This collection includes shell-skeletal remains of Gopherus agassizii from 1980 through 2012 that was collected as part of a monograph covering the desert tortoise populations inside and outside the fenced Desert Tortoise Research Natural Area of California during a period of population decline. The principal objectives of the study were to compare trends in demographic and habitat data inside the protective fence with those outside the fence. Populations and habitat outside the fence were unprotected from recreational vehicle use and sheep grazing. Data for each shell-skeletal remain found on the long-term, 7.77 square kilometers plot, included carcass number, previous number as a live tortoise, date of collection,...

The National Uranium Resource Evaluation (NURE) program was initiated by the Atomic Energy Commission (now the Department of Energy; DOE) in 1973 with a primary goal of identifying uranium resources in the United States. The Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program was one of nine components of NURE. Planned systematic sampling of stream sediments, soils, groundwater, and surface water over the entire United States began in 1975 under the responsibility of four DOE national laboratories: Lawrence Livermore Laboratory (LLL), Los Alamos Scientific Laboratory (LASL), Oak Ridge Gaseous Diffusion Plant (ORGDP), and Savannah River Laboratory (SRL). Each DOE laboratory developed its own sample...

Desert LCC Base Maps and Data describe the physical and cultural geography of the Desert Landscape Conservation Cooperative. These products include the Desert LCC vector boundary available as a shapefile and KML, as well as print-quality graphic design files for thematic maps including Watersheds, Land Cover, Vegetation and a Base Map. The scale of the maps is 1:2,500,000. About the Desert LCC Region: Forty percent of the Desert LCC area lies in the United States and the remaining 60 percent, in Mexico. The total DLCC area is 536,955 square miles or 1,390,713 square kilometers. To explore data per Desert LCC priorities, visit the Conservation Planning Atlas.

This collection primarily consists of type fossils from the USGS Menlo Park Vertebrate Cenozoic Paleontology Collection created and maintained by U.S. Geological Survey (USGS). Data were collected by paleontologist Charles A. Repenning during his forty years of service within the USGS Paleontology And Stratigraphy Branch. This collection contains 516 fossil localities from the western United States. This collection was originally created and maintained by U.S. Geological Survey and as of March 2020 has been transferred to the Smithsonian National Museum of Natural History.
