Characteristics of Sites Sampled for eDNA of Amphibians in Mendocino County, California, 2016 Characteristics of Sites Sampled for eDNA of Amphibians in Mendocino County, California, 2016
Stream-obligate amphibians are important indicators of ecosystem health in the Pacific Northwest, but distributional information to improve forest management is lacking in many regions. We analyzed archived DNA extracted from water samples in 60 pools within streams in private timberlands in Mendocino County, California, for 3 California Species of Special Concern - Coastal Tailed Frogs...
Pacific Northwest tidal marsh plant biomass from a 2017 greenhouse experiment with flooding and salinity manipulations Pacific Northwest tidal marsh plant biomass from a 2017 greenhouse experiment with flooding and salinity manipulations
The sensitivity of tidal marshes to environmental changes that result from sea-level rise or drought conditions is uncertain. We used a controlled greenhouse experiment and factorial flooding x salinity treatments to explore the differential responses of three tidal marsh plant species. Each species exhibited unique responses, with negative responses to increased salinity and longer...
Comparisons of Gambel's quail survey methods conducted in 2016 within the Mohave Desert of California with results and summaries Comparisons of Gambel's quail survey methods conducted in 2016 within the Mohave Desert of California with results and summaries
Data includes results collected in the Mohave Desert during 2016 using three survey methods (acoustic recording units, camera traps, and call-count surveys) to detect gamebirds, primarily Gambel's quail (Callipepla gambelii) but also including records of mourning dove (Zenaida macroura), Eurasian collared-dove (Streptopelia decaocto), and chukar (Alectoris chukar). ARU data includes the...
Coastal California Gnatcatcher Habitat Suitability Model for Southern California (2015) Coastal California Gnatcatcher Habitat Suitability Model for Southern California (2015)
This habitat model was developed to delineate a sampling frame for regional monitoring of coastal California gnatcatchers (Polioptila californica californica) to determine: 1) percent area occupied (PAO) in high and very high suitability habitat across conserved lands and participating military lands in the U.S. range in southern California; 2) changes in PAO over time; and 3) extinction...
USGS National and Global Oil and Gas Assessment Project -- Horn River Basin, Cordova Embayment, and Liard Basin, Canada, Assessment Unit Boundaries and Assessment Input Forms USGS National and Global Oil and Gas Assessment Project -- Horn River Basin, Cordova Embayment, and Liard Basin, Canada, Assessment Unit Boundaries and Assessment Input Forms
This data release contains the boundaries of assessment units for the assessment of undiscovered oil and gas resources in the Horn River Basin, Cordova Embayment and Liard Basin in Alberta Basin Province, Canada. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined...
Long-term gas and heat emissions measurements, Norris Geyser Basin, Yellowstone National Park Long-term gas and heat emissions measurements, Norris Geyser Basin, Yellowstone National Park
We installed an eddy covariance station on July 10, 2018 at Bison Flat, an acid-sulfate, vapor-dominated area (0.04-km2) in Norris Geyser Basin, Yellowstone National Park, WY to monitor variations in hydrothermal gas and heat emissions. Since then, this station has measured CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, and wind speed and direction on a half...
