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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
Evolutionary history of the Corallinales (Corallinophycidae, Rhodophyta) inferred from nuclear, plastidial and mitochondrial genomes
(Elsevier, 2011)
Systematics of the red algal order Corallinales has a long and convoluted history. In the present study, molecular approaches were used to assess the phylogenetic relationships based on the analyses of two datasets: a large ...
Heydrichia cerasina sp. nov. (Sporolithales, Corallinophycidae, Rhodophyta) from the southernmost tip of Africa. Phycologia, 51(1): 11- 21
(International Phycological Society, 2012)
A new species of Heydrichia (Sporolithales), H. cerasina sp. nov., is described, found only on pebbles in the low intertidal zone along a 10 km stretch of the South African south coast from Cape Agulhas to Struisbaai. The ...
Rapid assessment of tissue nitrogen in cultivated Gracilaria gracilis (Rhodophyta) and Ulva lactuca (Chlorophyta)
(NISC, 2009)
Tissue nitrogen content and thallus colour were quantified using a rapid assessment method based on the Pantone® matt uncoated formula guide for raft-cultivated Gracilaria gracilis Steentoft Irvine et Farnham at Saldanha ...
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 ...
