Abstract

The aim of this study was to describe and compare the dietary composition of lion (Panthera leo), cheetah (Acinonyx jubatus) and spotted hyaena (Crocuta crocuta) populations in Liwonde National Park, Malawi. Using scat analyses and direct observations, our results indicate a high degree of dietary overlap (Oab > 0.70), indicative of intraguild competition, and all carnivores exhibited a dietary preference for kudu (Tragelaphus strepsiceros). At present, coexistence is potentially facilitated by low carnivore densities and spatiotemporal responses. We recommend that carnivore diets and niche partitioning strategies continue to be investigated as carnivore populations increase.

马拉维利旺德国家公园大型食肉动物的饮食组成和重叠
本研究的目的是描述和比较马拉维Liwonde国家公园中狮子(Panthera leo)、猎豹(Acinonyx jubatus)和斑点鬣狗(Crocuta Crocuta)种群的饮食组成。通过粪便分析和直接观察,我们的结果表明存在高度的饮食重叠(Oab > 0.70),表明存在野生动物内部竞争,并且所有食肉动物都表现出对kudu (Tragelaphus strepsiceros)的饮食偏好。目前,低食肉动物密度和时空响应可能促进共存。我们建议随着食肉动物种群的增加,继续研究食肉动物的饮食和生态位分配策略。
