• Evaluation of anthropogenic disturbance on African clawless otter (Aonyx capensis) physiological stress, behaviour, and population density using non-invasive methods 

  Majelantle, Tshepiso Lesedi (University of Pretoria, 2019)

  Land transformation for anthropogenic use is the leading cause of species declines globally, but some species are able to succeed in these environments. African clawless otters (Aonyx capensis) are the most widely ...
• Development of novel surveillance tools for rapid detection of citrus psyllids 

  Pullock, Dylan Andrew (University of Pretoria, 2024)

  South Africa’s citrus industry is lucrative but its profitability is threatened by pest insects, either due to direct damage or via the transmission of pathogens causing disease that negatively impact citrus production. ...
• The effects of climate change on freshwater fauna in the lower Olifants River, South Africa 

  Adlam, Amanda Laura (University of Pretoria, 2024)

  Freshwater rivers are under threat worldwide from anthropogenic disturbances including climate change. Climate change will increase air temperature and, consequently, water temperature in rivers. The survival of aquatic ...

  Ashmore, Jade Sabrina (University of Pretoria, 2024-03-21)

  Literature review of insect sex determination pathway and CRISPR/Cas9 gene editing tool in application for genetic-based pest control methods. The de novo genome of Gonipterus sp. n. 2 was sequenced with long and short ...
• Assessing longitudinal profiles of glucocorticoid concentrations in the baleen of male and female southern right whales ( Eubalaena australis) 

  Pieterse, Estefan (University of Pretoria, 2024-07-08)

  Marine mammals are subject to a variety of anthropogenic and natural stressors. However, it is still poorly understood how these stressors may affect physiological adaptations including affecting reproductive biology. ...
• Cellular- and symbiont-mediated defenses in Bactrocera dorsalis (Hendel) and Ceratitis cosyra (Walker) against their native and introduced parasitoids 

  Gwokyalya, Rehemah (University of Pretoria, 2024-07-08)

  The use of parasitoids as pest biological control agents has been adopted globally. Nonetheless, the success of parasitoid-oriented biological control programs is dependent on the virulence of the parasitoid, a phenomenon ...
• The role of termites in South African savanna ecology 

  Bunney, Katherine (University of Pretoria, 2023-07-08)

  Termites are ecosystem engineers that influence savannas through the process of decomposition and bioturbation (movement of soil by biota). Firstly, decomposition is the process by which dead plant biomass is recycled and ...
