Behaviour of bottlenose dolphins : inference for dolphin tourism off Durban, South Africa.
(2008)During long-term studies of dolphins, the number of individuals in the population being studied are constantly monitored using the technique of photo-identification. This constant monitoring makes use of different ... -
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 ... -
The breeding system and demography of the Transvaal Sesame-bush, Sesamothamnus lugardii (Pedaliaceae)
(2019)The aim of this research was to assess the breeding system, pollination relationship and demography of the Transvaal Sesame-bush, Sesamothamnus lugardii N. E. Br. Ex Stapf. (Pedaliaceae). S. lugardii is an arid savanna ... -
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 ... -
Changes in adult female white rhino seasonal home ranges in relation to variation in food quality and availability.
(2013)As the dry season progresses across southern Africa, the availability and quality of food declines for large herbivores. Female white rhinos compensate for these declines by expanding and/or shifting their home ranges. ... -
The comparative ecology of Natal's smaller estuaries.
(1983)Fifty one of Natal's 73 estuaries have been almost completely overlooked in terms of any scientific study, despite which a marine nursery function has commonly been attributed to each of them. In the knowledge that many ... -
Comparative water relations of Protea nitida seedlings and sprouters after fire.
(1990)This study was undertaken to determine the effect of vegetation structure (the ratio of re-seeding to re-sprouting plants) on post-fire catchment water yield. Plant communities are the only components of mountain catchments ... -
The competitive effect of vetiver grass on native grasses and implications for grassland rehabilitation in South Africa.
(2018)Astract available in PDF file. -
The conservation ecology of the African tigerfish Hydrocynus vittatus in the Kavango River, Namibia.
(2017)Abstract available in PDF file. -
The contribution of goats to household food security in selected communities of KwaZulu-Natal, South Africa.
(2021)The growth of the human population in the world has been occurring at a rapid rate. This presents a challenge of how the world food demands will be met. These challenges are always felt the most in developing countries, ... -
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 ... -
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 ... -
Development and application of novel ornithological survey methods for the detection of cryptic avian indicator species that predict grassland health.
(2021)The anthropogenic pressure on South African grasslands to meet the needs of the burgeoning human population has exposed them to extensive permanent transformation and degradation. Indicator species may identify changes ... -
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. ... -
The ecological implications of sea-level rise and storms for sandy beaches in KwaZulu-Natal.
(2008)The aesthetic appeal of beaches has made coastal properties prime sites for development. However, this development has been mismanaged and is within the littoral active zone. Beaches retreat landwards as sea levels rise, ... -
The ecology and conservation biology of Lilian's lovebird Agapornis lilianae in Malawi.
(2014)Despite their popularity, parrots are the world’s most threatened birds. Lovebirds (Agapornis) are very popular pet and aviary birds and as ecologically specialised species in the wild, they are also among the most threatened ... -
Ecology and evolution of the specialized hemipepsis-wasp (Hymenoptera : Pompilidae) pollination guild in South Africa.
(2011)Pollinators are believed to have played a key role in the radiation of flowering plants. The Grant-Stebbins model of pollinator-mediated speciation, in which evolutionary shifts between pollinators result in phenotypic ... -
The ecology and parasitology of small mammals from selected sites in Swaziland.
(2007)The study was initially a long term study of the ecology of small mammals at Mlawula Nature Reserve in the eastern part of Swaziland. Due to the drought and dwindling numbers of rodents in the reserve the study was ... -
The ecology of black-backed jackal (Canis mesomelas) on farmlands in the Midlands of KwaZulu-Natal, South Africa.
(2014)Agricultural development is progressively being attributed as a cause of biodiversity loss. Despite this development, some species do successfully inhabit these transformed habitats and benefit from increased food and ...
