The ambermarked birch leafminer (AMBLM) (Profenusa thomsoni) is an invasive leafminer native to the Palearctic from the United Kingdom to Turkey to Japan. It was introduced to the eastern United States in 1921 and has since spread to the mid-western U.S. states and Canadian prov…

This thesis examines the art of Henry Wood Elliott (1846–1930) and its role in Elliott's successful crusade to save the Pribilof Island fur seals from probable extinction, its importance as a visual record of the nineteenth-century Pribilof Aleut people during a time of societal…
In this thesis changes in the nature of seismicity are examined in the context of changes in the stress/strain field occurring as part of the earthquake process. The history of earthquake recording in Northern Pakistan, central California, and the Alaska-Aleutian subduction zone…
This study explores the shifting anthropological constructs of identity for the Middle Tanana people through time. It first summarizes this theme through contemporary regional Native American internal and external influences. A discussion is then given on how these constructs be…
The purpose of the present study was to examine the relationship between risk of problematic substance use (RPSU) and six research variables: subjective happiness, resilience, physical activity, acculturation (i.e., heritage culture identification and mainstream culture identifi…
Anthropogenic climate change is rapidly altering alpine ecosystems in Alaska. Trees and woody shrubs are expanding upslope and displacing alpine tundra. As alpine tundra habitats shrink and fragment, arthropods and other animals face an increased risk of extirpation due to small…
Arctic Cod (Boreogadus saida) dominates fish assemblages in the Arctic and provides a valuable food source to upper trophic level predators. Little is known about several important facets of its biology and ecology in the Pacific Arctic, including in the Chukchi and Beaufort sea…
The integration of genetic and environmental information can help wildlife managers better understand the factors affecting a species’ population structure and their response to disturbance. This thesis uses genetic techniques to assess the broad and fine scale population struct…
The changing climate in the Arctic is resulting in increased air and water temperatures as well as a reduction in sea ice, affecting native species that evolved to live in the unique habitats of the Arctic Ocean. One species of significant importance to Arctic marine ecosystems …
This dissertation considers firewood selectivity at three pre-contact Alaskan sites: Gerstle River, Hungry Fox and Walakpa. These sites differ according to age, environmental setting and cultural affiliation, providing multiple perspectives from which to understand shared and id…
Understanding the potential effects of harvest on wildlife populations is fundamental to both theoretical wildlife science and applied wildlife management. The effects of harvest on wildlife populations vary dramatically and depend on the timing and magnitude of harvest, as well…
Once abundant in the Arctic, bison (Bison bison) declined almost to extinction in the North but have subsequently been reintroduced into Alaska. The predecessors of these modern bison were the ancient steppe bison (Bison priscus), which were abundant throughout the Northern Hemi…
Identification and interpretation of archaeological phenomena is typically based on visual cues and the physical presence of “something archaeological,” such as a diagnostic artifact, landscape modification, or structural element. Yet many archaeological features, i.e. the discr…
