Remote Sensing Observations Of Winter Phytoplankton Blooms Southwest Of The Luzon Strait In The South China Sea, Dan-Ling Tang, I-Hsun Ni, Dana R. Kester, Frank E. Muller-Karger

Marine Science Faculty Publications

The Luzon Strait is a channel between the Philippine Sea and the South China Sea. This area is traditionally classified as an oligotrophic zone with low primary productivity. Even so, high concentrations of pigment were detected 100 km southwest of the Strait through analysis of historical Coastal Zone Color Scanner (CZCS) data that the Nimbus-7 satellite collected during the winters of 1979 to 1986. These blooms were observed in December 1979, February 1983, February 1985, and January 1986, when sea surface temperatures measured with the National Oceanic and Atmospheric Administration's (NOAAs) Advanced Very High Resolution Radiometer (AVHRR) were 23 to …

Genetic Control Of Eye Development, A Case Study Focused On The Murine Mutation Belly Spot And Tail (Bst), Qing Tang

Theses and Dissertations (ETD)

Development of the eye is controlled by a network of genes, often conserved, that regulate the timing and location of cellular differentiation. One approach to understanding this network of genes and their interaction is to focus on mutations, spontaneous or induced, that predictably disrupt the proper function of such networks, and by examining the effect of such disruption on the function of other genes.

The Belly spot and tail (Bst) semi-dominant mutation, mapped to mouse Chromosome 16, leads to developmental defects of the eye, skeleton, and coat pigmentation. In the eye, the mutant phenotype is characterized by the presence of …

A Study Of The Seasonal Composition And Abundance Of Phytoplankton And Autotrophic Picoplankton In A Brackish Water Lake In Portsmouth Virginia, Jennifer Leigh Wolny

Biological Sciences Theses & Dissertations

The phytoplankton and autotrophic picoplankton populations of Hoffler Lake, a brackish-water lake in Portsmouth, Virginia, were monitored from May 1997 through May 1998, Analyses of the phytoplankton community using the Utennohl method showed a dominance of Chlorophytes (61-88% of the total abundance) throughout the year, including a winter bloom of Chlamydomonas snowii (maximum concentration of 2.5 x 101 cells/L). Subdominants were Cyanobacteria (10-33% of the total abundance) whose composition included several species of Anabaena, Lyngbya, and a fall bloom of Microcoleus sp. Diatoms, dinoflagellates, and cryptophytes played a secondary role in the phytoplankton community of Hoffler Lake. …

Reaction Of Arylsulfenyl Chloride Adducts Of Glycals With Vinyl Ethers., Mingming Han

Theses and Dissertations

This Ph.D. dissertation is focused on the stereoselective synthesis of β- C-glycosides. Such carbohydrate derivatives have been found to possess a wide spectrum of physiological activities. They can serve as non-hydrolizable enzyme inhibitors. C-Glycosides have been used as chiral precursors for synthesis of other compounds. The synthesis of β-C-glycosides is based on the fact that, in the presence of Lewis acids, ArSCl adducts of glycals can be converted to active intermediates, episulfonium ions. These intermediates are known to react with a number of C-nucleophiles. In this study, the reaction of ArSCl adducts of glycals with vinyl ethers was investigated. To …

Molecular Techniques Reveal Wide Phyletic Diversity Of Heterotrophic Microbes Associated With Discodermia Spp. (Porifera: Demospongiae), Jose V. Lopez, Peter J. Mccarthy, Kathleen E. Janda, Robin Willoughby, Shirley A. Pomponi

Marine & Environmental Sciences Faculty Articles

Sponges are well known to harbor large numbers of heterotrophic microbes within their mesohyl. Studies to determine the diversity of these associated microbes have been attempted for only a few shallow water species. We cultured various microorganisms from several species of Discodermia collected from deep water using the 'Johnson-Sea-Link' manned submersibles, and characterised them by standard microbiological identification methods. Characterisation of a small proportion (ca. 10%) of the total and potential eubacterial isolate collection with molecular systematics techniques revealed a wide diversity of microbes. Phylogenetic analyses of 32 small subunit (SSU) 16S-like rRNA gene sequences from different micorbes indicated high …

Professional Sports Teams And Fan Relations: A Public Relations Case Study Of The 1998-99 Philadelphia Eagles Football Team, Laura Elizabeth Litrenta

Theses and Dissertations

In professional sports, the field of public relations helps organizations foster positive relationships with their fans. But, when teams suffer losing seasons, recording more losses than wins, these relationships become strained.

The purpose of this study was to reveal how losing seasons affect the bond between professional sports teams and their fans. The results encourage sports relations practitioners to recognize fan needs and develop techniques that can help organizations maintain a more positive relationship with their fans during a losing season.

