Data and Tools
Biology and Ecosystems Datasets
Mapping, Remote Sensing, and Geospatial Data
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.
Survival of larval Boreal Chorus Frogs (Pseudacris maculata) reared on sediments from brine-contaminated wetlands and a control source.
California spotted owl fledgling counts, climate, and landscape habitat at territories on the Lassen National Forest, CA 1991-2010
This is a comma separated values (CSV) file used to conduct the logistic quantile regression analyses in R provided by Cade et al. (2017). The data set consists of records of California spotted owl fledgling counts on 88 territories on the Lassen National Forest, CA from 1991-2010. Climatic condition data were obtained from PRISM and landscape habitat data were obtained from LANDFIRE.
The National Water Census Data Portal contains national estimates of water budget components for local watersheds, water withdrawal data for counties, tools to calculate statistics of daily streamflow records, modeled daily streamflow at ungaged stations, and access to records of aquatic biology observations.
Roadside Survey Data from southeastern Arizona and New Mexico for Grasshopper Sparrow and other grassland Birds 2003 to 2005
These data include descriptions of all roadside segments surveyed, including GPS waypoints and verbal descriptions for each point (every half mile), survey data collected on roadside surveys in 2003-2005 in the months of July and August, along roads within the known breeding range of the Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus).
Chemical cues which include amino acids mediate species-specific feeding behavior in invasive filter-feeding bigheaded carps-Data
Data generated from a study in which five experiments were conducted that tested whether and how dissolved chemicals might assist food recognition in two filter-feeding fishes, the silver (Hypophthalmichthys molitrix) and the bighead carp (H. nobilis).
DATA RELEASE - Water Classification of The Colorado River Corridor, Grand Canyon, Arizona, 2013—Data
These data are classified maps of water in the Colorado River at a discharge of approximately 227 meters squared/second in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013.
DATA RELEASE - Riparian Vegetation Classification of the Colorado River Corridor, Grand Canyon, Arizona, 2013—Data
These data are classification maps of total riparian vegetation along the Colorado River in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona, and are derived from interpretation of multispectral high resolution airborne imagery acquired in May 2013.
Atypical Feeding Behavior of Long-tailed Ducks in the Wake of a Commercial Fishing Boat while Clamming
Data represents analyses of gizzard and gullet (esophagus and proventriculus) of nine ducks using traditional techniques
Occurrence of plague epizootics in colonies of black-tailed prairie dogs, Pawnee National Grassland, Colorado, 1982-2005
Data on the occurrence of plague epizootics in colonies of black-tailed prairie dogs, Pawnee National Grassland, Colorado 1982-2005. Data are derived from annual prairie dog surveys conducted by staff of the Pawnee National Grassland, U.S. Forest Service.
The Southwest Exotic Plant Mapping Program (SWEMP) is a collaborative effort to compile and distribute regional data on the occurrence of non-native invasive plants in the southwestern U.S. The database represents the known sites of non-native invasive plant infestations within AZ and NM, and adjacent portions of CA, CO, NV and UT. These data were collected from 1911to 2006.
