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...

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...

Biogeochemical processes that produce dissolved organic matter from wheat straw
Robert L. Wershaw, David W. Rutherford, Jerry A. Leenheer, Kay R. Kennedy, Larry G. Cox, Donald R. Koci
2003, Water-Resources Investigations Report 2003-4213
The chemical reactions that lead to the formation of dissolved organic matter (DOM) in natural waters are poorly understood. Studies on the formation of DOM generally are complicated because almost all DOM isolates have been derived from mixtures of plant species composed of a wide variety of different types of...
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...

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...
Blood selenium concentrations and enzyme activities related to glutathione metabolism in wild emperor geese
J. Christian Franson, David J. Hoffman, Joel A. Schmutz
2002, Environmental Toxicology and Chemistry (21) 2179-2184
In 1998, we collected blood samples from 63 emperor geese (Chen canagica) on their breeding grounds on the Yukon-Kuskokwim Delta (YKD) in western Alaska, USA. We studied the relationship between selenium concentrations in whole blood and the activities of glutathione peroxidase and glutathione reductase in plasma. Experimental studies have shown...

Robert S. Steneck, Michael H. Graham, Bruce J. Bourque, Debbie Corbett, Jon M. Erlandson, James A. Estes, M. J. Tegner
2002, Environmental Conservation (29) 436-459
Kelp forests are phyletically diverse, structurally complex and highly productive components of coldwater rocky marine coastlines. This paper reviews the conditions in which kelp forests develop globally and where, why and at what rate they become deforested. The ecology and long archaeological history of kelp forests are examined through case...
