Population viability analysis (PVA) is a modelling tool used to predict the future size and extinction risk of populations, and commonly informs management and conservation actions. Although group size and movement tactics can have a strong impact on animal survival and reproduction, PVAs generally do not integrate principles of socioecology and movement ecology. The omission could reduce the accuracy of PVAs, especially for species living in fusion-fission societies. In such societies, the constant changes in group size directly influence the movement of group members, their foraging behaviour, and the mortality risk they face. Our objectives are to identify the key factors causing spatial variation in vital rates of gregarious herbivores, and use this information to develop a spatially explicit PVA framework for animals living in fission-fusion societies.

种群生存力分析 (PVA) 是一种建模工具，用于预测种群未来的规模和灭绝风险，通常为管理和保护行动提供信息。尽管群体规模和运动策略会对动物的生存和繁殖产生重大影响，但 PVA 通常没有整合社会生态学和运动生态学的原理。这一遗漏可能会降低 PVA 的准确性，特别是对于生活在聚变裂变社会中的物种而言。在这样的社会中，群体规模的不断变化直接影响群体成员的行动、觅食行为以及他们面临的死亡风险。我们的目标是确定导致群居食草动物生命率空间变化的关键因素，并利用这些信息为生活在裂变融合社会中的动物开发一个空间明确的 PVA 框架。
