Jeremy Kerr of the University of Ottawa, a consultant for the Canadian government about species at risk of extinction, describes his work mapping change on a macro scale. Dr. Kerr argues that this kind of science is becoming more relevant in the context of climate change. His particular research interest is butterflies, and his lab recently launched the website "ebutterfly," where ordinary citizens can contribute to ecological science by logging in data about butterfly sightings. Kerr's lecture was this year's Paul L. Errington Memorial Lecture at ISU. Errington was an Iowa State College scientist whose 1957 book, Of Men and Marshes, is in the same class of work as Aldo Leopold's Sand County Almanac.
