Lions and Leopards as Game Ranch Animals  [cached]
Leo Braack
Koedoe : African Protected Area Conservation and Science , 1998, DOI: 10.4102/koedoe.v41i1.239
Abstract: Ecotourism is a major and burgeoning industry in southern Africa, near the top of the list as an attractant of foreign revenue and crucial in the economics of several countries.
Using Landscape and Bioclimatic Features to Predict the Distribution of Lions, Leopards and Spotted Hyaenas in Tanzania's Ruaha Landscape  [PDF]

Abstract: Tanzania's Ruaha landscape is an international priority area for large carnivores, supporting over 10% of the world's lions and important populations of leopards and spotted hyaenas. However, lack of ecological data on large carnivore distribution and habitat use hinders the development of effective carnivore conservation strategies in this critical landscape. Therefore, the study aimed to (i) identify the most significant ecogeographical variables influencing the potential distribution of lions, leopards and spotted hyaenas across the Ruaha landscape; (ii) identify zones with highest suitability for harbouring those species; and (iii) use species distribution modelling algorithms (SDMs) to define important areas for conservation of large carnivores. Habitat suitability was calculated based on environmental features from georeferenced presence-only carnivore location data. Potential distribution of large carnivores appeared to be strongly influenced by water availability; highly suitable areas were situated close to rivers and experienced above average annual precipitation. Net primary productivity and tree cover also exerted some influence on habitat suitability. All three species showed relatively narrow niche breadth and low tolerance to changes in habitat characteristics. From 21,050 km2 assessed, 8.1% (1,702 km2) emerged as highly suitable for all three large carnivores collectively. Of that area, 95.4% (1,624 km2) was located within 30 km of the Park-village border, raising concerns about human-carnivore conflict. This was of particular concern for spotted hyaenas, as they were located significantly closer to the Park boundary than lions and leopards. This study provides the first map of potential carnivore distribution across the globally important Ruaha landscape, and demonstrates that SDMs can be effective for understanding large carnivore habitat requirements in poorly sampled areas. This approach could have relevance for many other important wildlife areas that only have limited, haphazard presence-only data, but which urgently require strategic conservation planning.

Activity patterns in southern Kalahari leopards  [cached]

African Zoology , 2011,
Abstract: Preliminary results based on two satellite-tracked adult leopards in the arid, open savanna of the southern Kalahari indicated that most movement occurred at night, with some movement in the daytime to seek shade.
Natural mortality amoung four common ungulate species on Letaba Ranch, Limpopo Province, South Africa  [cached]

Koedoe : African Protected Area Conservation and Science , 2002, DOI: 10.4102/koedoe.v45i1.12
Abstract: Five years of mortality data of impala Aepyceros melampus, blue wildebeest Connochaetes taurinus, buffalo Syncerus caffer and kudu Tragelaphus strepsiceros have been used to describe the minimum mortality profiles of the respective species in an open savanna system with the full compliment of predators. Predation is the principle cause of natural mortalities on the study site, Letaba Ranch, which is adjacent to the Kruger National Park. The principle cause of impala mortality are leopards Panthera pardus and wild dogs Lycaon pictus. Lion Panthera leo were major contributors to the mortality of wildebeest and buffalo. Anthrax Bacillus anthracis was the main cause of kudu mortality.
Etienne van Heerden: Mooi loop met die woorde!
HP Grebe
Tydskrif vir letterkunde , 2006,
Abstract: The literary press received Etienne van Heerden's recent novel In stede van die liefde (Instead of love; In cities of love, 2005) positively. The Afrikaans cultural organisation, the ATKV (Afrikaanse Taal- en Kultuurvereniging), for instance awarded the novel its 2005 prize for excellent popular prose. Nonetheless, not all is what it seems. Some literary critics rather hesitantly suggested that Van Heerden's narration and style were less fluent than his previous novels. This article aims to uncover the reasons for these reservations by looking into the author's use of the Afrikaans language. The paper suggests that the novel could have been edited more thoroughly. The numerous language errors and idiosyncrasies in the text mar what should have been a fascinating reading experience.

Multivariate analysis of the hunting tactics of Kalahari leopards  [cached]

Koedoe : African Protected Area Conservation and Science , 1997, DOI: 10.4102/koedoe.v40i1.262
Abstract: The hunting tactics of male and female leopards in the southern Kalahari were analysed for prey-specific patterns. The field study was based on tracking leopard spoor in the sandy substrate of the Kalahari. Visual profiles for each type of prey were compiled for various facets of hunting. Data sets were analysed further, using Correspondence Analysis and Detrended Correspondence Analysis. The results indicate that multivariate analysis can be used to demonstrate prey-specific hunting tactics in Kalahari leopards. In using a scarce prey base, Kalahari leopards seem to be number maximisers as they are unselective of prey type, age or sex. The presence of prey-specific hunting tactics may indicate a move along a continuum towards some degree of energy maximisation.

Disturbance bias when tracking Kalahari leopards Panthera pardus by spoor  [cached]
J du P Bothma,E.A.N le Riche
Koedoe : African Protected Area Conservation and Science , 1993, DOI: 10.4102/koedoe.v36i2.379
Abstract: The possible habituation of leopards to spoor trackers or increased disturbance by trackers affecting leopards in the Kalahari was examined. The median flight distance class interval was 0,6-1,0 km and there was no evidence of either habituation or increased disturbance.
