This dissertation studies the impress of Cold War military investment on Alaska's cultural landscape. From 1946 through 1989, Alaska served as the United States' Cold War sentinel and the air defense shield against the threat of Soviet attack over the North Pole. During the Cold War the US military was a dominant force in the state economy and by the end of the period had built approximately 435 military facilities and installations in Alaska, ranging in size from those contained in individual, isolated buildings to massive, self-contained cities. This investment has had different types and degrees of impacts on different places. The study explores these patterns with respect primarily to the facilities' temporal...

Northern terrestrial ecosystems located in the circumpolar boreal region between 50° and 70° north contain about one third of the world's soil organic carbon (C). The recent rise in air temperatures at northern latitudes may be stimulating decomposition of soil organic carbon in these ecosystems. A net release of C stored in boreal soils due to increasing temperatures could have a significant positive feedback on global warming by increasing atmospheric carbon dioxide (CO 2 ) and methane (CH4 ). It is important, therefore, to understand the factors that control decomposition in northern terrestrial ecosystems. The main controls of decomposition in northern ecosystems include temperature, moisture, and substrate...
