摘要: We analyzed relative sensitivities of small- and medium-sized carnivores to livestock husbandry (stocking rates predator control) in Kalahari, South Africa, rangelands at a regional scale. monitored small using track counts on 22 Kalahari farms across land-use gradient ranging from low high stocking also interviewed each farm manager identify farmers' perception as potential predators for livestock. recorded 12 species farms. Stocking rate was the most important driving variable local carnivore abundance. Abundance all lowest where high. Most managers perceived carnivores, particular, African wildcat (Felis silvestris lybica), black-backed jackal (Canis mesomelas), caracal (Caracal caracal), Multiple regression analysis shows that jackal, wildcat, were negatively affected by control measures, whereas bat-eared fox (Otocyon megalotis), cape (Vulpes chama), small-spotted genet (Genetta genetta) positively affected. Our results show need expanding research conservation activities toward southern savannah rangelands. We, therefore, suggest developing monitoring program combining passive tracking with indigenous knowledge Khoisan Bushmen monitor populations, we recommend additional removal experiments manipulate densities.
