Digital Archive of the R.S. Thompson western United States Packrat Midden Collection This data release provides a digital inventory of the Robert S. Thompson packrat midden collection consisting of 1,740 midden samples and subsamples primarily collected in the Great Basin region of Nevada, as well as in Arizona, California, Colorado, Oklahoma, Utah, and Washington, USA, by Robert S. Thompson (USGS scientist emeritus) and others between 1977 and 2006. Middens are waste piles composed of the urine and feces of packrats (Neotoma spp.) also containing plant materials, bones, and insects. Radiocarbon dating of middens indicates they can be preserved for as long as 50,000 years, and their fossil plant assemblages document changes in plant community composition through time, providing important records...

They are being provided to meet the need for timely best science. The data have not received final approval by the U.S. Geological Survey (USGS) and are provided on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from the authorized or unauthorized use of the data. The Interagency Grizzly Bear Study Team (IGBST) evaluates mortalities for population segments within the DMA by deriving estimates of total mortality for independent-age (2 years or older) females and independent-age males, including estimates of unknown/unreported mortalities based on Cherry et al. (2002). We then determine... Categories: Data, Data Release - In Progress; Tags: Greater Yellowstone Ecosystem, Greater Yellowstone Ecosystem, Idaho, Montana, United States, All tags...
