Northern Rocky Mountain Science Center (NOROCK)
This is our office.
These are our coworkers.
This is our rush hour.
This is our happy hour.
We hope you will enjoy learning about the variety of ecosystems and species we are studying throughout the United States. Our scientists work on diverse issues such as fish and wildlife conservation, invasive species and wildlife disease, energy development, climate and ecosystem change, and much more. Click on Science to begin exploring the places we go and the species and landscapes we study.
NOROCK EcoLunch is a forum for students, researchers, visiting scientists and collaborators in the environmental sciences to present their current and past work.Upcoming Talk

Western waters support some of the most intact aquatic ecosystems in North America, yet invasive species and emerging infectious diseases pose significant and immediate threats to these ecosystems.
Vegetation responses to sagebrush-reduction treatments measured by satellites
Time series of vegetative indices derived from satellite imagery constitute tools to measure ecological effects of natural and management-induced disturbances to ecosystems. Over the past century, sagebrush-reduction treatments have been applied widely throughout western North America to increase herbaceous vegetation for livestock and wildlife....Johnston, Aaron N.; Beever, Erik; Merkle, Jerod A.; Chong, Geneva W.
Demographic modelling reveals a history of divergence with gene flow for a glacially tied stonefly in a changing post-Pleistocene landscape
AimClimate warming is causing extensive loss of glaciers in mountainous regions, yet our understanding of how glacial recession influences evolutionary processes and genetic diversity is limited. Linking genetic structure with the influences shaping it can improve understanding of how species respond to environmental change. Here, we used genome-...Hotaling, Scott; Muhlfeld, Clint C.; Giersch, J. Joseph; Ali, Omar; Jordan, Steve; Miller, Michael R.; Luikart, Gordon; Weisrock, David W.
Hydroclimatology of the Missouri River basin
Despite the importance of the Missouri River for navigation, recreation, habitat, hydroelectric power, and agriculture, relatively little is known about the basic hydroclimatology of the Missouri River basin (MRB). This is of particular concern given the droughts and floods that have occurred over the past several decades and the potential future...Wise, Erika K.; Woodhouse, Connie A.; McCabe, Gregory; Pederson, Gregory T.; St. Jacques, Jeannine-Marie
