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 ... -
Initial evaluation of the care and rehabilitation success of Cape Cormorants Phalacrocorax capensis rescued from Robben and Jutten islands, South Africa, in January 2021
(Taylor and Francis Group, 2023)The population of the endangered Cape Cormorant Phalacrocorax capensis more than halved over the last three decades (BirdLife International 2018a). In January 2021, nearly 2 000 Cape Cormorant chicks were ... -
An insight into the reproductive biology of the bearded goby Sufflogobius bibarbatus
(Wiley, 2013)Preliminary results obtained from histological analyses of the male reproductive organs, supplemented with field and behavioural data, indicate that Sufflogobius bibarbatus, a small, slow growing gobiid exhibiting low ... -
Intercolony variation in reproductive skipping in the African penguin
(Wiley Open Access, 2022)In long-lived species, reproductive skipping is a common strategy whereby sexually mature animals skip a breeding season, potentially reducing population growth. This may be an adaptive decision to protect survival, or ... -
Is penguin circovirus circulating only in the antarctic circle? Lack of viral detection in namibia
(MDPI, 2023)The known host range of circoviruses is continuously expanding because of more intensive diagnostic activities and advanced sequencing tools. Recently, a new circovirus (penguin circovirus (PenCV)) was identified in the ... -
Is your garden green? How to be kind to your garden
(Botanical Society of South Africa, 2008)Years ago, there was plenty of open, natural veld surrounding our towns and it was rich in wildlife. As towns expanded the natural veld and wildlife shrank into patches between towns, factories and farm land. With this ... -
Iterative mapping of marine ecosystems for spatial status assessment, prioritization, and decision support
(Frontiers Media, 2023)South Africa has taken an iterative approach to marine ecosystem mapping over 18 years that has provided a valuable foundation for ecosystem assessment, planning and decision-making, supporting improved ecosystem-based ... -
Jellyfication of marine ecosystems as a likely consequence of overfishing small pelagic fishes: Lessons from the Benguela
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 2013)Changes in two contrasting ecosystems of the Benguela upwelling region, one dominated at mid-trophic level by jellyfishes (Namibia, northern Benguela ecosystem, where small pelagic fish abundance has been severely depleted) ... -
Kelp forests: forests of a different kind
(Botanical Society of South Africa, 2011)The United Nations (UN) Food and Agriculture Organization (FAO) defines a forest as being 'more than 0.5 ha with trees higher than 5 m and a canopy cover of more than 10%, or trees able to reach these thresholds in situ', ... -
Lasiosiphon rigidus, a new species from the Tankwa Karoo and two new combinations in the genus for South Africa
(MDPI, 2013)Thymelaeaceae are well represented in southern Africa, with ± 190 species in nine genera (Bredenkamp & Beyers 2000; Beaumont et al. 2009). Preliminary phylogenetic analyses of nuclear and plastid DNA sequences (Van der ... -
Legume phylogeny and classification in the 21st century: Progress, prospects and lessons for other species-rich clades
(Botanischer Garten und Botanisches Museum, 2013)The Leguminosae, the third-largest angiosperm family, has a global distribution and high ecological and economic importance. We examine how the legume systematic research community might join forces to produce a comprehensive ... -
Leopards and mesopredators as indicators of mammalian species richness across diverse landscapes of South Africa
(Elsevier, 2021)The rapid extinction of species over the past few decades has created a biodiversity crisis. Factors contributing to recent extirpations are linked to increased human population growth, habitat loss and fragmentation, and ... -
Leptophytum foveatum Chamberlain & Keats (Rhodophyta, Corallinales) retaliates against overgrowth by other encrusting algae
(Elsevier, 1994)The encrusting coralline alga, Leptophytum foveatum, is the most abundant crustose alga in the lower eulittoral zone at Yzerfontein and other exposed sites on the West Coast of South Africa. The surface of this species is ... -
Life at the margins of the continents: an examination of the intertidal marine life of the south Western Cape
