Community, Population, And Growth Dynamics Of Alnus Tenuifolia: Implications For Nutrient Cycling On An Interior Alaskan Floodplain, Dana Rachel Nossov Dec 2008

Community, Population, And Growth Dynamics Of Alnus Tenuifolia: Implications For Nutrient Cycling On An Interior Alaskan Floodplain, Dana Rachel Nossov

Biological Sciences

This study describes the community, population, and growth dynamics of Alnus tenuifolia (thinleaf alder) and implications for nutrient cycling on the Tanana River floodplains. Through symbiotic N-fixation inputs, alder contributed to soil N accumulation with time. N-fixation itself was likely limited by soil P. Soil N was positively related to alder stem density in early successional stands. Community structure varied along a temporal gradient of changing environmental characteristics, but variations in successional patterns were found. Landscape scale alder recruitment varied temporally and was apparently linked to interactions between geofluvial processes, seed production and dispersal, and herbivory. A widespread stem canker …

Gene By Environment Interactions Between Three Candidate Genes For Obesity And Omega-3 Polyunsaturated Fatty Acids, Renee Leigh Pasker Dec 2008

Gene By Environment Interactions Between Three Candidate Genes For Obesity And Omega-3 Polyunsaturated Fatty Acids, Renee Leigh Pasker

Biological Sciences

Multi-factorial diseases, like obesity, are caused by genetic and environmental factors. Few studies examine potential interactions between genetic and environmental factors. Understanding these interactions can lead to better disease prevention. One important environmental factor related to obesity is omega-3 fatty acids. Yup’ik Eskimos consume a high amount of two omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). This study examined 10 single nucleotide polymorphisms (SNPs) in three genes: ADIPOQ, PPARG, and PPARGC1A. Also, 7 obesity phenotypes were examined: BMI, percent body fat, waist circumference, sum of skin-folds, plasma adiponectin, plasma triglycerides, and HDL cholesterol. Associations between these SNPs …

Buddy Reading For Reading Comprehension Growth And Reading Engagement, Kimberly L. Triplett Dec 2008

Buddy Reading For Reading Comprehension Growth And Reading Engagement, Kimberly L. Triplett

Education

"Teachers wonder how to motivate students to become better readers. Teachers of older remedial readers are challenged to provide reading material at students' reading levels relevant enough for them to want to read. Students are less likely to learn strategies to help them comprehend text if they are not engaged with the material. This project provided seventh grade remedial reading students a purpose for reading books at their level by reading children's picture books to first grade students. Prior to the buddy reading sessions, seventh grade students practiced reading with expression and fluency. In addition, their teacher taught cognitive strategies …

Classroom Culture And Indigenous Classrooms, Hishinlai' Kathy Sikorski Dec 2008

Classroom Culture And Indigenous Classrooms, Hishinlai' Kathy Sikorski

Education

"Indigenous languages have been traditionally learned by doing activities on the land, with the family or around a village. Sometimes, because this is not feasible, Indigenous languages can be learned in a classroom. This is a qualitative research on the author's own Indigenous language classroom with the theoretical foundations of second language acquisition and group formation processes. Data collected were videotapes, audiotapes, student journals, and an exit interview, which were triangulated and verified by an interrater. Results were that the instructor had to possess a philosophy of second language teaching and learning; set high expectations, and create a positive classroom …

Shallow Surface Thermogenic Hydrocarbon Migration Over Western Prudhoe Bay Region, Alaska, Sudipta Sarkar Dec 2008

Shallow Surface Thermogenic Hydrocarbon Migration Over Western Prudhoe Bay Region, Alaska, Sudipta Sarkar

Geosciences

"Hydrocarbons leak from petroleum reservoirs to the surface. In continuous permafrost regions like the Alaska North Slope, surface migration of thermogenic hydrocarbons may be hindered by the presence of ground ice. However, suitable permeable migration pathways in the permafrost can exist. Unfrozen sediments at the bottom of the lakes, or open faults can facilitate thermogenic hydrocarbon migration. I studied the nature and distribution of gaseous alkanes (C1 to C6) and helium in the shallow permafrost cores (2 m depth); depth profiles of alkanes (C1 to C7) in the two wells (1500 m deep); and stable isotopes of CH₄ trapped in …

Sensitivity Of Boreal Forest Carbon Dynamics To Long-Term (1989-2005) Throughfall Exclusion In Interior Alaska), Sarah A. Runck Dec 2008

Sensitivity Of Boreal Forest Carbon Dynamics To Long-Term (1989-2005) Throughfall Exclusion In Interior Alaska), Sarah A. Runck

Forest Sciences

"The objective of this study was to assess the effect of throughfall exclusion (1989-2005) on forest vegetation and soil in upland and floodplain landscape positions. In uplands, imposed drought reduced soil moisture at 5, 10, and 20 cm depths and increased soil C storage by slowing decomposer activity at the surface. In the drought plots, aboveground tree growth was reduced and root biomass in mineral soil was increased. In floodplains, imposed drought did not reduce soil moisture as strongly as it did in uplands, though near-surface soil C storage was still increased as a result of reduced decomposer activity. Floodplain …

