Assessing the likelihood of gene flow from sugarcane (Saccharum Hybrids) to wild relatives in South Africa
(Frontiers Media, 2018)Pre-commercialization studies on environmental biosafety of genetically modified (GM) crops are necessary to evaluate the potential for sexual hybridization with related plant species that occur in the release area. The ... -

Diversity and biogeography of frogs in the genus Amnirana (Anura: Ranidae) across sub-Saharan Africa
(Elsevier, 2018)Frogs in the genus Amnirana (family Ranidae) are widely distributed across sub-Saharan Africa and present a model system for exploring the relationship between diversification and geography across the continent. Using ... -
First record of Phasmarhabditis papillosa (Nematoda: Rhabditidae) in South Africa, and its virulence against the invasive slug, Deroceras panormitanum
(Brill, 2017)Worldwide interest in Phasmarhabditis originates from the successful commercialisation of P. hermaphrodita as a biological control agent against molluscs in Europe. To date, P. hermaphrodita has not been isolated from South ...
