Canenermiut Lifeways And Worldview And Western Fish And Wildlife Management, Carl T. Jack Dec 2002

Canenermiut Lifeways And Worldview And Western Fish And Wildlife Management, Carl T. Jack

Rural Development

The Canenermiut inter-generational worldview embodies the proper use and conservation of the resources necessary to sustain life from time immemorial. The classical Yupiaq conservation ethics in the utilization of subsistence resources are well established and practiced to this day by Canenermiut that is geared to the survival of their culture and community. When western fish and wildlife managers promulgate regulations from urban areas of Alaska on the taking of subsistence resources in rural Alaska they often find out that rural residents such as the Canenermiut ... are unwilling to follow the regulations. Caneneq is a coastal area between Kusquqvak (Kuskokwim) …

Cultural And Linguistic Sensitivity In Assessment Tools: An Adaptation Of The Drinkers Inventory Of Consequences For Alaska Natives, Tony Cantil Dec 2002

Cultural And Linguistic Sensitivity In Assessment Tools: An Adaptation Of The Drinkers Inventory Of Consequences For Alaska Natives, Tony Cantil

Psychology

The purpose of this study was to determine the validity of a new assessment tool for Alaska Native clients with alcoholism. A sample of 23 Yup'ik clients at a regional treatment center were interviewed using the Drinker Inventory of Consequences for Alaska Natives (DrInC-AN), an adaption of the Drinker Inventory of Consequence (DrInC), the Alcohol Use Disorders Identification Test (AUDIT) and the Yup'ik Cultural Practices and Traditions (YCPT). These clients were selected, on a voluntary basis during the intake interview to the treatment center. Historically, assessment tools in alcoholism have not been culturally or linguistically sensitive to Alaska Native and …

Determining The Impacts Of Storage Practice And Treatment Technology On The Formation Of Disinfection Byproducts, Greta Myerchin Mcgee Dec 2002

Determining The Impacts Of Storage Practice And Treatment Technology On The Formation Of Disinfection Byproducts, Greta Myerchin Mcgee

Theses (Unassigned)

Disinfection byproducts (DBP) are formed during the reaction of chemical disinfectants with natural organic material (NOM). DBPs are potential carcinogens and are regulated by the US Environmental Protection Agency (USEP A) under the Disinfectant/DBP (D/DBP) rule. High concentrations of NOM in drinking water sources used by Alaska's communities often result in the formation of DBPs during treatment. Since surface water sources in the Arctic are frozen for 6-9 months of the year, communities are often forced to store raw water for treatment during the winter or treat and store enough drinking water during the summer to last through the winter. …

Comparison Of Snowshoe Hare Populations In Interior Alaska, Bjorn Flora Dec 2002

Comparison Of Snowshoe Hare Populations In Interior Alaska, Bjorn Flora

Biological Sciences

Snowshoe hares, Lepus americanus, are a 'keystone' prey species in northern boreal forests and experience population fluctuations of 8-11-years. Despite intense responses of both vegetation and predators to changes in hare densities, landscape-scale comparisons of hare populations in Alaska have been limited to qualitative descriptions. We conducted capture-recapture studies of snowshoe hares at 5 locales in the Tanana valley, from Tok in the east to Clear in the west from 1999 to 2002. Snowshoe hare densities were highest in 1999 (x=6.36 ha⁻¹, SE=0.63) and declined thereafter. We were unable to detect declines in apparent survival during declining densities in our …

Energetics Of Hibernation In The Arctic Ground Squirrel (Spermophilus Parryii Kenicotti), Shawna Karpovich Dec 2002

Energetics Of Hibernation In The Arctic Ground Squirrel (Spermophilus Parryii Kenicotti), Shawna Karpovich

Biological Sciences

Arctic ground squirrels (Spermophilus parryii kenicotti) hibernate underground; experiencing burrows temperatures of -5 to -25C̊. Hibernation consists of 7-9 months of torpor interrupted every 2-3 weeks by 10-20 h arousal episodes with high body temperatures and metabolic rates. Metabolic rates and body temperatures were measured during arousal episodes under temperate and arctic conditions. No difference in cost of arousal episodes was detected. Yet, when the cost of thermogenesis during torpor was included, proportional cost of arousal episodes decreased from 86 to 27% comparing temperate to arctic conditions. The relationship between metabolic rate and body temperature was examined during the recooling …

