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 ... -
Felicia douglasii (Asteraceae-Astereae), a distinctive new species from the Cape Floristic Region, South Africa
(Elsevier, 2017)Felicia Cass. (Asteraceae) is the largest of the African members of tribe Astereae, and comprises ±90 species from southern and tropical Africa to Arabia. As currently circumscribed, it is rather weakly diagnosed by the ... -
Heavy metals in the irrigation water, soils and vegetables in the Philippi horticultural area in the Western Cape Province of South Africa
(Springer Verlag, 2014)The aims of this study were to investigate the extent of heavy metal contamination in the Philippi horticultural area in the Western Cape Province, South Africa. Concentrations of Cd, Cr, Cu, Mn, Ni, Pb and Zn were ... -
Predominant atmospheric and oceanic patterns during coastal marine heatwaves
(Frontiers Media, 2017)As the mean temperatures of the worlds oceans increase, it is predicted that marine heatwaves (MHWs) will occur more frequently and with increased severity. However, it has been shown that variables other than increases ... -
Body of evidence: forensic use of baseline health assessments to convict wildlife poachers
(CSIRO Publishing, 2013)CONTEXT. Given the immense impact of wildlife trade, disease and repatriations on populations, health assessments can" "provide powerful forensic material to help convict wildlife poachers and minimise risks of releasing ... -
Self-maintaining or continuously refreshed? The genetic structure of Euphausia lucens populations in the Benguela upwelling ecosystem
(Oxford University Press, 2013)Populations of Euphausia lucens over the shelf of the southern Benguela upwelling region could be self-maintaining. Alternatively, they could be continually refreshed by expatriates from the SW Atlantic that enter the ... -
A global infrageneric classification system for the genus Crotalaria (Leguminosae) based on molecular and morphological evidence
(Botanischer Garten und Botanisches Museum, 2013)Crotalaria is a large genus of 702 species with its centre of diversity in tropical Africa and Madagascar and secondary radiations in other parts of the world. The current infrageneric classification system is based on ... -
Beyond the jellyfish joyride and global oscillations: advancing jellyfish research
(Oxford University Press, 2013)There has been debate in the literature recently about increases in jellyfish populations in response to anthropogenic change, and this has attracted widespread media interest. Despite an international collaborative ... -
A taxonomic revision of the Pteronia camphorate group (Astereae, Asteraceae)
(Elsevier, 2017)As a first step towards a comprehensive revision of Pteronia (Asteraceae, Astereae), we present here a taxonomic treatment of the Pteronia camphorata group, in which we recognise three species. The group includes the type ... -
