Predation risk as a cost of reproduction in animals has recently received increased empirical and theoretical attention. Higher risk may be associated with all stages of reproduction. Examples of evolutionary responses to this increased risk include habitat choice, duration and timing of display and copulation, changes in brightness of breeding coloration, and changes in life history traits such as age of reproduction and reproductive effort.
捕食风险作为动物繁殖的一种成本，最近受到了越来越多的实证和理论关注。更高的风险可能与繁殖的所有阶段都有关。对这种增加的风险的进化反应的例子包括栖息地选择、展示和交配的持续时间和时间、繁殖颜色亮度的变化，以及繁殖年龄和繁殖努力等生活史特征的变化。
