Habitat use of Long-crested Eagles in human-modified landscapes of KwaZulu-Natal, South Africa.
(2019)Loss of natural habitats due to land use change is threatening biodiversity globally, a cause for concern given the resulting loss of essential ecosystem services. Conservation of biodiversity within human-modified landscapes ... -
The habitat, nesting and foraging requirements of southern ground-hornbills in the Kruger National Park.
(2016)Southern ground-hornbills Bucorvus leadbeateri are large, terrestrial, carnivorous birds that inhabit the savanna and bushveld habitats of much of Africa, south of the equator. They were once prevalent in north-eastern ... -
Impacts of foraging behavior [sic] by Cape porcupines and their effects on nutrient cycling in mesic savannas.
(2021)Through feeding and associated activities, herbivores play a major role in determining the structure of savannas. The Cape porcupine (Hystrix africaeaustralis) is a semi-fossorial, large (ca. 12 kg) herbivorous rodent ... -
Influences of bush encroachment and intensity on small mammals in a mesic savanna, Pretoria, South Africa.
(2021)Abstract available in pdf. -
The influences of plant secondary metabolites on the foraging behaviour and carrying capacities of the african elephant, loxodonta africana.
(2017)Herbivore diet selection is influenced by plant quality and availability. For browsing and mixed-feeding herbivores, such as elephants, which consume trees and shrubs, plant quality is influenced by the concentrations of ... -
Interactive effects of fire history and elevated 2 temperature on aboveground productivity in a high 3 altitude mesic grassland in South Africa.
(2021)Abstract available in PDF. -
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.
(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. ...
