Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: RJ Karssing --- , South Africa NA Rivers-Moore --- , South Africa K Slater --- Department of Environmental Sciences, South AfricaCurrent literature suggests that little, if any, research has been conducted in South Africa to determine the impact of alien trout on indigenous amphibian biodiversity. The aim of this study was to establish whether waterfalls in the uKhahlamba Drakensberg Park,... -

Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Heidi J. Rockney --- , , USA Caleb Ofori-Boateng --- , Ghana Natsuko Porcino --- , , USA Adam D. Leaché --- , , USADNA barcoding has been proposed as a means of quick species identification using a short standardised segment of DNA. The established barcode gene for animals—the mitochondrial gene cytochrome oxidase one (CO1)—has been plagued by primer failure and low species identification... -

Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: JohnC. Poynton --- Natural History Museum, UKLaurent (1954) transferred a large number of species then in Arthroleptis to the genus Schoutedenella, which up to that time was a monotypic genus distinguished by de Witte (1921) from Arthroleptis on the grounds of lacking maxillary teeth. Laurent's concept... -
