Visual encounter and environmental DNA (eDNA) surveys for amphibians in the Western United States Visual encounter and environmental DNA (eDNA) surveys for amphibians in the Western United States
We used visual encounter surveys (VES) and environmental DNA (eDNA) surveys for amphibians in the western united states. Data are results of both VES and eDNA surveys for all amphibian species that occur in the locations surveyed.
Observed reproductive status and estimated den entrance and emergence data for radio-marked females and estimated birth dates of offspring for four grizzly bear populations in North America, 2011-2021 Observed reproductive status and estimated den entrance and emergence data for radio-marked females and estimated birth dates of offspring for four grizzly bear populations in North America, 2011-2021
This data release contains the observed reproductive status and estimated den entrance and emergence data for 114 radio-marked female grizzly bears and the estimated birth dates of offspring for four populations in North America collected from 2011-2021. The studied populations inhabited the Greater Yellowstone Ecosystem, Northern Continental Divide Ecosystem, Selkirk and Cabinet-Yaak...
Environmental DNA surveillance results for Alchesay National Fish Hatchery, 2021-2024 Environmental DNA surveillance results for Alchesay National Fish Hatchery, 2021-2024
Quantitative PCR results for surveillance of New Zealand mudsnail environmental DNA at the U.S. Fish and Wildlife Service Alchesay National Fish Hatchery.
Survival, productivity, and population index data used to estimate demographic rates and population size for two peregrine falcon management populations in North America, 1980-2024 Survival, productivity, and population index data used to estimate demographic rates and population size for two peregrine falcon management populations in North America, 1980-2024
Population level summary data on survival, reproduction, and population size used to estimate demographic rates and population size for two peregrine falcon management populations in North America using integrated population models. The data are provided in a CSV file and in management population (northern and southern) and model scenario (original, extrapolated, updated) specific R...
Arthropod abundance across a fire severity gradient beneath potential cover objects throughout the Jemez Mountains, New Mexico, USA 2023-2024. Arthropod abundance across a fire severity gradient beneath potential cover objects throughout the Jemez Mountains, New Mexico, USA 2023-2024.
Data containing field observations of potential Jemez Mountains salamander (JMS; Plethodon neomexicanus) cover objects and characteristics of underlying soils, concurrent with arthropod data collected from pitfall traps beneath selected cover objects in salamander historic habitat located in the Jemez Mountains, New Mexico from 2023-2024. We sampled potential salamander prey items...
Characterization of three common land-applied wastes: Inorganic, organic, and microbial compositions of biosolid, livestock, and drilling fluid waste, United States, 2021 and 2022 Characterization of three common land-applied wastes: Inorganic, organic, and microbial compositions of biosolid, livestock, and drilling fluid waste, United States, 2021 and 2022
It is common practice for waste byproducts generated from the treatment of municipal waste (biosolids), livestock production (manure), and oil and gas drilling operations (spent drill fluids and cuttings) to be applied to farmland as a cost-effective means of disposal. From June 2021 to January 2022, 34 samples of land-applied waste materials were collected in 14 U.S. states. Samples...
Autonomous and manual environmental DNA detections of Round Goby (Neogobius melanostomus) in the Hudson River (New York) in June 2024 Autonomous and manual environmental DNA detections of Round Goby (Neogobius melanostomus) in the Hudson River (New York) in June 2024
Quantitative PCR results for samples collected from the Hudson River near Troy, New York by autonomous and manual (backpack) samplers
Environmental DNA sample results from Naval Base Ventura County Point Mugu Sea Range, May and June 2025 Environmental DNA sample results from Naval Base Ventura County Point Mugu Sea Range, May and June 2025
We used an environmental DNA (eDNA) autosampler and a backpack manual sampler to collect eDNA samples at Naval Base Ventura County's Point Mugu Sea Range in May and June 2025. Samples were sent to Wilderlab for metabarcoding analysis using their basic panel of five primers to amplify DNA from a variety of taxa, including vertebrates (fish, mammals, reptiles, amphibians, and birds)...
Temporal environmental DNA data collected from waters in Florida, Idaho, Montana and Wisconsin in 2022 Temporal environmental DNA data collected from waters in Florida, Idaho, Montana and Wisconsin in 2022
This dataset contains quantitative results of environmental DNA water samples from a diverse set of aquatic habitats, including small creeks in Idaho and Montana, a large river in Wisconsin, and an experimental pond in Florida. The frequency of daily sampling was randomly assigned, without duplication, each week to one of four levels: one survey event per day, two survey events per day...
Mountain goats (Oreamnos americanus) in Glacier National Park, Montana, USA, and Waterton Lakes National Park, Alberta, Canada, 2008-2023 Mountain goats (Oreamnos americanus) in Glacier National Park, Montana, USA, and Waterton Lakes National Park, Alberta, Canada, 2008-2023
Dataset includes a) counts of mountain goats for multiple surveys across 37 sites inside Glacier National Park 2008-2019, along with biotic and abiotic conditions used in analysis of trend including snow, precipitation, temperature, landcover and habituation; b) predicted numbers of goats using each survey area; and c) microsatellite genotypes for goat pellet samples collected 2019-2023...
Environmental DNA sample results from Santa Cruz Island, California, May 2025 Environmental DNA sample results from Santa Cruz Island, California, May 2025
We used Wilderlab eDNA kits to collect eDNA samples in a creek colloquially known as Cañada del Puerto Creek (Hydrologic Unit Code 12 number 180600140201) on Santa Cruz Island, California, in May 2025. Samples were sent to Wilderlab for metabarcoding analysis using their comprehensive panel of assays to amplify DNA from a variety of taxa, including vertebrates (fish, mammals, reptiles...
