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 ... -
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, ... -
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 ... -
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 ... -
Conservation status of large branchiopods in the Western Cape, South Africa
(Springer Verlag, 2007)Temporary wetlands are an ecologically and economically important habitat in South Africa. They harbor large branchiopods, known to be flagship species of nonpermanent aquatic habitats, and sensitive to land use changes. ... -
A cursory look at the fishmeal/oil industry from an ecosystem perspective
(Frontiers Media, 2021)By supporting the fishmeal industry, are we competing with marine predators? Should we be taking away food from marine predators to subsidize agriculture? If not for human consumption, should forage fish be left in the ... -
Descriptive epidemiology of and response to the high pathogenicity avian influenza (h5n8) epidemic in South African coastal seabirds, 2018
(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 ... -
The diurnal activity budgets of extralimital giraffe (Giraffa camelopardalis giraffa) in the Western Cape Province, South Africa
(Wiley, 2023)Despite being an extralimital species in the region, South African giraffes (Giraffa camelopardalis giraffa, Schreber 1784) are continuously being introduced into the Albany Thicket Biome of the Western Cape Province of ... -
Ecological significance of deep-layer sloughing in the eulittoral zone coralline alga, Spongites yendoi (Foslie) Chamberlain (Corallinaceae, Rhodophyta) in South Africa.
(Elsevier, 1994)The crustose coralline alga Spongites yendoi (Foslie) Chamberlain (Corallinaceae, Rhodophyta) dominates the lower eulittoral zone along the South Coast of South Africa, together with the limpet Patella cochlear Born. This ... -
Effects of herbivore grazing on the physiognomy of the coralline alga Spongites yendoi and on associated competitive interactions
(National Inquiry Services Centre (NISC) and Taylor & Francis, 2008)The territorial gardening limpet Scutellastra cochlear occurs along the south and southern west coasts of South Africa, while one of its primary food items, the encrusting coralline alga Spongites yendoi, extends much ... -
The effects of long-term exclusion of the limpet Cymbula oculus (Born) on the distribution of intertidal organisms on a rocky shore
(NISC (Pty) Ltd and Taylor & Francis, 2009)Zonation patterns on rocky shores are typically as a result of both physical factors and biological interactions. Physical factors generally set the upper limits of species distributions, while biological interactions ... -
Environmental response and ph tolerance of induced co2 in ulva rigida c.agardh, 1823(Chlorophyta) under controlled conditions
(PAS FORUM, 2022)The increase in integrated multitrophic aquaculture (IMTA), where seaweed (particularly Ulva rigidaC.Agardh, 1823) is used as a feedstock and a wastewater scrubber in South African IMTA systems, has necessitated research ... -
An estuary ecosystem classification that encompasses biogeography and a high diversity of types in support of protection and management
(Taylor & Francis, 2020)For nearly three decades, the Whitfield (1992) characterisation scheme served as a reference framework to type South African estuaries. We outline a revised ecosystem classification scheme that incorporates biogeographical ... -
First report of the melobesioid alga (Corallinales, Rhodophyta) Mesophyllum incisum (Foslie) Adey in South Africa
(Elsevier, 1997)Mesophyllum incisum is reported and studied for the first time in South Africa. It has a th all us surface (SEM) with Leptophyturn-type epithallial cells. TetraJbisporangial conceptacles are mound-like and lack a peripheral ... -
Forest canopy gaps offer a window into the future: The case of subtropical coastal forests within an urban matrix in South Africa
(INST NACIONAL INVESTIGACION TECHNOLOGIA AGRARIA ALIMENTARIA, 2021)Alien and indigenous species emergence patterns within canopy gaps in urban subtropical forests are poorly understood. This study compared canopy gap floristics in relation to abiotic and physical characteristics across ... -
Giants and titans: First records of the invasive acorn barnacles Megabalanus tintinnabulum (Linnaeus, 1758) and Megabalanus coccopoma (Darwin, 1854) on intertidal rocky shores of South Africa
(Regional Euro-Asian Biological Invasions Centre (REABIC), 2022)During intertidal rocky shore surveys on the east coast of South Africa in 2018, the non-indigenous giant purple barnacle Megabalanus tintinnabulum (Linnaeus, 1758), a well-known fouling and globally-invasive species, ... -
