2003, The Wilson Bulletin (115) 481-483
We report an apparent nonlethal predation attempt on and subsequent adoption of a Glaucous-winged Gull (Larus glaucescens) chick by a pair of Bald Eagles (Haliaeetus leucocephalus) in the Aleutian Archipelago, Alaska. To the best of our knowledge, this is the first report of a live Glaucous-winged Gull chick...

Geochronology and eruptive history of the Katmai volcanic cluster, Alaska Peninsula
Wes Hildreth, Marvin A. Lanphere, Judy Fierstein
2003, Earth and Planetary Science Letters (214) 93-114
In the Katmai district of the Alaska Peninsula, K–Ar and 40Ar/39Ar ages have been determined for a dozen andesite–dacite stratocones on the arc front and for 11 rear-arc volcanoes, 10 of which are monogenetic. Tied to mapping and stratigraphic studies, our dating emphasized proximal basal lavas that rest on basement rocks,...

2003, American Association of Petroleum Geologists Bulletin (87) 1823-1846
Along the southeast border of the 1002 Assessment Area in the Arctic National Wildlife Refuge, Alaska, an explicit link between gas generation and deformation in the Brooks Range fold and thrust belt is provided through petrographic, fluid inclusion, and stable isotope analyses of fracture cements integrated with zircon fission-track...
Habitat characteristics of polar bear terrestrial maternal den sites in northern Alaska
George M. Durner, Steven C. Amstrup, Anthony S. Fischbach
2003, Arctic (56) 55-62
Polar bears (Ursus maritimus) give birth to and nurture their young in dens of ice and snow. During 1999-2001, we measured the structure of 22 dens on the coastal plain of northern Alaska after polar bear families had evacuated their dens in the spring. During the summers of 2001 and...
Toxoplasma gondii, Neospora caninum, Sarcocystis neurona, and Sarcocystis canis-like infections in marine mammals

2003, Veterinary Parasitology (116) 275-296
Toxoplasma gondii, Neospora caninum, Sarcocystis neurona, and S. canis are related protozoans that can cause mortality in many species of domestic and wild animals. Recently, T. gondii and S. neurona were recognized to cause encephalitis in marine mammals. As yet, there is no report of natural exposure of N. caninum...
Interannual growth dynamics of vegetation in the Kuparuk River watershed, Alaska based on the Normalized Difference Vegetation Index
A.S. Hope, W.L. Boynton, D.A. Stow, David C. Douglas
2003, International Journal of Remote Sensing (24) 3413-3425
Interannual above-ground production patterns are characterized for three tundra ecosystems in the Kuparuk River watershed of Alaska using NOAA-AVHRR Normalized Difference Vegetation Index (NDVI) data. NDVI values integrated over each growing season (SINDVI) were used to represent seasonal production patterns between 1989 and 1996. Spatial differences in ecosystem production were...
Experimental and textural constraints on mafic enclave formation in volcanic rocks
M.L. Coombs, J.C. Eichelberger, M.J. Rutherford
2003, Journal of Volcanology and Geothermal Research (119) 125-144
We have used experiments and textural analysis to investigate the process of enclave formation during magma mixing at Southwest Trident volcano, Alaska. Andesite enclaves are present throughout the four dacite lava flows produced by the eruption, and resemble mafic enclaves commonly found in other volcanic rocks. Our experiments replicate the...
Biogeochemical processes that produce dissolved organic matter from wheat straw

The Alagnak River, a National Wild River located in southwestern Alaska, drains an area of 3,600 square kilometers and is used for recreational and subsistence activities, primarily angling, camping, rafting, and hunting by visitors and seasonal residents, and for commercial guiding by several lodges. Increases in visitor use in the...
Soil organic carbon on lands of the Department of the Interior
Norman B. Bliss
2003, Open-File Report 2003-304
The stocks of soil organic carbon (SOC) on the landscape are an important element in the global carbon cycle. Changes in soil carbon can change the concentrations of greenhouse gases in the atmosphere. If carbon dioxide from the atmosphere, captured through photosynthesis, is ultimately stored in the soil to an...

Dennis C. Trabant, Rod S. March, Donald S. Thomas
2003, Fact Sheet 001-03
Hubbard Glacier, the largest calving glacier on the North American Continent (25 percent larger than Rhode Island), advanced across the entrance to 35-mile-long Russell Fiord during June 2002, temporarily turning it into a lake. Hubbard Glacier has been advancing for more than 100 years and has twice closed the entrance...
Estimating the Magnitude and Frequency of Peak Streamflows for Ungaged Sites on Streams in Alaska and Conterminous Basins in Canada
Janet H. Curran, David F. Meyer, Gary D. Tasker
2003, Water-Resources Investigations Report 2003-4188
Estimates of the magnitude and frequency of peak streamflow are needed across Alaska for floodplain management, cost-effective design of floodway structures such as bridges and culverts, and other water-resource management issues. Peak-streamflow magnitudes for the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year recurrence-interval flows were computed for 301...

Double sampling to estimate density and population trends in birds
Jonathan Bart, Susan L. Earnst
2002, The Auk (119) 36-45
We present a method for estimating density of nesting birds based on double sampling. The approach involves surveying a large sample of plots using a rapid method such as uncorrected point counts, variable circular plot counts, or the recently suggested double-observer method. A subsample of those plots is also surveyed...

α1-Antitrypsin polymorphism and systematics of eastern North American wolves
L.D. Mech, N.E. Federoff
2002, Canadian Journal of Zoology (80) 961-963
We used data on the polymorphic status of α1-antitrypsin (α1AT) to study the relationship of Minnesota wolves to the gray wolf (Canis lupus), which was thought to have evolved in Eurasia, and to red wolves (Canis rufus) and coyotes (Canis latrans), which putatively evolved in North America. Recent evidence had...
Role of selenium toxicity and oxidative stress in aquatic birds
D. J. Hoffman
2002, Aquatic Toxicology (57) 11-26
Adverse effects of selenium (Se) in wild aquatic birds have been documented as a consequence of pollution of the aquatic environment by subsurface agricultural drainwater and other sources. These effects include mortality, impaired reproduction with teratogenesis, reduced growth, histopathological lesions and alterations in hepatic glutathione metabolism. A review...
