Additive opportunistic capture explains group hunting benefits in African wild dogs
African wild dogs (Lycaon pictus) are described as highly collaborative endurance pursuit hunters based on observations derived primarily from the grass plains of East Africa. However, the remaining population of this endangered species mainly occupies mixed woodland savannah where hunting strategies appear to differ from those previously described. We used high-resolution GPS and inertial tech...
متن کاملEnergy cost and return for hunting in African wild dogs and cheetahs
African wild dogs (Lycaon pictus) are reported to hunt with energetically costly long chase distances. We used high-resolution GPS and inertial technology to record 1,119 high-speed chases of all members of a pack of six adult African wild dogs in northern Botswana. Dogs performed multiple short, high-speed, mostly unsuccessful chases to capture prey, while cheetahs (Acinonyx jubatus) undertook...
متن کاملForest-dwelling African wild dogs in the Bale Mountains, Ethiopia
Ethiopia harbours several relict populations of African wild dogs Lycaon pictus, but most data is anecdotal. Wild dogs are known to occur atypically in the montane wet forest of Harenna in the southern slopes of Bale Mountains National Park, southeastern Ethiopia. A questionnaire-survey of 90 Harenna forest residents investigated the local people’s knowledge and attitudes to wild dogs. Wild dog...
متن کاملAfrican wild dogs test the 'survival of the fittest' paradigm.
Charles Darwin first used the term 'survival of the fittest' in the 5th edition of The origin of species. A literal interpretation implies that predators will selectively prey upon the weakest members of a population. We demonstrate that this is true for African wild dogs hunting impala.
متن کاملContact with Domestic Dogs Increases Pathogen Exposure in Endangered African Wild Dogs (Lycaon pictus)
BACKGROUND Infectious diseases have contributed to the decline and local extinction of several wildlife species, including African wild dogs (Lycaon pictus). Mitigating such disease threats is challenging, partly because uncertainty about disease dynamics makes it difficult to identify the best management approaches. Serious impacts on susceptible populations most frequently occur when generali...
