Data for: Latitudinal cline of death-feigning behaviour in a beetle (Tribolium castaneum)

Death-feigning behaviour is a phenomenon in which a prey is rendered motionless due to stimulation or threat from a predator. This anti-predator defense mechanism has been observed across numerous animal taxa and is considered adaptive in nature. However, longer durations of death feigning can result in decreased opportunities for feeding and reproduction, and therefore is often associated with higher fitness costs as compared to environments without predators. Differences have also been observed in the frequencies and durations of death-feigning behaviours within animal populations, and these differences are thought to be influenced by the balance between survival and other fitness costs. Furthermore, this balance is predicted to vary in response to changes in environmental conditions. In this study, we examined the frequency and duration of death-feigning behaviours in 38 populations of the red flour beetle (Tribolium castaneum). Our results demonstrate that frequencies and durations ..., ,

假死行为（death-feigning behaviour）是指猎物因捕食者的刺激或威胁而陷入静止状态的现象。该反捕食防御机制已在众多动物类群中被观测到，且被认为具有自然适应性。然而，更长时长的假死行为会减少觅食与繁殖机会，因此相较于无捕食者的环境，这类行为往往伴随着更高的适合度代价。在动物种群内部，假死行为的发生频率与持续时长也存在差异，这类差异被认为受生存与其他适合度代价之间的平衡所影响。此外，该平衡预期会随环境条件的变化而发生改变。本研究针对38个种群的赤拟谷盗（Tribolium castaneum）的假死行为发生频率与持续时长展开了观测分析。本研究结果表明，假死行为的发生频率与持续时长……
