Reconstructing the deep-branching relationships of the papilionoid legumes
(Elsevier, 2013)
Resolving the phylogenetic relationships of the deep nodes of papilionoid legumes (Papilionoideae) is essential to understanding the evolutionary history and diversification of this economically and ecologically important ...
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 ...
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 ...
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 ...
Implementing value chain analysis to investigate drivers and sustainability of Cape Town's informal economy of wild-harvested traditional medicine
(Routledge, 2015)
Despite a highly visible presence, policy-maker knowledge of the drivers and
participants in the informal economy of wild-harvested medicinal plants in Cape
Town remains limited. To illuminate the workings of this local ...
A TAXONOMIC REVISION OF THE OTHONNA BULBOSA GROUP (ASTERACEAE: SENECIONEAE: OTHONNINAE)
(Missouri Botanical Garden Press, 2019)
Othonna L. (Asteraceae: Senecioneae: Othonninae) is a genus of some 120 species concentrated in the Greater Cape Floristic
Region (GCFR) of South Africa, with a few species extending into southern Namibia, Angola, and ...
Predicting Shifts in the geographical distribution of two estuarine plant species from the subtropical and temperate regions of South Africa
(Springer, 2019-11-21)
Climate suitability maps are useful to determine changes in the distribution of species. The aim of this study was to predict the future distribution of two estuarine species (Bassia diffusa and Hibiscus tiliaceus) from ...
Happy Feet in a Hostile World? The Future of Penguins Depends on Proactive Management of Current and Expected Threats
(2019)
Penguins face a wide range of threats. Most observed population changes have
been negative and have happened over the last 60 years. Today, populations of 11
penguin species are decreasing. Here we present a review that ...
Epizootic ulcerative syndrome – first report of evidence from South Africa's largest and premier conservation area, the Kruger National Park
(ScienceDirect, 2019)
This study reports on the first evidence of genomic material of the causative agent for epizootic ulcerative syndrome (EUS), Aphanomyces invadans, from fish in the Limpopo River system and the Kruger National Park, South ...
