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

Exploring the connections between giraffe skin disease and lion predation

Rates at which predators encounter, hunt and kill prey are influenced by, among other things, the intrinsic condition of prey. Diseases can considerably compromise body condition, potentially weakening the ability of afflicted prey to avoid predation. Understanding predator–prey dynamics is particularly important when both species are threatened, as is the case with lions (Panthera leo) and giraffes (Giraffa camelopardalis). Importantly, an emergent disease called giraffe skin disease (GSD) may affect predatory interactions of lions and giraffes. Hypotheses suggest that GSD

Assessment of the impact of human-wildlife conflict on socio-economic livelihoods of communities bordering Bour-Algy Giraffe Sanctuary in Garissa, Kenya

Purpose: In the recent years, human-wildlife conflicts have been increasing and its implications on biodiversity conservation and livelihood is significant in the drylands of Kenya especially in Garissa County. The link between these conflicts and socio-economic livelihoods has however been less explored in northeast Kenya, which prompted an investigation into the impact of human-wildlife conflict on socio-economic livelihoods of communities bordering Bour-Algy Giraffe Sanctuary in Garissa County. Methodology: A survey was conducted on the locals from the location as well

Feeding behaviour of lions (Panthera leo) on a small reserve

The prey selection and predatory behaviour of a single pride of lions (Panthera leo) was studied in the 8500 ha Karongwe Game Reserve from 1999–2005. The study focused on the difference between prey selection in the first three years when a two-male coalition was present with a similar period thereafter when one of the males was removed and subadult males dispersed from the pride. A total of 662 kills were recorded, with blue wildebeest (Connochaetes taurinus), warthog (Phacochoerus africanus), waterbuck

The applicability of lion prey selection models to smaller game reserves in South Africa

Prey selection by lions (Panthera leo) reintroduced into small game reserves (typically <1000 km2) in South Africa was compared with results from larger (more naturally functioning) protected areas. Prey selection was used to calculate mean preference indices, and where sample size allowed, tested for significance of preference, as well as for comparisons with current estimates in the literature. The model by Hayward & Kerley (2005) was found to be 85% accurate, suggesting it is well suited as a predictive tool

Structure of herd in giraffe: Developmental changes of social relationship in calves

In the present study, I aim to clarify social structure and differences of social interaction among different aged giraffe’s (Giraffa Camelopardelis) in Katavi National Park, Tanzania. I recorded giraffe’s sex, herd size and individual identify by pattern of marking on their necks. I estimated age on the basis of body size. The study about social structure was conducted around HQ and IKUU. As a result, I observed more calves around HQ than IKUU. A previous study revealed that predation pressure

Population structure of giraffes is affected by management in the Great Rift Valley, Kenya

Giraffe populations in East Africa have declined in the past thirty years yet there has been limited research on this species. This study had four objectives: i) to provide a baseline population assessment for the two largest populations of Rothschild’s giraffes in Kenya, ii) to assess whether there are differences in population structure between the two enclosed populations, iii) to assess the potential and possible implications of different management practices on enclosed giraffe populations to inform future decision-making, and iv)

The role of nursery group guardian is not shared equally by female giraffe (Giraffa camelopardalis tippelskirchi)

Giraffe usually give birth to a single calf throughout the year, although some locations report that conceptions are more likely during the wet season (Shorrocks, 2016). Several mother‐calf pairs will gather to form a nursery group in which all calves and their mothers are all together (Foster & Dagg, 1972; Langman, 1977). In general, lactating females spend more time foraging or drinking than nonlactating females (Fischhoff et al., 2007; Hamel & Côté, 2008). Hence, sometimes females in a nursery group

Group sizes of giraffes in Kenya: the influence of habitat, predation and the age and sex of individuals

Giraffe group sizes appear to vary in response to localized ecological and environmental factors, but there has been little investigation of how social factors or predation risk affect group size in giraffes. We studied two adjacent, enclosed populations of Rothschild’s giraffes in Kenya, and used 591 records of groups to determine the relative influence of a series of variables on group size. One population was free from any risk of predation, while the other area contained a high density of
