African rangelands and pastoralism in a changing continent: Perspectives and opportunities
(Taylor and Francis Group, 2023)Eighty-five years ago, Africa was described as a land of promise because it provided an immense opportunity for maximum return in the minimum time (Olaniyan 2000). It was treated this way because ... -
Biomass partitioning in an endemic southern African salt marsh species Salicornia tegetaria (Chenopodiaceae)
(Taylor and Francis Group, 2020)The below ground biomass of salt marsh species accounts for more than half of the total plant biomass in salt marsh systems, yet no biomass data exist for salt marsh species in South Africa. ... -
A blueprint for integrating scientific approaches and international communities to assess basin-wide ocean ecosystem status
(Nature Research, 2023)Ocean ecosystems are at the forefront of the climate and biodiversity crises, yet we lack a unified approach to assess their state and inform sustainable policies. This blueprint is designed around research capabilities ... -
Camp Lwandle: Rehabilitating a migrant labour hostel at the seaside
(Routledge Taylor Francis Group, 2013)In southern African narratives of migrant labour, hostels and compounds are represented as typical examples of colonial and apartheid planning. Visual and spatial comparisons are consistently made between the regulatory ... -
Climate change in coastal waters: Time series properties affecting trend estimation
(AMS, 2016)In South Africa, 129 in situ temperature time series of up to 43 years are used for investigations of the thermal characteristics of coastal seawater. They are collected with handheld thermometers or underwater temperature ... -
Comparing community structure on shells of the abalone Haliotis midae and adjacent rock: implications for biodiversity
(Springer Verlag, 2013)This paper concerns the effects on biodiversity of depletion 24 of the South African abalone Haliotis midae, which is a long-lived species with a large corrugated shell that provides a habitat for diverse benthic organisms. ... -
Conservation and ecotourism on privatised land in the Mara, Kenya: The case of conservancy land leases
(Institute for Poverty, Land and Agrarian Studies, University of the Western Cape, 2012)This paper investigates private sector investment in conservation and ecotourism through conservancy land leases in the Mara region of Kenya. In a recent and growing tourism development, groups of Maasai landowners are ... -
Conservation status and threats for African reptiles
(Elsevier, 2016)The assimilation of information on taxonomy, distribution, basic ecology and conservation status of Africa's reptiles lags far behind that for most other continents. Many regions of mainland Africa are rarely surveyed, ... -
Cross-shelf movement of chrysaora fulgida (scyphozoa; discomedusae) off namibia inferred from stable isotopes (δ15n and δ13c)
(Taylor and Francis Group, 2021)Large and small specimens of two species of metagenic Scyphozoa (true jellyfishes) can be found in nearshore waters off central Namibia throughout the year. Whereas populations of Chrysaora ... -
Decorum in nature: Impala (Aepyceros melampus melampus) dung middens follow spatial point patterns in Mukuvisi Woodland, Zimbabwe
(Taylor and Francis Group, 2023)Guided by the Optimum Foraging Theory,the Avoidance Concept, and assuming that the impala Aepyceros melampus melampus defecate purposevely at dung middens, we hypothe-sized that the impala’s dung midden locations do not: ... -
Deep-sea fisheries as resilient bioeconomic systems for food and nutrition security and sustainable development

(Wiley, 2023)High pathogenicity avian infuenza (HPAI) clade 2.3.4.4b H5N8 virus was detected in coastal seabirds in late 2017 in South Africa, following a devastating epidemic in the commercial poultry and ostrich industries. By May ... -
Development of a compendium of local, wild-harvested species used in the informal economy trade, Cape Town, South Africa
(Resilience Alliance, 2012)Wild harvesting has taken place over millennia in Africa. However urbanization and cash economies have effectively altered harvesting from being cultural, traditional, and subsistence activities that are part of a rural ... -
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
(Wiley, 2022)Latitudinal range limits for mangroves on high-energy, wave-dominated coasts are controlled by geomorphological features and estuarine dynamics. Mangroves reach a southern global range limit along the South African ... -
Does phylogeny have an influence on the date of first description? A comparative study of the world's fishes
(Elsevier, 2020)The process of species description is not random, and understanding the factors that in- fluence when a species is first described (the date of first description, DoFD) allows us to target environments and/or species' ... -
The effect of anthropogenic noise and weather conditions on male calls in the bladder grasshopper Bullacris unicolor
