Water quality data from the Goose Lake Study Site Eastern Montana 1989-2018

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 u

Plant cover data sets for implementing beta distribution based models

The data were collected every year from 2011 until 2017 at the Clarno unit of the John Day Fossil Beds National Monument. The areal plots were placed following a random selection of locations based on the GRTS algorithm. There was a fire documented in 2011 and interest is in assessing whether there is evidence of cheatgrass distribution or abundance increasing in the monument post-fire.

Paleohydrologic reconstructions of water-year streamflow for 31 stream gaging sites in the Missouri River Basin with complete data for 1685 through 1977

Tree-ring reconstructions of water-year (Oct 1 through Sep 30th) flow for 31 gaging sites in Missouri River basin, with complete data for 1685 through 1977 (n = 293 water years). The complete 105 tree-ring reconstructions of streamflow used in the Nature Scientific Reports paper were obtained from various sources; 74 flow reconstructions were obtained from the web resource, TreeFlow (http://www.tr

Environmental DNA results for large and small volume water samples in mesocosm experiments at Creston Fish Hatchery and field surveys in the Flathead River Basin, MT in 2016

Quantitative PCR data from mesocosm experiments and field evaluations comparing coarse filter-large water volume environmental DNA samples vs. fine filter-small water volume environmental DNA samples for detection and quantification of rainbow trout (Oncorhynchus mykiss) and bull trout (Salvelinus confluentus) DNA. Mesocosm experiments took place at the US Fish & Wildlife Service's Creston Fish Ha

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 model framewor

Yellowstone Cutthroat Trout and Brown Trout capture-recapture and diet data from Duck Creek, MT in summer and fall (2013-2016)

We collected lengths and weights and diets of 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.

Annual winter elk movements in the Greater Yellowstone Ecosystem 2001-2015

521 unique elk with GPS collars were tracked using telemetry from 2001 to 2015 in the Greater Yellowstone Ecosystem to determine winter-to-winter annual dispersal distance of each individual. All elk were identified and located using telemetry during the months of January and February for two successive years. An individual elk was included at most three times in the data and each year was conside

Environmental DNA detection data of Northern pike (Esox lucius) using a portable, field-based platform and a lab-based platform

We used a portable, field-based approach (hereafter referred to as Biomeme approach) and a standard lab-based approach (hereafter referred to as lab approach) to analyze field water samples for northern pike ((Esox lucius) DNA. The Biomeme approach included a field-capable DNA extraction, a shelf-stable assay, and a portable real-time PCR thermocycler. The lab approach included lab-based DNA extra

Bear capture recapture sampling in Glacier National Park, Montana, 2004

Text files containing detection events from genetic sampling sites associated with the unique identifier of American black bears in Glacier National Park, Montana, USA, 2004. Data is formatted for spatial capture recapture data analysis.

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 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)

Counts of American Pikas and Hoary Marmots in North Cascades National Park 2016-2017

USGS scientists counted American pikas (Ochotona princeps) and hoary marmots (Marmota caligata) in North Cascades National Park, Washington, USA during 2016. Hoary marmots were resurveyed in 2017, primarily by the National Park Service. Pika and marmot counts were collected to assess effects of weather and snowpack dynamics on these species. Counts are measures of relative abundance that may be us

Elk GPS collar data from National Elk Refuge (2006-2015)

17 adult female elk were captured on or around the National Elk Refuge and monitored with GPS collars from 2006 to 2015. Each of these elk were monitored for 1 to 2 years and migrated from the National Elk Refuge to Yellowstone National Park during the spring. Here we provide the unique identifier for each individual elk, the date/time stamp of each GPS location, the GPS location of the elk in UTM