To examine the relationship between a professional sports team and its fans, this researcher traced the performance of the …

Species: Turning A Conundrum Into A Research Program, Daniel R. Brooks, Deborah A. Mclennan, E. C. Bernard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The most appropriate ontological basis for understanding the role of species in evolutionary biology is the Evolutionary Species Concept. The ESC is not an operational concept, but one version of the Phylogenetic Species Concept is. Linking the ontology of species with the epistemological basis of actual biological studies requires that we specify both a discovery mode for identifying collections of organisms that we believe are evolutionary species, and a series of evaluation criteria for assessing those entities we have discovered. Simply naming a collection of specimens, no matter how strong one’s evolutionary beliefs, is not sufficient for declaring that evolutionary …

An Interdisciplinary Approach To Integrated Curriculum, Lynda Kozicz Leahey

Theses and Dissertations

The purpose of this study was to explore the effectiveness of the interdisciplinary approach to teaching mathematics and science, specifically Geometry and Biology. The study used an action research design in which two teachers participated in a planned interdisciplinary activity that involved 160 high school students. The site of this study was a high school located in a middle-class, rural-suburban community. Data was gathered using a concept map to measure the amount of conceptual understanding students have of the relationship between Geometry and Biology. Data of those students who were enrolled in both Geometry and Biology were compared to those …

Effects Of Nicotine On Content Of Corticotropin Releasing Factor (Crf) In Rat Amygdala, Hypothalamus And Brain Stem, Sibonisiwe Ntini Masilela

Graduate Theses, Dissertations, and Problem Reports (ETD)

Effects of 1.0 mg/kg and 0.4 mg/kg intraperitoneal nicotine on hypothalamic and extra hypothalamic levels of corticotropin releasing factor (CRF) were examined in 104 rats. CRF, a 41-amino acid peptide involved in responses to stress, fear and anxiety, influences the same neurotransmitter systems as nicotine, a psychoactive component of tobacco. Radioimmunoassays revealed that in macro-dissected hypothalami, 15 minutes treatment with 1.0 mg/kg nicotine significantly increased CRF content compared to no treatment. The 1.0 mg/kg dose did not elicit effects in macro-dissected amygdala and brain stem. With 0.4 mg/kg nicotine, no significant effects were observed in micro-dissected hypothalamic paraventricular nucleus, amygdaloid …

Molecular Characterization Of Soil Ammonia-Oxidizing Bacteria Based On The Genes Encoding Ammonia Monooxygenase, Jose Javier Alzerreca

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ammonia-oxidizing bacteria (AOB) are chemolithotrophs that oxidize ammonia/ammonium to nitrite in a two-step process to obtain energy for survival. AOB are difficult to isolate from the environment and iso lated strains may not represent the diversity in soil. A genetic database and molecular tools were developed based on the ammonia monooxygenase (AMO) encoding genes that can be used to assess the diversity of AOB that exist in soil and aquatic environments without the isolation of pure cultures. The amo genes have excellent potential as molecular markers; since AMO is only found in the AOB and is essential for their metabolism, …

What Effect Will Increased Parental Involvement In Science/Biology At Woodrow Wilson High School Have On The Improvement Of Students Academically?, Lasandra Watkins

Theses and Dissertations

The purpose of this study was to discover whether or not student achievement could be improved through the increased participation of parents/guardians for students enrolled in science classes.

High academic achievement in science courses has been rapidly declining for the past twenty or more years. With this decline in science has come a decline in the overall academic achievement of students.

To turn the tide of students failing to students excelling academically in the sciences, I believe that increasing the level and quality of parental involvement is "the solution" to this problem.

Students in my biology classes will participate in …

Adult Attention Disorders: The Effect Of External Auditory Stimulation Of Attention And Comprehension During Reading, Angela M. Reining '99

Honors Projects

This study examined the underarousal/optimal stimulation theory of ADHD. This theory states that an optimal level of arousal is maintained through moderation of incoming sensory stimuli (Zentall & Zentall, 1983). It is proposed that some of the deviant behavior displayed by hyperactive children represents a functional set of responses to conditions of abnormal sensory input. Attempts to correct this imbalance in arousal through chemical and sensory stimulation have been relatively successful. A recent study supported this theory by demonstrating the positive effect of music on children doing arithmetic problems. Using college students with a tendency toward attention disorders, the present …

A Maritime Sense Of Place: Southeast Alaska Fishermen And Mainstream Nature Ideologies, Judith T. Brakel

Anthropology

This thesis portrays Southeast Alaska fishermen's 'senses of place' on the sea, elicited through interviews. The distinctiveness of a fishing culture, and the demands and opportunities of the occupation and environment, result in a relationship to place different from the majority society. Themes discussed include being at home on the sea, the environment as a basis for occupational choice, territorial flexibility, preference for wild nature, and wild nature produces exploitatable surpluses. The variability of the environment affects patterns of learning, models of nature, and values in inter-personal interactions. Relationship to 'place' is found to be central to the culture, but …
