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 ... -
Controlling woody plant encroachment in a southern African savanna.
(2021)Woody plant encroachment is considered one of the most extensive forms of degradation affecting savannas in arid and semi-arid ecosystems. Thus, reactive interventions such as chemical and mechanical controls, as well ... -
Forest mammalian community dynamics and human wildlife interactions in the Southern Mistbelt Forests of KwaZulu-Natal and Eastern Cape, South Africa.
(2021)African and Asian forests are well known for their high faunal and floral diversity; however, many forests have been left degraded or cleared because of anthropogenic activities from the past and present. In particular, ... -
Aspects of monitoring wild and captive Nile crocodile (Crocodylus niloticus) populations in southern Africa.
(2021)As biodiversity across the globe declines because of anthropogenic activities, the need for conservation efforts increases. For conservation efforts to be successful, it is imperative that detailed information about ... -
Crocodile (Crocodylus niloticus) meal diets as a potential for replacement of fishmeal protein in commercial production of Mozambique tilapia (Oreochromis mossambicus)
(2022)Fishmeal production is mainly sourced from the forage fish species. Fish caught for fishmeal production potentially represents a loss in producing higher trophic level species in the ecosystem. Low stock abundance reduces ... -
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 ... -
Aspects of the ecology and persistence of vervet monkeys in mosaic urban landscapes in KwaZulu-Natal, South Africa.
(2022)The geological era in which we live is termed the Anthropocene and is causing the greatest loss of biodiversity and species brought on by a single species: Homo sapiens. The human population places great demands on the ...
