Dung beetles likely date back to Africa some 40 million years ago. They then spread across the world, except to Antarctica. Most dung beetles feed on dung. They lay their eggs in dung balls that are buried underground so that their developing larvae have enough food and easy access to it. Their digging helps to nourish and loosen the soil, and improves its water-holding capacity.

Christian Deschodt is a PhD student in the University of Pretoria’s (UP) Invertebrate Biosystematics and Conservation Group under the supervision of Professor Catherine Sole. He completed a master’s degree at Rhodes University and has been doing research at UP for 15 years, and since 2020 as a doctoral student.
Deschodt has expert knowledge of the southern African Scarabaeinae, more widely known as the dung beetle.
As to how his field of research contributes to the betterment of the world, he says: “Without dung beetles, within one year, the earth would literally be knee-deep in excreted matter. Dung beetles are of extreme ecological importance, and can be used as indicators of environmental health. I hope that my knowledge will help us to better understand the natural distribution of the Scarabaeinae so we can improve or concentrate our conservation efforts of new or established reserves and ecosystems where needed.”
In the recent past, Deschodt has authored or co-authored 41 peer-reviewed papers in local and international journals, as well as a peer-reviewed book, on taxonomy and ecology. He is part of the International Union for Conservation of Nature’s specialist group on dung beetles which assesses the southern African fauna for the IUCN’s Red List of Threatened Species.
Outside his academic work, Deschodt is a beekeeper and keeps a few head of Braunvieh cattle. He has an extensive collection of books on the natural history of Africa and southern Africa, some of which form part of the rare Africana book collection.
Professor Catherine Sole's research is driven by the power of molecular techniques in testing evolutionary processes at various levels: population, species and higher taxa with special focus on invertebrates. She aims to find common evolutionary patterns in different taxa that reflect landscape and phylogenetic changes; and linking them to climatic, biogeographic and geological changes.
She is affiliated with the University of Pretoria Forestry and Agricultural Biotechnology Institute (FABI) to which she contributes entomological capacity and expertise.
University of Pretoria (UP) researchers have found that the antioxidant content of certain types of tea can be likened to that found in recommended portions of fruit and vegetables.
Half a cup of black tea, oolong tea or green tea contained the same amount of antioxidants with radical scavenging capabilities (RSC) as that of a 200mg vitamin C tablet.
Researchers at the University of Pretoria (UP) may have identified the gene that is responsible for diet-related obesity. By exploring the role of the novel gene Slc7a8, they have made a potential breakthrough in current knowledge about the cellular mechanisms that drive fat accumulation. This understanding is crucial in developing effective treatments.
