项目摘要

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. We will study free-ranging plains bison in and around Prince Albert National Park. This bison population faces wolf predation, as well as hunting outside of the park. We will conduct field studies to characterize the spatio-temporal patterns in age-specific vital rates, and identify the environmental factors responsible for those patterns. Field work will involve the extensive use of radio-telemetry. Traditional GPS collars will characterize the spatial dynamics of bison and wolves, whereas proximity collars will provide a detailed account of each interaction between collared bison and wolves. A number of bison will be fit with GPS-collars equipped with a video camera. The footage will provide a broad range of information such as food choice, duration of resting and forging bouts, and calf mortality. Concurrently, we will conduct field surveys to determine group size, vegetation quality, and the activity budget of non-collared bison. We will also collect biological samples for hormonal and DNA analysis. Overall, the field data will be used to 1) develop movement models for individuals living in fusion-fission societies established in patchy environments, 2) link food choice, physiological state, synchrony of activities, fusion-fission group dynamics, and predation risk, 3) identify the determinants of physiological stress, and their impact on animal distribution, and 4) determine the link between space use patterns and recruitment and adult mortality. This information will then become the basis for the development of a spatially explicit PVA. The proposed research will provide one of the few spatially explicit, mechanistic PVA. Moreover, plains bison are threatened in Canada, and our PVA will provide essential information about the harvest pressure that the population can sustain, given the predation pressure it already faces. The research will contribute to elucidating the ecological links among behaviour, demography, and distribution, while increasing our understanding of a threatened population.
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通常没有整合社会生态学和运动生态学的原则。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活动、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建立一个空间明确的PVA框架。
