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.

As part of ongoing efforts required under the 2016 Yellowstone Grizzly Bear Conservation Strategy to monitor the population of grizzly bears in the Yellowstone Ecosystem, the Interagency Grizzly Bear Study Team (IGBST) captures and monitors grizzly bears for research and monitoring purposes. Here you will find capture notifications for the 2018 field season.

Long-term population dynamics and conservation risk of migratory bull trout in the upper Columbia River Basin
Conservation of migratory and sensitive fish like bull trout will require ecosystem level approaches that target stressors in headwater spawning and rearing habitats as well as critical habitats in rivers and lakes used during juvenile and adult life stages.
Estimating distemper virus dynamics among wolves and grizzly bears using serology and Bayesian state‐space models
Many parasites infect multiple hosts, but estimating the transmission across host species remains a key challenge in disease ecology. We investigated the within and across host species dynamics of canine distemper virus (CDV) in grizzly bears (Ursus arctos) and wolves (Canis lupus) of the Greater Yellowstone Ecosystem (GYE). We hypothesized that...Cross, Paul C.; van Manen, Frank T.; Viana, Mafalda; Almberg, Emily S.; Bachen, Daniel; Brandell, Ellen E.; Haroldson, Mark A.; Hudson, Peter J.; Stahler, Daniel R.; Smith, Douglas W.
International meeting on sarcoptic mange in wildlife, June 2018, Blacksburg, Virginia, USA
Sarcoptic mange is a globally distributed disease caused by the burrowing mite Sarcoptes scabiei, which also causes scabies in humans. A wide and increasing number of wild mammal species are reported to be susceptible to mange; however, the impacts of the disease in wildlife populations, mechanisms involved in its eco-epidemiological dynamics...Astorga, Francisca; Carver, Scott; Almberg, Emily S.; Sousa, Giovane R.; Wingfield, Kimberly; Niedringhaus, Kevin D.; Van Wick, Peach; Rossi, Luca; Xie, Yue; Cross, Paul C.; Angelone, Samer; Gortázar, Christian; Escobar, Luis E.
Local topography increasingly influences the mass balance of a retreating cirque glacier
Local topographically driven processes – such as wind drifting, avalanching, and shading – are known to alter the relationship between the mass balance of small cirque glaciers and regional climate. Yet partitioning such local effects from regional climate influence has proven difficult, creating uncertainty in the climate representativeness of...Florentine, Caitlyn; Harper, Joel T.; Fagre, Daniel B.; Moore, Johnnie; Peitzsch, Erich H.
