Mariana swiftlet (Aerodramus bartschi) survey data from O'ahu, Hawai'i, 2005-2010
The data set contains Mariana swiftlet (Aerodramus bartschi) population survey data that were collected via evening arrival surveys on the island of O'ahu, Hawaiian Islands. Data were collected at a roosting/nesting tunnel used by Mariana swiftlets in North Halawa Valley.
Forest Management and Cervid Herbivory Data from Western Oregon, USA, 2012 (Seedling Data)
Land management practices often directly alter vegetation structure and composition, but the degree to which ecological processes such as herbivory interact with management to influence biodiversity is less well understood. We hypothesized that intensive forest management and large herbivores have compounding effects on early-seral plant communities and plantation establishment (i.e., tree
Oregon Spotted Frog (Rana pretiosa) Monitoring at Jack Creek 2015-2018
This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2018 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort at Jack Creek, Klamath County, Oregon. Data consist of spotted frog counts (handled by surveyors) aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the
Western US Ruggedness Raw Values
"Vector Ruggedness Measure (VRM) measures terrain ruggedness as the variation in three-dimensional orientation of grid cells within a neighborhood. Vector analysis is used to calculate the dispersion of vectors normal (orthogonal) to grid cells within the specified neighborhood. This method effectively captures variability in slope and aspect into a single measure. Ruggedness values in
Oregon Spotted Frog (Rana pretiosa) Monitoring at Jack Creek 2015-2017
This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2017 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort at Jack Creek, Klamath County, Oregon. Data consist of spotted frog counts (handled by surveyors) aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the
Genetic data from Red-cockaded woodpeckers (Dryobates borealis) used to assess changes in population genetic differentiation and diversity over the past century throughout the southeastern United States.
These data include nuclear microsatellite data and mitochondrial DNA sequences (mtDNA) for specimens of Red-cockaded woodpeckers collected from three time points: 1881-1969 (mtDNA only), 1992-1994, and 2010-2014. Additional information regarding individual identifiers, population assignment, regional assignment, and eco-regional assignment are included as are longitude/latit
Forest management and cervid herbivory data from Western Oregon, USA, 2012 (Community Data)
Land management practices often directly alter vegetation structure and composition, but the degree to which ecological processes such as herbivory interact with management to influence biodiversity is less well understood. We hypothesized that intensive forest management and large herbivores have compounding effects on early-seral plant communities and plantation establishment (i.e., tree
Probability of Streamflow Permanence (PROSPER) Continuous Parameter Grids (CPGs)
The U.S. Geological Survey (USGS) has developed the PRObability of Streamflow PERmanence (PROSPER) model, a GIS raster-based empirical model that provides streamflow permanence probabilities (probabilistic predictions) of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides annual

Habitat use, diet, movement, and vegetation use by western gray squirrels (Sciurus griseus) in the North Cascades Range, USA, 2008-2011
Data are contained in a comma-separated spreadsheet files (.csv) that describe vegetation characteristics of high- and low-use areas, nest tree sites, and individual nest trees used by western gray squirrels in the North Cascades as determined through live-trapping and radiotelemetry at two study sites: Stehekin, and the southern Methow Valley (Squaw Creek drainage), Washington.
