Prof Jon Sadler and Dr Tom Matthews are part of a large team within the Biogeography and Ecology Team at the University of Birmingham. 

Dr Matthews is a Birmingham Fellow who researches global environmental change issues using macroecological, macroevolutionary and biogeographical approaches. He applies a mixture of theoretical and empirical methods to investigate various macroecological topics, including species-area relationships and species abundance distributions. He has a keen interest in island systems and in particular the application of island theory to habitat island systems.

Prof Jon Sadler is a biogeographer and ecologist whose research focuses on species population and assemblage dynamics in animals (sometimes plants). His work is highly interdisciplinary, bisecting biogeography, ecology, urban design, riparian management and island Biogeography.
