How many species of angulate tortoises occur in Southern Africa? (Testudines: Testudinidae: Chersina)
(Wiley-Blackwell, 2020)Using range-wide sampling and 1,143 bp of mtDNA (cytochrome b gene) and 14 microsatellite loci, we examined genetic differentiation in the widely distributed Southern African angulate tortoise (Chersina angulata). We found ... -
How much leaf area do insects eat? A data set of insect herbivory sampled globally with a standardized protocol
(Ecological Society of America, 2021)Herbivory is ubiquitous. Despite being a potential driver of plant distribution and performance, herbivory remains largely undocumented. Some early attempts have been made to review, globally, how much leaf area is removed ... -
How to build science-action partnerships for local land-use planning and management: Lessons from Durban, South Africa
(Resilience Alliance, 2016)The gap between scientific knowledge and implementation in the fields of biodiversity conservation, environmental management, and climate change adaptation has resulted in many calls from practitioners and academics to ... -
How to write a popular article
(SANCOR, 2008)This newsletter has criteria for the development of a popular article. -
Hydromedusae off the Orange River Mouth, Southern Africa
(NISC (Pty) Ltd and Taylor& Francis, 2003)A total of 242 zooplankton samples from the upper 100 m of the water column was collected discontinuously from March 1997 to January 1999 off the Orange River mouth on the west coast of southern Africa. Six species of ... -
Identifying global priorities for the conservation of vipers
(Elsevier, 2016)Vipers are among the most misunderstood and persecuted animals. They occupy most terrestrial ecosystems around the world, often at high population densities. However, certain aspects of their biology (e.g., low fecundity ... -
Impact of climate change and anthropogenic activities on renewable coastal resources and biodiversity in Nigeria
(Academic Journals, 2012)Climates related disaster is greatly human induced warming, leading to substantial fluctuations in earth temperature which is currently a global issue of environmental concern. Human proximity and pressure in and around ... -
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. ... -
Implementing value chain analysis to investigate drivers and sustainability of Cape Town's informal economy of wild-harvested traditional medicine
(Routledge, 2015)Despite a highly visible presence, policy-maker knowledge of the drivers and participants in the informal economy of wild-harvested medicinal plants in Cape Town remains limited. To illuminate the workings of this local ... -
Implications of the breakdown in the indigenous knowledge system for rangeland management and policy: A case study from the Eastern Cape in South Africa
(Taylor and Francis Group, 2023)Communal rangelands in South Africa are generally perceived as overgrazed owing to complexities in their histories and collective utilisation which often leads to improper management. A suitable ... -
The implications of the reclassification of South African wildlife species as farm animals
(South African Assn. For The Advancement Of Science, 2020)The Government Gazette No. 42464 dated 17 May 20191 amended Table 7 of the Animal Improvement Act (Act no. 62 of 1998), which lists breeds of animals, to include at least 32 new wild animal species, including 24 ... -
In a rough spot: Declines in Arthroleptella rugosa calling densities are explained by invasive pine trees
(Wiley, 2023)Basing conservation interventions on evidence is important for justifying their associated cost and gauging their effectiveness. For amphibians, the number of studies available to support conservation ... -
In quest of contact: phylogeography of helmeted terrapins (Pelomedusa galeata, P. subrufa sensu stricto)
(PeerJ, 2018)Based on rangewide sampling and three mitochondrial and two nuclear markers (together up to 1,850 bp and 1,840 bp, respectively), we examine the phylogeography of two helmeted terrapin species (Pelomedusa galeata and P. ... -
In silico analysis of a putative dehalogenase from the genome of halophilic bacterium Halomonas smyrnensis AAD6T
(Taylor and Francis, 2022)Microbial-assisted removal of natural or synthetic pollutants is the prevailing green, low-cost technology to treat polluted environments. However, the challenge with enzyme-assisted bioremediation is the laborious nature ... -
In vitro acetylcholinesterase inhibitory activity and chemical composition of the dichloromethane extracts of the leaves and inflorescences of the tumbleweed, Trachyandra laxa (N.E.Br.) Oberm. var. rigida (Suesseng.) Roessl
(South African Journal of Botany, 2022)Trachyandra laxa, which belongs to the family Asphodelaceae, is a poisonous geophyte, often consumed by livestock, particularly when pastures are poor. Ingestion of T. laxa by livestock causes paresis and paralysis of the ... -
Infaunal benthic communities from the inner shelf off southwestern Africa are characterised by generalist species
(Public Library Science, 2015)Infaunal communities of benthic macro-organisms ( 1mm length) were studied from 81 samples collected across nine sites to the north and south of the Orange River in the Benguela upwelling ecosystem in 2003, with a view ... -
