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.
期刊介绍:
African Journal of Ecology (formerly East African Wildlife Journal) publishes original scientific research into the ecology and conservation of the animals and plants of Africa. It has a wide circulation both within and outside Africa and is the foremost research journal on the ecology of the continent. In addition to original articles, the Journal publishes comprehensive reviews on topical subjects and brief communications of preliminary results.
