Prof Andrew McKechnie of the Department of Zoology and Entomology was recently awarded the South African Research Chair in Conservation Physiology. The Chair is hosted by the National Zoological Gardens of South Africa and co-hosted by the University of Pretoria (UP).
The University of Pretoria's Dr Pieter Olivier is part of an international collaboration whose work was recently published in Nature. The study highlights how biodiversity is changing as a result of deforestation.