The Limnology Of Lake Clark, Alaska, Alexander Xanthus Wilkens Dec 2002

The Limnology Of Lake Clark, Alaska, Alexander Xanthus Wilkens

Biological Sciences

This study gathered baseline limnological data to investigate the thermal structure, water quality, phytoplankton, and zooplankton of Lake Clark, Alaska. Results indicate Lake Clark is oligotrophic and mixes biannually, but stratification is weak and thermoclines are deep. Longitudinal gradients were seen in measurements of temperature, suspended solids, turbidity, light penetration, algal biomass, and zooplankton density. Wind and tributary inputs determine the thermal regime. Glacially-influenced tributaries drive turbidity and light gradients by introducing suspended solids to the inlet end of the lake. Suspended solids likely create the algal biomass gradient by limiting the light available for photosynthesis in the inlet basin. …

Winter Foraging Ecology Of Moose In The Tanana Flats And Alaska Range Foothills, C. Tom Seaton Dec 2002

Winter Foraging Ecology Of Moose In The Tanana Flats And Alaska Range Foothills, C. Tom Seaton

Biological Sciences

I studied woody browse distribution, production, removal, species composition, twig size, moose diets, and predicted daily intake of resident and migratory moose in the Tanana Flats and adjacent Alaska Range Foothills, Alaska, 1999-2000. Density of moose in these areas was high (1.1 moose/km²). Moose were experiencing density-dependent effects on reproduction and growth, exhibited by low adult twinning rate (6%) and absence of pregnant yearlings, yet 17.5 kg higher 10-month-old calf body weights in the migratory segment. Of all willow, poplar, and paper birch plants sampled, 74% had a broomed architecture, which I attributed to heavy use by moose. Using a …

The Ecological Genetics Of Gynodioecy In Silene Acaulis L. (Caryophyllaceae): Spatial Sex Structure And Inbreeding Depression, Stephen Robert Keller Dec 2002

The Ecological Genetics Of Gynodioecy In Silene Acaulis L. (Caryophyllaceae): Spatial Sex Structure And Inbreeding Depression, Stephen Robert Keller

Biological Sciences

Gynodioecy, the co-occurrence of females and hermaphrodites, is considered an intermediate step in the evolution of separate sexes in flowering plants. Highly variable female frequencies among populations suggest structuring of sex determining genes and differences in the relative fitness of females and hermaphrodites as seed parents. I investigated spatial variability in sex ratio and the effects of inbreeding on offspring quality in Silene acaulis. Female frequencies varied among populations from 0.32 to 0.69, and most were at temporal equilibrium. Females were significantly clumped within two of six populations. Females produced from 4 to 27 times as many fruits as hermaphrodites. …

Spawning Habitat Characteristics Of Pacific Herring (Clupea Pallasii) In Prince William Sound, Alaska, Brandee Lynn Gerke Dec 2002

Spawning Habitat Characteristics Of Pacific Herring (Clupea Pallasii) In Prince William Sound, Alaska, Brandee Lynn Gerke

Fisheries

Spawning habitats of Pacific herring in Prince William Sound, Alaska were analyzed to determine the importance of habitat features including vegetation type, percent vegetative cover, substrate type, water depth, and shoreline slope in the importance of herring spawning ground selection. Sidescan sonar data were used to compare bottom habitat characteristics of herring spawning areas vs. non-spawn areas. No significant differences in vegetation or substrate type were detected between areas where herring do and do not spawn. Generalized linear models and analysis of variance models were constructed to predict the probability of herring spawn and estimate egg densities given habitat information …

Growth, Foraging Behavior And Distribution Of Age-0 Arctic Grayling In An Alaskan Stream, Cheryl Ann Dion Dec 2002

Growth, Foraging Behavior And Distribution Of Age-0 Arctic Grayling In An Alaskan Stream, Cheryl Ann Dion

