Assessment of roadkills in Hluhluwe-Imfolozi Park, KwaZulu-Natal, South Africa.
(2017)Anthropogenic land-use activities are considered to be the main contributor to current worldwide changes in natural ecosystems. South Africa is one of the countries that has been severely affected by changing land-use. The ... -
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 ... -
Chemokines and haematological profile in Sprague-Dawley rats infected with trichinella Zimbabwensis and Plasmodium berghei ANKA.
(2017)Trichinellosis is an important re-emerging parasitic zoonosis caused by nematode species of the genus Trichinella and Plasmodium falciparum malaria is among the leading causes of mortality and morbidity in sub-Saharan ... -
Cytokine and haemtological profiles in sprague-dawley rats experimentally infected with trichnella zimbabwensis and plasmodium berghei Anka.
(2017)Abstract available in PDF file. -
Diet preference of common mynas (Sturnus tristis) in urban areas of Pietermaritzburg and Durban, KwaZulu-Natal.
(2017)Urbanization is one of the anthropogenic land use changes with a negative impact on biodiversity generally. However, some species are persisting well in urban areas and are termed urban exploiters. One of these species is ... -
DNA barcoding of KwaZulu-Natal afromontane forest parmelia (parmeliaceae) species: a molecular approach to accurate specimen identification and sensitivity to climate change.
(2018)Accurate species identification is challenging, especially in groups with subtle taxonomically diagnostic characters such as lichens. Molecular-based techniques have shown to be a valuable tool for accurate specimen ... -
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 ... -
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 ... -
Field evaluation and characterisation of the mode of imazapyr tolerance in three mutant sugarcane genotypes.
(2016)Abstract available in PDF file. -
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 ... -
Foliar secretory cavities of Vepris lanceolata (Lam.) G. Don (Rutaceae): micromorphology and chemical composition of the secretion.
(2017)Secretory structures such as ducts, trichomes and cavities consist of cells that are primary sites synthesizing essential oils and other phytochemical compounds with medicinal properties. Little is known about the ... -
Friendly neighbours? Investigating ecological facilitation between Thunbergia atriplicifolia (Acanthaceae) and Exochaenium grande (Gentianaceae).
(2018)Wildflowers that co-exist, share similar floral signals and flower simultaneously, may interact with the same pool of pollinators, therefore sharing pollinator species and individuals. Floral similarity could be a result ... -
The functional role of birds as pollinators in southern Cape fynbos.
(2018)Nectarivorous birds, particularly sunbirds, are important pollinators of plants in the Cape Flora of South Africa, being responsible for pollinating approximately 5% of plant species. However, interactions between plants ... -
The genetic connectivity of diplodus capensis (blacktail) and neoscorpis lithophilus (stonebream) fish populations in the Southwest Indian Ocean.
(2016)Abstract available in PDF file. -
Histo-phytochemical evaluation and characterisation of the foliar structures of Tagetes minuta L. (Asteraceae).
(2018)Plants have been used as ethnomedicine for millennia. In recent years, there has been an upward surge of interest in the use of plants as medicine due to the interest in drugs with fewer side effects as well as the fight ... -
An investigation of the prerequisite conditions which enable invasion of moist grasslands by Dalbergia obovata.
(2019)Encroachment by Dalbergia obovata into moist coastal grasslands within eThekwini Municipality was identified as a potential threat to the conservation of this threatened habitat type. An investigation was undertaken to ... -
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 ... -
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 ... -
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. ...
