Coastwide Reference Monitoring System (CRMS) 2021 land-water classification data, Eastern Louisiana

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitor

Antibiotic and Antibiotic Resistance Signatures in Iowa Streams, 2019

Chemical and microbiological results, quality assurance and quality control, site location, and method information for surface water, bed sediment, and wastewater effluent collected from 34 stream locations across Iowa (United States). Environmental samples were analyzed for a suite of 29 antibiotics, plated on selective media for 15 types of bacteria growth, and DNA was extracted from culture gro

Data on flea control using lufenuron and nitenpyram baits with black-tailed prairie dogs, South Dakota, 2021

We collected fleas from a colony of black-tailed prairie dogs on Buffalo Gap National Grassland, South Dakota, 2021. We collected flea data by combing prairie dogs and swabbing their burrows for fleas. Regarding combing, we anesthetized trapped prairie dogs (and their fleas) with isoflurane in induction chambers for processing. We combed each individual with a fine-tooth comb for 30 seconds to rem

Mercury concentrations in amphibian tissues across the United States, 2016-2021

Comma-separated values (.csv) file containing data related to amphibian sampling across the United States between 2016 and 2021. Data files contain mercury concentrations in amphibian and dragonfly tissues, mercury concentrations in sediment, as well as amphibian morphometrics, and habitat and climate characteristics where the samples were collected.

Mercury Concentrations, Diet, and Gut Microbiota Diversity of Southern Beaufort Sea Polar Bears, 2008-2019

This dataset is two tables with data collected and derived from polar bears sampled in Alaska's southern Beaufort Sea during 2008-2019. Collected data includes demographic and morphometric information and derived data includes mercury concentrations in hair samples. Ancillary data includes gut microbiome abundances, diversity indices, calculated body condition, and the proportions of prey species

Panarctic permafrost microbial community and edaphic data collected from 2010-2020

The datasets contained herein include permafrost microbial community taxanomic and functional information using metagenomics from 133 samples across the panarctic. Datasets also include soil edaphic and location data.

Grain-size data for sediment samples collected in Whiskeytown Lake, northern California, in 2018 and 2019

This data release supersedes version 1.0, published in July 2021 at https://doi.org/10.5066/P9BHOPEP. Versioning details are documented in the accompanying Whiskeytown_VersionHistory.txt file The Carr Fire ignited in northern California in July 2018, and ultimately burned almost 300,000 acres (approximately half on federal lands), resulting in a federal major-disaster declaration (DR-4382). Approx

Sediment grain-size data from the Klamath estuary, California

This data release supersedes version 1.0, published in November 2021 at https://doi.org/10.5066/P9CAZIHJ. Versioning details are documented in the accompanying Klamath_Grainsize_VersionHistory.txt file.  This data release includes grain-size measurements of sediment samples collected from the substrate surface and uppermost 10 cm of sediment deposits in the Klamath estuary, northern California.

North American Bat Monitoring Program (NABat) Integrated Summer Species Distribution Model: Predicted Tricolored Bat Occupancy Probabilities

These data contain the results from the North American Bat Monitoring Program's (NABat) integrated species distribution model (iSDM) for tricolored bats (Perimyotis subflavus). The provided tabular data include predictions (with uncertainty) for tricolored bat occupancy probabilities (i.e., probability of presence) based on data from the entire summer season (May 1–Aug 31), averaged from 2017-2022

North American Bat Monitoring Program (NABat) Bayesian Hierarchical Model for Winter Abundance: Predicted Population Estimates (2022 and 2023)

The dataset is comprised of historical observations and predictions of winter colony counts at known sites for three bat species (little brown bat, Myotis lucifugus; tricolored bat, Perimyotis subflavus; and big brown bat, Eptesicus fuscus). The dataset consists of two separate but related data files in tabular format (comma-separated values [.csv]). Each data set consists of predicted winter coun

Characteristics, presence of erosional features, and cover of vegetation and bare ground on fields formerly enrolled in grassland, wetland, and wildlife practices of the Conservation Reserve Program in the central and western United States from 2017 to 20

Data included in this data set are from edge-of-field surveys that recorded the presence of erosional features, cover of vegetation and bare ground, and management activities (e.g., haying) on 1092 fields that had expired from three types of conservation practices (grassland, wetland, and wildlife) in the Conservation Reserve Program. Field sampling data were recorded across six US Department of A

Data on separated and dead foals from Conger and Frisco Herd Management Areas, Utah, USA, between 2017 and 2020

We studied factors affecting separation of feral horse foals from their mothers and foal mortality, including variables such as group changes by the mother and behavior of the foal. We include data on feral horse foals that died or were separated, and their siblings. We conducted this study between 2017 and 2020 at two Herd Management Areas (HMAs) in western Utah, USA: Conger and Frisco. We conduc
