Abstract

The circadian behavior of the desert iguana, Dipsosaurus dorsalis, was investigated on the basis of behavioral observation and electrophysiological recording. D. dorsalis adequately complies with accepted criteria for both behavioral sleep and paradoxical sleep. At 20 degrees C, 12% of the photophase is spent in sleep, 95% of the scotophase is spent in sleep. Paradoxical sleep occurs at all times of the year, but only at temperatures of 20 and 30 degrees C. Amounts of behavioral sleep are affected by both temperature and time of year. Total sleep increases with decreased day length and decreased temperature. Daytime sleep increases with decreased temperature.

摘要

基于行为观察和电生理记录，对沙漠鬣蜥（Dipsosaurus dorsalis）的昼夜行为进行了研究。沙漠鬣蜥完全符合行为睡眠和异相睡眠的公认标准。在20摄氏度时，光照期的12%用于睡眠，暗期的95%用于睡眠。异相睡眠在一年中的任何时候都会出现，但只在20摄氏度和30摄氏度的温度下出现。行为睡眠量受温度和一年中的时间影响。总睡眠时间随着白昼长度的缩短和温度的降低而增加。白天睡眠时间随着温度的降低而增加。
