Biodiversity: so much more than legs and leaves
(AOSIS OpenJournals, 2013)Microorganisms inhabit virtually every possible niche on Earth, including those at the outer envelope of survival. However, the focus of most conservation authorities and ecologists is the ‘legs and leaves’ side of biology ... -
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 ... -
Body of evidence: forensic use of baseline health assessments to convict wildlife poachers
(CSIRO Publishing, 2013)CONTEXT. Given the immense impact of wildlife trade, disease and repatriations on populations, health assessments can" "provide powerful forensic material to help convict wildlife poachers and minimise risks of releasing ... -
Carybdea branchi, sp. nov., a new box jellyfish (Cnidaria: Cubozoa) from South Africa.
(Magnolia Press, 2009)A common and conspicuous member of the medusan fauna of South Africa has been the subject of repeated taxonomic confusion. After having been mistakenly identified by earlier workers as either Carybdea alata or Tamoya ... -
A catalogue with keys to the non-geniculate coralline algae (Corallinales, Rhodophyta) of South Africa
(Elsevier, 2008)Non-geniculate coralline red algae are common in all of the world’s oceans, where they often occupy close to 100% of the primary rocky substratum. The South African rocky subtidal and intertidal habitats in particular, ... -
Changes in mangroves at their southernmost African distribution limit
(Elsevier, 2020)Mangroves in South Africa occur at one of the most southerly locations in the world, which provides a unique opportunity to study their dynamic responses to anthropogenic and natural perturbations. The exposed high-energy ... -
Chromista
(Wiley Online, 2011)The concept of chromists, at its most expansive, includes the heterokonts (stramenopiles), alveolates, rhizarians, heliozoans, telonemians, haptophytes and cryptophytes. There is mounting evidence that this grouping is not ... -
The chromista
(Wiley Online, 2003)As a group, the chromists show a diverse range of forms from tiny unicellular, flagellates to the large brown algae known as kelp. Molecular studies have confirmed the inclusion of certain organisms once considered Fungi, ... -
Clathromorphum tubiforme sp. nov. (Rhodophyta, Corallinaceae) in South Africa with Comments on Generic Characters
(Walter de Gruyter, 1995)A nongeniculate, crustose coralline alga (Rhodophyta, Corallinaceae) from South Africa, is found growing epiphytically on fronds of species of the geniculate genus Ampiroa. Analysis of the vegetative and reproductive ... -
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 ... -
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 ... -
Community and marine conservation in South Africa: Are we still missing the mark?
(Frontiers Media, 2022)Marine Protected Areas (MPAs) in South Africa have a long history with currently 5% of the mainland’s ocean territory protected. The MPAs are celebrated and appreciated for their representative coverage of several habitat ... -
Comparative phylogeography of parasitic Laelaps mites contribute new insights into the specialist-generalist variation hypothesis (SGVH)
(BMC, 2018)BACKGROUND: The specialist-generalist variation hypothesis (SGVH) in parasites suggests that, due to patchiness in habitat (host availability), specialist species will show more subdivided population structure when compared ... -
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. ... -
A comparison of various seaweed-based diets and formulated feed on growth rate of abalone in a land-based aquaculture system
(Springer, 2007)The effects of different diets on growth in the cultured South African abalone, Haliotis midae (Linnaeus), was investigated. Growth of juvenile Haliotis midae was monitored on a commercial abalone farm over a period of ... -
A complete guide to the snakes of Southern Africa
(African Journal of Herpetology, 2023)Background: The new edition of A Complete Guide to the Snakes of Southern Africa represents the third iteration in a series of books that started three decades ago. The latest edition replaces the 2004 edition (Marais ... -
The conservation status and population decline of the African penguin deconstructed in space and time
(Wiley-Blackwell, 2020)Understanding changes in abundance is crucial for conservation, but population growth rates often vary over space and time. We use 40 years of count data (1979–2019) and Bayesian state-space models to assess the African ... -
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, ...
