I am an ecologist, with a specific interest in the interactions between ecology and geomorphology and I hold a C2 rating from the NRF. The main thread connecting my research is ecological disturbance, both anthropogenic and natural disturbance. As such, I have student projects focusing on the effect of disturbances (road construction, burrowing, plant invasion) on species richness and composition of both plants and animals. I have also recently expanded my interest to include ecological disturbances within an agricultural context, broadening the scope and applicability of my research and facilitating projects also within the social sciences. My research interests have naturally evolved over the years into what I would call three main streams of interest, within this overarching umbrella of ecological disturbance. My main research interest is on burrowing mammals, their ecological impacts and their interactions with the farming community in South Africa. I have had a number of students graduate on this topic, both within the natural sciences and the humanities. I am also interested in the ecological effects of roads, as an anthropogenic disturbance. Although I have not published on this topic yet, I have supervised a number of projects on roadside ecology, and hope to publish some of the results in the near future. My third interest is not so much a disturbance in itself, as a response to disturbance. As such, I am particularly interested in the response of seedbanks, and the similarity between seedbanks and aboveground vegetation, to disturbance. Seedbank ecology has thus formed a central theme in many of my publications.
