While direct influences of the environment on population growth and resilience are well studied, indirect routes linking environmental changes to population consequences are less explored. We suggest that social behavior is key for understanding how anthropogenic environmental changes affect the resilience of animal populations. Social structures of animal groups are evolved and emergent phenotypes that often have demographic consequences for group members. Importantly, environmental drivers may directly influence the consequences of social structure or indirectly influence them through modifications to social interactions, group composition, or group size. We have developed a framework to study these demographic consequences. Estimating the strength of direct and indirect pathways will give us tools to understand, and potentially manage, the effect of human-induced rapid environmental changes.
虽然环境对人口增长和弹性的直接影响已经得到了很好的研究,但将环境变化与人口后果联系起来的间接途径却研究得较少。我们认为,社会行为是理解人为环境变化如何影响动物种群弹性的关键。动物群体的社会结构是进化和涌现的表型,它们通常对群体成员具有人口统计学上的后果。重要的是,环境驱动因素可能直接影响社会结构的后果,也可能通过对社会互动、群体组成或群体大小的改变间接地影响社会结构的后果。我们已经开发了一个框架来研究这些人口统计学后果。估计直接和间接途径的强度将为我们提供工具,以理解和潜在地管理人类引起的快速环境变化的影响。
