Boreal regions contain more than half of the carbon in forested regions of the world and over 60% of the world's surface freshwater. Carbon storage and the flood control and water filtration provided by freshwaters and wetlands have recently been identified as the most important ecosystem services provided by boreal regions, with a value many times greater than current resource exploitation. Ecosystem services and sensitive ways of detecting their impairment have so far not been fully included in boreal conservation planning. Climate warming, via its effect on permafrost melting, insect damage, and forest fire, threatens to trigger large positive carbon feedbacks that may enhance the concentrations of greenhouse...
This research explores the effects of climate change throughout the Holocene by investigating a multi-component site at Butte Lake, Alaska. This research combines expectations generated from ethnographic models to evaluate site use conditioned by environmental constraints within the theoretical framework of human behavioral ecology. Analysis of lithic materials, faunal remains, and site structure are evaluated to determine site type by occupational component. The results of this research show that a period of low effective moisture during the early Holocene (9000 to 5000 cal BP), as well as a period of both low temperature and increased effective moisture associated with the Neoglacial (3500 to 1500 cal BP) had...
Sustainable resource management depends upon the participation of resource-dependent communities. Competing values between community members and government agencies and among groups within a community can make it difficult to find mutually acceptable management goals and can disadvantage certain resource users. This study uses Q-methodology to discover groups with shared perspectives on wildfire policy in the Koyukon Athabascan villages of Galena and Huslia, Alaska. Before the study, participants appeared to disagree over the amount of wildfire suppression needed, but Q-method results showed three perspectives united around deeper, less oppositional concerns: Caucasian residents and resource managers who preferred...

PURPOSE: The construction and operation of 30 to 45 miles of rail line between the Port MacKenzie District in Matanuska-Susitna Borough and a point just north of Willow, Alaska are proposed. On December 5, 2008, the Alaska Railroad Corporation (ARRC) filed a petition for the Port MacKenzie rail extension to provide freight services between Port MacKenzie and Interior Alaska. The proposed project would connect Port MacKenzie, the closest deep-water port to Interior Alaska, with the existing ARRC rail system. The Port's market includes bulk commodities, iron or steel materials, vehicles and heavy equipment, and mobile or modular buildings. The nearest other port in the area is the Port of Anchorage, which is an additional...
