The biology, ecology and conservation of four Flufftail species, Sarothrura (Aves: Rallidae)
The distribution, status, biology and ecology of four flufftail species were investigated in South Africa and Zimbabwe. The Redchested Flufftail is a successful and widely distributed species, occupying a wide range of ...
In vitro propagation of Scilla natalensis planch.
In South Africa, large quantities of Scilla natalensis are harvested from wild populations and sold as traditional medicine, which is reducing the density, distribution and genetic diversity of wild populations. The ...
Spatial modelling of fire dynamics in Savanna ecosystems.
Fire is used in the management of ecosystems worldwide because it is a relatively inexpensive means of manipulating thousands of hectares of vegetation. Deciding how, where and when to apply fire depends primarily on the ...
The use of a virtual world to address misconceptions held by students regarding photosynthesis and respiration.
In an effort to contribute to the improvement of Matric Biology education, a survey was conducted in 1996 and 1997 of Matric pupils and first year students at several tertiary institutions, in order to identify those topics ...
A study of some of the inter-relationships between maize and the seed storage fungi as typified by Aspergillus flavus var. columnaris.
The seed storage fungi (xerotolerant) species of the genera Aspergillus and Penicillium} are renowned for their devastating effects on stored grain and grain products. In view of the fact that most of these fungi Iiberate ...
High temperature fatigue crack growth behaviour of TIMETAL 21S in an oxidizing environment.
The high temperature fatigue crack growth behaviour of the newly developed, metastable titanium-based alloy, TIMETAL 21S, was investigated in an inert and an oxidizing environment. The investigation adopted a two pronged ...
An evaluation of the periglacial morphology in the high Drakensberg and associated environmental implications.
Although periglacial research in the high Drakensberg and Lesotho mountains has received growing interest amongst southern African geomorphologists, little detailed, quantitative information was available prior to this ...
