The Department of Zoology, by virtue of its unique biogeographic position, is focused on bringing its research and teaching to bear on sustainable rural livelihoods. In essence, the aim is to resolve conflicts between rapidly developing rural communities and ecosystems so that ecosystem resilience and services are not irreparably compromised for future generations. This research is all firmly entrenched in a rural setting where teaching is focused on students from disadvantaged backgrounds. The department’s expertise is therefore focused on the conservation of natural animal biodiversity, assessment of ecosystem health and change(terrestrial and aquatic) using animals as indicators and the teaching of underprepared students.
The Department also forms part of the newly established SARChi chair, “Biodiversity value and change in the Vhembe Biosphere Reserve”, housed in the School of Mathematical and Natural Science and Chaired by Prof PJ Taylor. This exciting new development will develop the University of Venda as a vibrant regional hub for biodiversity science, training and conservation action, centred on the Vhembe Biosphere Reserve.
Teach, research and communicate knowledge in the ecology, conservation and management of rural areas with the following thrusts:
· Global change ecology
· Evolutionary Genetics
· Alien invasion
· Freshwater conservation
. Insect Taxonomy
To discover, teach and broadly communicate, knowledge on sustainable rural livelihoods.
· Provide quality training for undergraduate students from previously disadvantaged communities that will enable them to access postgraduate opportunities nationally and internationally at reputable tertiary institutions.
· Maintain a rigorous, broad-based major in biological sciences that provides a compelling learning experience.
· Emphasize general purpose problem solving and analytical abilities that have broad applicability and so foster an ability to adapt to the changing world.
· Emphasize the fundamental building blocks in biology that constitute themes of unification and integration.
· Devise and maintain a non-major instructional program that captures the attention of students and enables them to understand a wide range of contemporary biomedical, biological, medical, and environmental issues.
· Focus research on scarce resources, water and biodiversity in particular.
· Develop strategic liaisons with national and international Universities, research institutions and international conservation organisations.
Communicate contemporary biological science in a compelling way to the public through lectures, workshops, service on boards, outreach to schools, interviews with the media, and other appropriate endeavors.
Inform public policy on the pressing problems of the day (e.g., bio-ethics, environment, evolution) through consultations, service on boards, and related endeavors.
Foster the development of science through service with professional societies, editorial boards, foundations, and funding agencies.
- Advise undergraduates on the structure of their degree programs, research, and careers.

Dr Andrinajoro (Joro) Rakatoarivelo (PhD)
Joro hails from Madagascar and did his PhD on the comparative genetics of bat species on that diverse island. Now, Joro is applying genomics to answer further unresolved issues in African mammal evolution. He is presently investigating incipient speciation of the bushbuck (Tragelaphus scriptus) complex, where ecological drivers are known to drive the evolution genetic structure. Using whole genome sequences Joro will also be looking at the genomic mechanisms of speciation and convergent evolution within closely related spiral-horned antelopes using bioinformatics and coalescent modelling.

Professor Dippenaar-Schoeman retired in 2013 after 46 years as Specialist Scientist and Unit Manager of the Arachnology Unit of the Biosystematics Division, ARC . She still works at the ARC on a part-time basis as a mentor and continues to identify material for students and the SANSA project. She is an extraordinary professor at the University of Pretoria, an association she has held since 2002, and holds an appointment as a Adjunct Professor at the University of Venda. She recently received a B2 rating from the National Research Foundation for the period 2015–2020, independent evidence of her worth and status within the South African and international scientific community. Her research interests are very broad, as demonstrated by her publication list, and include taxonomy and systematics, biodiversity, ecology, biology and predation behaviour of arachnids. She continues to be heavily involved in SANSA activities, publications and identifications. She is presently involved in the first Red Data assessments of South African spiders, one of the required outputs from the SANSA project. This will lead to the publication of an updated atlas on all the spider species of South Africa. She has now time to continue with research on the Thomisidae and is working on a handbook on them.
PROFESSOR DESIRÉ LEE DALTON
Professor Dalton’s research focus is in the field of molecular ecology and her areas of expertise is to determine the genetic integrity of populations and contribute to genetic management of wildlife species in Africa. Her specialization includes marker development and identification and validation of rapid and accurate methods for genetic analysis of species and especially for the field of forensic genetics where reliable, robust and reproducible results are critical. She currently conduct multidisciplinary research on flagship species such as cheetah, pangolin, sungazer and penguin.
PROFESSOR RUSSELL HILL
Professor Hill’s main research interests are in the behavioural ecology of primates and other large mammals and in particular in understanding the decisions animals make about their social and reproductive strategies. In doing so he combines field studies with theoretical analyses based on modelling. He runs the Primate & Predator Project based at the Lajuma Research Centre in the Soutpansberg Mountains, South Africa, and have previously managed other projects in South Africa based at De Hoop Nature Reserve and in the Kruger National Park. His postgraduate students have conducted projects across southern Africa, and increasingly their work is examining mammalian conservation and human-wildlife conflict from an interdisciplinary perspective. He also has interests in applying evolutionary principles to explore a number of different aspects of human behaviour, particularly in understanding the role of the colour red in human competitive interactions.
PROFESSOR NORBERT HAHN
Prof. Norbert Hahn is a biologist resident in the Soutpansberg and is the curator of the Herbarium Soutpansbergensis (ZBP). He is a SACNASP registered Professional Natural Scientist, Botanical Science (400241/14). He has undertaken many scientific studies within the Soutpansberg and southern Africa mainly focused on botany, biogeography, endemism and related disciplines. The results of these studies are published in books, peer reviewed journals and other sources. He has also conducted many surveys for various companies, Government Departments and Universities relating to botany within the Limpopo and North West Provinces. He is one of the founding members of the Vhembe Biosphere Reserve, of which he is presently a board member.

