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

The sheer number of scientific publications related to greater sage-grouse research can be a challenge for managers to navigate when updating plans for managing greater sage-grouse and sagebrush ecosystems. To assist in this process, the USGS reviewed and summarized scientific literature published since January 1, 2015.
Amphibians—the big-eyed, swimming-crawling-jumping-climbing group of water and land animals that includes frogs, toads, salamanders and worm-like caecilians—are the world’s most endangered vertebrates.
Sharing isn’t always polite, judging by this EarthWord.
Winter feeding of elk in the Greater Yellowstone Ecosystem and its effects on disease dynamics
Providing food to wildlife during periods when natural food is limited results in aggregations that may facilitate disease transmission. This is exemplified in western Wyoming where institutional feeding over the past century has aimed to mitigate wildlife–livestock conflict and minimize winter mortality of elk (Cervus canadensis). Here we review...Cotterill, Gavin G.; Cross, Paul C.; Cole, Eric K.; Fuda, Rebecca K.; Rogerson, Jared D.; Scurlock, Brandon M.; du Toit, Johan T.
On the exchange of sensible and latent heat between the atmosphere and melting snow
The snow energy balance is difficult to measure during the snowmelt period, yet critical for predictions of water yield in regions characterized by snow cover. Robust simplifications of the snowmelt energy balance can aid our understanding of water resources in a changing climate. Research to date has demonstrated that the net turbulent flux (FT)...Stoy, Paul C.; Peitzsch, Erich H.; Wood, David; Rottinghaus, Daniel; Wohlfahrtd, Georg; Goulden, Michael; Ward, Helen
Annotated bibliography of scientific research on greater sage-grouse published since January 2015
The greater sage-grouse (Centrocercus urophasianus; hereafter GRSG) has been a focus of scientific investigation and management action for the past two decades. The 2015 U.S. Fish and Wildlife Service listing determination of “not warranted” was in part due to a large-scale collaborative effort to develop strategies to conserve GRSG populations...Carter, Sarah K.; Manier, Daniel J.; Arkle, Robert S.; Johnston, Aaron N.; Phillips, Susan L.; Hanser, Steven E.; Bowen, Zachary H.
