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 ... -
Taxonomic revision of the Memecylon natalense species-complex in southern Africa.
(2018)iv ABSTRACT Two Memecylon species (M. natalense and M. bachmannii) were previously recognized in southern Africa, and three species of M. section Buxifolia as occurring in Mozambique (M. natalense, M. torrei and M. ... -
The micromorphological characterization, histo-phytochemical analysis and bioactivity of Tabernaemontana ventricosa hochst. ex a. dc. (Apocynaceae).
(2018)Therapeutic plants are universally important due to their healing properties and pharmacological effects. Tabernaemontana ventricosa is curative plant belonging to the Apocynaceae. The bark, stem, leaves and latex of T. ... -
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 ... -
A revision of the taxonomy and phylogenetic background of the South African genus Kazimierzus Plisko, 2006 (Oligochaeta: Kazimierzidae)
(2018)Species identity and distribution information is important in conservation and monitoring of biodiversity. Megadrile fauna is very diverse in Southern Africa with most of the fauna demonstrating high levels of endemism, ... -
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 ... -
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 ... -
Utilization of dried blood spots for assessing Dusky kob (Argyrosomus japonicus) glycaemia and metabolome in South African aquaculture.
(2018)Dusky kob (Argyrosomus japonicus) is an important marine fish in South African aquaculture, and has the potential to become commercially significant. The continuous growth of Dusky kob culture faces challenges with regards ... -
Screening, selection and clonal propagation of Amaranthus dubius genotypes with different calcium and iron content.
(2018)Decontamination of Amaranthus dubius field-derived nodal explants was achieved in a 10 min soak with 1% (v/v) NaOCl and 2 drops of Tween 20® followed by three rinses in sterile distilled water, immersion in an antibiotic ... -
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 ... -
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 ... -
Effects of antifungul treatments on some recalcitrant seeds.
(2017)Recalcitrant seeds cannot be stored under normal storage conditions and are characterized by not undergoing dehydration, sensitivity to desiccation, high susceptibility to desiccation injury, and the fact that they are ... -
Small mammal responses to Scarp Forest Restoration in the Maputoland-Pondoland-Albany Hotspot, South Africa.
(2017)Restoration ecology is a relatively new field. Although a range of attributes have been used to assess restoration success, they have not been standardised across studies. Recently, three main ecological attributes have ... -
Ciliate-zooplankton epibiosis in Lake St Lucia.
(2018)Epibiosis is a symbiotic association of two organisms in which one species (epibiont) uses the surface of another species (basibiont or host) as an attachment substrate. An increasing number of studies are revealing that ... -
The potential use of embryonic shoot apices as explants for cryopreservation of selected recalcitrant-seeded species.
(2017)Seeds can belong to two major categories, viz., orthodox or recalcitrant. Recalcitrant seeds are desiccation, and often, chilling sensitive and thus cannot be stored for any meaningful time using conventional methods. ... -
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 ... -
Selection and micropropagation of solanum nigrum genotypes with varying calcium and iron content.
(2018)A direct organogenesis protocol was established for Solanum nigrum using leaf explants from seedling plants. The post acclimatisation yield of the seedling-derived leaf explants was 25 plants/explant. It included decontaminating ... -
