Urban ecology of the crowned eagle stephanoaetus coronatus in KwaZulu-Natal, South Africa.
(2015)Urban environments comprise a complex and dynamic landscape, and urban sprawl is irreversibly transforming large areas of land globally. Increasingly, the need for incorporating ecosystem services into urban landscapes ... -
Evolution of wind pollination in Leucadendron (Proteaceae) : experimental evidence and floral trait shifts.
(2014)Evolutionary transitions from insect to wind pollination are thought to have occurred many times during the angiosperm radiation. This transition is commonly associated with a suite of distinctive floral traits such as ... -
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 ... -
Aspects of the ecology of trumpeter hornbill (bycanistes bucinator) across urban-forest mosaics in KwaZulu-Natal, South Africa.
(2016)Abstract available in PDF file. -
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 ... -
Assessing the success of red-billed oxpecker translocations as a conservation tool in KwaZulu-Natal, South Africa.
(2016)There are numerous factors that contribute to a bird species becoming threatened and in need of increased conservation efforts in order to survive. Compared with fossil records, current extinction rates are much higher ... -
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 ... -
A biogeographic study of the KwaZulu-Natal sandstone sourveld patches within the eThekwini Municipal Area.
(2016)KwaZulu-Natal Sandstone Sourveld (KZNSS) is an endangered vegetation type in South Africa. Approximately 68% of KZNSS is transformed, with remaining patches existing within an urban and suburban matrix. Fragmented patches ... -
Varying degrees of fear : how do large herbivores adjust their anti-predator behaviour in response to different predators?
(2016)Large predators are returning to areas where they have previously been absent through both predator reintroductions and natural range expansion. As a result, these re/introductions are changing the nature of predator-prey ... -
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 ... -
Assessing anthropogenic impacts on the persistence of forest mammals within the Indian Ocean coastal belt of southern KwaZulu-Natal province.
(2016)Abstract available in PDF file. -
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 ... -
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, ... -
The conservation ecology of the African tigerfish Hydrocynus vittatus in the Kavango River, Namibia.
(2017)Abstract available in PDF file. -
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 ... -
Understanding the effects of changing climate and land use on woody plant encroachment in South African grasslands and savannas.
(2017)The increase in dominance of woody species, observed in many grasslands and savannas worldwide, highlights the sensitivity of woody herbaceous biomass ratios to changed environmental conditions. While the major factors ... -
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 ... -
Use of freshwater fish to evaluate the wellbeing of selected rivers in KwaZulu-Natal, South Africa.
(2017)Freshwater makes up just 0.01 % of the total water on earth but the fish species inhabiting it make up around 20 % of all vertebrate species. For centuries, human settlements have relied upon freshwater fish for food, ... -
