Overview

Welcome to University of Venda’s Department of Zoology

We are situated in a truly fascinating region of the world, the Vhembe District, South Africa and we are the only Zoology Department in the world situated within a UNESCO Biosphere Reserve!

Our department consists of dedicated staff members involved with teaching and training zoologists, ecologists and nature conservationists. As a department, we exist to conduct research and make a difference to the lives of our students within the context of a developing rural region.

Recent exciting developments

The Department of Zoology recently published its first ever paper in the prestigious international journal Science. This was also the very first time the University of Venda has featured in this journal. Professor Yoshan Moodley headed the genetic analysis of the Helicobacter pylori strain in the stomach of the Tyrolean Iceman “Ötzi”, who has been dead for over 5000 years, but perfectly mummified in an Alpine glacier. He discovered that the Iceman’s strain belonged to a bacterial population that is different to that which can be found in modern-day European stomachs, implying that major human migrations into Europe must have occurred within the last 5000 years. News of the article was featured in the New Y ork Times, the Wall Street Journal, The Guardian and many other international newspapers. Read more about this fantastic finding on the Science website: http://science.sciencemag.org/content/351/6269/162.full The Department will be offering our new Diploma in Freshwater Technology from 2014, equip students for a career in freshwater biology and freshwater resource management, by training them as technical staff with a practical working knowledge of aspects such as assessment. Potential career opportunities exist in the Department of Water Affairs, national and provincial departments of Environmental Affairs, Water Boards (Rand Water Board, Umgeni Water Board and Sedibeng Water), municipalities and local authorities as well as Catchment Management Agencies (CMAs) and Water User Associations (WUAs). The University of Venda has been awarded a SARChi Chair entitled ”Biodiversity and Change in the Vhembe Biosphere Reserve”. This initiative

Research

Current research and collaborations

Besides our teaching and administrative duties, we are also involved with research on global change ecology, invasive aliens, freshwater conservation, molecular genetics and taxonomy.

Dr Paul Fouche is currently working on a project on Nandonni Dam registered with the Water Research Commission, with collaborators from University of Limpopo. Other project include among others a long term monitoring of fish populations in Kruger National park with Prof. Nico Smit from University of Johannesburg. He is also part of the provincial biomonitoring team at national meetings of the River Health Programme.

Prof Ben van der Waal is involved with a project on water resource management in the Caprivi Strip funded by WWF. He has just returned!

Dr Tshifhiwa Nanngambi has recently registered a project on genetic divergence among different Venda groups with Univen’s Research and Publications Committee. She is also collaborating with Dr from Natal Museum on Mollusca or something like that. She has also built up a new genetics laboratory at our department.

Prof. Jan Crafford is involved with supervising Mr Koos Steyn from UNIVEN School of Environmental Sciences on the use of trap crops in Macadamia orchards as a viable pest control strategy. He is supervising Mr project testing island biogeography theory in natural forest fragments in a grassland matrix, otherwise known colloquially as leopard bush.

Dr Stefan Foord, a core team member of the DST-NRF Center for Excellence in Invasion Biology, has a project registered with the NRF on spider diversity in the Savanna biome, and also conducts extensive sampling for the SANSA project headed by Prof Ansie Dippenaar Schoeman from the Agricultural Research Council. He is also supervising Dr Norbert Hahn’s Post-Doctoral project on the impact of invasive aliens in the Soutpansberg and and Caswell Munyai’s project on ants along an elevational transect in the Soutpansberg. He is also co-supervising honours students for 2010.

ASSOC PROF STEFAN FOORD
Head of department

Much of my research has focused on invertebrate composition in space and time, both in natural and (Foord et al. 2008, Muelelwa et al. 2010) and human-dominated ecosystems (Foord et al. 2003). Working on invertebrates has lead to both taxonomic work (Foord 2008), optimal sampling protocols (Muelelwa et al. 2010) and a search for surrogates of their diversity (Foord et al. 2013). But the broader relevance of this work falls within the context of global change drivers such as the effects of land use change, habitat fragmentation, alien invasive organisms and possible impacts of climate change on biodiversity. This work provides insights into the scale at which landscapes should be managed for conservation (Schoeman & Foord 2012), baseline information (Foord et al. 2011, Dippenaar-Schoeman et al. 2012) and a framework for monitoring the response of assemblages over time (Foord et al. 2003) but also identifies the drivers and processes that underlie this diversity (Munyai & Foord 2012). Recent research has shifted some and some of  my postgraduate students focus on functional perspectives in community assembly and the functional importance of diversity in agro-ecosystems particularly within the context of ecological networks, see student projects. I am currently head of the Department of Zoology, a Core Team Member of the Centre for Excellence for Invasion Biology and have ongoing collaborations with the Agricultural Research Council and the University of Bloemfontein. I teach Ecology and Conservation Biology at undergraduate and postgraduate levels.

PROF YOSHAN MOODLEY
Genetics

After over a decade abroad, I have returned to Africa. I am now based at the University of Venda – the only South African University located in the tropics, and within a biosphere reserve that includes the world famous Kruger National Park. While remote (a five hour drive from Johannesburg), the Vhembe region offers accessibility to sophisticated research facilities at the university, while affording researchers the opportunity to live in a forgotten, scenic and highly diverse corner of Africa. I have always been intrigued by systematic (top-down) and population genetic (bottom-up) approaches to the study of evolution, and my experience has shown me that both approaches are fully complementary, and indeed essential for the elucidation of evolutionary mechanisms. Evolutionary history, therefore, is a central theme throughout my research. I have worked with several taxa from bacteria to large mammals (see publication list). Below is a brief description of just some of the exciting research project currently being carried out.

