Biochemical and biophysical indicators of chilling tolerance in some species of Eucalyptus.
Although Eucalyptus species are indigenous to Australia, they have been successfully cultivated in South Africa, where they are mainly used in the mining and paper industries. With the explosion in these industries it ...
Biology and stock assessment of the coastal fish, Sarpa Salpa (Sparidae), off the KwaZulu-Natal coast, South Africa.
This study investigated aspects of the biology of Sarpa salpa, such as reproduction, age and growth, and mortality, which are necessary for an assessment of the status of this species off the KwaZulu-Natal (KZN) Coast. The ...
The effects of a cigarette carcinogen on glucocorticoid receptor methylation.
Small cell lung cancer (SCLC) is an aggressive disease with an extremely poor prognosis. Lung cancer has been linked to cigarette smoking. SCLCs are glucocorticoid insensitive due to reduced levels of glucocorticoid receptor ...
Altitudinal and seasonal variation in amethyst sunbird physiology.
Southern Africa is characterised by an unpredictable environment with daily and seasonal temperature fluctuations. As a local or non-migratory endothermic species occurring over an altitudinal gradient from the Drakensberg ...
Endogenous and exogenous factors involved in sorghum germination with reference to malting.
In Africa, the grain sorghum (Sorghum bicolor (L.) Moench), is malted to provide the most important ingredient in brewing, malt, which is used primarily for the production of traditional (opaque) sorghum beer. Malting ...
The impact of a sugar by-products effluent on the beach Meiofauna at Sezela Beach, KwaZulu-Natal, South Africa
Beach meiofauna were chosen as environmental indicators to investigate the impact of Illovo sugar by-products effluent. The effluent is pumped through a 20 cm diameter pipeline into surf zone at Sezela beach on the coast ...
Experience of EIA follow up in Lesotho.
Environmental Impact Assessment (El A) is a process that is widely practised as it assists in decision-making and also helps to overcome the environmental problems that could result from development activities. However, ...

Micropropagation and in vitro studies of Pinus patula Scheide et Deppe.
For the South African forestry industry, the patula pine (Pinus patula) is the most commercially important softwood species. A pine clonal programme has yet to be fully implemented in this country and at present much effort ...
Comparative water relations of Protea nitida seedlings and sprouters after fire.
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 ...
