Natural attenuation of chlorinated-hydrocarbon contamination at Fort Wainwright, Alaska: A hydrogeochemical and microbiological investigation workplan
Kathleen A. McCarthy, Michael R. Lilly, Joan F. Braddock, Larry D. Hinzman
1998, Open-File Report 98-198
Natural attenuation processes include biological degradation, by which microorganisms break down contaminants into simpler product compounds; adsorption of contaminants to soil particles, which decreases the mass of contaminants dissolved in ground water; and dispersion, which decreases dissolved contaminant concentrations through dilution. The primary objectives of this study are to (1)...

West margin of North America - A synthesis of recent seismic transects
G. S. Fuis
1998, Tectonophysics (288) 265-292
A comparison of the deep structure along nine recent transects of the west margin of North America shows many important similarities and differences. Common tectonic elements identified in the deep structure along these transects include actively subducting oceanic crust, accreted oceanic/arc (or oceanic-like) lithosphere of Mesozoic through Cenozoic ages. Cenozoic...
Leucocytozoon simondi in Emperor Geese from the Yukon-Kuskokwim Delta in Alaska
Tuula E. Hollmen, J. Christian Franson, Lynn H. Creekmore, Joel A. Schmutz, Ada C. Fowler
1998, Condor (100) 402-404
We surveyed Emperor Geese (Chen canagica) in western Alaska for avian hematozoa. Blood smears were collected from 134 adults and goslings in late July 1996, on their breeding grounds on the Yukon-Kuskokwim Delta. One of 134 (0.7%) Emperor Geese harbored Leucocytozoon simondi, representing a new host record for this parasite. No...
Federal Coal in the United States: A Digital Database of Coal Ownership Status
Water Resources Division, U.S. Geological Survey
1998, Fact Sheet 012-98
As United States coal resources continue to be examined for potential development, a critical need exists for a digital database containing locations and status of all Federal coal resources. This Fact Sheet describes the development of such a digital database and presents examples of how the U.S. Geological Survey (USGS)...
Geographic trend in mercury measured in common loon feathers and blood
Joseph D. Kaplan, Michael W. Meyer, Peter S. Reaman, W. Emmett Braselton, A. Major, Neil Burgess, Anton M. Scheuhammer
1998, Environmental Toxicology and Chemistry (17) 173-183
The common loon (Gavia immer) is a high‐trophic‐level, long‐lived, obligate piscivore at risk from elevated levels of Hg through biomagnification and bioaccumulation. From 1991 to 1996 feather (n = 455) and blood (n = 381) samples from adult loons were collected between June and September in five regions of North America: Alaska,...

Chlorinated hydrocarbon contaminants in polar bears from eastern Russia, North America, Greenland, and Svalbard: Biomonitoring of Arctic pollution
R. J. Norstrom, Stanislav Belikov, E.W. Born, G.W. Garner, B. Malone, S. Olpinski, M.A. Ramsay, S. Schliebe, I. Stirling, M.S. Sitshov, M.K. Taylor, Øystein Wiig

Adipose tissue samples from polar bears (Ursus maritimus) were obtained by necropsy or biopsy between the spring of 1989 to the spring of 1993 from Wrangel Island in Russia, most of the range of the bear in North America, eastern Greenland, and Svalbard. Samples were divided into 16 regions corresponding...
Certainty of paternity and paternal investment in eastern bluebirds and tree swallows
Bart Kempenaers, Richard B. Lanctot, Raleigh J. Robertson
1998, Animal Behaviour (55) 845-860
Extra-pair paternity is common in many socially monogamous passerine birds with biparental care. Thus, males often invest in offspring to which they are not related. Models of optimal parental investment predict that, under certain assumptions, males should lower their investment in response to reduced certainty of paternity. We attempted to...
Male traits, mating tactics and reproductive success in the buff-breasted sandpiper, Tryngites subruficollis
Richard B. Lanctot, Patrick J. Weatherhead, Bart Kempenaers, Kim T. Scribner
1998, Animal Behaviour (56) 419-432
Buff-breasted sandpipers use a variety of mating tactics to acquire mates, including remaining at a single lek for most of the breeding season, attending multiple leks during the season, displaying solitarily or displaying both on leks and solitarily. We found that differences in body size, body condition, fluctuating asymmetry scores,...
Electrocardiographic consequences of a peripatetic lifestyle in gray wolves (Canis lupus)
Peter Constable, Ken Hinchcliff, Nick Demma, Margaret Callahan, Bruce W. Dale, Kevin Fox, Layne G. Adams, Ray Wack, Lynn Kramer
1998, Comparative Biochemistry and Physiology, Part A: Molecular & Integrative Physiology (120) 557-563
Cardiac chamber enlargement and hypertrophy are normal physiologic responses to repetitive endurance exercise activity in human beings and domestic dogs. Whether similar changes occur in wild animals as a consequence of increased activity is unknown. We found that free-ranging gray wolves (Canis lupus, n=11), the archetypical endurance athlete, have electrocardiographic...
Identification of polar bear den habitat in northern Alaska

1998, Occasional Papers of the IUCN Species Survival Comission (SSC) 19
The goal of this project is to refine the information collected previously on maternal denning, into digital maps that show where polar bears are likely to create future dens in northern Alaska. Such maps will allow a priori recommendations regarding timing and geographic locations of proposed human developments; and hence...

The historical distribution of sea otters extended from the northern islands of Japan north and east across the Aleutian chain to the mainland of North America then south along the west coast to central Baja California, Mexico (Riedman and Estes 1990). By the beginning of the twentieth century, after 150...
Pacific halibut in Glacier Bay National Park, Alaska

1998, Book chapter, Status and trends of the nation's biological resources
The Pacific halibut is a large (up to 3 meters long) predatory fish in the flatfish family. Glacier Bay National Park is the site of extensive and controversial commercial halibut fisheries that began before the park was established in 1925. These fisheries continue despite prohibitive regulations, including the Wilderness Act...

1998, Conference Paper, Proceedings of the international symposium on fishery stock assessment models for the 21st century; 15th Lowell Wakefield fisheries symposium
Ecosystem studies are difficult to interpret because of the complexity and number of pathways that may affect a phenomenon of interest. It is not possible to study all aspects of a problem; thus subjective judgment is required to weigh what has been observed in the context of components that were...

Roxy Peck, Larry D. Haugh, Arnold Goodman, editor(s)
1998, Book chapter, Statistical case studies: A collaboration between academe and industry
Izembek Lagoon, an estuary in Alaska, is a very important staging area for Pacific brant, a small migratory goose. Each fall, nearly the entire Pacific Flyway population of 130,000 brant flies to Izembek Lagoon and feeds on eelgrass to accumulate fat reserves for nonstop transoceanic migration to wintering areas as...

R. C. Johnson, R. M. Flores
1998, International Journal of Coal Geology (35) 241-282
The Rocky Mountain basins of western North America contain vast deposits of coal of Cretaceous through early Tertiary age. Coalbed methane is produced in Rocky Mountain basins at depths ranging from 45 m (150 ft) to 1981 m (6500 ft) from coal of lignite to low-volatile bituminous rank. Although some...
