This website and database hosts records of fossil pollen, charcoal, and mammal assemblages, as well as plant macrofossils, largely from North America, but also globally, throughout the Pleiocene-Quaternary (and Anthropocene). Also included are chronological controls that allow the use of the records through time from the last 5 million years...MORE
This report documents an... "LCTA database update that provides selected ecological attributes (particularly for the nesting season) for 676 bird species occurring within the continental United States. This database upgrade provides land managers the capability to: (1) generate ecological guild-based summaries with no additional fieldwork, (2) identify specific groups of...MORE
The USGS Gap Analysis Program (GAP) is delineating species range and predicted distribution maps for more than 2,000 species that occur within the continental US as well as Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands (we will make these maps and datasets available as they are completed). Our...MORE
