The effects of predationrisk in small mammals are mainly include: changes of behavior, activation of the neural circuit and variation of the endocrine.
捕食风险对小型哺乳动物的影响主要包括行为的改变、神经环路的激活和内分泌的变化。

We thus conclude that the aphids have the ability to detect the presence of P. japonica and adopt initiative avoidance responses to reduce the predationrisk.
结论认为，桃蚜可以识别龟纹瓢虫的存在，并对其作出一定的躲避反应，从而降低被捕食的风险。

Starting from natural predation systems, we present a new mechanism involving heterogeneous predationrisk, and develop a new dynamical system model in patchy habitats.
