Stephen J. Mayor is a research scientist at the Ontario Forest Research Institute, as well as a Adjunct Professor at the University of Toronto. He currently leads the Terrestrial Systems Ecology Research Program, which investigates the cumulative effects of climate change, associated natural disturbances, and anthropogenic disturbances on forest dynamics and ecological integrity. The research program integrate approaches from biodiversity science, biogeography, macroecology, conservation biology, community ecology, ecoinformatics, and ecological scaling. He and his team aim broadly to contribute to answering fundamental ecological questions, often with relevant societal applications to issues like land use and forest management planning, conservation, and climate change. As good science begins with good data and methods, they invest in sound database development including refined spatiotemporal disturbance mapping, and methodological developments in model integration.
