www.fort.usgs.gov — With the exception of Aspen, coniferous species dominate the forests of the Rocky Mountains (Populus tremuloides Michx.; Peet, 2000). The establishment of new aspen stands in the central Rocky Mountains generally follows major disturbances, particularly forest fires, with new stems sprouting from surviving root systems and with rare establishment More...

www.werc.usgs.gov — The Alameda whipsnake (Masticophis lateralis euryxanthus) is both a federally and state listed endangered species limited to scrub and chaparral habitat within Contra Costa and Alameda Counties, CA. Loss and fragmentation of habitat due to agricultural and urban development over the last 100 years are cited as the main causes of its decline. Based More...

wfrc.usgs.gov — Viral infections are common causes of disease outbreaks and mortalities in both wild and captive fish populations. Due to the long history of virus outbreaks there is a substantial body of knowledge about viruses within the field of fish pathology. This project involves research and development studies which create, modify and apply modern More...

www.lsc.usgs.gov — The primary goal of this study is to clarify how riparian zone and land use affect T. tubifex population density, lineage and myxosporidian parasite density and/or the ability of resident worms to become infected with M. cerebralis spores and to release infective spores. Preliminary results suggest that a deciduous riparian zone reduces the More...
