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 ... -
Aspects of the ecology of African woolly-necked storks (Ciconia microscelis) in an anthropogenic changing landscape in KwaZulu-Natal, South Africa.
(2018)Urbanisation is the fastest-growing forms of anthropogenic land use change and a major threat to biodiversity worldwide. However, despite the negative impacts of urbanisation on native species, some species persist in ... -
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 ... -
Taxonomic, functional, and avian community dynamics in selected Southern Mistbelt Forests of southern KwaZulu-Natal and the Eastern Cape, South Africa.
(2020)Human population increase and landscape transformation result in the reduction of natural habitats, such as forests, causing changes in forest patch composition, habitat amount, patch size, isolation, shape, and edges. ... -
Building a conservation strategy for the harpy eagle in the Amazon Forest.
(2020)Apex predators are threatened worldwide and are considered a priority in the conservation biology agenda. Their decline is associated with habitat loss and degradation, and persecution arising from perceived and actual ... -
Aspects of the ecology of three mongoose species along a rural–urban landscape gradient of KwaZulu- Natal, South Africa.
(2020)Many small carnivore species are of particular concern for conservation because of their elusive behaviour, diminutive size and crepuscular habits. Management and research tend to be challenging and thus is often limited. ... -
Aspects of common hippopotamus (Hippopotamus amphibius) behavioural ecology and their consequences in managed systems in South Africa.
(2020)Abstract available in PDF. -
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. ... -
Effects of land-use changes on the distribution and use of Ficus species by frugivores in the urban mosaic landscape of Durban, KwaZulu-Natal, South Africa.
(2021)Land-use change is one of the greatest threats to biodiversity. Over the years, these changes potentially reduced ecosystems capacity to sustain food production for vertebrates. Ficus (figs; Moraceae) is one of the largest ... -
Diversity of edible insects and their related indigenous knowledge: evidence from KwaZulu-Natal and Limpopo provinces, South Africa.
(2021)Entomophagy is an ancient indigenous practice that has played a significant role in human nutrition around the world. In addition, the traditional use of edible insects forms an important part of food culture in Africa. ... -
Evolution of tangle-veined flies: systematics, biogeography and functional traits in southern African Nemestrininae (Nemestrinidae)
(2021)The evolution of traits and biogeography of the three southern African endemic genera of the Nemestrinidae: Moegistorhynchus, Prosoeca and Stenobasipteron. These genera are of particular interest due to the exaggerated ...
