My
research program explores how grazing animals modify ecosystems,
how different environmental factors control biodiversity, and how
human-caused modifications of carbon dioxide and nitrogen in the
air affect terrestrial ecosystems. Over the past few years, my students
(both graduate and undergraduate) and I have worked with large grazing
mammals, grasshoppers, leafhoppers, spiders, lizards, salamanders,
grasses and trees at several interesting places, including southwestern
and northern Utah, Minnesota, and South Africa.