Tracing human migrations

My group continues the very successful research on the phylogenetic and demographic history of the human pathogen (Helicobacter pylori) could be used as a marker for prehistoric human migrations, and can be more reliable than human DNA itself. This is because high bacterial mutation and recombination rates allow faster lineage sorting among continents, with greater diversification within continents. This has allowed us to trace prehistoric human migrations In collaboration with Dr. Silvia Ghirotto (University of Ferrara, Italy) we are currently fitting coalescent models to a massive MLST data set of strains from Siberia and Central Asia. We hope to determine the number of independent migration events that led to the peopling of the Americas. My group is also working in collaboration with Dr. Yoshio Yamaoka of the Baylor College of Medicine (Houston, USA). In this project we are focussed on the island of Japan and will study the H. pylori diversity there using whole genome sequences.

Speciation

The process by which new species are formed has intrigued biologists long before Darwin introduced us all to natural selection. Speciation is at its most rampant during an adaptive radiation, where lineages rapidly evolved from a single common ancestor. What drives this process? What evolutionary forces are most dominant? One group of bovids that are particularly well suited to identify potential answers to these questions is the Tragelaphine antelopes. That is because they contain both high levels of diversity – just compare an eland with a bushbuck for size – but they are also well known for their high levels of convergent evolution – compare the evolutionary unrelated yet phenotypically similar kudu/lesser kudu or nyala/mountain nyala. What speciation processes have led to this high convergence? Together with Prof. Michael Hofreiter (University of Potsdam, Germany), we have already sequenced the whole genomes of a representative of each Tragelaphus species and we are presently being assembled. We will scan these genomes for signatures of selection, determine the genomic regions affected and correlate these with genes known to be associated with phenotypic traits.

Conservation Genetics

African rhinoceros are among the most endangered mammals in the world, yet their evolutionary histories are largely unknown. This is ironic, given that a firm understanding of population structure is essential for efficient conservation management. We are currently publishing the results of a pan-African study funded by the International Rhino Foundation (IRF) that reconstructs the phylogenetic history of both species. Together with Prof. Michael Bruford and Dr. Isa-Rita Russo (Cardiff University, UK), we recently obtained another research grant from the IRF to establish the first black rhinoceros whole genome assembly, and compare this to resequenced genomes from other southern African populations.

Phylogeography

I am always very keen on the interaction between genes and their spatial, climatic and ecological environments. Together with Prof Petra Quillfeldt, Dr. Juan Masello (University of Giessen, Germany) and other colleagues, we have embarked on an ambitious project in which we will elucidate the comparative phylogeography of petrel (Pachyptila) species in sub-Antarctic waters. These highly specialised seabirds, capable of migrating thousands of kilometres between breeding and feeding grounds, are another product of a Pleistocene adaptive radiation. We aim therefore to determine the evolutionary relationships and levels of gene flow among them, and then ascertain the underlying evolutionary mechanisms responsible.

Research opportunities

I am in the process of establishing a high end molecular zoology lab, capable of generating DNA libraries for next generation sequencing applications such as RADseq, RNAseq and whole genome sequencing. The lab will also include an ancient DNA facility for museum and other “difficult” specimens. Concurrently, I am setting up a bioinformatics hub at the University that will process the NGS data that we generate. We are presently looking for capable lab members at all academic levels. So if you are seriously interested in one of the themes outlined above, and would like to work and live within an African biosphere reserve, then do get in contact with me.

Undergraduate teaching

I teach a comprehensive course in evolutionary genetics at the third year level. Our three year undergraduate program has been restructured with the aim of producing graduates skilled in evolutionary thinking and genetic analyses.

Honours

My honours course focuses on further building on theoretical and analytical skills. It also serves to introduce students to postgraduate research in conservation genetics and molecular ecology.

ASSOC PROF IRENE BARNHOORN
Fresh Water Toxicology

Irene’s research interest is in freshwater aquatic sciences with the emphasis on environmental endocrine disruption (ecotoxicology) and the safe consumption of wild fish. Key findings of her work include incidences of intersex in a South African freshwater fish species, Clarias gariepinus, in the Rietvlei Dam (Barnhoorn et al., 2004) and in a freshwater fish species, Oreochromis mossambicus, from an area where DDT (known EDC) spraying is on-going (Barnhoorn et al., 2010). Intersex in fish is the presence of both male and female reproductive features within the same individual. This is of concern as it may cause changes in the reductive health of fish species and is usually associated with exposure to EDCs. Reports from the UK and Europe indicated exposure to EDCs since 1994 and my findings show that  South African waters are not excluded from endocrine chemical pollution. The findings also have significance value for humans: Not only does EDCs exposure leads to intersex in fish species, but global reports  show a number of reproductive, developmental, behavioural and immunological abnormalities  in both humans and other wildlife species. This may have an impact on populations surrounding and using these polluted water sources. This research formed the baseline for future studies on the possible effects of EDCs on freshwater fish and aquatic ecosystems in South Africa. Completed research projects formed a basis in which protocols were developed to apply in EDCs research. I will focus on environmental endocrine disrupters and the safe human consumption of wild fish species. The concept will in future make an important contribution in South Africa to provide safe food for the local people/ everybody. Irene teaches third year Eco-physiology and Limnology.