Fisheries

I evaluated the ability of three models to relate habitat characteristics to habitat quality for age-0 Arctic grayling Thymallullus arcticus in an Alaska stream. A temperature-based growth model made accurate predictions, showing it can reliably assess thermal habitat quality. Deviations between predicted and observed growth were useful because they identified the timing of possible critical periods, when competition for food or space may cause density-dependent mortality and emigration. A foraging model consistently overestimated the mean prey size of fish, showing that such models need further work before then can accurately assess food availability from invertebrate drift. A habitat selection model …

The Ecology Of Eulachon (Thaleichthys Pacificus) In Twentymile River, Alaska, Elizabeth Ann Spangler Dec 2002

The Ecology Of Eulachon (Thaleichthys Pacificus) In Twentymile River, Alaska, Elizabeth Ann Spangler

Fisheries

The ecology of eulachon (Thaleichthys pacificus) was studied at Twentymile River, a tributory of Turnagain Arm located in southcentral Alaska. In 2000 and 2001, we investigated the environmental factors associated with the migration of adult eulachon and downstream drift of larval eulachon. We assessed run timing, freshwater duration, length, weight, age, presence or absence of teeth, fecundity, and gear selectivity for dip and gill nets. Catch per unit effort of migrating adult fish were correlated with water temperature, tide height, river discharge, light intensity, and the density of bald eagles (Haliaeetus leucocephalus). Water temperature, river discharge, tide height, and light …

Microsatellite Variation Reveals Similar Population Genetic Structure For Two Species Of Rockfish (Sebastes Borealis And Sebastes Paucispinis) With Different Life Histories, Andrew Paul Matala Dec 2002

Microsatellite Variation Reveals Similar Population Genetic Structure For Two Species Of Rockfish (Sebastes Borealis And Sebastes Paucispinis) With Different Life Histories, Andrew Paul Matala

Fisheries

Rockfish belong to the speciose genus Sebastes (72 species described in the Northeast Pacific). Basic biological and life history information for many rockfish species is limited. Little is known about juvenile recruitment, and identification in early life stages is difficult because the larvae of congeners look similar and often occur in spatial and temporal association. Population genetic structure is an important element for characterization of species or populations, and may provide information on productivity and life history. Eight micro satellite loci were evaluated for variability in analyses of genetic structure for two species of rockfish: the deepwater shelf rockfish bocaccio …

Predicting Contaminant Transport Pathways In The Caribou-Poker Creek Research Watershed, Vincent Autier Dec 2002

Predicting Contaminant Transport Pathways In The Caribou-Poker Creek Research Watershed, Vincent Autier

Theses (Unassigned)

In order to evaluate the impact of natural organic matter (NOM) on drinking water, the hydrology of the Caribou-Poker Creeks Research Watershed (CPCRW) was considered. The CPCRW provided an excellent opportunity to investigate contaminant transport as it relates to hydrology in a well studied, discontinuous permafrost environment. The seasonal variation of organic chemistry of three different water sources (i.e. ground water, artesian spring and stream) was studied during the course of the year 2001. This thesis comprises three chapters, each of which seeks to gain a better understanding of the contaminant transport pathways in a boreal watershed, Caribou Poker Creeks …

Ice, Bedload Transport, And Channel Morphology On The Upper Kuparuk River, Jeffrey Albert Oatley Dec 2002

Ice, Bedload Transport, And Channel Morphology On The Upper Kuparuk River, Jeffrey Albert Oatley

Engineering

The objective of this study was to quantify the impact of bottom ice on sedimentation processes at a study site on the Upper Kuparuk River, in Northern Alaska. The approach taken was to use the Meyer-Peter and Mueller (1948) and Parker (1990) equations to determine bedload rating curves at four cross sections within the study reach, and to apply these rating curves to the ten year flow history of the study site to determine the total potential bedload transport that was suppressed during snowmelt runoff. In conjunction with this analysis, a tracer rock study was performed at the study site. …

Comparing The Nutritional Quality Of Steller Sea Lion (Eumetopias Jubatus) Diets, Monica Kaho Bando Dec 2002

