1999, Conference Paper, Strategies for bird conservation: The Partners in Flight planning process: Proceedings of the 1995 Partners in Flight (PIF) International Workshop
Boreal regions of western North America regularly support breeding populations of 130 species of landbirds, including 68 Nearctic-Neotropical migrants. Primary conservation concerns within the region include increased timber harvesting, insect outbreaks, fire suppression, mining, impacts of military training activities, urbanization, and recreational activities. Under auspices of Partners in Flight, biologists,...

Grant V. Hilderbrand, Thomas A. Hanley, Charles T. Robbins, C.C. Schwartz
1999, Oecologia (121) 546-550
We quantified the amount, spatial distribution, and importance of salmon (Oncorhynchus spp.)-derived nitrogen (N) by brown bears (Ursus arctos) on the Kenai Peninsula, Alaska. We tested and confirmed the hypothesis that the stable isotope signature (δ15N) of N in foliage of white spruce (Picea glauca)...

The distribution of mineral deposits within northwestern North America (Alaska, Yukon, and northern British Columbia) allows for an in-depth examination of the metallogenic patterns of a growing continental margin. A more complete understanding of the tectonic evolution of this part of the Pacific Rim, achieved over the last 15 to...

1997 volcanic activity in Alaska and Kamchatka: summary of events and response of the Alaska Volcano Observatory
Robert G. McGimsey, Kristi L. Wallace
1999, Open-File Report 99-448
The Alaska Volcano Observatory (AVO) monitors over 40 historically active volcanoes along the Aleutian Arc. Twenty are seismically monitored and for the rest, the AVO monitoring program relies mainly on pilot reports, observations of local residents and ship crews, and daily analysis of satellite images. In 1997, AVO responded to...
Effects of sample size and sampling frequency on studies of brown bear home ranges and habitat use
Steve M. Arthur, Charles C. Schwartz
1999, Ursus (11) 139-148
We equipped 9 brown bears (Ursus arctos) on the Kenai Peninsula, Alaska, with collars containing both conventional very-high-frequency (VHF) transmitters and global positioning system (GPS) receivers programmed to determine an animal's position at 5.75-hr intervals. We calculated minimum convex polygon (MCP) and fixed and adaptive kernel home ranges for randomly-selected...

Physical, chemical, and biological data for two sites on the upper Kenai River, Alaska, 1998
Joseph M. Dorava, Lee Ness
1999, Open-File Report 99-258
Water-quality data were collected and stream characteristics were documented from two sites along the upper Kenai River in the Kenai National Wildlife Refuge, Alaska. These data were collected to describe the current status of the sites and to provide baseline information from which changes in the future could be evaluated....

1999, Open-File Report 99-80
The U.S. Army Alaska is responsible for environmental activities on Fort Wainwright near Fairbanks, Alaska. In order to better meet the needs of environmental investigations, the Army requires geohydrologic information about the Fort Wainwright area. Since 1994, the U.S. Geological Survey has been working in cooperation with the U.S. Army...
