Back analysis of an ancient rockslide at Lake Fundudzi, Limpopo Province, South Africa.
(2015)A massive rockslide event occurred in the Soutpansberg Mountains of the Limpopo province approximately twenty thousand years ago that blocked the course of the eastern flowing Mutale River forming Lake Fundudzi, which ... -
Balancing agricultural and ecological needs : biodiversity, land use and ecosystem services in the Koedoes River Catchment, Limpopo.
(2015)A major topic in natural science research is land degradation and unwise land use resulting in biodiversity loss and impact negatively on ecosystem functioning. In addition, an increasing human population trend leads to ... -
Balancing water for food and environment : hydrological determinants across scales in the Thukela River Basin.
(2008)In this study, geophysical measurements (Electrical Resistivity Tomography-ERT) and remote sensing techniques were applied in the Thukela river basin at various scales to complement the classical hydrometeorological ... -
Bambara groundnut response to controlled environment and planting date associated water stress.
(2011)Bambara groundnut is a protein-rich legume, with food security potential in drought-prone regions. It has been grown for many centuries and has remained an important crop to most African subsistence farmers. However, despite ... -
Banana (Musa AAA; Cavendish sub-group) cultivar/density trials in three bioclimatic groups on the north coast of KwaZulu-Natal.
(1997)The North Coast of KwaZulu-Natal is a relatively new banana production area, for which there is an absence of local norms, specifically for choice of cultivar and population density. Three cooperative split-plot banana ... -
The bathymetry, sedimentology and seismic stratigraphy of Lake Sibaya- Northern KwaZulu-Natal.
(1998)The morphology of Lake Sibaya is a product of an ancient fluvial system that drained a coastal landscape dominated by aeolian processes. The sedimentary processes within the lake are driven by wind generated currents. ... -
Behaviour, physiological responses, meat yield and gut morphology of free-range chickens raised in a hot environment.
(2016)It is vital to minimise thermal stress and associated welfare problems for birds reared in hot environments and behaviour is a good indicator of thermal stress. The broad objective of the study was to investigate behavioural, ... -
Best institutional practices for farmworker and community equity-sharing schemes in South Africa.
(2003)Farmworker equity-share schemes were initiated by the private sector in the Western Cape region of South Africa in the early 1990's as a method of redistributing farm assets to land reform beneficiaries while maintaining ... -
The biochemical basis of colour as an aesthetic quality in Citrus sinensis.
(2001)The development of fruit colour in the sweet orange (Citrus sinensis) is a cultivar characteristic affected by climate and environment. Although external colour is not always an indication of internal quality or maturity, ... -
Biocontrol of three fusarial diseases.
(2004)Over the past one hundred years, research has repeatedly demonstrated that phylogenetically diverse microorganisms can act as natural antagonists of various plant pathogens. Interest in biological control research continues ... -
Biodiversity conservation and rural livelihoods : a comparative study of selected conservation approaches in Zimbabwe.
(2014)Historically, protected areas have operated as islands of biodiversity conservation in isolation from nearby communities. There is, however, a growing consensus that for protected areas to be more effective in conserving ... -
Biodiversity criteria and indicators for the sustainable management of industrial plantations.
(1999)Abstract not available. -
The biogeography and ecology of the secondary marine arthropods of Southern Africa.
Abstract available in PDF file. -
Biological and economic response of laying hens to dietary isoleucine, methionine, lysine and energy.
(1980)No abstract available. -
Biological and economic response of laying hens to dietary lysine and energy contents during peak and late production periods.
(2001)The effect of dietary energy and amino acid contents during the peak of production of laying hens has been well investigated, but little is known about the late production period. In most of the previous studies the focus ... -
The biological and economic responses of growing pigs to nutrient density.
(1999)No abstract available. -
Biological and molecular characterization of South African bacteriophages infective against Staphylococcus aureus subsp. aureus Rosenbach 1884, casual agent of bovine mastitis.
(2012)Bacteriophage therapy has been exploited for the control of bacterial diseases in fauna, flora and humans. However, the advent of antibiotic therapy lead to a cessation of most phage research. Recently, the problem of ... -
Biological control and plant growth promotion by selected trichoderma and Bacillus species.
(2005)Various Trichoderma and Bacillus spp. have been documented as being antagonistic to a wide range of soilborne plant pathogens, as well as being plant growth stimulants. Successes in biological control and plant growth ... -
Biological control of fusarium wilt of pine seedlings using endophytic microorganisms and silicon.
(2015)Globally, pitch canker fungus (Fusarium circinatum) poses a serious threat to the softwood forest industry. In South Africa, F. circinatum has characteristically been a nursery pathogen, causing a seedling wilt, and has ... -
Biological control of gastrointestinal nematodes of small ruminants, using Bacillus thuringiensis (Berliner) and Clonostachys rosea (Schroers).
(2011)Gastrointestinal nematode parasites cause great losses in the production of small ruminants through reduced productivity and the cost of preventive and curative treatments. Because of the threat of anthelmintic resistance, ...
