Jaime Leigh Johnson

PhD candidate in the Department of Biodiversity and Conservation Biology, University of the Western Cape
I am currently a PhD candidate working under the supervision of Dr Anusha Rajkaran at the University of the Western Cape. The aim of my PhD research is to characterize the prevalence and distribution of selected pollutants within mangrove dominated estuarine systems in the Eastern Cape, South Africa. We believe that this will give us a better understanding of the role of these habitats play in accumulating and/or filtering anthropogenic pollutants. Before joining the University of the Western Cape, I completed a Masters in Science at Nelson Mandela University under the supervision of Prof. Janine Adams and Dr Jacqueline Raw. My Masters project produced the first report on carbon storage in a warm-temperate mangrove forest in South Africa. Prior to this I completed both my BSc honours and BSc undergraduate degrees at Nelson Mandela Metropolitan University. I am most certainly a mangrove enthusiast, however my research interests includes mangrove ecosystem function ecology and function, estuarine ecology, shallow water ecosystems, climate change and blue carbon.
