Political ecology is a holistic mode of inquiry that applies political analysis to resource use and access by actors and organizations interacting in defined social and cultural contexts. This thesis uses a political ecology perspective to reveal how the Atna' Athabaskan people of South central Alaska use their knowledge of their environment to articulate a specific claim to Copper River salmon. Three case studies of Atna' public activism are presented demonstrating Atna' practice in governmental regulatory process. The position of the Atna' in the Copper River salmon fishery is contrasted with three other north Pacific Native American salmon regimes in order to demonstrate the special features of the Atna' context.

Mining landscapes are avowedly complex and dynamic cultural resources, representing an important part of the nation's cultural heritage. They reflect changes in technology, social organization, and the influence of outside events. Mining landscapes are also representative of the experiences of change over time. This representative experience is not well-represented in the typical approach to considering preservation of mining districts during the review of federal projects. This thesis takes a different approach, developing a classification system with a greater focus on the changes that occur, and tests this against a small-scale lode mining district in Southcentral Alaska. While the ability to factor in change...

Previous studies indicate streams in the watershed of Anchorage, AK, contain elevated concentrations of several Potentially Toxic Metals (PTMs) in the water, suspended and streambed sediment and benthic macro invertebrates. This study investigated the sources, distribution, and uptake of PTMs by aquatic organisms in the watershed and their relationship to land-use patterns. Sampling sites were chosen that represent the watercourses of each of the four major streams in Anchorage. Water, streambed sediment, various species of benthic macroinvertebrates and slimy sculpin ( Cottus cognatus ) were collected throughout the summer of 2005. A lake sediment core was also collected from Campbell Lake to assess PTM deposition...

The University of Alaska Anchorage supported the development of a bibliography of natural and cultural resource information important the Northwest Boreal Region. This tool provides the ability to search a vast, curated database for the Northwest Boreal region in one place. Users can explore thousands of curated scholarly articles, state and federal resource reports, land management plans, and unique transboundary datasets. Each entry includes geographic information about the area of study, allowing users to draw a box on a map to narrow searches to information directly related to a specific region in Alaska, the Yukon, British Columbia, and Northwest Territories. Potential users include land and resource managers,...

The bedload geomorphic processes of Ship Creek in the vicinity of the Knik Arm Power Plant (KAPP) Dam are unknown. These processes are necessary to understand the consequences of removing the KAPP Dam. With the aid of hydrologic flow modeling software, the induced shear stress was analyzed for a given flood event with and without the KAPP Dam in place. The shear stress was used to estimate the volume of bedload sediment transport related to a given flood event. The model showed that the removal of the KAPP Dam will increase the shear stress upstream for approximately 200 feet for a low-order event, and 400 feet for a high order event. This increase in shear stress indicates that the creek will become more susceptible...
