Data

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...

This dataset provides time series for the ungaged watershed inflows and associated inflow points for the Lower Salinas Valley Hydrologic Models (SVHM), including the Salinas Valley Integrated Hydrologic Model (SVIHM) and the Salinas Valley Operational Model (SVOM). Monthly outflows from watersheds that do not have gages that surround the Salinas River Valley are used in the Lower Salinas...

The U.S. Geological Survey conducted sampling across the United States between 2017 and 2022 to assess the effects of methylmercury bioaccumulation and amphibian chytrid fungus (Batrachochytrium dendrobatidis; Bd) on the survival of amphibian species. This dataset includes detections and non-detections of Bd (obtained from DNA extracted from skin swabs) and whole-body methylmercury...

Data from a Nevada telemetry study extending 1997-2006 research on historical mercury contamination on snowy egrets (Egretta thula) up to ~ 20 days of age.

Data includes functional group cover of exotic annual grasses and deep rooted perennial grasses within the first five years after the 2015 Soda wildfire across different post-fire restoration treatments. Additional landscape and restoration treatment covariates hypothesized to influence post-fire invasive annual grass and perennial grass cover are included.

This dataset contains environmental DNA (eDNA) and visual encounter survey (VES) data collected between 2019 and 2022 in Colorado canyonlands. eDNA data (field, extraction, and qPCR) is for three target species: American bullfrog, northern leopard frog, and Great Basin spadefoot. VES data is for six target species: American bullfrog, northern leopard frog, Great Basin spadefoot, red...

Decision support tools play a critical role in assisting coastal decision-makers in managing coastal systems; yet there are challenges to developing tools that align with the functional needs of end-users. By combining usability testing and contextual inquiry methods, we put forth a hybrid approach for collecting user feedback within the context of federal government research. This...

IMPORTANT NOTE: This dataset includes spatial locations where streamflow permanence observations (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123 mobile data collection application. Additional information to describe the field conditions are included as part of the survey. Field observations in the...

Soil data includes carbon (total, organic, mineral-associated, particulate-organic) and texture. Bulk density data includes bulk density values used to calculate carbon stocks. Plant data includes microsite coverage percents and sagebrush demographics. Data is from uninvaded and cheatgrass invaded points near Grand Junction, Colorado and Rock Springs, Wyoming in October and November 2023...

Comma-separated values (.csv) file containing data related to mercury in biota collected from the Hells Canyon Reservoir Complex on the Snake River, Idaho and Oregon.

Wind energy is important for achieving net-zero greenhouse gas emissions but also contributes to global bat mortality. Current strategies to minimize bat mortality due to collision with wind-turbine blades fall broadly into two categories: curtailment (limiting turbine operation during high-risk periods) and deterrence (discouraging bat activity near turbines). Recently, there has been...

This dataset provides the plot-level data of the relative cover of ten different plant associations derived from a structural topic model and resistance and resilience metrics for predicting their abundances. Data comes from four different fires across the Great Basin: the 2007 Murphy Fire, 2012 Rush Fire, 2012 Holloway Fire, and the 2015 Soda Fire. Additional data utilized in the cross...
