2000, Fish and Wildlife Technical Report MMM 00-2
In March 2000, the U.S. Fish and Wildlife Service and U.S. Geological Survey hosted a workshop to evaluate various techniques and approaches to estimate the size and trend of the Pacific walrus population. Workshop participants included American and Russian experts in walrus biology and survey design, subsistence hunters, and resource...
Foods, trophic relationships, and migration of Sooty and Short-tailed Shearwaters associated with squid and large-mesh driftnet fisheries in the North Pacific Ocean
Patrick J. Gould, Peggy H. Ostrom, William Walker
2000, Waterbirds (23) 165-186
We salvaged dead birds from high seas driftnets in the Central North Pacific Ocean during a study of the impact of high seas driftnet fishing on marine ecosystems. Digestive tract contents and stable isotopes of nitrogen and carbon in breast muscles of these birds were analyzed to assess the effect...
Densities of Barrow's goldeneyes during winter in Prince William Sound, Alaska in relation to habitat, food, and history of oil contamination
Daniel Esler, Timothy D. Bowman, Charles E. O’Clair, Thomas A. Dean, Lyman L. McDonald
2000, Waterbirds (23) 423-429
We evaluated variation in densities of Barrow's Goldeneyes (Bucephala islandica) during winter at 214 sites within oiled and unoiled study areas in Prince William Sound, Alaska in relation to physical habitat attributes, prey biomass, and history of habitat contamination by the 1989 Exxon Valdez oil spill. Using general linear model...
Temporal variation in phenotypic and genotypic traits in two sockeye salmon populations, Tustumena Lake, Alaska
Carol Ann Woody, Jeffrey B. Olsen, Joel H. Reynolds, Paul Bentzen
2000, Transactions of the American Fisheries Society (129) 1031-1043
Sockeye salmon Oncorhynchus nerka in two tributary streams (about 20 km apart) of the same lake were compared for temporal variation in phenotypic (length, depth adjusted for length) and genotypic (six microsatellite loci) traits. Peak run time (July 16 versus 11 August) and run duration (43 versus 26 d) differed...

Monitoring seabird populations in areas of oil and gas development on the Alaskan Continental Shelf: A computerized pelagic seabird atlas for Alaska
John F. Piatt, R. Glenn Ford
2000, Report
Seabirds are the most visible and vulnerable victims of oil pollution in marine waters. As demonstrated by the "Exxon Valdez" spill (Piatt et al. 1990), we cannot predict when or where an accident leading to pollution might occur in Alaska, or where oil will eventually end up traveling from a...
Alagnak watershed rainbow trout seasonal movement

John H. Eiler, Doris J. Alcorn, Michael R. Neuman, editor(s)
2000, Conference Paper, Biotelemetry 15: Proceedings of the 15th international symposium on biotelemetry
Adult rainbow trout were radio-tagged in two locations in the Alagnak River drainage in 1997 and 1998 and radio-tracked until March 1999. The telemetry data indicate the two different sample groups exhibited independent movements with little geographic overlap. However, some tagged fish from each sample group migrated downstream to the...
Are North Slope surface alluvial fans pre-Holocene relicts?
Erk Reimnitz, Stephen C. Wolf
2000, Professional Paper 1605
The surface morphology of the northern slope of the Brooks Range (North Slope) from the Canning River, Alaska, eastward is dominated by a series of large alluvial fans and braided streams floored by coarse alluvium. On the basis of our studies, we conclude that the fans are not prograding now...

2000, Book chapter, The Tintina Gold Belt: Concepts, exploration, and discoveries: Special volume 2
The so-called Tintina Gold Belt extends for more than 1000 km along the length of the northern North American Cordillera. Middle to Late Cretaceous Au deposits within the belt have various similar characteristics, among which are a spatial and temporal association with magmatism; Bi-W-Te signatures in deposits hosted by granitod...
Hydrothermal activity and carbon-dioxide discharge at Shrub and upper Klawasi mud volcanoes, Wrangell Mountains, Alaska
Michael L. Sorey, Cindy Werner, Robert G. McGimsey, William C. Evans
2000, Water-Resources Investigations Report 2000-4207
Shrub mud volcano, one of three mud volcanoes of the Klawasi group in the Copper River Basin, Alaska, has been discharging warm mud and water and CO2?rich gas since 1996. A field visit to Shrub in June 1999 found the general level of hot-spring discharge to be similar, but somewhat...
Native plant revegetation manual for Denali National Park and Preserve
Roseann V. Densmore, Mark E. Vander Meer, Nancy G. Dunkle
2000, Information and Technology Report 2000-0006
This manual describes methods to revegetate subarctic sites with native plants. The information is based on 20 years of research and revegetation projects in Denali National Park and Preserve and other Alaskan sites. The manual summarizes information about subarctic ecosystems and discusses using this information to evaluate disturbed sites and plan revegetation projects....
Water resources data, Alaska, water year 1999
C.M. Bertrand, D.L. Hess, R.T. Kemnitz, D. F. Meyer, W.C. Swanner
2000, Water Data Report AK-99-1
The Water Resources Division of the U.S. Geological Survey, in cooperation with State and other agencies, obtains a large amount of data pertaining to the water resources of Alaska each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of...

Microsatellite analyses of Alameda Creek Rainbow/Steelhead trout
Jennifer L. Nielsen, Monique C. Fountain
1999, Report
Microsatellite genetic diversity found in Alameda Creek rainbow trout support a close genetic relationship with coastal trout found in Lagunitas Creek, Marin County, California. No significant genotypic or allelic frequencies associations could be drawn among Alameda Creek trout and fish collected from the four primary rainbow trout hatchery strains in...

Breeding of Steller's Eiders, Polysticta stelleri, on the Yukon-Kuskokwim Delta, Alaska
Paul L. Flint, M.P. Herzog
1999, Canadian Field-Naturalist (113) 306-308
Historically, an unknown number of Steller's Elders nested along the outer coastal fringe of the Yukon-Kuskokwim Delta, Alaska, but no nests had been found since 1975. We located six nests from 1991-1998 and we conclude that Steller's Elders are still a regular breeder at low densities on the Yukon-Kuskokwim Delta....
Relative importance of male and territory quality in pairing success of male rock ptarmigan (Lagopus mutus)
Jonathan Bart, Susan L. Earnst
1999, Behavioral Ecology and Sociobiology (45) 355-359
We studied pairing success in male rock ptarmigan (Lagopus mutus) in northern Alaska to learn whether males obtaining more females possessed phenotypic traits that influenced female choice directly, whether these traits permitted males to obtain territories favored by females, or whether both processes occurred. The number of females per male...
