T HE CHANCE TO SEE a wild grizzly bear is often the first or second reason people give for visiting Yellow - stone National Park. Public interest in bears is closely coupled with a desire to perpetuate this wild symbol of the American West. Grizzly bears have long been described as a wilderness species requiring large tracts of undisturbed habitat. However, in today’s world, most grizzly bears live in close proximity to humans (Schwartz et al. 2003). Even in Yellowstone National Park, the impacts of humans can affect the long-term survival of bears (Gunther et al. 2002). As a consequence, the park has long supported grizzly bear research in an effort to understand these impacts. Most people are familiar with what...

Mountain ecosystems within our national parks and other protected areas provide valuable goods and services such as clean water, biodiversity conservation, and recreational opportunities, but their potential responses to expected climatic changes are inadequately understood. The Western Mountain Initiative (WMI) is a collaboration of scientists whose research focuses on understanding and predicting responses of western mountain ecosystems to climatic variability and change. It is a legacy of the Global Change Research Program initiated by the National Park Service (NPS) in 1991 and continued by the U.S. Geological Survey (USGS) to this day as part of the U.S. Climate Change Science Program (http://www.climatescience.gov/)....

During the 2012 field season, the Central Alaska Network (CAKN) Stream Monitoring Program made 130 site visits to 58 unique stream sites across the network (Figure 1), with each site being sampled one to five times from early May through late September. The data collected included instantaneous water chemistry, stream flow, water chemistry samples, macroinvertebrates, benthic diatoms, stable isotope samples, habitat data and environmental DNA samples. Continuous year-round temperature monitoring at 23 sites across the network is ongoing. At the request of DENA staff, the Stream Monitoring Program collected water chemistry, metals, invertebrates and diatoms from 7 sites in the Kantishna Hills. Active layer depth...

High resolution vegetation polygons mapped by the National Park Service. A total of 800 acres (324 ha) were mapped. Thirteen map classes were used to describe the landscape. Among these were six plant association, one alliance, two non-natural map classes (Disturbed, Development), three local types, and one un-vegetated natural class (Open Water).

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
