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. It uses approaches that combine detailed field studies, field and laboratory experimentation, sometimes with social science to examine the links between environmental variability and species (including humans) responses. His research has significant blue skies and applied implications for understanding and responding to the impacts of climate and environmental change variability on urban and island ecosystems, hydrological systems, riparian/riverine ecology, the management/conservation of freshwaters. He is a fan of numbers and coding (especially using open source software such as R).


Jon Sadler joined the School in 1993 having worked as a Leverhulme Trust postdoctoral Research Fellow (1991-1993) examining aspects of the impact of volcanic eruptions on ecological systems at Sheffield University. Previously he had completed a PhD  on the Biogeography of invertebrates in the North Atlantic Islands in Sheffield (1991) and a MSc (1987) and BSc (1985) in Birmingham. He is a fellow of the Royal Entomological Society, Fellow of the Royal Geographical Society, member of the British Ecological Society and a Deputy-Chief-Editor of the Journal of Biogeography.
