CMIP5 MACAv2-METDATA Monthly Water Balance Model Projections 1950-2099 for the Contiguous United States

We apply a monthly water-balance model (MWBM) to simulate components of the water balance for the period 1950-2099 under RCP4.5 and RCP8.5 for the Contiguous United States. We use the statistically downscaled MACAv2-METDATA temperature and precipitation data from 20 General Circulation Models (GCMs) from the Climate Model Intercomparison Program Phase 5 (CMIP5) as input to the water balance model.

A network of eight naturalized streamflow reconstructions for the Milk and St Mary Rivers spanning years 1017 - 1998 CE

Paleohydrologic records provide a valuable perspective on the variability of streamflow and hydroclimate that is critical for water resource planning and placing present day and future conditions into a long-term context. Until now, key insights gained from streamflow reconstructions in the other river basins across the Western U.S. have been lacking in the Milk and St. Mary River Basin. Here we u

Remotely sensed elk locations on the National Elk Refuge, Wyoming, 2017-2019

Remotely sensed elk locations were derived from satellite and Unmanned Aerial Systems (UAS) imagery collected during the winter of 2018 and the winter and spring of 2019 at the National Elk Refuge in Jackson, Wyoming and compared to locations from Global Positioning System (GPS) collars from 2017 - 2019. This data release provides the source, date, time, latitude, and longitude of elk locations an

Environmental DNA data, fish abundance data, and stream habitat data from northwest Montana and northeast Washington and southern British Columbia, Canada

Field estimates of the abundance of two trout species (bull trout and westslope cutthroat trout) in Montana and rainbow trout in Washington and British Columbia were collected in concert with environmental DNA samples (eDNA) to evaluate if eDNA copy numbers correlated with abundance of trout. In addition, stream habitat data including channel units (pools, riffles), substrate, large woody debris,

Time to removal of fetal materials by scavengers in SW Montana 2017 - 2018

We investigated the time to removal of bovine fetal materials, meant to simulate elk abortion materials, by scavengers in southwest Montana at 233 sites in February – June 2017 and 2018. Scavengers are likely to reduce the transmission risk of brucellosis, a bacterial disease that can lead to reproductive failure in infected elk, by consuming and removing infectious fetal materials from the landsc

Rangewide summertime model predictions for three bat species (Myotis lucifigus, Myotis septentrionalis, and Perimyotis subflavus) from acoustic and mist net data 2010 to 2019

False positive occupancy analysis predictions with model uncertainty based on summertime data provided to support the three bat species status assessment (SSA) for Myotis lucifigus (MYLU), Myotis septentrionalis (MYSE), and Perimyotis subflavus (PESU). The objectives outlined by the Fish and Wildlife Service's SSA team were to estimate summertime distributions across the entire species range. Stat

Quantitative polymerase chain reaction detection data for controlled DNA contamination experiments

This data shows the quantification cycle at which fluorescence signals crossed a threshold fluorescence for samples analyzed as part of controlled experiments to determine whether contaminating DNA is present in samples under varying experimental conditions.

Alpine Vegetation Trends in Glacier National Park, Montana 2019

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. This dataset consists of data from 2019, the fourth survey of the project which is on a five year survey schedule. Two summit sites were established in 2003 on Dancing Lady and Bison Mountain, east of the continental di

Data release for Greater Yellowstone Climate Assessment (vol 1), Chapter 7. Future Water Projections for the GYA

We apply a monthly water-balance model (MWBM) to simulate components of the water balance for the period 1950-2099 under RCP4.5 and RCP8.5 for the Greater Yellowstone Climate Assessment. We use the statistically downscaled MACAv2-METDATA temperature and precipitation data from 20 GCMs from the Climate Model Intercomparison Program Phase 5 (CMIP5) as input to the water balance model. The statistica

Glaciers of Glacier National Park Repeat Photography Collection

The “Glaciers of Glacier National Park Repeat Photography Collection” is a compilation of photographs documenting the retreat of glaciers in Glacier National Park, Montana, U.S.A. (GNP) through repeat photography. The collection is comprised of 58 image pairs, resulting from twenty-two years of U.S.Geological Survey (USGS) field excursions (1997-2019) for the purpose of photographically documentin

T. bryosalmonae detection in fish and water, DNA sequence, and simple sequence repeat data collected in the Inter-Mountain West from 2011 to 2019

This data release contains molecular diagnostic results and molecular detection of the myxozoan parasite Tetracapsuloides byrosalmonae in fish tissue and environmental DNA samples collected from the inter-mountain West, USA.

Western bumble bee predicted occupancy and detection probability rasters for the western continental United States from 1998 to 2018

These data represent occupancy estimates for western bumble bee across the western continental United States and the spatial variation in detection probabilities that occur during bumble bee surveys. This product contains five raster layers (appearing as separate bands in a multi-band raster). The first two bands represent the predicted occupancy of western bumble bee in 1998 and 2018. We modeled
