Spatially explicit population viability analysis of herbivore populations living in fission-fusion societies

种群生存力分析（PVA）是一种用于预测种群未来规模和灭绝风险的建模工具，通常为管理和保护行动提供信息。虽然群体规模和运动策略对动物的生存和繁殖有很大的影响，但PVA通常不整合社会生态学和运动生态学的原则。这种遗漏可能会降低PVA的准确性，特别是对于生活在聚变裂变社会中的物种。在这样的社会中，群体规模的不断变化直接影响着群体成员的移动、觅食行为以及面临的死亡风险。我们的目标是确定的关键因素造成的空间变化的重要率的群居食草动物，并利用这些信息开发一个空间明确的PVA框架的动物生活在裂变融合的社会。

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.
