Prof Radloff

Prof Frans Radloff - Associated Professor, PhD (Botany), MSc in Zoology, BSc (Hons) in Wildlife Management, BSc Aric (Animal and Pasture Sciences)

I have been working in the Department of Conservation and Marine Sciences at CPUT since 2011 where I co-ordinate the Work Integrated Learning year for the Nature Conservation programme. I also teach at both undergraduate and Advance Diploma level. Eight Master’s degree students have completed their studies under my supervision and three more is currently registered.

My research interests lie within community ecology and ecosystem functioning.  I am particularly interested in what drives animal distribution patterns, and how animals influence and shape ecosystems by means of herbivory and predation. Understanding these dynamics is imperative for the development of sound wildlife management practices and conservation strategies. I use stable isotope analysis and camera traps extensively in my research. See for more detail on my research.
