概括

野生非洲鼠在自然地下环境中表现出超日活动节奏,而不是日常昼夜节奏. 它们的活动受到每日温度峰值的影响,这表明超日节律在稳定的环境中很常见.

科学领域:

动物行为动物行为
时间生物学时间生物学
哺乳动物生理学哺乳动物生理学

背景情况:

动物使用日常节奏来适应环境条件.
非洲鼠在实验室中被研究为昼夜节律.
野生,地下鼠的昼夜节律仍然不清楚.

研究的目的:

研究野生高原鼠的活动节奏.
确定地下鼠是否表现出昼夜节律.
探索环境因素对活动模式的影响.

主要方法:

用于追踪野生鼠活动的生物记录设备.
在24小时周期内分析活动模式.
活动与环境温度的相关性.

主要成果:

摩尔-老鼠活动显示了超日节律 (4-8小时周期).
个体每天都有多次活动,白天和晚上.
人口活动在下午达到顶峰,与最高温度保持一致.

结论:

拥有稳定的环境的野生地下哺乳动物可能缺乏清晰的昼夜节律.
活动分布在超日周期中,与温度相关.
超日活动节奏可能比以前认为的更为普遍.

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...
