Paul A. Knapp

Paul A. Knapp
Professor


Ph.D. Georgia, 1989
Biogeography, climatology, dendroecology

Dr. Knapp's academic interests include biogeography, climatology, and dendroecology with a regional focus in the American West. Dr. Knapp's research has focused on examining the influence of atmospheric CO2 enrichment on the growth rates of woody species in arid and semiarid environments, and the paleoclimatology of the interior Pacific Northwest.
