Reef Structure Alternatives For Restoration Of Oyster (Crassostrea Virginica) Populations In New Hampshire, Raymond E. Grizzle, David M. Burdick, Jennifer Greene, Holly Abeels, Mark Capone

PREP Reports & Publications

Eastern oyster (Crassostrea virginica) populations in New Hampshire have experienced severe declines since the 1990s, and restoration of oyster populations has been a major goal for New Hampshire management agencies. The most widely used technique in recent years in New Hampshire has been "spat seeding" which involves setting larvae from disease-resistant and/or fast-growth broodstock onto cultch material in large shore-based tanks, then distributing the spat attached to cultch onto the bottom to initiate reef restoration. This approach has the dual potential of providing direct population enhancement as well as introduction to the local gene pool of disease-resistance and/or fast-growth potential. …

Extensions To Gene Set Enrichment, Zhen Jiang, Robert Gentleman

Bioconductor Project Working Papers

Motivation: Gene Set Enrichment Analysis (GSEA) has been developed recently to capture moderate but coordinated changes in the expression of sets of functionally related genes. We propose number of extensions to GSEA, which uses different statistics to describe the association between genes and phenotype of interest. We make use of dimension reduction procedures, such as principle component analysis to identify gene sets containing coordinated genes. We also address the problem of overlapping among gene sets in this paper.

Results: We applied our methods to the data come from a clinical trial in acute lymphoblastic leukemia (ALL) [1]. We identified interesting …

Contributions Of Muscle Fatigue To A Neuromuscular Neck Injury In Female Standard Ballroom Dancers, Teri Riding

Theses and Dissertations

Objective: To investigate the potential etiology of a loss of neck control injury in female standard ballroom dancers. The median frequency (MF) as measured by electromyography (EMG) of the left upper trapezius (UT), left splenius capitius (SPL), and right sternocleidomastoid (SCM) of injured dancers was compared to non-injured dancers. This comparison was performed to identify whether dancers with a history of loss of neck control have a greater amount of fatigue than those with no history of this particular injury. Design and Setting: A 2 x 6 factorial design was used for this investigation. The independent variables were group (injured …

Research On Synthetic Rope And Its Future In Timber Harvesting, Joel N. Hartter, Jared Leonard, John Garland, Steve Pilkerton

Geography

Steel wire rope is used for many logging applications. It has served the industry well in terms of strength, durability, and longevity. However, steel wire rope is difficult to use because it is stiff, heavy, and unyielding. These characteristics can lead to fatigue and exhaustion, and may contribute to worker injuries. Ultra-high molecular weight polyethylene synthetic rope has the potential to replace steel wire rope for selected logging applications. Research shows ergonomic gains and other operational effectiveness with its use. This paper presents research results, potentials, and issues in improving economic and ergonomic performance of ground-based and cable logging. Potential …

Agroforestry: Sustaining Native Bee Habitat For Crop Pollination, Mace Vaughan, Scott Hoffman Black

Agroforestry Notes (USDA-NAC)

Over one hundred crop species in North America require a visit from an insect pollinator to be most productive. In the past, native bees and feral honey bees could meet the pollination needs of small orchards, tomato and pumpkin fields, and berry patches, because these farms were typically adjacent to areas of habitat that harbored important pollinators. Today, many farms are large and, at the same time, have less nearby habitat to support native pollinators. To ensure adequate pollination services, producers now rely on European honey bees. Research, however, shows that native bees can be important pollinators in agricultural fields …

Population Divergence In Plasticity Of The Avt System And Its Association With Aggressive Behaviors In A Death Valley Pupfish, Sean C. Lema

Biological Sciences

Behavioral differences can evolve rapidly in allopatry, but little is known about the neural bases of such changes. Allopatric populations of Amargosa pupfish (Cyprinodon nevadensis) vary in aggression and courtship behaviors in the wild. Two of these wild populations were recently found to differ in brain expression of arginine vasotocin (AVT)—a peptide hormone shown previously to modulate aggression in pupfish. These populations have been isolated for less than 4000 years, so it remained unclear whether the differences in behavior and neural AVT phenotype were evolved changes or plastic responses to ecologically dissimilar habitats. Here, I tested whether these …

