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 ... -
A genetic approach to the biodiversity of shallow water alcyonacea in South Africa.
(2018)The cnidarian order Alcyonacea (Octocorallia) represents a diverse group of marine invertebrates that are dominant taxa on shallow and deep reefs. These organisms constitute sensitive indicators of climate change and ... -
The genetic connectivity of diplodus capensis (blacktail) and neoscorpis lithophilus (stonebream) fish populations in the Southwest Indian Ocean.
(2016)Abstract available in PDF file. -
Grape fruit juice improves glycemic index and up-regulates expression of hepatic organic cation transporter protein (OCTI) in the rat
(2009-03)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 ... -
House Crow (Corvus splendens) eradication measures from eThekwini Municipality, KwaZulu-Natal, South Africa.
(2018)Abstract available in PDF file. -
Impacts of anthropogenic disturbance on persistence patterns of forest mammals in an urban-forest mosaic of eThekwini Municipality, Durban, South Africa.
(2018)The burgeoning human population size and the consequent land development pressures to meet its various needs has led to an unparalleled increase in the rates at which natural environments are converted for anthropogenic ... -
An investigation into the protein requirement of a marine prawn Fenneropenaeus indicus (H. Milne Edwards)
Abstract available in PDF file. -
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. ... -
Medicinal properties and micromorphology of Rauvolfia caffra Sond.
(2017)Medicinal plants are effective treatments for various ailments and conditions due to the fact that they are easily accessible, cost effective, trusted and have little to no side effects. Plants produce bioactive or secondary ... -
Melanisation of lichens : the composition of melanin and the role of ultraviolet light (uv) in peltigeralean and non-peltigeralean lichens.
(2017)Lichens are unique organisms widely known for their ability to tolerate extreme environmental conditions due to the symbiotic relationship between a fungus and algae or cyanobacteria. This includes the ability to synthesise ...
