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. We are part of the Northwest Region of the USGS and our scientists work on diverse issues such as wildlife health, invasive species, climate, endangered species and much more.

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.
NOROCK EcoLunch is a forum for students, researchers, visiting scientists and collaborators in the environmental sciences to present their current and past work. Presentations will range from brown bag discussions of ongoing projects to more formal seminar presentations.
A new U.S. Geological Survey study provides a larger window into the future for understanding how seasonal stream temperatures may change in one of the most ecologically diverse ecosystems in North America – the Crown of the Continent Ecosystem, USA and Canada.
Linking spring phenology with mechanistic models of host movement to predict disease transmission risk
Disease models typically focus on temporal dynamics of infection, while often neglecting environmental processes that determine host movement. In many systems, however, temporal disease dynamics may be slow compared to the scale at which environmental conditions alter host space-use and accelerate disease transmission.Using a mechanistic movement...Merkle, Jerod A.; Cross, Paul C.; Scurlock, Brandon M.; Cole, Eric K.; Courtemanch, Alyson B.; Dewey, Sarah R.; Kauffman, Matthew J.
A probe-based quantitative PCR assay for detecting Tetracapsuloides bryosalmonae in fish tissue and environmental DNA water samples
A probe-based quantitative real-time PCR assay was developed to detect Tetracapsuloides bryosalmonae, which causes proliferative kidney disease in salmonid fish, in kidney tissue and environmental DNA (eDNA) water samples. The limits of detection and quantification were 7 and 100 DNA copies for calibration standards and T. bryosalmonae...Hutchins, Patrick; Sepulveda, Adam; Martin, Renee; Hopper, Lacey
Climate change and alpine stream biology: progress, challenges, and opportunities for the future
In alpine regions worldwide, climate change is dramatically altering ecosystems and affecting biodiversity in many ways. For streams, receding alpine glaciers and snowfields, paired with altered precipitation regimes, are driving shifts in hydrology, species distributions, basal resources, and threatening the very existence of some habitats and...Hotaling, Scott; Finn, Debra S.; Giersch, J.