The Effects Of Dispersal And Recruitment Limitation On Community Structure Of Odonates In Artificial Ponds, Shannon J. Mccauley

Biological Sciences

I examined the effects of isolation on the structure of both adult and larval dragonfly (Odonata: Anisoptera) communities forming at physically identical artificial ponds over two years. Isolation, whether measured by distance to the nearest source habitat or by connectivity to multiple sources, was significantly negatively related to the species richness of dragonflies observed at and collected in these ponds. These results indicate that dispersal and recruitment limitation acted as filters on the richness of communities at these artificial ponds. The richness of larval recruits in artificial ponds was lower than the richness of adult dispersers observed at ponds, and …

Modulation Of Intraoral Subambient Pressure And Feeding Behavior Relative To Prey Type In The Largemouth Bass, Micropterus Salmoides Floridanus, Sarah Legates

Masters Theses & Specialist Projects

Variation, or modulation, of suction feeding performance across two prey location treatments, as measured by peak subambient pressure generation, was studied in the Florida largemouth bass, Micropterus salmoides floridanus. Previous studies of suction feeding in centrarchids have excluded possible sources of performance variation to minimize the modulatory response. Florida bass are known to modulate their feeding kinematics when exposed to prey at different levels of elusiveness, and were in turn predicted to vary suction pressure generation when exposed to these conditions. Eight bass fed Palaemonetes sp. shrimp in an open water (elusive) setting and in a vegetated (non-elusive) setting were …

The Effects Of Avian Influenza Outbreak On U.S. Poultry Prices, Shang-Ho Yang

Masters Theses & Specialist Projects

Even in the absence of proven human-to-human transmission of the disease, the uncertainty surrounding bird flu could devastate regional economic growth and financial markets. Confirmed cases of human infection from several subtypes of avian influenza infection have been reported since 1997. According to WHO (World Health Organization), experts indicate that there is a possible risk of infection to people who have contact with infected birds or surfaces that have been contaminated with secretions or excretions from infected birds during an outbreak of avian influenza among poultry. On May 8, 2006, WHO reported on 207 cases that resulted in 115 people's …

Ordinality And Inferential Abilities Of A Grey Parrot (Psittacus Erithacus), Irene M. Pepperberg

Sentience Collection

A grey parrot (Psittacus erithacus), able to label the color of the bigger or smaller object in a pair (I. M. Pepperberg & M. V. Brezinsky, 1991), to vocally quantify ≤6 item sets (including heterogeneous subsets; I. M. Pepperberg, 1994), and separately trained to identify Arabic numerals 1–6 with the same vocal English labels but not to associate Arabic numbers with their relevant physical quantities, was shown pairs of Arabic numbers or an Arabic numeral and a set of objects and was asked for the color of the bigger or smaller one. The parrot’s success showed he (a) understood number …

Cell Edge Features Affected By Microtubule Inhibitor Combinations, Sonal Uppal, Nancy Boudreau, Elizabeth Wendt, Carol Heckman

Applied Statistics and Operations Research Faculty Publications

The tumor promoter, phorbol 12-myristate 13-acetate (PMA), enhances tumor yield through an epigenetic mechanism. PMA, like another promoter, phosphatase inhibitor okadaic acid, works by maintaining proteins in a phosphorylated state. In order to identify chemicals with promoter and antipromoter effects, this laboratory has developed a standard curve of morphogenetic changes using data from precancerous cell lines that eventually became neoplastic. Using the curve as a basis of comparison, we defined the “signature” phenotype as that adopted when a cell line became neoplastic. The results of solving for signature type disclosed that the microtubule-depolymerizing compound, colchicine, had a promoter-like effect [2]. …

