The Raptor Information System (RIS) collection and bibliographic database have been transferred to The Peregrine Fund. The RIS records are being subsumed into the bibliography posted on the website of the Global Raptor Information Network (GRIN).
One of the greatest challenges for conserving grassland, prairie scrub, and shrub-steppe ecosystems is maintaining prairie dog populations across the landscape. Of the four species of prairie dogs found in the United States, the Utah prairie dog (Cynomys
Explains how this potentially harmful invasive species arrived, why we are concerned, where in the area it is found, what environmental factors control its spread, and what might be done in response.

Invasive pigs first introduced to the continental United States in the 1500s by European explorers. Using tracking collars, we have begun to discover where these troublesome animals go.

Overview of the Southeastern Amphibian Research and Monitoring Initiative, annual report, field methods and protocols, statistical design and analysis, glossary, projects, and lists of frogs, toads and salamanders.
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.
Links to checklists and species maps showing the distribution of stoneflies in the United States with links to other information websites on stoneflies and reference list.
Combined with supporting research in reproductive physiology, identification of spawning habitat, and early life history this result provides new understanding of environmental factors that might affect reproduction of this endangered species.
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.
Report on the population of northern pintails between 1979 and the 1990s in Sacramento Valley, California, including methods of study including radio telemetry, causes of mortality, morphometrics, survival rates, and management implications.
Palmyra Atoll in the tropical Pacific is a "living laboratory" for multi-disciplinary research on coral reef ecosystems, insular terrestrial ecosystems, climate change, and the lingering effects of Cold War nuclear testing.
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.
Report on the captive breeding program at Patuxent Wildlife Research Center to help save endangered whooping cranes. Site links to natural history information on whooping cranes, why they are endangered, cool facts on cranes, and a photo gallery.
Links to checklists and species maps showing the distribution of tiger beetles in the United States with links to photographs, other information websites on invertebrates, and reference list.
This endangered species prefers native trees in large, continuous areas of riparian habitat. Armed with this information, resource managers may identify and preserve areas favorable to this population.
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

Links to research at the field stations of the Western Ecological Research Center with direct links to web pages for wildlife videos, satellite telemetry, fire ecology, invasive species, herpetology field guide, and coastal ecosystems.
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.
How will the increasing use of wind turbines affect populations of wild birds and bats? This shows which birds and bats we study, and the aspects of their ecology that may be affected by wind energy development.
