Impacts of an invasive alien Proteaceae on native plant species richness and vegetation structure
(South African Journal of Botany, 2021)The influence of invasive alien plants on plant community structure and above ground biomass in their novel range is poorly understood, as the magnitude and direction of these effects are often species and ecosystem specific. ... -
Gyrodactylus molweni sp. n. (Monogenea: Gyrodactylidae) from Chelon richardsonii (Smith, 1846) (Mugilidae) from Table Bay, South Africa
(Elsevier, 2021)Gyrodactylus molweni sp. n. is described from the body surface and fins of the South African mullet, Chelon richardsonii (Smith, 1846) collected from Table Bay Harbour, Cape Town and is compared to five other Gyrodactylus ... -
ROV assessment of mesophotic fish and associated habitats across the continental shelf of the Amathole region
(Nature Research, 2021)Understanding how fsh associate with habitats across marine landscapes is crucial to developing efective marine spatial planning (MSP) in an expanding and diversifying ocean economy. Globally, anthropogenic pressures ... -
Opportunities for improving recognition of coastal wetlands in global ecosystem assessment frameworks
(Elsevier, 2021)Vegetated coastal wetlands, including seagrass, saltmarsh and mangroves, are threatened globally, yet the need to avert these losses is poorly recognized in international policy, such as in the Convention on Biological ... -
Austral winter marine epilithic diatoms: Community composition and distribution on intertidal rocky substrate around the coast of South Africa
(Elsevier, 2020)The knowledge on the composition and spatial distribution of marine benthic diatoms around the coast of South Africa remains limited. Epilithic diatom assemblages from natural intertidal rocky substrate and physico-chemical ... -
Climatic and topographic changes since the Miocene influenced the diversification and biogeography of the tent tortoise (Psammobates tentorius) species complex in Southern Africa
(BMC, 2020)Background: Climatic and topographic changes function as key drivers in shaping genetic structure and cladogenic radiation in many organisms. Southern Africa has an exceptionally diverse tortoise fauna, harbouring one-third ... -
Codon-based analysis of selection pressure and genetic structure in the Psammobates tentorius (Bell, 1828) species complex, and phylogeny inferred from both codons and amino acid sequences
(John Wiley & Sons, 2021)This study used codon analysis (dN/dS and Tv/Ti) to investigate selection pressure and genetic structure in the highly polymorphic Psammobates tentorius species complex, and amino acid sequences to construct a phylogeny ... -
A novel approach to quantify metrics of upwelling intensity, frequency, and duration
(Public Library of Science, 2021)The importance of coastal upwelling systems is widely recognized. However, several aspects of the current and future behaviors of these systems remain uncertain. Fluctuations in temperature because of anthropogenic climate ... -
Exogenous antioxidants enhance seedling growth and yield of artificially aged cabbage and lettuce seeds
(MPDI, 2021)Aged seeds exhibit compromised vigour in terms of germination, seedling emergence and growth, but this can to some extent be alleviated by invigoration treatments before sowing. This study aimed to investigate ageing ... -
Specialized morphology, not relatively large head size, facilitates competition between a small-bodied specialist and large-bodied generalist competitors
(Journal of Zoology, 2021)Interspecific competition for limited resources should theoretically occur between species that are morphologically similar to each other. Consequently, species that reduce competition by adapting to specialize on a specific ... -
The effects of detergent and fertilizer toxicity on growth rate, nutrient utilization and survival of Clarias gariepinus (Burchell) fingerlings reared under controlled condition
(International Journal of Fisheries and Aquatic Studies, 2020)Study on the effects of metals on growth rate and survival of Clarias gariepinus (Burchell 1822) fingerlings bred in tanks containing water concentrated with inorganic fertilizer and detergent was conducted. 300 fingerlings ... -
Sampling bias in reptile occurrence data for the Kruger National Park
(AOSIS, 2020)To effectively conserve and manage species, it is important to (1) understand how they are spatially distributed across the globe at both broad and fine spatial resolutions and (2) elucidate the determinants of these ... -
Topography-derived variables provide insight into habitat occupancy of a cryptic snake, Bitis atropos
(Wiley, 2021)Understanding species’ habitat use is fundamental for conservation and management. However, quantifying habitat use for small cryptic species is limited by imperfect detection during field surveys and the lack of habitat ... -
Wildlife- friendly livestock management promotes mammalian biodiversity recovery on a semi-arid Karoo farm in South Africa
(Frontiers Media, 2021)Agriculture is an essential production system used to feed the growing human population, but at the same time has become a major driver of biodiversity loss and environmental degradation. Employing production methods that ... -
Variation and change of upwelling dynamics detected in the world's eastern boundary upwelling systems
(Frontiers Media, 2021)Global increases in temperature are altering land-sea temperature gradients. Bakun (1990) hypothesized that changes within these gradients will directly affect atmospheric pressure cells associated with the development of ... -
Transfer of Madagascan species of Gnidia L. to Lasiosiphon Fresen. (Thymelaeaceae: Thymelaeoideae)
(South African Journal of Botany, 2017)Thirteen of the fourteen Malagasy species of Gnidia are transferred to Lasiosiphon following its re-instatement based on systematic studies of the Thymelaeoideae. New combinations are made for five of the species and the ... -
Tortoise forensics: Conservation genetics of the leopard tortoise Stigmochelys pardalis in Southern Africa
(Salamandra, 2021)Sub-Saharan Africa harbours an outstanding diversity of tortoises of which the leopard tortoise Stigmochelys pardalis is the most widespread. Across its’ range the species is impacted by habitat transformation, over-collection ... -
Neuroprotective activities of crossyne flava bulbs and amaryllidaceae alkaloids: Implications for parkinson’s disease
(Molecules, 2021)Parkinson’s disease (PD) is one of the most common neurodegenerative diseases and affects approximately 6.3 million people worldwide. To date, the treatment of PD remains a challenge, as available treatment options are ... -
