Northern Rocky Mountain Science Center (NOROCK)
Home
Our Northern Rocky Mountain Science Center's priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices. If you need additional assistance, please contact Claudia Regan at cregan@usgs.gov or Judy O'Dwyer at jodwyer@usgs.gov.

Detecting Invasive and Rare Species with the National Streamflow Network
Two recently published papers suggest the integration of environmental DNA, or eDNA, sampling at select National Streamflow Network streamgages in the U.S. Northwest is feasible.
tIGBST Public Notifications and Resources
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 2019 field season.

Amphibian chytrid prevalence on boreal toads in SE Alaska and NW British Columbia: Tests of habitat, life stages, and temporal trends
Tracking and understanding variation in pathogens such as Batrachochytrium dendrobatidis ([Bd]), which causes amphibian chytridiomycosis and has caused population declines globally, is a priority for many land managers. However, there has been relatively little sampling of amphibian communities at high latitudes. We used skin swabs collected...
Hossack, Blake R.; Adams, Michael J.; Honeycutt, R Ken; Belt, Jami J; Pyare, S A round-robin evaluation of the repeatability and reproducibility of environmental DNA assays for dreissenid mussels
Resource managers may be hesitant to make decisions based on environmental (e)DNA results alone since eDNA is an indirect method of species detection. One way to reduce the uncertainty of eDNA is to identify laboratory‐based protocols that ensure repeatable and reproducible results. We conducted a double‐blind round‐robin analysis of probe‐based...
Sepulveda, Adam J.; Hutchins, Patrick R.; Jackson, Craig; Ostberg, Carl; Laramie, Matthew; Amberg, Jon J.; Counihan, Timothy; Hoegh, Andrew B.; Pilliod, David Species-specific responses to wetland mitigation among amphibians in the Greater Yellowstone Ecosystem
Habitat loss and degradation are leading causes of biodiversity declines, therefore assessing the capacity of created mitigation wetlands to replace habitat for wildlife has become a management priority. We used single season occupancy models to compare the occurrence of larvae of four species of pond‐breeding amphibians in wetlands created for...
