Lion predation on elephants in the Savuti, Chobe National Park, Botswana
Item type: Journal Article • Journal: African Zoology • Authors: R. John Power --- Carnivore Conservation Group, Endangered Wildlife Trust, De Beers Venetia Limpopo Nature Reserve, South Africa R. X. Shem Compion --- Carnivore Conservation Group, Endangered Wildlife Trust, De Beers Venetia Limpopo Nature Reserve, South AfricaLions rarely prey on elephants. Botswana‘s Savuti lions, however, switch to preying on elephants during the late dry season (August–November), and the frequency of this has increased in the last two decades (1985–2005). An opportunity to document this phenomenon was... -

Rathbun --- Department of Ornithology and Mammalogy, California Academy of Sciences, U.S.A.The Sahara Desert was recently proposed as the agent of vicariant speciation in the North African elephant-shrew (order Macroscelidea, Elephantulus rozeti). Based on evidence from molecular dating, however, this speciation event was estimated as having occurred in the Miocene, an... -
