Prey Preferences Of The African Wild Dog Lycaon Pictus (Canidae: Carnivora): Ecological Requirements For Conservation

Valuable conservation research on the African wild dog (Lycaon pictus) has identified that its current endangerment is primarily due to human persecution, although habitat alteration, interference competition with other large predators, and disease also are factors. Numerous studies have thus determined what should be avoided to sustain an African wild dog population, yet in this study we identify what is needed to conserve a wild dog population by using Jacobs’ index to determine its preferred prey species. Twenty-four assessments of

Prey preferences of the cheetah (Acinonyx jubatus) (Felidae: Carnivora): morphological limitations or the need to capture rapidly consumable prey before kleptoparasites arrive?

As a charismatic carnivore that is vulnerable to extinction, many studies have been conducted on predation by the cheetah Acinonyx jubatus. Cheetah are generally considered to capture medium‐sized prey; however, which species are actually preferred and why has yet to be addressed. We used data from 21 published and two unpublished studies from six countries throughout the distribution of the cheetah to determine which prey species were preferred and which were avoided using Jacobs’ index. The mean Jacobs’ index value

Prey preferences of the spotted hyaena ( Crocuta crocuta ) and degree of dietary overlap with the lion (Panthera leo)

Spotted hyaenas Crocuta crocuta were once considered mere scavengers; however, detailed research revealed that they are very efficient predators. Information on what spotted hyaenas actually prefer to prey on and what they avoid is lacking, as well as the factors that influence prey selection. Data from 14 published and one unpublished study from six countries throughout the distribution of the spotted hyaena were used to determine which prey species were preferred and which were avoided using Jacobs’ index. The mean

Prey preferences of the lion (Panthera leo)

Lions Panthera leo are generally thought to prey on medium to large ungulates. Knowledge of which species are actually preferred and which are avoided is lacking, however, as is an understanding of why such preference or avoidance may arise. An analysis of 32 studies over 48 different spatial locations or temporal periods throughout the distribution of the lion shows that it preferentially preys upon species within a weight range of 190–550 kg. The most preferred weight of lion prey is
