Abstract: Some numerical indices , namely θ, λ,Φ and η, are proposed to evaluate the daily activity patterns of rodent. The value of θ is used to determine whether there is any discrepancy in the daily activity patterns of animal ; the value of λ is used to judge whether an animal is diurnal or nocturnal ; the index Φ is used to identify which activity patterns (single-peak or double-peak) the animal is ; andηindicates the absolute active rate of the animal. Such numerical indices may provide different features of activity patterns of animal and should be useful in activity patterns comparing analysis.

摘要: 提出评估啮齿动物活动模式的4 种定量指标: θ、λ、Φ和η。θ主要衡量动物日活动强度的差异程度; λ用于判断动物活动究竟是以昼行性为主还是以夜行性为主; Φ用来甄别动物的活动究竟接近于(或者属于) 单峰型还是接近于(或属于) 双峰型; 而η则是度量动物绝对活动强度的指标。这4 种数值指标分别从不同角度阐明动物活动模式的特征, 可为分析比较动物的活动模式提供参考依据。
