Inbreeding avoidance influences the viability of reintroduced populations of African Wild Dogs (Lycaon pictus)
(Plos, 2012-05)The conservation of many fragmented and small populations of endangered African wild dogs (Lycaon pictus) relies on understanding the natural processes affecting genetic diversity, demographics, and future viability. We ... -
Inbreeding, heterozygosity and fitness in a reintroduced population of endangered African wild dogs (Lycaon pictus)
(Springer, 2011-03-17)It is crucial to understand the genetic health and implications of inbreeding in wildlife populations, especially of vulnerable species. Using extensive demographic and genetic data, we investigated the relationships among ... -
The influence of prey , pastoralism and poaching on the hierarchical use of habitat by an apex predator
(SAWMA, 2015)As an apex predator, habitat selection by African lions,Panthera leo, is primarily determined by bottom-up processes; however, increasing anthropogenic pressures may alter these relationships. Using camera traps and track ... -
Interactive effects of species richness and species traits on functional diversity and redundancy
(Springer, 2012-01)The importance of species diversity for ecosystem function has emerged as a key question for conservation biology. Recently, there has been a shift from examining the role of species richness in isolation towards understanding ... -
Landscape suitability in Botswana for the conservation of its six large African carnivores
(PloS, 2014-06-20)Wide-ranging large carnivores often range beyond the boundaries of protected areas into human-dominated areas. Mapping out potentially suitable habitats on a country-wide scale and identifying areas with potentially high ... -
Leopard Panthera pardus density in southern Mozambique: evidence from spatially explicit capture-recapture in Xonghile Game Reserve
(2020)Rigorous status estimates of populations of large carnivores are necessary to inform their management and help evaluate the effectiveness of conservation interventions. The African leopard Panthera pardus faces rising ... -
Lions at the gates: trans-disciplinary design of an early warning system to improve human-lion coexistence
(2019)Across Africa, lions (Panthera leo) are heavily persecuted in anthropogenic landscapes. Trans-disciplinary research and virtual boundaries (geofences) programmed into GPS-tracking transmitters offer new opportunities to ... -
Lions Panthera leo prefer killing certain cattle Bos taurus types
(2020)Simple Summary Livestock production continues to increase throughout the world. Meanwhile, lions are becoming increasingly endangered, in part due to the severe conflict arising from cattle predation. Because cattle closely ... -
Livestock predation in South Africa: The need for and value of a scientific assessment
(Academy of Science of South Africa, 2017) -
Local ecological knowledge and community-based management of wildlife resources: A study of the Mumbwa and Lupande Game management areas of Zambia.
(Environmental Education Association of Southern Africa, 2017)The aim of this study was to investigate the scope of local ecological knowledge (LEK) in the Lupande and Mumbwa Game Management Areas (GMAs) of Zambia and to assess the extent to which such knowledge has been used in the ... -
Mentorship for young scientists

Methods and approaches for the management of arthropod border incursions
(Springer, 2016)Biological invasions are increasing and are strongly associated with negative agricultural, economic and ecological impacts. It is increasingly recognized that the primary focus in minimizing biological invasions should ... -
Mongooses on the move: an apparent case of interspecific cooperative vigilance between carnivores
(SOUTHERN AFRICAN WILDLIFE MANAGEMENT ASSOC, 2006-10)Meerkats (Suricata suricatta) and yellow mongooses (Cynictis penicillata) show antipredator behaviours which, at least in the former species, can take the form of cooperation between pack members. Here, we describe an ... -
Niche overlap and dietary resource partitioning in an African large carnivore guild
(2019)Understanding and quantifying a large carnivores' feeding behaviour is a key component in determining its functional significance in an ecosystem, both in terms of its top-down influence on prey species, but also its ... -
Plasticity and specialisation in the isotopic niche of African clawless otters foraging in marine and freshwater habitats
(2019)Individual-level behavioural plasticity resulting from differences in environmental conditions is prevalent in many organisms and may result in phenomena such as dietary- or habitat specialisation. The isotopic niche of ... -
Post-dispersal fate of Acacia seeds in an African savanna
(SOUTHERN AFRICAN WILDLIFE MANAGEMENT ASSOC, 2005-10)African Acacia species are often major contributors to the progressive increase in the woody component of savannas, a phenomenon commonly referred to as bush encroachment. In Hluhluwe-iMfolozi Park, the numbers of adult ... -
The potential for large carnivores to act as biodiversity surrogates in southern Africa
(Springer, 2008)Biodiversity in southern Africa is globally extraordinary but threatened by human activities. Although there are considerable biodiversity conservation initiatives within the region, no one has yet assessed the potential ... -
Pre-release hunting training and post-release monitoring are key components in the rehabilitation of orphaned large felids
(SA ePublications, 2011-04)The rehabilitation of orphaned animals is commonly practiced but rarely scientifically documented. The behavioural development before release (e.g. regarding hunting skills) is particularly important for ensuring animals ... -
Rates and causes of mortality in Endangered African wild dogs Lycaon
(Fauna & Flora International, UK, 2007-05)Effective species conservation depends upon correctly identifying the threats that cause decline or hinder recovery. Because estimates of the relative viability of different populations of Endangered African wild dogs ...
