Predicted Risk of Negative Human-Black Bear Interactions in Maryland under Neutral and Drought Conditions Predicted Risk of Negative Human-Black Bear Interactions in Maryland under Neutral and Drought Conditions
Reports of negative interactions between humans and bears in Maryland have increased steadily since the 1990s, requiring substantial investments of time and resources for their management. While managers typically possess a strong understanding of the spatial distribution of current and historical interactions, they lack the quantitative tools necessary to predict where future...
Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2025 Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2025
We provide fractional cover estimates for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from mid-April to late June 2025. The cover estimates reflect actual conditions of the previous week and are released in an expedited manner, within 7-13 days of the latest satellite observation used for that weekly prediction. Each weekly release contains...

Global gridded dataset of terrestrial biological nitrogen fixation across natural and agricultural biomes Global gridded dataset of terrestrial biological nitrogen fixation across natural and agricultural biomes
This dataset includes global rasters of terrestrial biological nitrogen fixation (BNF) rates (in kg N/ha/y) for each major N-fixing niche in natural biomes (trees, shrubs, herbs, soil, litter, dead wood, ground mosses, biocrusts, and epiphytic lichens) and agricultural biomes (legume crops, forage legumes, and rice). It also includes total natural terrestrial, total agricultural, and...
A global dataset of terrestrial biological nitrogen fixation A global dataset of terrestrial biological nitrogen fixation
This dataset includes field measurements of biological nitrogen fixation (BNF) in all major N-fixing niches across natural terrestrial biomes globally. The dataset comprises 32 variables including site location, biome type, N-fixing niche, sampling year, quantification method, BNF rate (in kg N/ha/y), the percentage of nitrogen derived from the atmosphere, N-fixer or N-fixing substrate...
California condor and black vulture Highly Pathogenic Avian Influenza vaccine trial California condor and black vulture Highly Pathogenic Avian Influenza vaccine trial
In 2023, critically endangered California condors experienced an outbreak of highly pathogenic avian influenza (HPAI). We evaluated safety, immunogenicity, vaccination strategies, and correlates of antibody response of a conditionally licensed influenza vaccine for poultry in black vultures and then California condors. These data represent the correlates of antibody response, including
Comparison of environmental DNA sampling protocols for detection of stream fishes in the Pacific Northwest, 2019 (ver. 2.0, November 2025) Comparison of environmental DNA sampling protocols for detection of stream fishes in the Pacific Northwest, 2019 (ver. 2.0, November 2025)
This dataset contains environmental DNA (eDNA) data (field, extraction, and qPCR) for rainbow trout sampling efforts conducted in the Pacific Northwest in 2019. Samples were collected using three eDNA sampling methods. Also included are qPCR data for extraction negatives, no-template controls (NTC), and standard dilutions of rainbow trout gBlock. NTC and gBlock qPCR data were used to...
Population viability assessment of native fish species in the Pacific Northwest accounting for instream conditions of water temperature and streamflow permanence Population viability assessment of native fish species in the Pacific Northwest accounting for instream conditions of water temperature and streamflow permanence
This data release contains geospatial representations of population viability analysis (PVA) of 23 species of Pacific Northwest non-salmonid fishes. The analysis evaluated long term species persistence (~100 years) based on species distribution models that combined 1) modeled climate, 2) instream conditions, and 3) presence/absence fish data based on species needs and current climate...
Species distribution models and model performance evaluations of twenty-four fishes native to Pacific Northwest US Species distribution models and model performance evaluations of twenty-four fishes native to Pacific Northwest US
This data release provides spatial data for species distribution models developed for 24 stream fishes native to the Pacific Northwest, USA and associated model evaluation metrics used to determine the best supported model. These models support a larger analysis for understanding native stream fish vulnerability in the region, specifically population viability analyses built to determine...
Pesticide Concentrations Measured During In-Situ Active Water Sampler Testing in Solano County, California, 2023 Pesticide Concentrations Measured During In-Situ Active Water Sampler Testing in Solano County, California, 2023
A novel U.S. Geological Survey-developed active water sampler was deployed at Ulatis Creek in Solano County, California for 24 hours from November 15, 2023 to November 16, 2023. Discrete surface water samples were collected at the start and end points of the active water sampler deployment interval for comparison to the active water sampler. Samples from the active water sampler and the...
Pesticide concentrations in multiple stream matrices collected near Mead, Nebraska, 2022 Pesticide concentrations in multiple stream matrices collected near Mead, Nebraska, 2022
The AltEn bioenergy plant (Mead, Nebraska, USA) previously (2015 to 2021) generated ethanol from almost 100% unused/expired treated corn seeds. This use of treated corn seeds as a feedstock for ethanol production resulted in accumulation of large amounts of contaminated wastewater and solid residue at the plant, a portion of which was applied to surrounding farmland. To better understand...
LUCAS model estimates of forest ecosystem carbon dynamics in California under different initial conditions scenarios LUCAS model estimates of forest ecosystem carbon dynamics in California under different initial conditions scenarios
This dataset provides tabular data output from a series of modeling simulations for forest ecosystems of the U.S. state of California under different initial conditions scenarios. We used the LUCAS state and transition simulation model with carbon stocks and fluxes based on the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3) to simulate changes in forest ecosystem carbon...
