Ready to remove from the trap
May 9, 2018

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) traps and monitors grizzly bears for research and monitoring purposes. Here you will find trapping notifications for the 2018 field season.

Bull trout in the Flathead River.
April 4, 2018

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.

Examining speed versus selection in connectivity models using elk migration as an example

ContextLandscape resistance is vital to connectivity modeling and frequently derived from resource selection functions (RSFs). RSFs estimate relative probability of use and tend to focus on understanding habitat preferences during slow, routine animal movements (e.g., foraging). Dispersal and migration, however, can produce rarer, faster movements...

Effects of brine contamination from energy development on wetland macroinvertebrate community structure in the Prairie Pothole Region

Wetlands in the Prairie Pothole Region (PPR) of North America support macroinvertebrate communities that are integral to local food webs and important to breeding waterfowl. Macroinvertebrates in PPR wetlands are primarily generalists and well adapted to within and among year changes in water permanence and salinity. The Williston Basin, a major...
