2020 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.

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.

Boreal toad survival data in relation to Bd status and community composition

These data represent capture mark recapture data from toads, and results of testing for Bd (Batrachochytrium dendrobatidis) the pathogen that causes amphibian chytridiomycosis on individuals. The data span from 2004-2016 at three sites in Montana where boreal toads were declining. The data also include temperature measurements at the sites and information on the egg counts and Bd prevalen...

2019 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.

Glacier National Park alpine stream sampling watersheds, 2011-2013

The dataset “Glacier_National_Park_alpine_stream_sampling_watersheds,_2011-2013.shp” is a GIS shapefile of the drainage areas of each of the 129 alpine and glacial aquatic macroinvertebrate collection sites included in an analysis to test the prediction that glacier retreat reduces biodiversity in mountain ecosystems through the loss of uniquely adapted meltwater stream species

Glacier National Park alpine aquatic invertebrates, 2011-2013

Table of habitat data, including location coordinates and upstream glacial coverage for aquatic macroinvertebrate sampling sites. Data used for analysis of macroinvertebrate samples collected from alpine and glacial streams in Glacier National Park.

Minimum snow and ice coverage for GNP, 2003-2015

To determine minimum coverage of perennial snow and ice cover for Glacier National Park, the minimum extent of glaciers and multi-year snow features were digitized from satellite imagery (10-meter NAPP 2003, NAIP 2005, and NAIP 2013, and 30-cm resolution, multispectral, pansharpened Digital Globe WorldView satellite imagery collected in late summer and fall 2015). Features were di

Soil sample locations for chronic wasting disease prion surveillance in Grand Teton National Park and National Elk Refuge 2019

A total of 200 soil samples were collected in the Greater Yellowstone Ecosystem in Grand Teton National Park and the National Elk Refuge in July 2019 for chronic wasting disease (CWD) monitoring purposes. To collect samples from locations where ungulates are most likely to be shedding or encountering CWD, we targeted elk collar data locations, known migration routes of mule deer and elk%2

Microsatellite data for American bullfrogs in the Yellowstone River Montana, 2013-2017

We used 7 microsatellites to characterize the invasion genetics of 528 American bullfrogs sampled from the Yellowstone River floodplain (Montana). American bullfrog samples were collected from a 140 km section of the Yellowstone River near Billings, MT in 2013 - 2017.

Environmental DNA robotic and manual sampling data, Yellowstone and Snake Rivers, 2017-2019

Environmental DNA detection results from samples collected using autonomous water sampling robots and manual approaches. Samples were collected in the Upper Yellowstone River (Montana) and Upper Snake River (Idaho/Wyoming) in 2018 and 2019. Samples were tested for the DNA of the following species: the waterborne protozoa Naegleria spp., the fish pathogen Tetracapsuloides bryosalmo
