Skewed Sex Ratio In An Estuarine Lobster (Homarus Americanus) Population, Winsor H. Watson Iii, William Hunting Howell

Jackson Estuarine Laboratory

A total of 19,485 lobsters were caught sites in the estuarine and coastal waters of New Hampshire from 1989 to 1992, and their size and sex were determined. The sex ratio of lobsters caught farthest from the coast, in Great Bay, was heavily skewed in favor in males. Sex ratios in other estuarine and river sites were also skewed toward males, and there was a tendency for the number of males per female to decline as one moved down the estuary toward the coast, where the sex ratio was nearly 1:1. The single offshore site was dominated by females, with …

A Limnological Assessment Of Russell Pond, Woodstock, New Hampshire, Michael Bailey, Tara Davignon

Center for Freshwater Biology

A limnological survey was conducted during 17-18 September, 1998 to characterize the trophic state of Russell Pond, a 15.8 Ha natural Lake located in Woodstock, Grafton County, New Hampshire. Physical, biological and chemical parameters were measured to assess the health of the lake and changes from previous studies. Russell Pond is oligotrophic with high Secchi disk depths (13.8 m), low phosphorus levels (3.8 µg L1) and low Chlorophyll a concentration (0.5 µg L-1). Peridinium (Dinophyceae) dominated (64%) the net phytoplankton. Calanoid copepods (Diaptomidae) constituted 87.5% of the crustacean zooplankton. The lake is at risk for acidification because of low acid …

The Effects Of Alewife (Alosa Pseudoharengus) On Zooplankton Community Structure In Depot Pond Nh And A Comparison Of Seven New Hampshire Lakes, S. R. Bradt, C. Chungu

Center for Freshwater Biology

Physical, chemical and biological features of seven New Hampshire lakes were examined in September and October of 1997. Zooplankton communities exhibited evidence of “top-down” control in Milton Three Ponds (Depot, Norteast, and Townhouse Ponds), showing effects of a planktivorous fish, Alosa pseudoharengus: small mean body size, dominance of small grazers such as Bosmina, and absence of large grazers such as Daphnia. Phosphorus concentrations were positively correlated to fluorescence of all water fractions, chlorophyll a and a phytoplankton biotic pollution index (modified from Hillsenhoff, 1978), revealing a level of “bottom-up” control.

Ecological And Population Changes In Fishing Communities Of The North Atlantic Arc, Lawrence C. Hamilton, Richard L. Haedrich

Sociology

In the decades since World War II, large-scale ecological changes have affected fishing communities across the northern Atlantic. Substantial declines hit their historically important resources, most notably the Atlantic cod. Such declines were often accompanied by increases in other, previously less exploited, species. Interactions between fishing pressure and environmental variation have driven ecological change. Ecological changes in turn reshaped the fisheries, contributing to altered demographic profiles of fisheries-dependent communities. Many places lost population, especially through out-migration of young adults. Broad social forces also contributed to these trends, but the timing and geographical details of population changes often correspond to specific …

Evolution Of Pycnogonid Life History Traits, Eric Carl Lovely

Doctoral Dissertations

The Pycnogonida is a class of arthropods with interesting life histories. Pycnogonids prey on hydroids and some invade hydranths while larvae. Males brood the eggs and larvae hatch as protonymphons. Questions relating to the evolution of life history characteristics were addressed. Evolutionary relationships were poorly understood. It was necessary to determine the relationships within the Pycnogonida and compared to other arthropods.

Twenty-four morphological characters were coded for twenty-three pycnogonid genera and one fossil ancestor, Palaeoisopus problematicus. A branch and bound analysis resulted in fifteen most parsimonious trees. The Nymphonidae were found to be basal. The Ammotheidae were paraphyletic and led …

The Effect Of Physical And Biological Site Characteristics On The Survival And Expansion Of Transplanted Eelgrass (Zostera Marina L), Ryan Clark Davis

Doctoral Dissertations

Eelgrass (Zostera marina L.) was transplanted at seven sites along the New Hampshire side of the Piscataqua River in 1993 and 1994. The eelgrass transplanting was one component of the New Hampshire Port Authority Mitigation Project, designed to mitigate for impacts to natural resources associated with the expansion of the port facility. Over 2.5 hectares of eelgrass were transplanted using a newly developed transplanting technique, the horizontal rhizome method, and ultimately created eelgrass habitat at several sites. However, transplants did not survive at any of the intertidal areas planted and were greatly reduced at several subtidal sites. The intertidal transplants …

