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 ... -
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. ... -
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 ... -
Marine seismic surveys for hydrocarbon exploration: What’s at stake?
(Academy of Science of South Africa, 2022)With a coastline extending approximately 3900 km, South Africa exercises jurisdiction over a vast Exclusive Economic Zone (EEZ) that exceeds 1.5 million km2 . 1 South Africa is located at an ecologically important ... -
Metabarcoding of zooplankton to derive indicators of pelagic ecosystem status
(Academy of Science of South Africa, 2022)Zooplankton play a key role in marine food webs and carbon cycling and are useful indicators of climate-related changes and ocean health in pelagic ecosystems. Zooplankton are traditionally identified to species through ... -
Observations on euphausiid communities of the south coast of South Africa
(NISC (Pty) Ltd and Taylor& Francis, 1995)A total of 24 species of euphausiid was collected during a survey along the South African south coast during January 1992. Communities over the Agulhas Bank were of low diversity and abundance and were dominated by Nycliphanes ... -
Phylogeographic investigation of the bladder grasshopper Bullacris unicolor (Orthoptera Pneumoroidea) in South Africa
(Taylor and Francis Group, 2023)There are several factors, such as genetic drift, gene flow and migration that affect the population genetic structure and phylogeographic distribution of genetic lineages within single species. Previous studies of the ... -
Renosterveld conservation in South Africa: A case study for handling uncertainty in knowledge-based neural networks for environmental management
(International Society for Environmental Information Sciences, 2009)This work presents an artificial intelligence method for the development of decision support systems for environmental management and demonstrates its strengths using an example from the domain of biodiversity and ... -
Salinity of irrigation water in the Philippi farming area of the Cape Flats, Cape Town, South Africa
(Water Research Commission, 2013)This paper explores the nature, source and spatial variation of the salinity of water used for irrigation in a coastal urban farming area in Cape Town, South Africa, where water from the Cape Flats aquifer is drawn into ... -
Self-maintaining or continuously refreshed? The genetic structure of Euphausia lucens populations in the Benguela upwelling ecosystem
(Oxford University Press, 2013)Populations of Euphausia lucens over the shelf of the southern Benguela upwelling region could be self-maintaining. Alternatively, they could be continually refreshed by expatriates from the SWAtlantic that enter the ... -
South African seaweed aquaculture: A sustainable development example for other African coastal countries
(Academic Journals, 2013)The green seaweed Ulva is one of South Africa's most important aquaculture products, constituting an important feed source particularly for abalone (Haliotis midae L.), and utilized as a bioremediation tool and other ... -
Synarthrophyton papillatum sp. nov.: a new species of non-geniculate coralline algae (Rhodophyta, Corallinales, Hapalidiaceae) from South Africa and Namibia
(Elsevier, 2008)Polychaete worm tubes within the mid to lower intertidal zone along the South African west coast were frequently observed to be overgrown by a minutely papillate species of encrusting coralline algae. Analysis of the ... -
Taxonomic studies of the genus Rhynchosia Lour. (Phaseoleae, Fabaceae) in South Africa: A review of section Chrysoscias
(Elsevier, 2018)BACKGROUND: A taxonomic study of the genus Rhynchosia section Chrysoscias is presented. The section (as classified by Baker) comprises five taxa (four species and one variety). Previous revisions of the section by various ... -
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 ... -
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 ... -
Towards characterising microplastic abundance, typology and retention in mangrove-dominated estuaries
(MPDI, 2020)Plastic and, particularly, microplastic (MP) pollution is a growing research theme, dedicated largely to marine systems. Occurring at the land–sea interface, estuarine habitats such as mangroves are at risk of plastic ... -
