The financial and economic feasibility of biodigester use and biogas production for rural households.
(2011)In South Africa, sustainable development is set in the context of two separate economies. The second of these economies consists of the rural population and is characterised by poverty and stagnant development. Sustainable ... -
A phylogeny of South African east coast intertidal rocky-shore Polychaete worms (Annelida) and the genetic structure and demographic history of an example, Marphysa corallina.
(2015)The Annelida is an evolutionarily ancient invertebrate taxon. Recent studies have found that the formerly described sister taxon of the Polychaeta, Clitellata, is a derived Polychaete group thus making Polychaeta a ... -
Efficacy of maslinic acid and chloroquine on the co-infection of Plasmodium berghei and Trichinella zimbabwensis in Sprague-Dawley rats.
(2015)Many people living in Africa and elsewhere in the tropics suffer from combined malaria, soil-transmitted infections and tissue-dwelling nematodes. Most of these deaths are prevalent in sub-Saharan Africa (SSA) where the ... -
Prevalence and genetic relatedness of Besnoitia besnoiti isolates from different geographical regions of South Africa.
(2015)Bovine besnoitiosis is a protozoan disease caused by an apicomplexan parasite Besnoitia besnoiti and is reportedly re-emerging in Europe and occurring in many other countries including South Africa. The disease has long ... -
The leaf secretory apparatus of Hibiscus surattensis and Hibiscus sabdariffa (Malvaceae) : micromorphology, histo-phytochemistry and ultrastructure.
(2015)The research presented here forms the basis of the ethnobotanical and ethnopharmacological evaluation of Hibiscus surattensis, which is a widely distributed vegetable and medicinal shrub used by African and Indian traditional ... -
A systematic study of the genus rhoicissus planch, (vitaceae) in KwaZulu-Natal.
(2015)The family Vitaceae, sometimes referred to as the grape family, comprises about 700 to 800 species and 13 to 14 genera, which includes Rhoicissus Planch. Rhoicissus contains 12 species all of which are described as climbing ... -
Mapping the expression of key functional genes associated with murine corneal endothelial development.
(2015)The cornea is a complex, layered, transparent structure that is responsible for transmitting and refracting light to ensure vision. Of all the layers, the corneal endothelium is physiologically the most important layer. ... -
Lichen photobiology in relation to climate change : protection in peltigeralean lichens against excess ultraviolet (UV) radiation using induced melanins and the effects of UV on melanin synthesizing enzymes.
(2015)Depletion of the stratospheric ozone has allowed more solar ultraviolet (UV) radiation (100-400 nm) to reach the lower atmosphere. Despite the success of the continued implementation of Montreal protocol of 1987 and its ... -
Behavioural responses of rodents to the scent and taste of compounds associated with sugar and protein degradation : implications for the evolution of chemical signals in rodent-pollinated flowers.
(2015)Volatile compounds in nectar may influence the behavioural responses of animal flower visitors, and thus have fitness consequences for both animal and plant mutualists. Rodents may use certain volatiles associated with ... -
The emission of volatile organic compounds (VOCs) from rotting fruits and wilting flowers.
(2015)Plants and the microbes that feed on them produce a high diversity of volatile organic compounds (VOCs) that often mediate interspecies communication with other organisms. Two main functions of VOCs emitted by plants are ... -
Technique establishment for in vitro selection of drought tolerant sugercane genotypes.
(2015)There is a need to have constant supply of sugarcane varieties adapted to different South African regions. However, the genetic improvement and selection of sugarcane cultivars with superior traits, e.g. drought tolerance, ... -
Water stress effects on growth, development, resource capture and resource use efficiency of two contrasting sugarcane genotypes.
(2014)Abstract available in PDF file. -
The role of floral and fruit scent compounds as mosquito attractants : developing new methods for monitoring mosquito populations.
(2016)Abstract available in PDF file. -
Patterns and influencing factors of the larval fish assemblage of the KwaZulu-Natal Bight, South Africa.
(2016)Abstract available in PDF file. -
The utility of Brachylaena discolor as a bioindicator of air pollution within selected industrial areas in KwaZulu-Natal.
(2016)The negative impacts of air pollution have made monitoring of air quality increasingly important. This is primarily true for industrial areas such as the South Durban Basin (SDB) within the eThekwini Municipal Area (EMA), ... -
The utility of Trichilia dregeana leaves as a bioindicator of air pollution within selected industrial areas in the eThekwini Municipality, South Africa.
(2016)Increased anthropogenic activities worldwide have led to dangerously high levels of gaseous emissions. Air pollution levels within industrial areas in South Africa, such as South Durban Basin (SDB), are monitored daily at ... -
Prevalence of gastro-intestinal parasites of livestock and dogs and risk factors for transmission with emphasis on giardia and cryptosporidium in Magude district, Maputo province, Mozambique.
(2016)The main objective of this study was to determine the prevalence of gastrointestinal parasites and risk factors for transmission of Giardia and Cryptosporidium in livestock and dogs of Magude District, Maputo, Mozambique ... -
