据报道,捕食者和猎物的活动相互影响。然而,很少有研究阐明非洲豹何时可能遇到猎物。其中一个原因是人们对非洲森林哺乳动物的活动模式知之甚少。因此,我的目的是澄清豹和他们的猎物物种的活动模式,通过部署相机陷阱在地面上和树上的Mahale山脉国家公园,坦桑尼亚。总共分析了地面上设置的相机陷阱的4468个相机日和树上设置的相机陷阱的286个相机日。豹子与其主要猎物物种之间活动模式的重叠是使用系数Δ计算的。在研究地区至少发现了7只豹子。豹子全天都很活跃,在黎明和黄昏时达到顶峰。蓝duikersPhilantomba monticola,在Mahale消费最多的物种,主要是白天。豹子的活动模式与蓝小羚羊的活动模式中度重叠(Δ = 0.65)。当分别由树栖或陆地相机捕获检测时,豹子的活动模式与红尾猴的活动模式显示出中等(Δ = 0.61)或低(Δ = 0.42)重叠。马哈尔豹可能会在中午在地面上捕食蓝色小羚羊和树栖灵长类动物,也可能在晚上袭击栖息在树上的灵长类动物。未来在不同研究领域对豹子饮食的研究,以及豹子和其他动物之间活动模式的比较,将阐明豹子的生态学。
The activities of predators and prey have been reported to influence each other. However, few studies have clarified when African leopardsPanthera pardusare likely to encounter their prey. One reason for this is that the activity patterns of African forest mammals are poorly understood. Therefore, I aimed to clarify the activity patterns of leopards and their prey species by deploying camera traps on the ground and in trees in Mahale Mountains National Park, Tanzania. In total, 4468 camera days of camera traps set on the ground and 286 camera days of camera traps set in trees were analyzed. The overlap in activity patterns between leopards and their main prey species was calculated using coefficient Δ. At least seven leopards were identified in the study area. Leopards were active throughout the day, with crepuscular peaks at dawn and dusk. Blue duikersPhilantomba monticola, the most consumed species in Mahale, were predominantly diurnal. The activity patterns of leopards moderately overlapped with those of blue duikers (Δ = 0.65). The activity patterns of leopards showed a moderate (Δ = 0.61) or low (Δ = 0.42) overlap with those of red‐tailed monkeysCercopithecus ascaniuswhen detections were captured by arboreal or terrestrial cameras, respectively. Mahale leopards may hunt blue duikers and arboreal primates in the midday on the ground, and may also attack primates in roost trees at night. Future studies on the leopard diet in various study areas, as well as comparisons of activity patterns between leopards and other animals, will elucidate leopard ecology.
