蝠和黄胸叶鼻蝠的低基础代谢率，以及妖面蝠的低热传导，与它们栖息在炎热洞穴的习性一致，这表明栖息微气候是这些蝙蝠生理适应过程中的一个重要选择因素。
