摘要: AbstractWe test two hypotheses that could account for patch departure by large mammalian carnivores. One hypothesis is the unsuccessful-hunt hypothesis, where carnivores leave an area after unsuccessful hunt but continue hunting in same a successful hunt. The second patch-disturbance depart because of behavioral responses prey to predator presence. We used global positioning system collars monitor movements African lions (Panthera leo) and identified their kill sites distinguish between these hypotheses. Lions moved different (≥5 km away) 87% kills, which supports patch-departure behavior
