Abstract:
Thesis (M. Sc. (Botany)) -- University of Limpopo, 2016<br>The need to conduct a detailed biological and ecological study on Euphorbia clivicola was sparked by the drastic decline in the sizes of the Percy Fyfe Nature Reserve (Mokopane) and Radar Hill (Polokwane) populations, coupled with the discovery of two new populations; one in Dikgale and another in Makgeng village. The two newly (2012) discovered populations lacked scientific data necessary to develop an adaptive management plan.

Electron microscopy (EM) indicated that these viruses could be potyviruses, as they were flexuous particles of approximately 700 to 800 nm.

Currently, cost-effective, non-lethal solutions are lacking. From June through December 2012, I installed novel electronic scarecrows on two commercial citrus orchards and a private reserve and used video-recording remote cameras to assess cropraiders’ reactions to them in Limpopo Province, South Africa.

Coastal dolphins on the South African east coast are threatened by degradation and loss of habitat as a result of increasing coastal development, industrial effluent and agricultural runoff.

In light of the high rate of mortality and apparent depletion of both species, the persistence of bottlenose (Tursiops truncatus) and humpback (Sousa chinensis) dolphins in that region has been questioned.
