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. …

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 …

Synthetic And Computational Studies On Polycyclic Aromatic Hydrocarbon Derivatives, Nucleoside Analogs And Peptides, Felix Nyuangem Ngassa

Theses and Dissertations

In recent years, the understanding of the structure and functions of biological macromolecules has advanced rapidly, the result of which is a better mechanistic understanding of many biological processes. As an outgrowth of this understanding, organic molecules that react with biological macromolecules (DNA) or adopt conformations responsible for specific functions in biological macromolecules (peptides and proteins) have been synthesized and computational modeling studies performed. Polycyclic aromatic hydrocarbons (PAHs) and β-peptides are among synthetic organic compounds known to interact with natural biological macromolecules. This interaction may affect the specific biological functions of the biomacromolecules. A variety of synthetic methodologies have been …

Variation And Systematics Of The Malayan Snail-Eating Turtle, Malayemys Subtrijuga (Schlegel And Müller, 1844), Timothy R. Brophy

Faculty Dissertations

Allometry, sexual dimorphism, and geographic variation were studied in the Malayan snail-eating turtle, Malayemys subtrijuga (Schlegel and Müller, 1844), using regression and discriminant function analyses. Allometry was evident in M. subtrijuga from the Chao Phraya River Basin. Shell shape changed in males as carapace length increased more than shell width and height, whereas females showed proportional changes. This difference in allometric growth yielded sexually dimorphic adults. Females attained larger sizes and had relatively wider and higher shells than males. Discriminant function analysis of shell and head-stripe characters revealed a clear pattern of geographic variation that was consistent with the topography …

Diets Of Baird’S Beaked Whales, Berardius Bairdii, In The Southern Sea Of Okhotsk And Off The Pacific Coast Of Honshu, Japan, William A. Walker, James G. Mead, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Stomach contents were analyzed from 127 Baird’s beaked whales, Berardizls bairdii, taken in coastal waters of Japan. During late July-August of 1985- 1987, 1989, and 1991, 107 samples were collected from off the Pacific coast of Honshu. An additional 20 samples were collected from whales taken in the southern Sea of Okhotsk during late August-September of 1988 and 1989. Prey identification using fish otoliths and cephalopod beaks revealed the whales fed primarily on deep-water gadiform fishes and cephalopods in both regions. Prey species diversity and the percentage of cephalopods and fish differed between the two regions. Off the Pacific …

Survey Attitudes Toward Stem Cell Research, Ejinkonye C. Anekwe

Theses and Dissertations

In the following research study, a self-administered questionnaire was utilized to assess opinions regarding embryonic stem cell research based on three objectives: willingness to accept stem cells, educational background, and religion. A total of 1 13 fixed-alternative questionnaires were distributed to a diverse group of respondents. Nonprobability sampling using the accidental approach was performed. Support of stem cell research was dependent on Question 9, which asked what people thought about the cloning of human embryonic stem cells. The data revealed that most respondents from all groups surveyed opposed stem cell research. Neither education nor religion was a major determinant in …

The Mount Feather Diamicton Of The Sirius Group: An Accumulation Of Indicators Of Neogene Antarctic Glacial And Climatic History, G. A. Wilson, J. A. Barron, A. C. Ashworth, R. A. Askin, J. A.

Department of Earth and Atmospheric Sciences: Faculty Publications

A paucity of data from the Antarctic continent has resulted in conflicting interpretations of Neogene Antarctic glacial history. Much of the debate centres on interpretations of the glacigene Sirius Group strata that crop out as discrete deposits along the length of the Transantarctic Mountains and in particular on its age and the origin of the siliceous microfossils it encloses. Pliocene marine diatoms enclosed within Sirius Group strata are inferred to indicate a dynamic East Antarctic ice sheet that was much reduced, compared with today, in the early-middle Pliocene and then expanded again in the late Pliocene. However, the geomorphology of …

Madonnas And Whores: The Dichotomy Of Women's Roles As Portrayed In Women's Magazine Advertisements, Karen Celeste Kimbell

Theses & Dissertations

Advertising has played a vital role in the increase of the number and circulation of magazines. Women's magazines, in particular, are saturated with ads to the point where often the copy text and the advertisements are indistinguishable. Early in the history of women's magazines, advertisements focused on women's domestic role as mother and wife, offering products to improve the home and help with caring for the family. Soon, products for beauty enhancement began showing up in advertisements as well, and beauty products continue to be heavily marketed in women's magazines. With the women's sexual revolution, the notion of beauty changed …

Binge Eating Disorder And Its Relationship To Bulimia Nervosa And Obesity, Lara Schultz Lacaille

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent research indicates that 2% to 4% of the population meet diagnostic criteria for the newly proposed binge eating disorder, and that it is much more common (30%) among the treatment-seeking obese. Although recognized as a significant problem, binge eating disorder is l1l not well understood, and there is debate about whether binge eating disorder is a distinct disorder. It has been argued that binge eating disorder is simply a variant or milder form of bulimia nervosa and not a separate and distinct disorder. Researchers have begun to study this population in greater depth in order to assess the characteristics …

Function And Size Optimization In Mucuna Urens Vexillum, May 2002, Mark Macedo

Monteverde Institute: Tropical Ecology and Conservation

This study examines the role of the vexillum as an aural nectar guide in the species Mucuna urens. Field manipulations show that the vexillum of M. urens enhances visitation and pollen removal (X2 = 52.8, p<.001). Subsequent observational studies conducted on bat visited hummingbird feeders support this finding as well (X2 = 10.67, p< .005). Data also show an increase in vexillum size correlated with number of bats visits (X2 = 32.06, p < .001). Two explanations are offered for why M. urens and other bat pollinated flowers in the genus have not developed as large a vexillum as possible. Investment return optimization is one possible explanation. Niche partitioning of potential pollinators is another.

Physiological Importance Of 1,25(Oh)2D3 Membrane-Initiated And Nuclear Actions In Chickens As A Function Of Growth, And Maturation In Male And Female Chickens, Birgitta Larsson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is well established that l,25(OH)₂D₃ is a major regulator of calcium homeostasis. The steroid exerts its effects on its target organs by two mechanisms, a slow mechanism mediated by nuclear vitamin D receptors (nVDR), and a rapid mechanism mediated by the l,25(OH)₂D₃ membrane-associated rapid response steroid binding protein (l,25D₃-MARRS bp). In this dissertation, the physiological relevance of membrane initiated steroid signaling was investigated by studying the correlation of age in male and female chickens with the magnitude of responses to l,25(OH)₂D₃ in duodena from 7-, 14-, 28-, and …

Design And Implementation Of Web-Based Gis For Forest Fragmentation Analysis, Fei Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

The advantages and limitations of current web GIS software for forest fragmentation information and analysis functionality were investigated using Landsat Thematic Mapper data of 1987 to 1999 for a test site in northern West Virginia. ESRI's ArcIMS technology was used to build a Web-based forest fragmentation analysis system to query, represent, and analyze the status of forest fragmentation using landscape metrics. Both ArcIMS HTML and Java fragmentation analysis tools were constructed. The web GIS was evaluated with respect to accessibility, navigation, interactive cartographic functionality, and spatial analysis functionality. The current ArcIMS approach was found to offer only limited support for …
