In vitro culture and genetic transformation of selected ancestral and commercial sugarcane germplasm.
(2013-11-25)
Sugarcane is an economically important crop and its high demand has necessitated the use of biotechnology methods to produce and accelerate the production of desirable genotypes. One such method is genetic transformation. ...
Spatial and reproductive ecology and population status of the Nile crocodile (Crocodylus niloticus) in the Lake St Lucia estuarine system, South Africa.
(2014)
The Lake St Lucia estuarine system, Africa’s largest and oldest protected estuary, also contains the largest Nile Crocodile (Crocodylus niloticus) population in a single waterbody in South Africa. We investigated the ...
Propagation of Coleonema album (Thunb.) Bartl. & J. C. Wendl. : a horticultural and medicinal plant.
(2013-11-06)
Coleonema album is a South African green treasure, endemic to the Cape region and hard to find in other parts of the country. It is ranked among the most highly utilized medicinal plants at present. The plant extracts ...
Key factors driving the foraging ecology of Oribi : fear, cattle and the quality and quantity of food.
(2015)
Body size and digestive physiology are two factors that influence herbivores foraging behaviour, habitat use and potential to compete with other animals. The aim of this study was to determine how seasonal changes in grass ...
Fast life in the slow lane : life history and energetics of a basal placental mammal Setifer setosus (Schreber, 1778).
(2014-08-28)
There is increasing evidence that homeothermy (the maintenance of a high and stable body temperature-Tb) as observed in modern mammals was derived from an ancestral heterothermic (flexible Tb regulation) state. One of main ...
Studies on factors influencing viability after cryopreservation of excised zygotic embryos from recalcitrant seeds of two amaryllid species.
(2010)
Recalcitrant unlike orthodox seeds do not show a sharp border between maturation and germination
and remain highly hydrated and desiccation-sensitive at all developmental and post-harvest
stages. In contrast with ...
Do herbivores facilitate seed germination and seedling recruitment of woody plants?.
(2014-09-02)
Woody plant encroachment is a phenomenon whereby trees and shrubs invade grasslands or increase in an already wooded area, resulting in lower yields of herbaceous plants and a reduction in the carrying capacity of rangelands. ...
The effect of land use on the species composition of amphibians in North Eastern KwaZulu-Natal.
(2010)
Global declines in amphibian species have directed research towards investigating why this is happening. One of the major causes of these declines is the fragmentation and loss of habitat. This study examined the effect ...
The role of meta-topolins on the physiology of micropropagated 'Williams' bananas (Musa spp. AAA)
(2012)
Banana production ranks fifth behind cereals as a food crop and has potential, along with other major crops, to feed the world's increasing population. Globally, continuous efforts and techniques including the use of plant ...
South African medicinal orchids : a pharmacological and phytochemical evaluation.
(2012)
The Orchidaceae makes up the largest and most diverse family of flowering plants. Orchids are popular, often expensive ornamentals, with a broad range of ethnobotanical applications. There is very limited documented ...
