Ecological aspects of vegetation establishment on landfills.
(2003)A high level of plant mortality on the Bisasar Road landfill, Durban, South Africa initiated an investigation into the primary causes of the mortalities and a search for potentially tolerant plant species. Field studies ... -
The ecology of ungulates in the Waterberg Plateau National Park, Namibia.
(2019)Although ungulate species form an important component of Namibia’s economy through tourism, their population sizes vary substantially in relation to irregular rainfall, poaching, predation and competition, amongst other ... -
Ecosystem modelling of the data-limited, oligotropic KwaZulu-Natal Bight, South Africa.
(2012)Ecosystem modelling allows for an understanding of the structure and functioning of ecosystems. During this study, the oligotrophic KwaZulu-Natal (KZN) Bight, a data-limited system on the east coast of South Africa, was ... -
The effect of distance from clinics on maternal and child health (MCH) service utilization and MCH status.
(2004)There is strong evidence from developing countries to support the hypothesis that physical accessibility of health services, particularly absolute distance from clinics, is a major determinant of health service utilization ... -
Enhancing integrated coastal management decision making in KwaZulu-Natal, South Africa through knowledge transfer and information sharing.
(2019)Coastal environments are complex systems being sought-after for a myriad of environmental, socioeconomic and cultural activities, supporting an estimated 44% of the world’s population. The demand for coastal space and ... -
The epidemiology of malaria in Zambia.
