Observations on euphausiid communities of the south coast of South Africa
(NISC (Pty) Ltd and Taylor& Francis, 1995)A total of 24 species of euphausiid was collected during a survey along the South African south coast during January 1992. Communities over the Agulhas Bank were of low diversity and abundance and were dominated by Nycliphanes ... -
Observations on the ecology of Pleurobrachia pileus (Ctenophora) in the southern Benguela ecosystem
(NISC (Pty) Ltd and Taylor & Francis, 2003)The vertical distribution, abundance and size composition of a population of Pleurobrachia pileus was studied during a six-day drogue study conducted off the west coast of South Africa in February 1995. The population was ... -
Observations on the pelagic decapod Pasiphaea semispinosa in the Benguela upwelling ecosystem
(NISC and Taylor & Francis, 1994)Information on vertical and horizontal distribution patterns, abundance and morphology of the decapod Pasiphaea semispinosa in the Benguela upwelling system is presented. P. semispinosa is the dominant pelagic decapod in ... -
Of dead man's fingers, cord weed and hanging wrack: common brown seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2000)In this, the second in the series on common intertidal seaweeds of the Cape Peninsula, we look at the brown seaweeds common to our rocky shores, with the exception of kelp, which will be covered in the next issue of Veld ... -
Of dinner plate, cochlear and pacman corallines: seven common intertidal encrusting red seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2001)In the fifth and final part of this series of articles on common intertidal seaweeds of the Cape Peninsula, we look at encrusting coralline algae. These encrusting coralline and red seaweeds are widespread in shallow waters ... -
Of purple laver, tongue weed and hedgehog seaweed: common red seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2001)The fourth part of our series on the common intertidal seaweeds of the Cape Peninsula looks at the red seaweeds, which form by far the largest group of seaweeds on the Peninsula and dominate the mid to lower intertidal ... -
Of sea bamboo, split fan kelp and bladder kelp: three common kelp species of the Cape Peninsula and West Coast
(Botanical Society of South Africa, 2001)The third part in our series on the common intertidal seaweeds of the Cape Peninsula looks at the kelps, the giant brown seaweeds that occur in the subtidal and intertidal gullies of the Cape Peninsula and the west coast. ... -
Of sea lettuces and green sea intestines: common intertidal green seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2000)Most of us know seaweed as that slippery stuff growing on the rocks or lying strewn along the beach at low tide making the beach smell. But do we really know much about them? Although not entirely true, seaweeds (or marine ... -
Phylogenetic placement and generic re-circumscriptions of the multilocular genera Arenifera, Octopoma and Schlechteranthus (Aizoaceae: Ruschieae): Evidence from anatomical, morphological and plastid DNA data
(International Association for Plant Taxonomy (IAPT), 2016)"Ruschieae is the largest tribe in the highly speciose subfamily Ruschioideae (Aizoaceae). A generic-level phylogeny for the tribe was recently produced, providing new insights into relationships between the taxa. Octopoma ... -
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 ... -
A revision of the genus Strongylodesma Lévi (Porifera: Demospongiae: Latrunculiidae) with descriptions of four new species
(Cambridge University Press, 2009)The sponge genus Strongylodesma is reviewed and redefined, and now accommodates eight closely related species. The type species of Strongylodesma Le´vi is redescribed and an additional two new species are described from ... -
The role of encrusting coralline algae in the diets of selected intertidal herbivores
(Springer Verlag, 2006)Kalk Bay, South Africa, has a typical south coast zonation pattern with a band of seaweed dominating the mid-eulittoral and sandwiched between two molluscan-herbivore dominated upper and lower eulittoral zones. Encrusting ... -
Salinity of irrigation water in the Philippi farming area of the Cape Flats, Cape Town, South Africa
(Water Research Commission, 2013)This paper explores the nature, source and spatial variation of the salinity of water used for irrigation in a coastal urban farming area in Cape Town, South Africa, where water from the Cape Flats aquifer is drawn into ... -
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 ... -
Seaweed diversity associated with a Brazilian tropical rhodolith bed
(Universidad Autónoma de Baja California, 2010)This study describes the predominantly tropical, subtidal seaweed populations growing on rhodoliths between 4 and 18 m depth in the southern part of Espírito Santo State (Brazil). Qualitative and quantitative sampling ... -
