The USGS-NPS Vegetation Mapping Program is a cooperative effort with the National Park Service (NPS) to classify, describe, and map vegetation communities in over 270 U.S. national park units with links to overview, standards, products, and applications.
Describes investigative techniques focused on genetic characteristics of individuals and populations, and explains how this information helps improve existing natural populations and potentially impede invasive populations.
Over 30 years of substantial warming, the timing of life cycle events in maize here has changed, threatening the crop yield by exposing the plant at sensitive phases in its life cycle to increased heat and drought, and lowering the weight of its grains.
Summarizes studies that took place in this ecoregion. Some studies occurred in areas without post-fire management, and others in moderately or intensively managed areas. Some of the research also occurred immediately after a wildfire, and other work occur
Report of a pilot study to classify vegetation communities in parts of the Smoky Mountains National Park by sampling vegetation in selected areas with information on field methods and data analysis and lists of communities identified.
Review of current research on stock assessment of the Pacific walrus in the Chukchi and Bering Seas and interactions between walruses and their environment with links to walrus taxonomy, distribution, behavior, and relation to man

Links to reports of aquatic ecosystems research at the Western Fisheries Research Center (WFRC) emphasizing the understanding of ecological processes for aquatic systems, including river basins, riparian areas, wetlands, and estuaries.
Homepage for project on Bear Lake, Idaho-Utah, to study past climate change and effect on lake catchment basins. Includes link to summary, personnel, geology, methods used including coring and seismic surveying, and publications.
Information on the NWRC Wetlands Ecology Branch, which conducts research related to sustainable management and restoration of the nation's coastal saltwater wetlands, freshwater wetlands, submerged aquatic ecosystems, and coastal prairie.
Shooting them doesn't work, they just breed more. And they trample on the native plants. These animals were brought to the islands during the last 150 years, and we're trying to develop ways of managing their impact on the native life.
Thematic descriptions of research to meet the varied needs of the fire management community and to understand the role of fire in the landscape including fire management support, studies of postfire effects, and fire history and ecology.
Site with links to projects of the field center of the Woods Hole Coastal Marine Geology Program on underwater areas between shorelines and the deep ocean, off the U.S. East Coast, the Gulf of Mexico, and in parts of the Caribbean and Great Lakes.
