Williams Lectures at Ecological Society of America


Ernest Williams
Ernest Williams
Ernest Williams, the Christian A. Johnson Excellence in Teaching Professor of Biology, recently attended the annual meeting of the Ecological Society of America in Albuquerque, N.M, where he gave a talk titled "Habitat change and population loss and gain in a montane butterfly." This talk summarized research he has conducted over the past 25 years on Gillett's Checkerspot butterfly in the Rocky Mountains; the distribution of this species has changed as the meadows they inhabit have been altered by climate change, forest fire, and vegetative succession.

Also, Williams had an article published in American Butterflies (vol. 17, pages 4-13; summer 2009 issue) titled "Lifestyles of the scaled and beautiful: Pearl and Northern Crescents." For a number of years, Williams and students have conducted research on Pearl Crescent butterflies and their host plants, with parallel studies being run from a chemical viewpoint by Silas D. Childs Professor of Chemistry Robin Kinnel and his students.