Comparing The Nutritional Quality Of Steller Sea Lion (Eumetopias Jubatus) Diets, Monica Kaho Bando

Marine Biology

Though the primary cause(s) of the Steller sea lion decline remains unknown, one hypothesis is nutritional stress, possibly the result of climatic regime shifts reducing prey availability and/or quality. Researchers at the Alaska SeaLife Center formulated three feeding regimes representative of Steller sea lion diets: prior to and during their population decline and from a stable population. The purpose of this project was to compare the nutritional quality of these diets using proximate composition and bomb calorimetry. The pre-decline and stable diets are composed of more high-fat prey, like herring, with resulting energy densities being significantly higher than the decline …

Evidence For An Epigenetic Mechanism By Which Hsp90 Acts As A Capacitor For Morphological Evolution, Vincent E. Sollars, Xiangyi Lu, Li Xiao, Xiaoyan Wang, Mark D. Garfinkel, Douglas M. Ruden Dec 2002

Evidence For An Epigenetic Mechanism By Which Hsp90 Acts As A Capacitor For Morphological Evolution, Vincent E. Sollars, Xiangyi Lu, Li Xiao, Xiaoyan Wang, Mark D. Garfinkel, Douglas M. Ruden

Biochemistry and Microbiology

Morphological alterations have been shown to occur in Drosophila melanogaster when function of Hsp90 (heat shock 0-kDa protein 1α, encoded by Hsp83) is compromised during development1. Genetic selection maintains the altered phenotypes in subsequent generations1. Recent experiments have shown, however, that phenotypic variation still occurs in nearly isogenic recombinant inbred strains of Arabidopsis thaliana2. Using a sensitized isogenic D. melanogaster strain, iso-KrIf-1, we confirm this finding and present evidence supporting an epigenetic mechanism for Hsp90’s capacitor function, whereby reduced activity of Hsp90 induces a heritably altered chromatin state. The altered chromatin state is evidenced by ectopic expression …

Controlling Laser High-Order Harmonic Generation Using Weak Counter-Propagating Light, Sergei Leonidovich Voronov Dec 2002

Controlling Laser High-Order Harmonic Generation Using Weak Counter-Propagating Light, Sergei Leonidovich Voronov

Theses and Dissertations

Laser high-order harmonic generation in the presence of relatively weak interfering light is investigated. The interfering pulses intersect the primary harmonic-generating laser pulse at the laser focus. The interfering light creates a standing intensity and phase modulation on the field, which disrupts microscopic phase matching and shuts down local high harmonic production. Suppression of the 23rd harmonic (by two orders of magnitude) is observed when a counter-propagating interfering pulse of light is introduced. A sequence of counter-propagating pulses can be used to shut down harmonic production in out-of-phase zones of the generating volume to achieve quasi phase matching. Harmonic emission …

Feline Immunodeficiency Virus Integration In B-Cell Lymphoma Identifies A Candidate Tumor Suppressor Gene On Human Chromosome 15q151, Julia Beatty, Anne Terry, Julie Macdonald, Elizabeth Gault, Stanley Cevario, Stephen J. O'Brien, Ewan Cameron, James C. Neil Dec 2002

Feline Immunodeficiency Virus Integration In B-Cell Lymphoma Identifies A Candidate Tumor Suppressor Gene On Human Chromosome 15q151, Julia Beatty, Anne Terry, Julie Macdonald, Elizabeth Gault, Stanley Cevario, Stephen J. O'Brien, Ewan Cameron, James C. Neil

Biology Faculty Articles

Infection with immunosuppressive lentiviruses is associated with increased cancer risk,but most studies have implicated indirect mechanisms as the tumor cells generally lack integrated viral sequences.An exception wasfound in a B-cell lymphoma (Q254) where the tumor cells contained a single integrated feline immunodeficiency virus genome. Additional analysis now indicates that feline immunodeficiency virus integration in lymphoma Q254 resulted in promoter insertion and truncation of a conserved gene on feline chromosome B3, whereas the unaffected allele of the gene appeared to be transcriptionally down-regulated. The orthologous human gene (FLJ12973), is expressed ubiquitously and encodes a WD-repeat protein with structural similarity …