Research Profile and Activities
Evolutionary and Conservation Genetics – Prof Yoshan Moodley
The Department of Zoology has an established bioinformatics and population genetics hub at the University. This platform presently runs several standard bioinformatics pipelines used for the manipulation of next generation sequencing (NGS) data. These include mapping short-read sequences, editing and sorting contigs and multiple genome alignments. We also perform a wide range of evolutionary analyses such as coalescent modelling, Baysesian and likelihood approaches and applied Bayesian computation.
Below is a list of just some of the exciting topics within the fields of evolutionary and conservation genomics research presently carried out at the Moodley lab. We are always on the look out for interested students at the MSc and PhD level, so if you find this kind of work exciting, please get in contact with us. Please also be informed that genetics at the Department of Zoology is not laboratory based. The Department does not have the capability presently to generate NGS data, and so all wet lab data generation is either outsourced or carried out abroad. Our focus is thus highly analytical, and before applying for a postgrad degree in this field, students should be aware that they require a very good understanding of the evolutionary processes that change population allele frequencies and in particular the interplay between the forces of selection and demography.
General research topics (feel free to suggest your own!):
Tracing human migrations using Helicobacter pylori
Speciation using the spiral-horned antelopes (Tragelaphus), prions (Pachyptila) and African rhinoceros (D. bicornis, C. simum) as models
Conservation Genetics: African rhinoceros, mountain zebra, and various other species.
Phylogeography: Pan African studies using widespread species such as the bushbuck as models.
Global change and invertebrates – Prof Stefan Foord
Invertebrates comprise the bulk of biodiversity and contributes most of the ecosystem services humans rely upon. My research group therefore also has disparate taxonomic interests, ranging from termites through to mopane worms. Our main research focus though, s that of invertebrate diversity and their role in ecosystem function in an environment that is rapidly changing. The Vhembe region provides an ideal geographical location to study these changes with contrasting land use practices that vary from the iconic Kruger National Park through to intensive commercial subtropical farming. This together with a rapidly growing human population has undoubtedly resulted in the changes historically never experienced in the region. Our approach in addressing these questions are mainly field-based and experimental with an emphasis on quantitative analysis which vary from network through to multivariate approaches

Aquatic Toxicology – Prof Irene Barnhoorn
The freshwater toxicology research group pays attention to research on endocrine disruption and health effects in aquatic and terrestrial wildlife. Endocrine disrupting chemicals (EDCs) have been defined by the U.S. Environmental Protection Agency (EPA) as “an exogenous agent that interferes with synthesis, secretion, transport, metabolism, binding action, or elimination of natural blood-borne hormones that are present in the body and are responsible for homeostasis, reproduction, and developmental process.” The importance of endocrine disruption studies cannot be overemphasized as EDCs have been considered as carcinogenic, mutagenic and neurotoxic. In South Africa various research groups reported the presence of an array of EDCs in water, sediment and fish tissues. The EDCs that are specifically more harmful are called Persistent Organic Pollutants, or POPs. The list of POPs are enclosed by the Stockholm Convention on Persistent Organic Pollutants. The Stockholm Convention in short as described by UNIDO (United Nations Industrial Development Organization); ”The Stockholm Convention is a global treaty to protect human health and the environment from persistent organic pollutants (POPs). POPs are chemicals that remain intact in the environment for long periods, become widely distributed geographically, accumulate in the fatty tissue of living organisms and are toxic to humans and wildlife. POPs circulate globally and can cause damage wherever they travel. In implementing the Convention, Governments will take measures to eliminate or reduce the release of POPs into the environment. Some of the POPs are included in the pesticides, veterinary drugs and metals reported in fresh water, sediment and fish species.
Research from the past, before 2016, mainly focused on the the story of DDT as the prime endocrine disrupting chemical (EDC) and the impact of contamination in this Vhembe District of South Africa. However other chemicals such as metals, organophosphorus pesticides, polychlorinated biphenyls (PCBs), polycyclic aromatic compounds (PAHs), phenols, personal care products, pharmaceuticals and ARV’s have been found in the water from selected sites in the Luvuvhu River catchment.. Currently the focus is on ARV’s and pharmaceuticals and research projects are ongoing.
1) ARV’s in rivers feeding the Nandoni Dam and the potential fish health effects.
2) Mancozeb in natural water sources in the Vhembe District and the possible endocrine disrupting activity/potential thereof.
3) The concern for human health effects in communities after consumption of fish harvested from the Nandoni Dam in the Luvuvhu River catchment.
4) Antiretroviral drugs (ARVs) in the surface water from a rural area in South Africa and their potential environmental risks
Conservation Ecology of carnivores – Dr Lourens Swanepoel
My current research focuses on issues related to the Conservation Ecology of carnivores. These include the role of mammalian (meso-carnivores) and avian predators play in ecosystem functioning and ecosystem services, the conservation management of carnivores, the density/diversity and distribution of small carnivores, and the ecology of small carnivores inhabiting the agro-ecological matrix. Parallel to these projects I also focus on prey animals for small carnivores, largely small mammals (rodents). Finally, I have recently become interested in the disease component of small carnivores inhabiting human dominated landscapes. I occasionally get involved into projects relating to conservation genetics, social sciences and community based conservation. Our research is field based, however, we also rely on large dataset previously collected. As such prospective MSc students will often only be required to do limited fieldwork and use existing datasets (unless they are independently funded). PhD students should have proven ability to work independently they must have medium to advanced statistical ecology knowledge. We rely heavily on R software and I require that prospective PhD studies have R coding skills, or they should be willing to enroll to online courses to improve skill levels.
