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.
An Integrated Framework for Ecological Drought Across Riverscapes of North America
Climate change is increasing extreme droughts events, posing a threat to freshwater ecosystems, particularly with human demands for diminishing water supplies.

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 Whitebark pine (Pinus albicaulis) growth and defense in response to mountain pine beetle outbreaks
Whitebark pine (Pinus albicaulis) is a critical forest species of Northern Rocky Mountain upper subalpine ecosystems, yet little is known about the physiological response of whitebark pine to disturbance (e.g. fire, bark beetles, and pathogens) across a range of diverse environmental gradients. Resin–based defenses have long been recognized as the...

Glacier retreat in Glacier National Park, Montana
Currently, the volume of land ice on Earth is decreasing, driving consequential changes to global sea level and local stream habitat. Glacier retreat in Glacier National Park, Montana, U.S.A., is one example of land ice loss and glacier change. The U.S. Geological Survey Benchmark Glacier Project conducts glaciological research and collects field...
