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.
Analysis of Land Disturbance and Pygmy Rabbit Occupancy Values Associated With Oil and Gas Extraction in Southwestern Wyoming, 2012
Germaine, S.S., Carter, S.K., Ignizio, D.A., and Freeman, A.T., 2017, Analysis of Land Disturbance and Pygmy Rabbit Occupancy Values Associated With Oil and Gas Extraction in Southwestern Wyoming, 2012: U.S. Geological Survey data release, https://doi.org/10.5066/F7BR8QDD. DOI: 10.5066/F7BR8QDD
Long-term video surveillance and automated analyses of hibernating bats in Virginia and Indiana, winters 2011-2014
This data release includes video files and image-processing results used to conduct the analyses of hibernation patterns in groups of bats reported by Hayman et al. (2017), "Long-term video surveillance and automated analyses reveal arousal patterns in groups of hibernating bats.”
This data release consists of sex ratio data from cottonwood trees at random points on the floodplain; tree core and tree ring data; floodplain and riparian cottonwood forest areas as shapefiles (SHP); and edges of water, channel centerline, valley bottom centerline, extent of valley bottom, and estimated bankfull channel data as shapefiles (SHP).
Spatial and temporal dynamics of suspended particle characteristics and composition in Navigation Pool 19 of the Upper Mississippi River
Here we investigated two questions: (1) How do suspended particle characteristics (e.g., size and morphology) vary temporally and spatially? and (2) What environmental variables have the strongest association with particle characteristics? Water sampling was conducted in June, August, and September of 2013 and 2014 in Navigation Pool 19 of the UMR.
Life history attributes data for Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus) in Arizona 2013
The Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus) occurs in the desert and plains grasslands of southeastern Arizona, southwestern New Mexico, and northern Sonora, Mexico. This data was produced as part of the first intensive study of its life history and breeding ecology, providing baseline data and facilitating comparisons with other North American Grasshopper Sparrow...
These data were used to examine the effectiveness of a non-lethal tool (Bioelectrical Impedance Analysis) to estimate the physiological condition of endangered and threatened fishes in the Colorado River Basin. Humpback chub, bonytail, and roundtail Chub were subjected to different feeding trials to elicit a response in physiological condition.
Standardization and Application of an Index of Community Integrity for Waterbirds in the Chesapeake Bay
This data set is comprised of five files related to the modification and scoring of Index of Waterbird Community Integrity (IWCI) scores for all waterbirds of the Chesapeake Bay. One Excel file (A) contains a list of 100+ Chesapeake waterbird species and their species attribute and IWCI scores.
Evaluating upstream passage and timing of approach by adult bigheaded carps at a gated dam on the Illinois River:Data
This dataset describes the results of this study and was used to compare the residency duration of upstream migrants downstream of SRLD between years, tailwater elevation, and water temperature, and how tailwater elevation and water temperature influenced their timing of arrival downstream of Starved Rock Lock and Dam SRLD.
Data from Wilson, T.S., Sleeter, B.M., Sleeter, R. R., Soulard, C.E. 2014, Land use threats and protected areas: a scenario-based landscape level approach, Land, 3 (2): 362-389. Three maps showing land-use conversion potential, forest harvest potential, and conversion threat index are available for the Pacific Northwest, years 2000-2100.
Estimated precipitation data were compiled from 1995-2013 for sites near Palm Springs, CA and at Sugarloaf Mountain in the Tonto National Forest of AZ. We were interested in data for winter (October-March) and summer precipitation (June-September). These two periods are important for desert tortoise ecology since they trigger germination of food plants in the spring and in the summer.
Stream temperature data from Willow-Whitehorse and Little Blitzen watersheds, southeast Oregon, 2011-2015
These tabular, spatial, and code data sets were created in support of a stream temperature monitoring study in the Willow-Whitehorse and Little Blitzen watersheds in southeastern Oregon from 2011-2015.
Reproductive strategy, spawning induction, spawning temperatures and early life history of captive sicklefin chub Macrhybopsis meeki-Data
Macrhybopsis reproduction and propagule traits were studied in the laboratory using two temperature regimes and three hormone treatments and which methods produced the most spawns. Results from this study determined the reproductive biology and early life history of Macrhybopsis spp. and provided insight into their population dynamics in the Missouri River.
