Summer and winter differences in zooplankton biomass, distribution and size composition in the KwaZulu-Natal Bight, South Africa
(National Inquiry Services Centre (NISC), 2016)Zooplankton biomass and distribution in the KwaZulu-Natal Bight were investigated in relation to environmental parameters during summer (January–February 2010) and winter (July–August 2010). Mean zooplankton biomass was ... -
Sublittoral seaweed communities on natural and artificial substrata in a high-latitude coral community in South Africa
(National Inquiry Services Centre (NISC), 2016)Coral mortality may result in macroalgal proliferation or a phase shift into an alga dominated state. Subtidal, high-latitude western Indian Ocean coral communities at Sodwana Bay on the KwaZulu-Natal coast, South Africa, ... -
Testing for the occurrence of pilchard herpesvirus (PHV) in South African sardine Sardinops sagax
(National Inquiry Services Centre (NISC), 2016)Catches of South African sardine Sardinops sagax have declined in recent years from about 200 000 t harvested annually during the period 2002–2006 to less than 100 000 t. Consequently, some companies are now importing ... -
Riverine dominance of a nearshore marine demersal food web: evidence from stable isotope and C/N ratio analysis
(National Inquiry Services Centre (NISC), 2016)The Thukela Bank, KwaZulu-Natal, supports a diverse ecosystem and South Africa’s only prawn fishery. Oceanographic studies suggest riverine input is not important for the biology of this system, whereas biological studies ... -
Plastic ingestion by estuarine mullet Mugil cephalus (Mugilidae) in an urban harbour, KwaZulu-Natal, South Africa
(National Inquiry Services Centre (NISC), 2016)Coastal urban environments have high plastic pollution levels, and hence interactions between plastic debris and marine life are frequent. We report on plastic ingestion by mullet Mugil cephalus in Durban Harbour, ... -
Essential metal and metalloid elements in the Philippi Horticultural area, and their uptake into selected vegetable crops
(Taylor & Francis, 2018)This study evaluated Co, Cr, Mn, Ni, Se, Sn and V status in the soils of the PHA, as well as the vegetables produced on these soils. We also determined the agronomic sources of these elements to the soils in the PHA. ... -
Siphonophores from surface waters of the Colombian Pacific Ocean
(Cambridge University Press, 2018)Siphonophores are colonial hydrozoans that feed on zooplankton including fish larvae, and occur throughout the world’s oceans from surface waters to ocean depths. Here we describe the composition of hyponeustonic siphonophores ... -
Legume phylogeny and classification in the 21st century: Progress, prospects and lessons for other species-rich clades
(Botanischer Garten und Botanisches Museum, 2013)The Leguminosae, the third-largest angiosperm family, has a global distribution and high ecological and economic importance. We examine how the legume systematic research community might join forces to produce a comprehensive ... -
Phylogenetic position and revised classification of Acacia s.l. (Fabaceae: Mimosoideae) in Africa, including new combinations in Vachellia and Senegalia
(Oxford University Press, 2013)Previous phylogenetic studies have indicated that Acacia Miller s.l. is polyphyletic and in need of reclassification. A proposal to conserve the name Acacia for the larger Australian contingent of the genus (formerly ... -
Female preference for blue in Japan blue guppies (Poecilia reticulata)
(Springer Verlag, 2013)Guppies (Poecilia reticulata) are widely used as a model species in mate choice studies. Although native to South America, guppies have been introduced to natural water bodies in disparate regions of the globe. Here, for ... -
Population ecology of Psammobates oculifer in a semi-arid environment
(Taylor & Francis and UNISA Press, 2013)We studied the ecology of Psammobates oculifer over 13 months near Kimberley, South Africa, to ascertain if the population’s life history traits conform to chelonian patterns in arid environments. Capture rates were highest ... -
Lasiosiphon rigidus, a new species from the Tankwa Karoo and two new combinations in the genus for South Africa
(MDPI, 2013)Thymelaeaceae are well represented in southern Africa, with ± 190 species in nine genera (Bredenkamp & Beyers 2000; Beaumont et al. 2009). Preliminary phylogenetic analyses of nuclear and plastid DNA sequences (Van der ... -
Molecular and morphological analysis of subfamily Alooideae (Asphodelaceae) and the inclusion of Chortolirion in Aloe
(Botanischer Garten und Botanisches Museum, 2013)Asphodelaceae subfam. Alooideae (Asparagales) currently comprises five genera, four of which are endemic to southern Africa. Despite their importance in commercial horticulture the evolutionary relationships among the ... -
Possible aquaculture development in Nigeria: evidence for commercial prospects
(David Publishing, 2017)The cultivation of desirable aquatic organisms is becoming increasingly important as one of the fastest-growing agro-industrial activities in the world. Nigeria, over the years, practised traditional methods of aquaculture ... -
Seaweeds in two oceans: beta-diversity
(Frontiers Media, 2017)Several species assembly mechanisms have been proposed to structure ecological communities. We assess the biogeography of seaweeds along 2,900 km of South Africa’s coastline in relation to a thermal gradient produced by ... -
Hitting the right target: taxonomic challenges for, and of, plant invasions
(Oxford University Press, 2013)This paper explores how a lack of taxonomic expertise, and by implication a dearth of taxonomic products such as identification tools, has hindered progress in understanding andmanaging biological invasions. It also ... -
Towards a new classification system for legumes: Progress report from the 6th International Legume Conference
(Elsevier, 2013)Legume systematists have been making great progress in understanding evolutionary relationships within the Leguminosae (Fabaceae), the third largest family of flowering plants. As the phylogenetic picture has become clearer, ... -
Two new species of Trachyandra sect. Liriothamnus (Xanthorrhoeaceae, Asphodeloideae) from the Western and Eastern Cape Provinces of South Africa
(2013)Trachyandra eriocarpa and T. bulbosa are two new species from Northern and Eastern Cape Provinces of South Africa. They are placed in T. sect. Liriothamnus based on their wiry roots, the cataphylls not forming membranous ... -
Jellyfication of marine ecosystems as a likely consequence of overfishing small pelagic fishes: Lessons from the Benguela
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 2013)Changes in two contrasting ecosystems of the Benguela upwelling region, one dominated at mid-trophic level by jellyfishes (Namibia, northern Benguela ecosystem, where small pelagic fish abundance has been severely depleted) ... -
Variation in the daily activity, movement and refugia of Critically Endangered geometric tortoises, Psammobates geometricus, in autumn and spring
(Taylor & Francis, 2017)To help assess habitat requirements of Critically Endangered geometric tortoises, we used thread-trailing to measure daily activity, movements and refugia of adult Psammobates geometricus in autumn and spring 2002. We found ...
