A catalogue with keys to the non-geniculate coralline algae (Corallinales, Rhodophyta) of South Africa
Maneveldt, Gavin; Keats, Derek; Chamberlain, Yvonne (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, ... -
The chromista
Maneveldt, Gavin; Keats, Derek (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
Chamberlain, Yvonne; Norris, R.E.; Keats, Derek; Maneveldt, Gavin (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.
Keats, Derek; Wilton, P.; Maneveldt, Gavin (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
Maneveldt, Gavin; Keats, Derek (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 ... -
Leptophytum foveatum Chamberlain & Keats (Rhodophyta, Corallinales) retaliates against overgrowth by other encrusting algae
Keats, Derek; Maneveldt, Gavin (Elsevier, 1994)The encrusting coralline alga, Leptophytum foveatum, is the most abundant crustose alga in the lower eulittoral zone at Yzerfontein and other exposed sites on the West Coast of South Africa. The surface of this species is ... -
Synarthrophyton papillatum sp. nov.: a new species of non-geniculate coralline algae (Rhodophyta, Corallinales, Hapalidiaceae) from South Africa and Namibia
Maneveldt, Gavin; Keats, Derek; Chamberlain, Yvonne (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 ... -
Three species of Mastophora (Rhodophyta: Corallinales, Corallinaceae) in the tropical Indo-Pacific Ocean: M. rosea (C. Agardh) Setchell, M. pacifica (Heydrich) Foslie, and M. multistrata sp. nov
Keats, Derek; Maneveldt, Gavin; Baba, Masasuke; Chamberlain, Yvonne; Lewis, Jane E. (International Phycological Society, 2009)Three species of Mastophora (Corallinaceae, Corallinales, Rhodophyta) were found in extensive studies of non-geniculate coralline algae in various areas of the tropical Indo-Pacific, including French Polynesia, Fiji, Ryukyu ... -
