Tabular datasets containing information related to Dall sheep fecal samples collected as part of the Dall sheep response to fire project at Kenai National Wildlife Refuge. The data contain two related tables, one with the bulk of the information related to the samples (location, date collected, etc.) and a second with information on the substrate types that the samples were collected from used to determine which samples may be best suited for laboratory analysis.

This dataset includes a number of datasets collected to assess the potential effects of GPS telemetry collars on free-roaming feral equid species in North America: horses and burros. The behavior dataset (Behavioral_data_collared_uncollared.csv) includes frequency of maintenance behaviors of collared and un-collared horses at Conger Herd Management Area (HMA), and burros at Lake Pleasant and Sinbad Herd Management Areas (HMAs). The dataset also includes data on collar effects to fur and superficial effects observed, showing the count of fur effects (i.e., sweaty neck, indented fur, broken fur) and superficial effects (chafe, wound, or scab) on horses and burros over the time that they wore a collar (Collar_fur_and_superficial_effects_over_time.csv). Data on physical effects of collars (Equid_collar_effects_data_2016_2020.csv) provides each observation of a horse or burro to record any effects seen. Foal survival data (Horse_burro_foal_survival_collared_uncollared_mother.csv) provides survival of foals to 12 months (or to the end of the study) of collared and un-collared horse and burro mothers. There is data on the success of remote drop off and timed release drop off mechanisms (Collar_remote_release_success_data.csv) that provides counts related to when collars were deployed and when they were dropped or attempted to be dropped from the horse or burro. Collar drop success data shows the number of failed and successful attempts to remove a radio collar after a specified number of months of deployment (Collar_drop_success_at_months_deployed.csv).

Measured concentrations of carbon monoxide, carbon dioxide, and voaltile organic compounds from downwind of prescribe fires in tallgrass prairie ecosystems. Data is in *.csv format. This dataset is associated with the following publication: Whitehill, A., I. George, R. Long, K. Baker, and M. Landis. Volatile Organic Compound Emissions from Prescribed Burning in Tallgrass Prairie Ecosystems. ATMOSPHERE. MDPI AG, Basel, SWITZERLAND, 10(8): 464, (2019).

This dataset provides summary statistics of multiple sage-grouse microhabitat characteristics of the Great Basin. These data support the following publication: Coates, P.S., Brussee, B.E., Ricca, M.A., Dudko, J.E., Prochazka, B.G., Espinosa, S.P., Casazza, M.L., and Delehanty, D.J., 2017, Greater sage-grouse (Centrocercus urophasianus) nesting and brood-rearing microhabitat in Nevada and California—Spatial variation in selection and survival patterns: U.S. Geological Survey Open-File Report 2017-1087, 79 p., https://doi.org/10.3133/ofr20171087.

We evaluated nest site selection and nest survival both before and after a fire disturbance occurred. We then combined those surfaces to determine the areas which were most heavily impacted by the fire.

This dataset included the concentration results (in nanograms per liter) for 328 pharmaceutical and pesticide compounds analyzed within the Great Smoky Mountain National Park, Tennessee and North Carolina, in 2019. Two samples were collected (July and September) at 15 locations within the park, and one location at the park boundary. Samples were analyzed at the National Water Quality Laboratory (NWQL) in Denver, Colorado.

Populations of Dall sheep (Ovis dalli) have been declining in the Chugach Range, Alaska since the 1990s. Past research suggests that fire can increase the carrying capacity of habitat for Dall sheep. To learn more specifically how fire affects Dall sheep in the Kenai Mountains, we conducted a habitat use-availability study within and near the 2019 Swan Lake Fire Burn on the Kenai Peninsula, Alaska. This dataset includes vegetation data collected in 2023 as part of this project.

Wildfire events are becoming more frequent and severe on a global scale. Rising temperatures, prolonged drought, and the presence of pyrophytic invasive grasses are contributing to the degradation of native vegetation communities. Within the Great Basin region of the Western United States, increasing wildfire frequency is transforming the ecosystem toward a higher degree of homogeneity, one dominated by invasive annual grasses and declining landscape productivity. Greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) are a species of conservation concern that rely on large tracts of structurally and functionally diverse sagebrush (Artemisia spp.) communities. Using a 12-year (2008-2019) telemetry dataset, we documented immediate impacts of wildfire on demographic rates of a population of sage-grouse that were exposed to two large wildfire events (Virginia Mountains Fire Complex - 2016; Long Valley Fire - 2017) near the border of California and Nevada. Spatiotemporal heterogeneity in demographic rates were accounted for using a Before-After Control-Impact Paired Series (BACIPS) study design.
