Biography
"Graham Alexander is currently working as professor of School of Animal, Plant and Environmental Sciences at University of Witwatersrand. His ideas favor the importance of biotic interactions such as competition and co-evolved interactions within ecological communities; Linking ideas in ecophysiology and biogeography, resulting in exposure of inadequacies in the current conceptual frameworks. Research programme are aimed at using reptiles as model organisms for understanding processes that limit species to particular places and performances. Actively working towards establishing more acceptable research protocols to make the experimentation more powerful in its predictions. As models, he is also targeting species that either have obvious conservation needs, or are vulnerable from a biogeographic perspective. Researching to improve understanding of animal-environment interaction, also to generate clear and applicable management proposals for the conservation of species and ecosystems in South Africa. "
Research Interest
He is expertise in fields such as Landscape and Disturbance Ecology, Phytoremediation, Rehabilitation and Restoration, Ecological modelling and Remote Sensing Zoology and Ecophysiology Herpetology
