With increasing concerns about the impact of warming temperatures on water resources, more attention is being paid the relationship between runoff and precipitation, or runoff efficiency. Temperature is a key influence on Colorado River runoff efficiency, and warming temperatures are projected to reduce runoff efficiency. Here, we investigate the nature of runoff efficiency in the upper Colorado River (UCRB) basin over the past 400 years, with a specific focus on major droughts and pluvials, and to contextualize the instrumental period. We first verify the feasibility of reconstructing runoff efficiency from tree-ring data. The reconstruction is then used to evaluate variability in runoff efficiency over periods...

The focus of this dataset is soil temperature collected on four mountain summits in Glacier National Park, Montana, USA from 2003 through 2018. 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. Seward, also east of the continental divide. These four summit sites comprise a target region set up in accordance with the Global Observation Research Initiative in Alpine Environments (GLORIA). GLORIA was initiated by the University of Vienna in 2000 and protocols for operating target regions have been refined and revised since then. Sixty-nine GLORIA target regions now exist throughout the...

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 (130 females and 155 males) from 1996 to 2014. Here we provide the unique identifier for each individual, the species and sex, the date the individual was captured, the estimated birth year and age, and the CDV antibody titer results based upon serum neutralization assays.

We collected diets on Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and brown trout (Salmo trutta) above (Yellowstone cutthroat trout allopatry) and below (Yellowstone cutthroat trout sympatry with brown trout) a natural barrier in Duck Creek, Montana. We used gastric lavage methods to collect diets, and samples were placed in storage containers and taken back to our lab and frozen until sorting. All samples were sorted by Rhithron, Inc. (Missoula, MT) with individuals identified down to the order.

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. Seward, also east of the continental divide. This multi-summit approach to monitoring alpine plant species follows the protocols of the Global Observation Research Initiative in Alpine Environments (GLORIA) that were initiated by the University of Vienna in 2000 and which have been refined and revised since then. GLORIA summit sites...
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. Statistical analysis included five types of response data requested from the North American Bat Monitoring Program database (NABat): automatically identified stationary acoustic calls, manually vetted stationary acoustic calls, automatically identified mobile acoustic calls, manually vetted mobile acoustic calls, and capture...

We developed and validated conventional and quantitative real-time PCR assays for the detection of DNA from the myxozoan parasite Tetracapsuloides bryosalmonae, the causative agent of proliferative kidney disease in fish. Assays were tested on fish tissue and on field-collected water samples to assess diagnostic and environmental DNA capabilities. The specificity, sensitivity, and broad applicability of the present assays surpass previous methods for detecting T. bryosalmonae DNA from fish tissue and water samples.

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. been lacking in the Upper Missouri River Basin due to a lack of extended streamflow records. Here we utilize a new database of naturalized streamflow records for the Upper Missouri and an expanded network of tree-ring records from the region to reconstruct streamflow at 31 gaging locations across the major Mountain Headwaters of the United States’ largest river basin. The database also...

From 2003-2018, USGS researchers and collaborators conducted mark-recapture studies of the boreal toad at the Lost Trail National Wildlife Refuge in northwestern Montana, USA. The datasets included here contain information on individual toad capture history, body size, and disease status. These data were collected annually over the 16-year period at up to 11 breeding sites per year on the refuge. We include datasets for (1) male toad captures over time, (2) female toad captures over time, (3) male disease status (tested - positive or negative, or not tested in a given year), (4) all toad length and weight data over time, and (5) male toad size and body condition over time.
Field estimates of the abundance of 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, among others, were collected at sites.

Real-time PCR results of a round robin evaluation of 5 assays that target dreissenid mussel DNA. Water samples collected from waters with and without dreissenid mussels were analyzed using these five assays in four USGS laboratories. Samples from waters without dreissenid mussels were spiked with known amounts of dreissend DNA.
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.
USGS and NPS biologists used distance sampling to estimate abundance of hoary marmots (Marmota caligata) in North Cascades National Park, Washington, USA during 2007-2008 and 2016-2017. Biologists resurveyed hoary marmots in 2016 and 2017 at 78 point-count stations across 19 sites surveyed by NPS in 2007-2008. Data include marmot detection distances and survey conditions used to estimate abundances at each site in each year. Data also include estimated marmot abundances and covariates used to evaluate effects of weather, snowpack, and vegetative phenology and productivity on marmot abundances. Marmots are classified as adult, subadult, or juvenile for observations in which age was evident.

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, and areas where yearly elk supplemental feeding generally occurs on the National Elk Refuge. We sampled 10 transects in Grand Teton National Park and 10 transects in the National Elk Refuge, each 1,000 meters in length. We collected soil samples every 100 meters along the transect for a total of 10 samples per transect. Terra Core...

The data set contains temporal chloride concentrations (mg/L) and specific conductance (uS/cm) values for 32 wetlands and groundwater monitoring wells as well as the date(s) sampled and the laboratory where the water quality analyses were conducted. The ratio of chloride concentration to specific conductance is referred to as the Contamination Index. In this region, values greater than 0.035 are used to identify water quality samples that are contaminated with co-produced water from energy development.
