摘要：

(1) Data from seven populations of klipspringer, a small African antelope, are analysed to determine the extent to which altitude, temperature, rainfall and graze quality influence fecundity. (2) Temperature is the only variable that has a significant effect. (3) It is suggested that, even in the tropics, the energetic cost of maintaining thermoregulation at moderate to high altitudes can be significant and that this leaves the female with less energy to spare for investing in offspring.
