Key factors driving the foraging ecology of Oribi : fear, cattle and the quality and quantity of food.
(2015)Body size and digestive physiology are two factors that influence herbivores foraging behaviour, habitat use and potential to compete with other animals. The aim of this study was to determine how seasonal changes in grass ... -
Local and landscape drivers of avian diversity facets in the naturally fragmented Southern Mistbelt forests of KwaZulu-Natal and Eastern Cape, South Africa.Abashayeli bendawo bezinhlobo zezinyoni ezahlukene emahlathini ase-Southern Mistbelt ahlukaniswe ngokwemvelo ezifundazweni zakwa KwaZulu-Natal nase Eastern Cape eNingizimu Afrika.
(2022)Forest fragmentation is a process whereby a forest landscape is subdivided into smaller and more isolated fragments embedded within a matrix of anthropogenic land-uses. The effects of increasing anthropogenic practices ... -
Macroinvertebrates as ecological indicators of the wellbeing of the lower uMvoti and Thukela Rivers, KwaZulu-Natal, South Africa.
(2018)The excessive use of water resources and climate change stressors is impacting the quality and quantity of surface aquatic ecosystems in South Africa, a semi-arid country. Although South Africa is considered to be a ... -
Management of multiple stressors to the lower reach of the Thukela River ecosystem.
(2019)South Africa is a water scarce country which is experiencing an increase in the demand and development of water resources. The Thukela River in KwaZulu-Natal is the second largest river in South Africa and the largest in ... -
Managing nesting hawksbill turtles (Eretmochelys imbricata) on a small tropical island.
(2018)Although human impact has caused the hawksbill turtle (Eretmochelys imbricata) to be on the brink of extinction, conservation efforts are on the increase and management strategies are being re-defined to manage the species ... -
Monitoring and assessment of macroinvertebrate communities in support of river health management in KwaZulu-Natal, South Africa.
(2017)Conservation of freshwater systems is globally weak and generally declining, with rivers and wetlands being the most threatened ecosystems by anthropogenic impacts. Though they are highly import, freshwater ecosystems ... -
Morphometrics, ecotoxicology and stable isotope ecology of Nile crocodiles (Crocodylus niloticus) in KwaZulu-Natal, South Africa.
(2015)Abstract available in PDF. -
Movement, home range and habitat use in leopard tortoises (Stigmochelys pardalis) on commercial farmland in the semi-arid Karoo.
(2016)Given the ever-increasing demand for resources due to an increasing human population, vast ranges of natural areas have undergone land use change, either due to urbanisation or production and exploitation of resources. In ... -
Niche requirements and breeding system of Hypericum pseudohenryi, an invasive plant species in South Africa.
(2016)Invasive alien species threaten ecosystems throughout South Africa through alteration of the habitat and loss of biodiversity. Emerging invasive alien plants are those that have small populations, but have the potential ... -
Olfactory communication of the white rhinoceros (Ceratotherium simum)
(2017)Many mammal species communicate olfactorily via specialised scent glandular secretions, urine and/or dung. Despite a large body of work on olfactory communication, the extent to which mammals communicate via dung odours, ... -
Parthenium hysterophorus distribution and efficacy of control in Hluhluwe-Imfolozi Park, northern KwaZulu-Natal.
(2020)Abstract available in pdf. -
Pollination ecology and the functional significance of unusual floral traits in two South African stapeliads.
(2017)Carrion and dung mimicking plants often exhibit unusual floral traits which are believed to attract necro- and coprophagous insects as pollinators. Our understanding of these unusual traits and their functions is very ... -
Pollinator-driven divergence among populations of a self-fertilizing lily, Hesperantha coccinea (Iridaceae).
(2021)Two major trends in floral evolution – pollinator shifts and the evolution of autonomous selffertilisation – are generally considered alternative evolutionary responses to pollen-limitation of plant reproductive success. ... -
Population dynamics and relocation success of the oribi antelope (Ourebia ourebi) in KwaZulu-Natal, South Africa.
(2015)In South Africa, oribi (Ourebia ourebi) antelope are listed as vulnerable. The lack of understanding of their population dynamics makes it difficult for oribi conservation. To address these gaps, I used the Oribi Working ... -
The potential overlap in habitat space of caracal (Caracal caracal) and blue duiker (Philantomba monticola) in KwaZulu-Natal, South Africa : an environmental niche modelling approach.
(2016)According to the mesopredator release hypothesis, when apex predators disappear from an ecosystem, the number of mesopredators increase and thus predation of prey species increases. Since the extermination of large predators ... -
The prevalence and implications of non-native wild boar Sus scrofa in KwaZulu-Natal, South Africa.
(2023)Humans’ introduction of species into areas where they do not naturally occur has led to ecological and economic havoc. Introduced species can become invasive, exerting negative pressures on native species and the ... -
Protected area management and planning challenges: sustainability and integrity – a cursory investigation of the role of the management plan.
(2021)Formally established protected areas in South Africa date back to the turn of the 19th century, yet requirements for protected area management plans only became mandatory approximately a century later. Before the ... -
The relative tolerance of mesic grassland species to defoliation and competition.
(2018)Effective grazing management is dependent on understanding grass species responses to herbivory. These responses to herbivory can be broadly grouped into 3 categories, namely decreaser (plants that decline in abundance) ... -
Response of estuarine and freshwater macroinvertebrate assemblages to habitat, water quality, flow and land use change in the lowland Amatikulu/Nyoni catchment.
(2018)Water has become a scarce commodity in Sub-Saharan Africa and in drought prone South Africa. Due to the extensive utilization of water resources in South Africa, management and monitoring of our rivers and estuaries is ... -
Role and effects of wild southern African ungulates on seed dispersal of selected alien invasive plants.
