Detailed Description

Chris is a graduate mentor for the Doris Duke Conservation Scholars Program (Chris 2nd from right, all other Doris Duke students). Prior to his time at the University of Arizona he worked with the Oregon Department of Fish and Wildlife and completed his undergraduate degree at Oregon State University. Chris's research, in collaboration with the U.S. Forest Service, focuses on assessing native and nonnative fish habitat use on two ‘Wild and Scenic’ rivers of central Arizona. On the Verde River, following the largest flooding event of the past decade Chris investigated pre- and post-flood fish abundance, population structure, and habitat use of both native and nonnative fishes. My research found native fishes, rare in this stretch of river, to increase 40-fold following flood, suggesting a successful spawning event. On Fossil Creek, Chris evaluated native fish habitat use and how that may shift in the presence of a nonnative piscivore, specifically smallmouth/redeye bass. Chris conducted snorkel surveys both upstream and downstream of an artificial fish barrier to evaluate Roundtail Chub, Sonora Sucker, Desert Sucker, and Speckled Dace use of micro- and macro- habitats, both in the presence and absence of nonnative piscivores.