The Long-Term Effects Of Disturbance On Nitrogen Cycling And Loss In The White Mountains, New Hampshire, Christine Lynn Goodale

Doctoral Dissertations

Theories of nitrogen retention suggest that N cycling and loss should increase with ecosystem successional age and with chronic N deposition over time (N saturation). These factors both affect northeastern U.S. forests, most of which receive elevated rates of N deposition and have experienced past disturbances by wind, logging, fire, or agriculture. This work examined the long-term (80--110 year) effects of land-use history on nitrogen cycling and loss in the White Mountains, New Hampshire. Historical land-use maps were used to identify a network of watersheds and plots containing burned, logged, or old-growth forests. Nitrate-N fluxes from old-growth watersheds exceeded those …

Ordinary Women: Government And Custom In The Lives Of New Hampshire Women, 1690-1770, Marcia Schmidt Blaine

Doctoral Dissertations

The prominence of patriarchy and common law has caused many historians to concentrate on the limitations placed on eighteenth-century Anglo-American women. The results often present women as objects, rather than subjects, of study. Using four major primary sources: Governor, Council and Assembly records, petitions, licensing materials, and treasury records, this study examines the relationship between ordinary women and the provincial government of New Hampshire in order to explain the customary options available to women in proceedings with the government. Even with a spouse still living, Anglo-American women acted as family agents and representatives when captured by the Native Americans and …

Effects Of Intralaminar Thalamic Nuclei, Prefrontal Cortical, And Hippocampal Lesions On A Seven-Choice Serial Reaction Time Task, Joshua Alan Burk

Doctoral Dissertations

Slow response speed has been associated with several neuropsychological disorders including Korsakoff's disease. The ability to respond to brief stimuli can be tested to assess whether slow response speed is due to slow stimulus processing. A seven choice serial reaction time task was developed to test the ability to respond to brief stimuli. Distractibility and stimulus discriminability were manipulated to challenge performance and cues were presented to enhance performance. In Experiment 1, six unlesioned rats were tested on this task. As expected, significant deficits were found when (1) stimulus duration was decreased, (2) bright distractor light was briefly presented, (3) …

Functional Characterization Of The Ccr4-Not Transcriptional Regulatory Complex, Vasudeo Badarinarayana

Doctoral Dissertations

The CCR4-NOT transcriptional regulatory complex affects expression of a number of genes both positively and negatively. This study demonstrates that the CCR4-NOT complex functionally and physically interacts with TBP and TAFs. Firstly, mutations in CCR4, NOT4, and NOT5 suppressed the his4-912 delta insertion by a mechanism similar to that observed for the defective TBP allele spt15-122. This mechanism appeared to involve stabilization of TBP binding to a specific non-consensus TATA sequence, CATAAA, in the his4-912 delta element. Secondly, using modified HIS3 promoter derivatives containing specific mutations within the TATA sequence, it was found that the NOT proteins were general repressors …

When Does Gender Matter? Explaining The Transition To Adulthood As A Gendered Process, Kimberly Autumn Mahaffy

Doctoral Dissertations

Most gender theory and research focuses on two points in the life course: childhood and middle adulthood. Less attention is given to the period in between. The purpose of this dissertation is to determine whether and how the transition to adulthood is gendered. To what extent do school, family, and labor market contexts have a different effect on adolescent girls and boys as they become adults?

Using data from the High School and Beyond 1980 Sophomore Cohort Study (1980--1992), 1 examine how social context differentially affects the plans for the future and adult status outcomes of young women and men. …

Isolation And Characterization Of A Caenorhabditis Elegans Src Loss-Of-Function Allele Using Reverse Genetics, Jennifer Dignan Hogan

Doctoral Dissertations

The vertebrate proto-oncogene Src is a protein-tyrosine kinase that has been implicated as a component of receptor-mediated signal transduction pathways important for cell growth and differentiation. Consistent with this notion, overexpression or activation of Src by mutation induces neoplastic transformation in cell culture, leads to tumorigenesis in laboratory animals, and has been observed in a number of human tumors. Despite years of intensive investigation, neither its role in oncogenesis nor its normal, biological role is understood.

