Environmental DNA qPCR concentration results and environmental covariates from a Montana headwater stream sampled in 2023 Environmental DNA qPCR concentration results and environmental covariates from a Montana headwater stream sampled in 2023
Environmental DNA quantitative results at the PCR technical replicate level for the target species Arctic Grayling and covariate information associated with these eDNA samples.
Environmental DNA qPCR detection results and covariates from Idaho, Missouri, Montana, and New York rivers sampled in 2023 Environmental DNA qPCR detection results and covariates from Idaho, Missouri, Montana, and New York rivers sampled in 2023
This dataset contains quantitative results from, and covariate attributes of, environmental DNA water samples collected across multiple rivers in 2023. Samples were analyzed for eDNA of round goby in the Hudson River (NY), westslope cutthroat trout (Oncorhynchus clarkii lewisi) in Cherry Creek (MT), lake trout (Salvelinus namaycush) and Spectaclecase mussels (Cumberlandia monodonta) in...
Winter Tick Host Competency Data from Elk and Moose in the Southern Greater Yellowstone Ecosystem 2020-2023 Winter Tick Host Competency Data from Elk and Moose in the Southern Greater Yellowstone Ecosystem 2020-2023
Three tabular datasets providing tick counts from various transects and reproduction sites around Jackson, Wyoming. One table with data from total number of winter ticks collected running a transect along either an elk or moose hide, another table with winter tick counts collected and counted in a 250 m drag transect, and then the last table is the count of larvae that come from one fed...
Mid-Holocene-to-present Modeled (ca., 7,000 to 100 cal. BP) and Reconstructed (ca., 5,900 to 5,436 cal. BP) Temperature for the High-Elevations of the Greater Yellowstone Ecosystem: Derived from a Transient Climate Model and Whitebark Pine Tree-rings Mid-Holocene-to-present Modeled (ca., 7,000 to 100 cal. BP) and Reconstructed (ca., 5,900 to 5,436 cal. BP) Temperature for the High-Elevations of the Greater Yellowstone Ecosystem: Derived from a Transient Climate Model and Whitebark Pine Tree-rings
In the Rocky Mountains of the Greater Yellowstone Ecosystem (United States), recent melting at a high-elevation (3,091 m asl) ice patch exposed a mature stand of whitebark pine (Pinus albicaulis) trees located ~180 m above modern treeline dating to the mid-Holocene (c. 5,900-5,436 cal y BP +- 51 y). From this subfossil wood record, we contextualize the recent magnitude of warming...
Assessing adaptive management to reduce ungulate aggregations: A case study involving the supplemental feeding of elk. Assessing adaptive management to reduce ungulate aggregations: A case study involving the supplemental feeding of elk.
This data release contains summarized elk aggregation metrics generated from Global Positioning System (GPS) collar locations of elk on the National Elk Refuge in Jackson, Wyoming. Aggregation metrics include annual kernel density estimates of the area used by elk on the National Elk Refuge, daily measures of inter-elk distances, daily pairwise proximity, and daily mean proximity and...
Tree ring dataset for a regional avalanche chronology in Colorado 1319-2022 Tree ring dataset for a regional avalanche chronology in Colorado 1319-2022
This dataset includes processed tree ring data from avalanche paths throughout Colorado, USA. The data were processed in three distinct phases that resulted in this dataset: collection, processing, and avalanche signal analysis. This dataset consists of samples from 1188 cross-sections and increment cores from 1023 individual trees within 24 avalanche paths across the region. From these...
Working Dog Tick Transect results and cost comparisons in Jackson Hole, WY from Oct - Nov 2021 Working Dog Tick Transect results and cost comparisons in Jackson Hole, WY from Oct - Nov 2021
A tabular dataset providing tick survey results around the Jackson Wyoming area between the dates of Oct 25, 2021, and Nov 6, 2021. The data compares a dog surveyor to a human surveyor in both transect and survey plots, recording detection events, total number of tick larvae found, and how long the survey took, and the cost of the survey. A second tabular dataset outlining the associated...
Metabarcoding of environmental DNA samples collected below Jackson Lake Dam (Wyoming) and Palisades Reservoir (Idaho) in 2021-2022 (ver. 2.0, November 2024) Metabarcoding of environmental DNA samples collected below Jackson Lake Dam (Wyoming) and Palisades Reservoir (Idaho) in 2021-2022 (ver. 2.0, November 2024)
These metadata contain links to the original sequences on GenBank. These data show the final OTU and metadata tables for each environmental sample collected. Additionally, we included OTU tables resulting from bioinformatic decontamination steps (using microDecon) in R.
Desert bighorn sheep (Ovis canadensis nelsoni) datasets from Grand Canyon National Park, 2010-2016 Desert bighorn sheep (Ovis canadensis nelsoni) datasets from Grand Canyon National Park, 2010-2016
Tabular and raster data containing spatial capture recapture records for male and female bighorn sheep (Ovis canadensis nelsoni) in Grand Canyon National Park and surrounding landscape collected from 2010 to 2018 and associated tabular data files required for analysis of data with spatial capture connectivity models and raster data describing the ouput from SCR models. Associated tables...
Bumble bees and flowering plants in Glacier National Park 2023 Bumble bees and flowering plants in Glacier National Park 2023
USGS personnel surveyed bumble bees and flowering plants in and around Glacier National Park during the summer of 2023. These data include 1) a .csv file of all bumble bee - plant interactions observed across surveys and 2) all flowering plants observed in bloom across all surveys.
