In Silico Analysis Reveals The Role Of Horizontally Transferred Genes (Hgts) In Shaping The Pathogenicity Of Xanthomonas, Shrabanti Kundu, Asim Bothra, Louis S. Tisa, Arnab Sen

Molecular, Cellular & Biomedical Sciences

The role of Xanthomonas spp. as phytopathogen has been well recognized in diseases of important crops like rice, canola, tomato, citrus, etc. The genomes of a number of Xanthomonas strains are also fully sequenced and they are made available in various data bases. In the present study, in silico analysis of six Xanthomonas genomes was carried out. Synonymous codon usage pattern study in these genomes revealed that pathogenicity related (PR)-horizontally transferred genes (HGTs) were, in general, expressed lowly and were less biased in comparison with average protein coding genes and ribosomal protein genes. Moreover, the correspondence analysis showed that the …

The Role Of Landscape Connectivity In Planning And Implementing Conservation And Restoration Priorities. Issues In Ecology, Doborah Rudnick, Sadie J. Ryan, Paul Beier, Samual A. Cushman, Fred Dieffenbach, Clinton Epps, Leah R. Gerber, Joel N. Hartter, Jeff S. Jenness, Julia Kintsch, Adina M. Merenlender, Ryan M. Perkl, Damian V. Perziosi, Stephen C. Trombulack

Geography

Landscape connectivity, the extent to which a landscape facilitates the movements of organisms and their genes, faces critical threats from both fragmentation and habitat loss. Many conservation efforts focus on protecting and enhancing connectivity to offset the impacts of habitat loss and fragmentation on biodiversity conservation, and to increase the resilience of reserve networks to potential threats associated with climate change. Loss of connectivity can reduce the size and quality of available habitat, impede and disrupt movement (including dispersal) to new habitats, and affect seasonal migration patterns. These changes can lead, in turn, to detrimental effects for populations and species, …

Modular Autonomous Biosampler (Mab)- A Prototype System For Distinct Biological Size-Class Sampling And Preservation, Arthur Trembanis, Craig Cary, Val E. Schmidt, Don Clarke, Tristan Crees, Eric Jackson

Center for Coastal and Ocean Mapping

Presently, there is a community wide deficiency in our ability to collect and preserve multiple size-class biologic samples across a broad spectrum of oceanographic platforms (e.g. AUVs, ROVs, and Ocean Observing System Nodes). This is particularly surprising in comparison to the level of instrumentation that now exists for acquiring physical and geophysical data (e.g. side-scan sonar, current profiles etc.), from these same platforms. We present our effort to develop a low-cost, high sample capacity modular,autonomous biological sampling device (MAB). The unit is designed for filtering and preserving 3 distinct biological size-classes (including bacteria), and is deployable in any aquatic setting …

The Quantitative Soil Pit Method For Measuring Belowground Carbon And Nitrogen Stocks, Matthew A. Vadeboncoeur, Steven P. Hamburg, Joel D. Blum, Michael J. Pennino, Ruth D. Yanai, Chris E. Johnson

All Materials

Many important questions in ecosystem science require estimates of stocks of soil C and nutrients. Quantitative soil pits provide direct measurements of total soil mass and elemental content in depth-based samples representative of large volumes, bypassing potential errors associated with independently measuring soil bulk density, rock volume, and elemental concentrations. The method also allows relatively unbiased sampling of other belowground C and nutrient stocks, including roots, coarse organic fragments, and rocks. We present a comprehensive methodology for sampling these pools with quantitative pits and assess their accuracy, precision, effort, and sampling intensity as compared to other methods. At 14 forested …

Effects Of Incremental Dietary Levels Of Ground Flaxseed On Milk Production, Ruminal Metabolism, And Enteric Methane Emissions In Organic Dairy Cows, Katie Velez

Honors Theses and Capstones

Ground Flaxseed (Linum uitatissimum) is a lipid supplement that is commonly fed to dairy cows. It is believed that supplemental lipid can change the Fatty Acid (FA) composition in the milk, and decrease methane production. Twenty lactating organic Jersey cows, housed at the UNH Organic Dairy Research Farm (ODRF), were randomly assigned to five replicated 4 × 4 Latin squares to investigate the effects of increasing dietary levels of ground flaxseed (0, 5, 10, or 15% of the diet dry matter) on animal fperformance (e.g., dry matter intake, milk production, milk composition), ruminal metabolism, and enteric methane emissions. Each …

An Analysis Of The Incidence Of Antibiotic Resistant Infections In The State Of New Hampshire, Melanie Duhamel

Honors Theses and Capstones

The purpose of this research paper is to study, analyze, and characterize antibiotic resistance in both the theoretical and investigative contexts. After an in-depth examination of the literature and previous research investigating the definition, origin, affected organisms, and proposed coping mechanisms related to antibiotic resistance, a research plan was organized and executed.