To diminish the issue of redundancy that has complicated analysis of Src function in vertebrates and Drosophila, I have chosen to study Src function …

Behavioral And Physiological Responses Of The Lobster, Homarus Americanus, To Temperature: A New Synthesis, Steven Harold Jury

Doctoral Dissertations

Temperature has a pervasive influence on lobster behavior, physiology and ecology and affects their subsequent distribution in thermally variable habitats such as estuaries and coastal areas. A multidisciplinary approach, including field and laboratory studies, was used to show: (1) that lobsters sense temperature with warm and cool thresholds as small as 0.1--0.2°C; (2) the relationship between temperature and activity is not linear, but instead switches between a high activity level in warmer months (10--20°C) and a lower level in colder months (<10°C) with transition periods in the spring and fall; (3) Parallel studies in the lab and field show that daily levels of activity are not greatly influenced by small temperature variations (i.e. tidally induced changes of 14°C), but activity levels are significantly higher in the field (249 +/- 55.1 m/d) than in the laboratory (88 +/- 12.0 m/d); (4) lobsters prefer a narrow range of temperatures over others available in a thermal gradient and avoid temperatures >23.5 +/- 0.4°C, suggesting that they behaviorally thermoregulate. While this preferred temperature shifts seasonally, the final preferred temperature …

The Role Of Cytokines In The Pathogenesis Of Experimental Legionella Pneumophila Infections, Corinna Mary Krinos

Doctoral Dissertations

Legionnaires' disease is an acute lobar pneumonia caused, primarily by the facultative intracellular pathogen Legionella pneumophila. This organism when inhaled by humans descends into the lower respiratory tract and parasitizes alveolar macrophages. L. pneumophila adhered to U-937 cells, A549 cells and peritoneal macrophages from A/J mice in an opsonin-independent fashion. Following attachment, the organism penetrated the cell membrane, replicated within these cells eventually inducing lysis. To better define the adhesion of L. pneumophila to host cells, an E. coli clone (LP 116), expressing the 25 kDa major outer membrane protein (MOMP) of L. pneumophila was used in binding studies. This …

Preparation And Characterization Of Derivatized Microparticles Immobilized In Hydrogel Membranes For Optical Chemical Sensing Based On Polymer Swelling, Eric William Miele

Doctoral Dissertations

Hydrogel membranes containing aminated microparticles have been investigated for reflectance based optical sensing. The membranes were evaluated by UV/Vis spectrophotometry, for potential use in a remote distributive fiber optic chemical sensor. This work describes efforts for improving the signal and decreasing the overall response time of the membranes. The microparticles were prepared by dispersion and seeded emulsion polymerization techniques. The microparticles were derivatized to introduce pH sensitivity. The hydrogel membranes containing swellable microparticles are turbid. Scattering occurs at the microparticle-hydrogel interface and is based on refractive index changes accompanying polymer swelling. The particles swell in response to hydrogen ion concentration, …

Viability And Spatial Assessment Of Ecological Communities In The Northern Appalachian Ecoregion, Mark Gustav Anderson

Doctoral Dissertations

My objective was to design a conservation reserve system that included multiple viable examples of all ecological community types within one specific ecoregion---the Northern Appalachians. I developed and defined the boundaries of the ecoregion, constructed a comprehensive list of the ecological communities and determined their scale of occurrence and distribution patterns. I also assessed the types and distributions of biophysical features within the ecoregion and developed a hierarchical scheme to partition the region into biophysical subregions. Subsequently, I assessed 1500 occurrences of ecological communities in the region compiled from state Natural Heritage databases and an analysis of roadless areas. Each …

Motherwork, Artwork: The Mother/Artist In Fiction By Parton, Phelps, Chopin, Woolf, Drabble, And Walker, Nancy Hoyt Lecourt

Doctoral Dissertations

This study asks the question, What happens to a practicing (fictional) mother who also tries to be a practicing artist? How do literary texts represent such people? How do they represent the relationship between material and artistic work? The primary works studied are Sarah Parton's Ruth Hall, (1855), Elizabeth Stuart Phelps' The Story of Avis (1877), Kate Chopin's The Awakening (1899), Virginia Woolf's To the Lighthouse (1927), and Margaret Drabble's The Millstone (1965). The conclusion focuses on Alice Walker's short story, "Everyday Use."

