Relationship between group dynamics and spatial distribution of African elephants in a semi-arid environment

摘要: Group dynamics related to distribution of African elephants in the semi-arid environment Tsavo East National Park, Kenya was studied between 2007 and 2010. I examined seasonal lone bulls, bull groups, family units mixed groups group size. Lone bulls were widely distributed dry season localized wet season, whereas both seasons. On average size did not differ with seasons or areas, but larger observed preferred areas season. Family Although tended be large all also Large distributed, localized. The relationship attributed combination social, ecological poaching factors. This study provided insight into patterns that can applied security elephant population.