Remote Sensing Aspen Leaf Miner (Phyllocnistis Populiella Chamb) Infestations Near Ester Dome In Fairbanks, Alaska, Douglas D. Smart Dec 2008

Remote Sensing Aspen Leaf Miner (Phyllocnistis Populiella Chamb) Infestations Near Ester Dome In Fairbanks, Alaska, Douglas D. Smart

Forest Sciences

"Mapping trembling aspen stands (Populous tremuloides Michx.) versus Alaskan birch (Betula neoalaskana Sarg.) in interior Alaska is possible as a byproduct of remote sensing aspen leaf miner (Phyllocnistis populiella Chamb.) damage. P. populiella is a defoliator of trembling aspen that has been observed in epidemic proportions in Alaska since 2001. Where it is observed it is ubiquitous. Unlike most remote sensing studies of insect damage, I found no significant change in the near-infrared related to leaf miner damage. The feeding morphology of P. populiella is different from most other leaf defoliating insects. P. populiella feeds only in the epidermal tissue …

“Fate Must Find Someone To Speak Through”: Christianity, Ragnarök, And The Loss Of Icelandic Independence In The Eyes Of The Icelanders As Illustrated By Gísla Saga Súrssonar, Grete E. Mjolsnes Dec 2008

“Fate Must Find Someone To Speak Through”: Christianity, Ragnarök, And The Loss Of Icelandic Independence In The Eyes Of The Icelanders As Illustrated By Gísla Saga Súrssonar, Grete E. Mjolsnes

English

Iceland surrendered political control to the Norwegian monarchy in 1262, but immediately resented their choice. The sagas about reliance on the Norwegians, clearly illustrating that the Icelanders knew where this path was leading them. Gísla Saga is a particularly interesting text to examine in light of the contemporaneous political climate, as it takes place in the years leading up to the conversion but was written between the conversion and the submission to Norwegian rule. Though Gísla does not explicitly comment on either the conversion or the increase in Norwegian influence, close examination illuminates ambiguity in the portrayal of Christian and …

An Engineering Study To Investigate The Methane Hydrate Resource Potential Associated With The Barrow Gas Fields In Alaska, Praveen Kumar Singh Dec 2008

An Engineering Study To Investigate The Methane Hydrate Resource Potential Associated With The Barrow Gas Fields In Alaska, Praveen Kumar Singh

Engineering

"Previous studies on the Barrow Gas Fields (BGF) in Alaska have suggested that accumulations of natural gas hydrates could exist within these reservoirs. In consideration of future energy challenges, and the potential of gas hydrates in meeting them, a comprehensive engineering study was undertaken to investigate the BGF for hydrates, and to recommend an optimal plan for future field development. The methane hydrate resource potential of the BGF, viz. the East Barrow (EB), South Barrow (SB), and Walakpa (WAL) gas pools, was analyzed by developing gas hydrate stability models. Material balance studies were performed on the EB gas field to …

Suffering, Pity, And Pride: Complexities Of The Russian-American Adoption Relationship From The Early 1990'S To 2007, Andrea K. Neighbors Dec 2008

Suffering, Pity, And Pride: Complexities Of The Russian-American Adoption Relationship From The Early 1990'S To 2007, Andrea K. Neighbors

Anthropology

This thesis describes and analyzes the Russian-American adoption relationship between the early 1990s and 2007. In the early 1990s, an Non-Governmental Organization report depicting Russian orphanages provided Americans with pitiful images of Russian orphaned children. The report became iconic and shaped the way Americans perceived Russian orphans and orphanages. For the rest of the 1990s, Russian children became one of the most popular adoption choices for American parents; these children had the “right” race and could be “saved”. In 2005, news started to surface that adopted Russian children had been murdered in the U.S. by American adoptive parents. The Russian …

Analysis And Interpretation Of Volcano Deformation In Alaska: Studies From Okmok And Mt. Veniaminof Volcanoes, Thomas J. Fournier Dec 2008

Analysis And Interpretation Of Volcano Deformation In Alaska: Studies From Okmok And Mt. Veniaminof Volcanoes, Thomas J. Fournier

Geosciences

Four studies focus on the deformation at Okmok Volcano, the Alaska Peninsula and Mt. Veniaminof. The main focus of the thesis is the volcano deformation at Okmok Volcano and Mt. Veniaminof, but also includes an investigation of the tectonic related compression of the Alaska Peninsula. The complete data set of GPS observations at Okmok Volcano are investigated with the Unscented Kalman Filter time series analysis method. The technique is shown to be useful for inverting geodetic data for time dependent non-linear model parameters. The GPS record at Okmok from 2000 to mid 2007 shows distinct inflation pulses which have several …

Geologic Setting Of The Central Alaskan Hot Springs Belt: Implications For Geothermal Resource Capacity And Sustainable Energy Production, Amanda M. Kolker Dec 2008

