Evolution of the Satyrium longicauda (Orchidaceae) species complex.
(2021)The identification of morphological variation in taxa grouped within a species complex is fundamental not only in systematics, but plays an important role in evolutionary biology as well. Finding diagnostic characters ... -
A herpetofaunal survey of Swaziland.
(1992)The present report, based on a survey conducted over four years and on the accumulation of museum records, provides the most detailed documentation yet of the herpetofauna of Swaziland. One hundred and two new forms are ... -
An avifaunal study of Pigeon Valley Park as a biogeographic island in an urban area with special reference to the Natal Robin (Cossypha natalensis Smith)
(1992)Pigeon Valley Park, on Durban's Berea Ridge, is an approximately 10-ha remnant of coastal forest, which is totally surrounded by suburban housing and roads. As such it is ideal as a study area for investigating the ... -
Animal model studies on the antelope schistosomes, Schistosoma margrebowiei and S. leiperi, with particular reference to their proposed role in limiting the distribution of human intestinal schistosomiasis.
(1992)It has been postulated that the absence of human and cattle schistosomiasis in parts of southern Africa where lechwe antelope (Kobus leche) occur is a consequence of an immunologically-mediated protection induced by repeated ... -
The herpetofauna of the Orange Free State : with special emphasis on biogeographical patterning.
(1992)The taxonomic status, distribution and ecology of the herpetofauna of the Orange Free State are discussed, based on the examination of 10 096 specimens housed in various southern African museums. The majority of specimens ... -
Experience of EIA follow up in Lesotho.
(2003)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, ... -
Development of explants potentially suitable for cryopreservation of the recalcitrant-seeded species Theobroma cacao L. and Barringtonia racemosa (L.) roxb.
(2008)The two species investigated in this study were Theobroma cacao and Barringtonia racemosa. Theobroma cacao has worldwide economic importance, as cocoa (the main ingredient in chocolate) is produced from the seeds of this ... -
Altitudinal and seasonal variation in amethyst sunbird physiology.
(2007)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 ... -
The impact of a sugar by-products effluent on the beach Meiofauna at Sezela Beach, KwaZulu-Natal, South Africa
(2007)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 ...
