Extraordinary Lecturer
Dr. Kerry Hadfield Malherbe
Kerry Malherbe began her post-doctoral fellowship in September 2012 studying the parasitic isopods from the family Cymothoidae. This project aims at completely revising the cymothoid isopods from around the world. These isopods can cause skin damage, lesions, anaemia and may even lead to the death of the host in extreme cases. Thus, an in-depth study on the biodiversity of these parasites is necessary to compile data on their taxonomic placements, occurrence, distribution, and hosts to determine effects these parasites are having on fish populations. This work is a continuation of her PhD work where she reviewed three cymothoid genera (Ceratothoa Dana, 1852, Cinusa Schioedte&Meinert, 1884, and CymothoaFabricius, 1787) known from southern Africa. The current project continues with this taxonomic and systematic revision, including descriptions of new species from South Africa and abroad. Furthermore, the molecular typing of these genera from South Africa will also be done for accurate identification and more insight into the phylogenetic relationships of these isopods. This genetic work on the South African species would also be the first for these isopods in the country and could provide valuable information for future research.
Extraordinary Lecturer
Dr. Courtney Cook
Courtney began her postdoctoral research at the NWU in September 2012, after completing her Ph.D. at the University of Johannesburg in the field of tortoise apicomplexan parasite biodiversity and multi-element metal fingerprinting with the utilisation thereof in the conservation of South African tortoises. The postdoctoral research in which she is currently involved entails the apicomplexan biodiversity of different research fields involving members of the fishes from around the world, reptiles, amphibians and birds from South Africa, with the aim of the taxonomic and phylogenetic positioning these animals’ parasites. Phylogenetics is a field of biology concerning the identification and elucidation of evolutionary relationships, or evolutionary history, such as among genera and species. Parasites such as apicomplexan parasites display very few morphological or life-cycle traits that differentiate them on a morphological scale. However, on a genetic scale, differentiation is possible by the use of conservative and non-conservative gene fragments, such as that of the 18S rDNA and Cytochrome b mtDNA genes respectively. Current research projects include an international collaboration with the department of Biological Sciences of Arkansas State University, USA, researching the apicomplexan biodiversity of fishes of the eastern Caribbean, US and British Virgin Islands, and a collaboration with Kingston University, UK, researching population genetics of apicomplexan parasites parasitemic to South African herpatofauna; also a national collaboration with the University of the Free State, researching the taxonomy and phylogeny of neglected and new apicomplexans of reptiles and birds, and an intradepartmental collaboration with the African Amphibian Conservation Research Group, describing novel species of herpatofaunal apicomplexans respectively with the use of both morphological and molecular tools. Such research has led to a number of publications of international standards, with further output anticipated.

Postdoctoral fellow
Dr. Rachel Welicky
Rachel Welicky is a postdoctoral fellow from Arkansas State University. Her research interests are in understanding the interactions between coral reef fish and the parasites that infect them. During her PhD research, she examined the effects of Anilocra infection on the behavior and physiology of Caribbean reef fish. Like many other scientists, her dissertation research only left her with more questions, and the questions that most interest her require a better understanding of the biology of Anilocra. There is very little actually known about Anilocra, and that’s where the WRG and her current research comes into play! As part of the WRG, she is learning as much as she can about Anilocra using both taxonomic and molecular approaches. By gaining a better understanding about how Anilocra species vary with respect to morphology and genetics, she will be able to conduct more informed ecological studies about Anilocra-host interactions.
