Sampling error in non-invasive genetic analyses of an endangered social carnivore
(Springer, 2009-12)Modern non-invasive genetic technologies are useful in studies of rare and difficult-to-observe species. An examination of endangered African wild dog (Lycaon pictus) faecal DNA revealed that 11.4% of samples were assigned ... -
Seasonal selection of key resources by cattle in a mixed savannah-wetland ecosystem increases the potential for conflict with lions
(2019)In Africa's pastoral conservation landscapes, apex predators frequently kill livestock. Retaliatory persecution such as poisoning threatens predators, but also non-target biota. Several factors influence conflict severity, ... -
Seasonal, altitudinal and host plant-related variation in the abundance of aphids (Insecta, Hemiptera) on sub-Antarctic Marion Island
(Springer, 2011-04)Although aphids are the most species-rich group of invasive alien insects across the Southern Ocean Islands, their biology on the islands is poorly known. In this study, host plant-related, seasonal and altitudinal variation ... -
Shell availability and use by the hermit crab Clibanarius virescens along the Eastern Cape coast, South Africa
(2007)Patterns of shell availability and use of the intertidal yellow-banded hermit crab Clibanarius virescens were studied by means of field sampling. Data were collected at three sites (Dwesa, Nqabara and Mendwana) along the ... -
Size, shape and maintenance matter: A critical appraisal of a global carnivore conflict mitigation strategy - Livestock protection kraals in northern Botswana
(Elsevier, 2018)Fortified kraals are predator-proof enclosures designed to protect livestock at night. Globally, they show great promise in reducing depredation by carnivores, thus promoting co-existence with people. Their efficacy depends ... -
South Africa's newly approved marine protected areas have increased the protected modelled habitat of nine odontocete species
(2020)Marine protected areas (MPAs) are important for the preservation of ecosystem functioning, ecosystem services, resilience and biodiversity around the world. In South Africa, the role of MPAs in the protection of cetaceans ... -
Space Use of African Wild Dogs in Relation to Other Large Carnivores
(PloS, 2014-06-05)Interaction among species through competition is a principle process structuring ecological communities, affecting behavior, distribution, and ultimately the population dynamics of species. High competition among large ... -
Species distribution modelling of Bryde’s whales, humpback whales, southern right whales, and sperm whales in the southern African region to inform their conservation in expanding economies
(2020)In southern African waters, information about species distribution and habitat preferences of many cetacean species is limited, despite the recent economic growth that may affect them. We determined the relative importance ... -
Spider responses to alien plant invasion: the effect of short- and long-term Chromolaena odorata invasion and management
(British Ecological Society, 2008-07)Invasions by alien plants into unspoiled ecosystems are a cause for concern because the pristine systems are important stores of biodiversity. Indeed, the introduction of non-indigenous species into protected areas is a ... -
Survival of Cheetahs Relocated from Ranchland to Fenced Protected Areas in South Africa
(Wiley-Blackwell, 2009-03)In South Africa, wildlife can be privately owned and utilized for economic gain, with the consequent formation of thousands of wildlife ranches that are stocked with wildlife for the main purpose of hunting and live sale. ... -
Survival rates and causes of mortality of leopards Panthera pardus in southern Africa
(Fauna & Flora International, 2015)Estimation of survival rates is important for developing and evaluating conservation options for large carnivores. However, telemetry studies for large carnivores are often characterized by small sample sizes that limit ... -
Tourists' willingness to pay to view otters along the Wild Coast, South Africa: a potential for increased ecotourism
(2005-12)This article reports on tourists’ willingness to pay to view Cape clawless otters Aonyx capensis along the Eastern Cape Wild Coast, South Africa. We collected data from a survey carried out using a structured, ... -
Translocating lions into an inbred lion population in the Hluhluwe-iMfolozi Park, South Africa
(Blackwell, 2008)A fundamental problem in conservation biology is the risk of inbreeding in fragmented and declining populations. In the Hluhluwe-iMfolozi Park (HiP), a small, enclosed reserve in South Africa, a large lion Panthera leo ... -
Trophic scaling and occupancy analysis reveals a lion population limited by top-down anthropogenic pressure in the Limpopo National Park, Mozambique
(PloS, 2014-06-10)The African lion (Panthera Leo) has suffered drastic population and range declines over the last few decades and is listed by the IUCN as vulnerable to extinction. Conservation management requires reliable population ... -
Use of site occupancy models for targeted monitoring of the cheetah
(Zooloical Society of London, 2014-03)The cheetah Acinonyx jubatus has suffered dramatic range contractions and population declines as a result of habitat degradation, prey depletion and conflict with humans. Of further concern is that many of Africa’s ... -
Wildlife abundance and diversity as indicators of tourism potential in Northern Botswana
(Public Library of Science, 2015)Wildlife tourism can provide economic incentives for conservation. Due to the abundance of wildlife and the presence of charismatic species some areas are better suited to wildlife tourism. Our first objective was to develop ...
