Robert Gresswell

Emeritus Research Biologist

Department: Northern Rocky Mountain Science Center

University System: USGS - Bozeman


Professional Summary:

I am an emeritus research biologist and affiliate assistant professor in the Department of Ecology at Montana State University. My research is focused on the factors that influence fish abundance, distribution, and life history within, and among watersheds, and how these relationships change in through time. My interest in the role of disturbance in shaping the aquatic systems has led to research on the interactions among landscape-scale environmental features, instream habitat characteristics, and cutthroat trout abundance and distribution. Currently, my research is focused on the effects of fire, timber harvest, invasive species, and climate change on the persistence of native trout in the Intermountain West. I have been involved with the lake trout issue in Yellowstone Lake since these invaders were first discovered in 1994 and act as chair of the lake trout suppression independent scientific review panel that was formed in 2008.
