动物学动物学
时间生物学时间生物学
动物生理学动物生理学

背景情况:

动物面临着环境温度波动.
在寒冷时期,Poikilothermic物种进入化.
化过程中的生理反应尚不清楚.

研究的目的:

在冷却和回暖过程中检查胡须龙的行为反应.

主要方法:

胡子龙 (Pogona vitticeps) 在30°C的恒定光线下进行了研究.
对运动机动活动进行了监测.
动物被暴露在低温 (4°C) 中以诱导化.

主要成果:

恒定的光线诱导了自由运行的节奏.
低温暴露 (4°C) 停止了运动.
重温显示昼夜节律的恢复取决于冷却停止的时间.

结论:

循环节律在化后重置受到冷却停止的影响.
冷却的阶段或持续时间并不决定后节律的恢复.
这突显了爬行动物季节性适应的一个关键因素.

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...
