Don't cut that 'grass'
(Botanical Society of South Africa, 2006)Introduction: Have you ever noticed the abundance of wildflowers on public open spaces during spring in Cape Town? I suppose some Capetonians would be aware of Rondebosch Common and the astonishing botanical diversity ... -
You use seaweeds for that?
(Botanical Society of South Africa, 2006)Introduction: The word seaweed is commonly used, yet to refer to these marine algae as 'weeds' is very far from the truth. Together with microscopic algae called phytoplankton and other photosynthetic organisms, seaweeds ... -
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 ... -
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. ... -
Structure of rhodolith beds from 4 to 55 meters deep along the southern coast of Espírito Santo State, Brazil
(Universidad Autónoma de Baja California, 2007)Rhodoliths are one of the most extensive benthic communities of the Brazilian continental shelf, but their structure is poorly known. The richest marine flora of Brazil’s coastal zone is found in Espírito Santo State and ... -
How to write a popular article
(SANCOR, 2008)This newsletter has criteria for the development of a popular article. -
Growth of market-size abalone (Haliotis midae) fed kelp (Ecklonia maxima) versus a low-protein commercial feed
(Taylor & Francis, 2008)The growth of grow-out abalone fed on kelp, with ca. 10 % dry weight protein content, was compared with that of those fed a new ,ca. 26 % protein, commercial feed in a flow-through system on a South African west coast ... -
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, ... -
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 ... -
Scale insects on ericas : an apparently natural, unnoticeable threat to local biodiversity
(Botanical Society of South Africa, 2008)Introduction: An excursion into the Limietberg Nature Reserve in the Bain's Kloof Mountains during the winter of 2006, one that I have undertaken regularly over the past ten years or so, had revealed a noticeably high ... -
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 ... -
The growth of post-weaning abalone (Haliotis midae Linnaeus) fed commercially available formulated feeds supplemented with fresh wild seaweed
(National Inquiry Services Centre (NISC) and Taylor & Francis, 2008)The effect of five formulated feeds, supplemented with fresh wild seaweed on the growth of post-weaning juvenile abalone (6 - 20 mm shell length), Haliotis midae Linnaeus was investigated by means of a growth trial at a ... -
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 ... -
Determining the most appropriate feeding regime for the South African abalone Haliotis midae Linnaeus grown on kelp
(Springer Verlag, 2008)Beach-cast kelp (the most widely used feed for commercially grown South African abalone) is plentiful during winter months when periodic storms cause kelp to wash ashore. During summer, however, this resource is not ... -
Groundwater discharges to aquatic ecosystems associated with the Table Mountain Group (TMG) aquifer: a conceptual model
(Water Research Commission, 2008)This paper reports on a conceptual model that was developed to describe the different groundwater discharge ‘types’ from the Table Mountain Group (TMG) aquifer, that contributes to the different components of the flow ... -
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 ... -
Taxonomy of rhodolith-forming species of Lithophyllum (Corallinales; Rhodophyta) from Espírito Santo State, Brazil
(International Phycological Society, 2009)The taxonomy of the rhodolith-forming species of Lithophyllum (Corallinales, Rhodophyta) found from Espirito Santo State, Brazil, were evaluated based on extensive subtidal sampling. A comparative analysis of the Brazilian ... -
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 ... -