Analysis Of Treatment Effects On The Microbial Ecology Of The Human Intestine, Anna L. Engelbrektson, Joshua R. Korzenik, Mary Ellen Sanders, Brian G. Clement, Gregory Leyer, Todd R. Klaenhammer, Christopher L. Kitts

Biological Sciences

A large number of studies have investigated gastrointestinal microbiota and changes in the gastrointestinal community. However, a concern in these studies is how best to assess changes in gastrointestinal community structure. This paper presents two different human trials where the fecal terminal restriction fragment length polymorphism data sets were analyzed to search for treatment effects. Principle components analysis and cluster analysis based on grouped data are compared with analysis of data by subject using distance coefficients. Comparison with baseline within an individual before grouping by treatment provided a clearer indication of treatment effects than did an evaluation of data grouped …

The Effect Of Varying Cadence In Cycle Ergometry On Submaximal Predictions Of Peak Oxygen Uptake, Zachary Callahan

Masters Theses & Specialist Projects

The purpose of this study was to investigate the effect that varying cadence had on the ability of a submaximal cycle ergometry test to accurately predict peak oxygen uptake (VO2) using the standard YMCA protocol workloads. There has been limited scholarship investigating the effect that varying cadence has on trained cyclists and almost none on untrained participants. For this study twelve moderately healthy participants (age: 20.75 ± 1.87, body fat: 15.8 ± 4.91 %) who did not use cycling as part of their workout regime performed a peak VO2 cycle test and three randomized submaximal tests. The three submaximal tests …

Strategies For Reducing Mosquito-Borne Disease Vulnerability In Equine Populations: A Kentucky Case Study, Sara Dalton

Masters Theses & Specialist Projects

This research examined equine management practices that limit or contribute to the spread of West Nile virus and other mosquito-bome disease. I hypothesize that there is a relationship between equine management practices and outbreaks of mosquito-borne disease in horse populations. Improved and appropriate mosquito habitat management may limit the risk of mosquito-borne disease in humans and horses by helping to lower the mosquito populations. The study goals were to recognize equine management practices and mosquito prevention practices that foster outbreaks of mosquito-borne disease. This study used a questionnaire for county level analysis of equine management practices and the relationship to …

Molecular Population Genetics And Phenotypic Diversification Of Two Populations Of The Thermophilic Cyanobacterium Mastigocladus Laminosus, Scott R. Miller, Michael D. Purugganan, Stephanie E. Curtis

Biological Sciences Faculty Publications

We investigated the distributions of genetic and phenotypic variation for two Yellowstone National Park populations of the heterocyst-forming cyanobacterium Mastigocladus (Fischerella) laminosus that exhibit dramatic phenotypic differences as a result of environmental differences in nitrogen availability. One population develops heterocysts and fixes nitrogen in situ in response to a deficiency of combined nitrogen in its environment, whereas the other population does neither due to the availability of a preferred nitrogen source. Slowly evolving molecular markers, including the 16S rRNA gene and the downstream internal transcribed spacer, are identical among all laboratory isolates from both populations but belie considerable genetic and …

Role Of The Stable Signal Peptide Of Junín Arenavirus Envelope Glycoprotein In Ph-Dependent Membrane Fusion, Joanne York, Jack H. Nunberg

Biological Sciences Faculty Publications

The envelope glycoprotein of the arenaviruses (GP-C) is unusual in that the mature complex retains the cleaved, 58-amino-acid signal peptide. Association of this stable signal peptide (SSP) has been shown to be essential for intracellular trafficking and proteolytic maturation of the GP-C complex. We identify here a specific and previously unrecognized role of SSP in pH-dependent membrane fusion. Amino acid substitutions that alter the positive charge at lysine K33 in SSP affect the ability of GP-C to mediate cell-cell fusion and the threshold pH at which membrane fusion is triggered. Based on the presumed location of K33 at or near …
