(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. ... -
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 ... -
Molecular identification of hookworm isolates from stray dogs, humans and selected wildlife from KwaZulu-Natal and Mpumalanga provinces of South Africa.
(2019)Hookworms are nematodes that cause infections to the host via skin penetration of the third stage larvae and they are widely distributed in the tropical and subtropical regions. They parasitize a wide range of host species ... -
More than just food : mussels as biomonitors of microplastic pollution in the KwaZulu-Natal coastal environment.
(2017)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. -
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 ... -
Potential neurological effects in banana bats foraging at wastewater treatment works.
(2016)Abstract available in PDF file. -
The potential use embryonic shoot apices as explants for cryopreservation of selected recalcitrant-seeded species.
(2017)Abstract available in PDF file. -
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 ... -
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 ... -
Production of hydroxyl radicals by lichens via extracellular hydroquinone-driven redox cycling.
(2016)Abstract available in PDF file. -
A re-appraisal of the holothuroid genera Pseudocnus Panning, 1949 and Pseudocnella Thandar, 1987 based on morphological and, for the latter, also molecular evidence (Echinodermata : Holothuroidea : Dendrochirotida : Cucumariidae)
After the erection of the genus Pseudocnella by Thandar (1987) to accommodate three southern African Cucumariids and a Mediterranean form, then classified in Pseudocnus, certain problems still remained. In addition to this ... -
