• Lateglacial climate and vegetation change
• Disturbance ecology: fire and forest moth pest histories
• Ecosystem tipping points
Les C. Cwynar obtained his BSc, MSc and PhD (1980) all from the University of Toronto, yet shows no signs of inbreeding to date. He is a former President of the Canadian Quaternary Association and has served on international committees to define and subdivide the Holocene Epoch, our current interglacial period. He uses the techniques of pollen, plant macrofossil, charcoal, chironomid, and moth scale analyses to answer questions about treeline history, Beringian paleoecology, and disturbance ecology (fire and forest moth pests), with a foucus on lateglacial environmental change.
