Report on a community of microscopic organisms, Archaea, found deep in an Idaho hot spring living on hydrogen and carbon dioxide that could possibly exist on other planets. Includes links to related studies, investigators, and microbiology.
These lightless and nutrient-poor natural systems are home to life forms found nowhere else on Earth. Three new genera and at least 15 new species have been discovered here.
Description of the Status and Trends program, which monitors the abundance, distribution, productivity, and health of the Nation's living resources, detecting and evaluating changes in these variables over time.
This report is major publication on national biological resources that compiles and presents status and trends information for use by resource managers and the public. Presents detail information on ecosystems, plants, and animals.
Report prepared for the U.S. Fish and Wildlife Service with descriptions of exotic aquatic species introduced in the southeast United States with information on populations, geographic distribution, and origins.
Complex interactions among hydrologic events initiated by people and the behaviors and characteristics of animal species (both native and introduced) lead to important scientific and management problems.
