Alpine Vegetation Trends in Glacier National Park, Montana 2003-2018

This dataset is focused on alpine plant species presence/absence, species turnover, and trends in species abundance on four mountain summits in Glacier National Park, Montana, USA from 2003 through 2014. Two summit sites were established in 2003 on Dancing Lady and Bison Mountain, east of the continental divide. Two additional summit sites were established in 2004 on Pitamakin and Mt.

Environmental DNA results from dreissenid mussel early detection surveys in Montana, Minnesota, and Wisconsin 2017-2018

Positive and negative dreissenid mussel DNA quantitiative PCR results from environmental DNA water samples collected in Montana, Wisconsin and Minnesota to assess if environmental DNA can extend the seasonal window for dreissenid mussel early detection.

Bat occupancy model predictions for Montana from acoustic and mist net data 2008-2010

The spread of white-nose syndrome (WNS) across the eastern United States has raised conservation concerns and provided motivation for efforts to monitor the impacts of this disease. Currently, WNS has not yet been detected in Montana, or any other western state besides Washington, and it is unknown how severe it will impact species in this region once it arrives. Within an occupancy mod

Dreissenid mussel eDNA results for streamgage water samples in the Columbia and Colorado River basin

Environmental DNA results for water samples collected at USGS streamgages in the Columbia and Colorado river basins. Water samples were collected by USGS hydrologic technicians May - September 2018 and analyzed for presence of dreissenid mussel DNA. In this dataset, we report quantitative PCR results for each streamgage locations.

West Green River elk herd locations in southwestern Wyoming, 2005-2010

Between 2005 and 2010, 61 adult female elk were trapped using a baited corral trap on Fossil Butte National Monument during winter. An additional 12 female elk were darted from a helicopter during the winter of 2007 near Cokeville, WY, located approximately 20 km northwest of the Monument. We affixed all elk with GPS collars programmed to collect location data every 5 hours. In total we col...

Fish eDNA results for streamgage water samples in the Columbia and Colorado River basins

Environmental DNA results for water samples collected at USGS streamgages in the Columbia and Colorado river basins. Water samples were collected by USGS hydrologic technicians May - September 2018 and analyzed for presence of kokanee and yellow perch DNA. In this dataset, we report results and applicable covariates associated with each streamgage locations. This is version 1.1 of this data...

2017 Known and Probable Grizzly Bear Mortalities in the Greater Yellowstone Ecosystem

Identifying the locations and causes of grizzly bear mortality is another key component in understanding the dynamics of this population. Over 80% of all documented bear mortalities are human-caused. Tracking human-caused bear deaths helps define patterns and trends that can direct management programs designed to reduce bear mortality.

Individual specific hybridization data from the upper Snake River, Wyoming from 2014

Dataset includes spatial location of samples sites and individidual-specific genetic data describing the extent of hybridization between Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and rainbow trout (O. mykiss) in Wyoming.

Canine distemper virus antibody titer results for grizzly bears and wolves in the Greater Yellowstone Ecosystem 1984-2014

We investigated the dynamics of canine distemper virus (CDV) in grizzly bears (Ursus arctos) and wolves (Canis lupus) of the Greater Yellowstone Ecosystem (GYE) using serological data collected from 1984 to 2014. 565 sera samples were obtained from 425 unique grizzly bears (134 females and 291 males) from 1984 to 2014 and 319 sera samples were obtained from 285 unique wolves %
