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 …

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 …

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 …

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 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. …

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 …

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 …

Communication Apprehension: A Narrative Analysis Of The Prca-24, Karri C. Vandeventer Dec 2002

Communication Apprehension: A Narrative Analysis Of The Prca-24, Karri C. Vandeventer

Communication

This exploratory study examined individuals' lived experience with communication apprehension (CA). CA has been explored extensively over the past 35 years by researchers seeking psychological explanations for communication phenomenon and employing the premise that CA exists as a "trait-like" characteristic of personality or as a relatively permanent behavioral disposition. Grounded in a constructionist epistemology, this study presumes that meaning is created, maintained, and transformed through communication with others. From this perspective, CA is an individual's evaluation of anticipated or occurring communication events, based upon his/her prior experiences interacting with others in specific situations. Though CA researchers acknowledge this situational basis …

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. …

Preliminary Studies Of A Measure Of Conscientiousness, Braddon M. Garner Ma Dec 2002

Preliminary Studies Of A Measure Of Conscientiousness, Braddon M. Garner Ma

Doctor of Psychology (PsyD)

Psychologists have been interested in personality characteristics for decades. One characteristic of personality studied by researchers is that of conscientiousness. Conscientiousness can de defined as a "degree of organization, persistence, and motivation in goal-directed behavior" (Costa & McCrae, 1985, p.2) This study divided the terms defining conscientiousness into three categories for purpose of item development: organization, persistence, and motivation. Organization incudes, but is not limited to, being organized, reliable, and practical. Persistence includes concepts of responsibleness, thoroughness, and commitment to hard-work. Motivation involves characteristics of enthusiasm, morality, cautiousness, and seriousness. The purpose of this study was to develop a measure …

Fast Convergence Control Approach For High Dimensional Chaotic Systems, Hsun-Heng Tsai, Chyun-Chau Fuh, Pi-Cheng Tung Dec 2002

Fast Convergence Control Approach For High Dimensional Chaotic Systems, Hsun-Heng Tsai, Chyun-Chau Fuh, Pi-Cheng Tung

Journal of Marine Science and Technology–Taiwan

A simple and efficient method for controlling high dimensional discrete-time chaotic systems is proposed in this paper. This method is implemented similar to the OGY method, and is feasible for practical experiments. The key component is to assign the eigenvalues of a linearized map by using the well-known pole placement technique. According to the Cayley-Hamilton theorem, the trajectory will converge to the desired fixed point after n iterations at most (n is the dimension of the map), if the real trajectory of the chaotic system falls within the neighborhood of the desired fixed point. The proposed approach improves the convergence …

Atmospheric Transmittance Of Amsu Channels: A Fast Computation Model, Tsung-Hua Kuo, Gin-Rong Liu, Chen-Gen Huang, Tang-Huang Lin, Chung-Chih Liu

Journal of Marine Science and Technology–Taiwan

In this study, the atmospheric transmittance of individual NOAA AMSU microwave channels was computed into a 40-layer atmospheric line-by-line FASCODE radiation model. Long-term sounding data from 1956 to 1991 collected over the Taiwan area was used to construct a 40-layer standard atmospheric model for the island. The simulated transmittance was also used to establish a regression-based fast-algorithm model to compute the atmospheric transmittance of Taiwan and its surrounding areas for various purposes. Despite the fact that the lower atmospheric layers of channels 14-18 indicated larger errors, the overall results revealed that the absolute value difference between the AMSU pass band-averaged …
