Character variation and a cladistic analysis of the genus Lachenalia Jacq.f. ex Murray (Hyacinthaceae:Massonieae)
Morphological variation and a cladistic analysis of the large, endemic Southern African genus Lachenalia Jacq.f. ex Murray (Hyacinthaceae: Massonieae) is presented. Its close taxonomic relationship with the small endemic ...
Storage of frequently used traditional South African medicinal plants.
The post-harvest physiology of nine frequently used indigenous southern African medicinal plants was investigated, in particular the effects of storage time and accelerated ageing on the biological activity and chemical ...
The influence of the monocarpic herb, Isoglossa woodii, on subtropical forest tree dynamics and diversity.
Dominant understorey species, such as herbs, ferns, palms and shrubs may influence forest tree species diversity and dynamics. Their influence may be through shading the forest floor, thereby affecting regeneration of ...
Pollination of Plectranthus L'Her. (Lamiaceae) along the Eastern seaboard of southern Africa.
Pollination data is provided for a third of the Plectranthus species in southern Africa. In the largest genus of Lamiaceae in the region (53 species), 18 were studied, plus two species of allied genera (Pycnostachys ...
In vitro propagation of Dierama erectum.
Dierama is a genus of plants with a potential to be developed as ornamental plants. It falls under the Iridaceae family and comprises of 44 species. Dierama erectum Hilliard, an attractive species with horticultural potential ...
The ecological implications of sea-level rise and storms for sandy beaches in KwaZulu-Natal.
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, ...
Assessment of a process-based model to predict the growth and yield of Eucalyptus grandis plantations in South Africa.
It is believed that the process-based model 3-PG (Physiological Principles Predicting Growth; Landsberg and Waring, 1997) can potentially play a useful role within South African forestry, both as an operational and a ...
The influence of root chilling on the hydraulic characteristics of selected Eucalyptus taxa.
The hydraulic conductance of a plant is a significant factor in determining the
Sugarcane stem borers in Ethiopia : ecology and phylogeography.
Eldana saccharina Walker (Lepidoptera: Pyralidae) is an indigenous insect widely distributed throughout Sub-Saharan Africa that is a major pest of sugarcane in southern Africa. Studies have shown that populations from West ...
Metabolic physiology of Colubrid dietary specialists, Dasypeltis scabra and Dasypeltis inornata.
Metabolic rate (MR) and digestive duration are thermally dependant, and energy usage changes as body temperature (Tb) changes. Increased Tb during digestion causes a rapid increase in VO2 and a shorter postprandial metabolic ...
