South from Alaska: a pilot aDNA study of genetic history on the Alaska Peninsula and the eastern Aleutians.

Protective Effects of Educational Attainment Against Cigarette Smoking; Diminished Returns of American Indians and Alaska Natives in the National Health Interview Survey

Introduction: Although educational attainment is protective against health risk behaviors such as smoking, the Minorities’ Diminished Return theory posits that these protective effects are smaller for ethnic minorities than majority groups. This study compared the effects of educational attainment on the smoking status of American Indian/Alaska Native (AIAN) and White ...

Status and Trends of the Nation's Biological Resources - Alaska

A laska is the largest state (1,477,270 square kilometers), more than twice as large as Texas and one-fifth the size of the lower 48 contiguous states. Alaska extends more than 20° in latitude, from Point Barrow at 71°23' to Amatignak Island in the Aleutians at 51°20'. It spans 42° in longitude, from 130° at the Portland Canal in the southeast to 172° at Attu Island in the western Aleutians (Fi...

Post-glacial colonization of northwestern North America by the forest-associated American marten (Martes americana, Mammalia: Carnivora: Mustelidae).

Phylogeographic patterns were used to assess intraspecific diversification of American martens (Martes americana). Within martens, two morphological groups (americana and caurina) have been recognized, though the level of distinction between them has been debated. We examined mitochondrial cytochrome b gene haplotypes from 680 martens to explore the colonization history of the Pacific Northwest...

A Numerical Experiment on Seismic Tsunami Warning Network for Alaska and the Aleutians

On the relationship between Arctic ice clouds and polluted air masses over the North Slope of Alaska in April 2008

Recently, two types of ice clouds (TICs) properties have been characterized using the Indirect and SemiDirect Aerosol Campaign (ISDAC) airborne measurements (Alaska, April 2008). TIC-2B were characterized by fewer (< 10 L−1) and larger (> 110 μm) ice crystals, and a larger ice supersaturation (> 15 %) compared to TIC-1/2A. It has been hypothesized that emissions of SO2 may reduce the ice nuclea...
