Snow-Albedo Feedback In Northern Alaska: How Vegetation Influences Snowmelt, Lucas C. Reckhaus
Snow-Albedo Feedback In Northern Alaska: How Vegetation Influences Snowmelt, Lucas C. Reckhaus
Theses and Dissertations
This paper investigates how the snow-albedo feedback mechanism of the arctic is changing in response to rising climate temperatures. Specifically, the interplay of vegetation and snowmelt, and how these two variables can be correlated. This has the potential to refine climate modelling of the spring transition season. Research was conducted at the ecoregion scale in northern Alaska from 2000 to 2020. Each ecoregion is defined by distinct topographic and ecological conditions, allowing for meaningful contrast between the patterns of spring albedo transition across surface conditions and vegetation types. The five most northerly ecoregions of Alaska are chosen as they encompass …
Spatial Relationships, Movements, And Habitat Associations Of Introduced “Non-Native” Elk Populations On Etolin And Zarembo Islands, Alaska, Jean S. Davidson
Spatial Relationships, Movements, And Habitat Associations Of Introduced “Non-Native” Elk Populations On Etolin And Zarembo Islands, Alaska, Jean S. Davidson
Geography and the Environment: Graduate Student Capstones
Etolin and Roosevelt Elk were introduced to Afognak Island, Alaska in 1929 (State of Alaska, 2013). Due to the success of that introduction, Roosevelt Elk and Rocky Mountain Elk were subsequently introduced to Zarembo and Etolin Islands in Southeast Alaska in 1987. Due to the environment of Southeast Alaska, the ability to determine movements, trends, and habitat preferences are limited. In support of the Alaska Department of Fish and Game (ADF&G), this project analyzes the habitat preferences of the elk based upon data from global positioning systems. Locational data is analyzed for proximity to managed lands and considers proximity to …