Mother-artists finds themselves on the "wrong" side of the nature/culture binary, where ideologies about "true womanhood" and …

Atmospheric Transport And Deposition Of Water -Soluble Nitrogen To The Gulf Of Maine, Carolyn Estelle Jordan

Doctoral Dissertations

An intensive sampling program was carried out from May 1994 through November 1997 on the shore of the Gulf of Maine in New Castle, New Hampshire. Daily (24 hour averages) samples of bulk aerosol and gas phase HNO3, precipitation, and 20 aerosol size distributions were obtained. Particulate NH4+ and gas phase HNO3 were the dominant water-soluble nitrogen species in the atmosphere. Nitrate was the dominant inorganic nitrogen ion in precipitation.

These samples were used with 1000 hPa streamlines to classify sampled air masses according to their surface level transport and chemistry. Overall, mixed conditions occurred in 42% of the samples, …

The Chain Extension Of Beta-Keto Phosphonates And The Synthesis Of Polycyclopropanes, Christopher Andrew Verbicky

Doctoral Dissertations

A series of beta-keto phosphonates was prepared and their reactivity with the Furukawa-modified Simmons-Smith zinc carbenoid was studied. Various functionality was incorporated into these molecules in efforts to broaden the scope of the zinc-mediated chain extension reaction. The mechanism of the chain extension of dimethyl (2-oxopropyl)phosphonate was probed by nuclear magnetic resonance in efforts to observe key intermediates of these reactions.

The stereochemistry of bis-, tris-, and tetrakis-cyclopropanes was confirmed by a one directional asymmetric independent synthesis. Application of an olefin cross-metathesis reaction allowed vinyl tetrakis-cyclopropane to be elaborated into an advanced intermediate toward the preparation of FR-900848, a polycyclopropanated …

The Mut-2 Mutator Of Caenorhabditis Elegans, Kathrine Queta Flint Boese

Doctoral Dissertations

The mut-2 mutator plays multiple regulatory roles in the germ line of C. elegans. In addition to regulating germ line transposition of at least four distinct transposon families (Tc1, Tc3, Tc4 and Tc5) mut-2 is implicated in chromosome segregation. Animals that harbor the mut-2 mutator produce broods with a higher incidence of males phenotype (Him) as a result of an increase in X chromosome non-disjunction during meiosis.

Using the Him phenotype conferred by mut-2(r459), I mapped the gene to the dpy-14 sem-4 interval on LGI. However, efforts to identify a molecular clone of the gene were hampered because the available …

The Development Of Rna Probe And Rt-Pcr Assays For The Detection Of Enteroviruses In Sludge, Amy Elisabeth Moore

Doctoral Dissertations

Many wastewater treatment plants generate more sludge than can be disposed of by conventional means. The United States Environmental Protection Agency (USEPA) has encouraged communities to dispose of sludge by land application. Sludge may contain enteric viruses that are known to survive for long periods of time in sludge-amended soil and can travel great distances, potentially contaminating surface and ground water.

Standard cell culture methods for the detection of enteric viruses are costly and results are not obtained for 30 or more days. The development of methods that provide results more quickly and with lower cost are needed.

Controls On Spatial And Temporal Variability In Nitrous Oxide Fluxes Across A Tropical Rainforest Ecosystem In The Luquillo Experimental Forest, Puerto Rico, Claire Patricia Mcswiney

Doctoral Dissertations

Nitrous oxide (N2O) is a trace gas that contributes to the greenhouse effect and participates in the reactions that destroy stratospheric ozone. Soil microbial processes are significant producers of this trace gas, particularly in tropical areas, which are considered major sources in the global N2O budget. Nitrous oxide fluxes to the atmosphere are variable in space and time. In this study, spatial and temporal variability in surface N2O fluxes were assessed as well as the major environmental controls on N2O production for a tropical rainforest watershed in northeastern Puerto Rico. A static chamber technique was used to assess surface fluxes …
