nas.er.usgs.gov — This site has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The data is made available for use by biologists, interagency More...

www.fort.usgs.gov — This report provides a preliminary review of adaptation options for climate-sensitive ecosystems and resources in the United States. The term "adaptation" in this document refers to adjustments in human social systems (e.g., management) in response to climate stimuli and their effects. Since management always occurs in the context of desired More...

wfrc.usgs.gov — The whole study, conducted at Fort Benning, Georgia, partially funded through the US Army, involves testing of water and soil quality, physical and biotic indicators of stress at both the population and community level. Anthropogenic stress in the present study comes from disturbance by vehicles, particularly tanks used in army training, and from More...

fl.biology.usgs.gov — The connection between fish habitat utilization, prey use, and fish movement patterns is not known in relation to available invertebrate prey resources in off-reef sites. Developing a better understanding of the habitat use, diet, and resource needs of benthic communities and their interactions with mobile fish and invertebrates is an important 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...

fl.biology.usgs.gov — Invasive nonindigenous species are important because they threaten native communities, alter habitats, and can have significant economic impacts. In aquatic environments, invasive species can be especially noxious because native species have few options for escaping direct interactions such as predation and competition for habitat and food. This More...