Geologic Setting Of The Central Alaskan Hot Springs Belt: Implications For Geothermal Resource Capacity And Sustainable Energy Production, Amanda M. Kolker

Geosciences

The Central Alaskan Hot Springs Belt (CAHSB) is a vast stretch of low-temperature hydrothermal systems that has the potential to be a geothermal energy resource for remote communities in Alaska. Little exploration has occurred in the CAHSB and the resource is poorly understood. A geothermal power plant was installed in 2006 at Chena Hot Springs (CHS), one of the 30-plus hot springs in the CAHSB. This, in addition to the multiple direct use projects at CHS, could serve as a model for geothermal development elsewhere in the CAHSB. This dissertation evaluates the geologic setting of the CAHSB and explores the …

The Effects Of Scale And Spatial Heterogeneities On Diffusion In Volcanic Breccias And Basalts: Amchitka, Alaska, Jennifer Lyn Benning Dec 2008

The Effects Of Scale And Spatial Heterogeneities On Diffusion In Volcanic Breccias And Basalts: Amchitka, Alaska, Jennifer Lyn Benning

Engineering

Aqueous phase diffusion of molecules in fractured crystalline rock can play a dominant role in the fate and transport of contaminants, particularly if advective flows are very slow. The importance of the role of diffusion, typically a very slow process, also becomes an important mechanism to consider if the contaminants are long-lived in the subsurface, and thus their fate and transport must be considered over very long time-scales. Owing to the inherently heterogeneous nature of the subsurface, quantification of diffusive transport in the subsurface is extremely complex. The main objective of this study was to investigate the effects of the …

Habitat Analysis Of Major Fishing Grounds On The Continental Shelf Off Kodiak, Alaska, Sean Charles Rooney Dec 2008

Habitat Analysis Of Major Fishing Grounds On The Continental Shelf Off Kodiak, Alaska, Sean Charles Rooney

Fisheries

"The continental shelf and upper slope of the Gulf of Alaska support diverse and commercially important communities of demersal fishes. Twenty-eight video-strip transects conducted from a research submersible, together with habitat maps based on interpreted multibeam sonar data, were used to classify distribution and abundance patterns of fishes relative to seafloor substrate type and water depth on Albatross and Portlock Banks on the Kodiak Shelf in the Gulf of Alaska. These associations were examined across spatial scales: ranging from tens of kilometer centimeters in size. A total of 5,778 fishes were recorded from 33 taxa. Fish community distribution patterns were …

Non-Volcanic Tremor In The Alaska/Aleutian Subduction Zone And Its Relationship To Slow-Slip Events, Chloe L. Peterson Dec 2008

Non-Volcanic Tremor In The Alaska/Aleutian Subduction Zone And Its Relationship To Slow-Slip Events, Chloe L. Peterson

Geosciences

"We document non-volcanic tremor (NVT) in Southcentral Alaska and the Aleutian Arc in terms of durations and locations. In Southcentral Alaska, we tabulate NVT events occurring during the summer months of each year between 1999 and 2001 to test for a relationship with a slow-slip event that occurred during this time frame. We tabulate NVT events in the Aleutians starting in the summer of 2005 through the summer of 2008. The observed NVT events in both Southcentral Alaska and the Aleutian arc are sequences of emergent pulses with frequencies of 1-10 Hz. The majority of the events have durations ranging …

Quikscat Measurements Of The Wind Field Over The Bering And Chukchi Seas, Jeremy M. Mull Dec 2008

Quikscat Measurements Of The Wind Field Over The Bering And Chukchi Seas, Jeremy M. Mull

Marine Biology

The purpose of this study is to investigate the dynamic wind field and resulting ocean circulation patterns in the Bering and Chukchi Seas. This region forms an important link in global ocean circulation as Bering Strait is a major conduit for water flowing into the Arctic Ocean. The Arctic has been identified as an area sensitive to climate change; thus it is vital to understand how water and energy flow through this region. We first quantify the differences between the winds measured in this region by the Quik Scatterometer (QuikSCAT) and those modeled by the National Centers for Environmental Prediction …

The Status Of Pacific Walrus (Odebenus Rosmarus Divergens) Foraging Habitat And Diet Around St. Lawrence Island, Tracie E. Merrill Dec 2008

The Status Of Pacific Walrus (Odebenus Rosmarus Divergens) Foraging Habitat And Diet Around St. Lawrence Island, Tracie E. Merrill

Marine Biology

With ongoing climate change, food resources may be reduced for Pacific walruses (Odobenus rosmarus divergens). Significant differences in walrus foraging habitat (benthic communities) or diet might indicate changes in prey quality or quantity. In this study, benthic infaunal biomass, abundance, and composition were compared between 1970-1974 and 2006 at stations southwest of St. Lawrence Island. Sediment grain size was compared because it strongly determines benthic community structure. Wet weights, counts, and species composition of prey items found in stomachs of walruses collected near the island were compared between the 1980s and 2007. Benthic invertebrate biomass and abundance increased mainly due …