The organism Methicillin Resistant Staphylococcus aureus (MRSA) was selected as the focus of study because of abundant current research and regulated monitoring of this organism in healthcare organizations. Data about the incidence rates of MRSA in theUnited States was collected from reports disseminated by the Center for Disease …

Variations In Carotenoids In Plasma From Jersey Cows At An Organic Dairy Compared To A Conventional Dairy Over Time, Jillian M. Smith

Honors Theses and Capstones

Interest in organic milk is increasing. By USDA Certified Organic standards, animals must be fed on pasture for a minimum of 120 days. Research indicates that various factors such as diet impact the nutritional quality and composition of milk. The objective of this study was to understand how feeding practices affected bovine plasma carotenoid concentrations over time. Plasma samples were collected from 9 cows fed on pasture at an organic dairy and from 9 cows fed total mixed ration (TMR) at a conventional dairy. Components were extracted from the plasma and separated via High Performance Liquid Chromatography. Results showed that …

One Can’T Stand On Its Own: Are Non-Luminescence Traits Necessary For V. Fischeri Colonization Of E. Scolopes?, Feier Liu

Honors Theses and Capstones

Vibrio fischeri and Euprymna scolopes squid establish mutualistic symbiosis and select for each other in the natural environment. V. fischeri provides bioluminescent camouflage for E. scolopes while E. scolopes provides nutrients for V. fischeri. The most intriguing aspect of this relationship is that E. scolopes is highly selective and only allows sustained colonization by luminous, but not dark V. fischeri. Luminescence is the key symbiosis trait; however, other bacterial factors may also allow squid recognition. We hypothesized that there are luminescence linked traits that contribute to colonization. V. fischeri with luminescence variation was isolated and tested for oxidative resistance, …

Eelgrass Distribution In The Great Bay Estuary For 2011, Frederick T. Short

PREP Reports & Publications

Eelgrass in the Great Bay Estuary declined in both distribution and biomass between 2010 and 2011. In 2011, eelgrass was once again mainly present in the Great Bay itself with limited distribution in Portsmouth Harbor and Little Bay. Eelgrass distribution in Great Bay itself decreased between 2010 and 2011 and experienced an alarming 26% loss of biomass in a single year. In Great Bay itself there has been a loss of 35% of eelgrass distribution since 1996. In 2011, despite recent consecutive excellent growing years in terms of weather, we saw a reverse of the trend of slight increases in …

Eelgrass Distribution In The Great Bay Estuary For 2010, Frederick T. Short

PREP Reports & Publications

The following is a revision of the 2010 eelgrass status report submitted to the Piscataqua Region Estuaries Partnership by Dr. Fred Short, correcting an error in eelgrass percent cover classification discovered by PREP staff during their QA/QC process. Eelgrass in the Great Bay Estuary in 2010 was once again mainly present in the Great Bay itself with limited distribution in Portsmouth Harbor. In 2010, Portsmouth Harbor experienced a 9% loss of eelgrass distribution since 2009, for a loss of 47% of the Harbor’s eelgrass distribution since 1996, an alarming trend. For the third year in a row in the Piscataqua …

Skeletal Muscle Volume Following Dehydration Induced By Exercise In Heat, Kyle J. Hackney, Summer B. Cook, Timothy J. Fairchild, Lori L. Ploutz-Snyder

Kinesiology

Background

Intracellular skeletal muscle water is redistributed into the extracellular compartment during periods of dehydration, suggesting an associated decline in muscle volume. The purpose of this study was to evaluate skeletal muscle volume in active (knee extensors (KE)) and less active (biceps/triceps brachii, deltoid) musculature following dehydration induced by exercise in heat.

Methods

Twelve participants (seven men, five women) cycled in the heat under two conditions: (1) dehydration (DHYD) resulting in 3% and 5% losses of estimated total body water (_ETBW), which was assessed by changes in body mass, and (2) fluid replacement (FR) where 3% and 5% …

Sequencing And Analysis Of The Gastrula Transcriptome Of The Brittle Star Ophiocoma Wendtii, Roy Vaughn, Nancy Garnhart, James R. Garey, W. Kelley Thomas, Brian T. Livingston

Hubbard Center for Genome Studies (HCGS)

Background

The gastrula stage represents the point in development at which the three primary germ layers diverge. At this point the gene regulatory networks that specify the germ layers are established and the genes that define the differentiated states of the tissues have begun to be activated. These networks have been well-characterized in sea urchins, but not in other echinoderms. Embryos of the brittle star Ophiocoma wendtii share a number of developmental features with sea urchin embryos, including the ingression of mesenchyme cells that give rise to an embryonic skeleton. Notable differences are that no micromeres are formed during cleavage …

Predicting Decadal Trends And Transient Responses Of Radiocarbon Storage And Fluxes In A Temperate Forest Soil, C. A. Sierra, S. E. Trumbore, E. A. Davidson, Serita D. Frey, K. E. Savage, F. M. Hopkins

Faculty Publications

Representing the response of soil carbon dynamics to global environmental change requires the incorporation of multiple tools in the development of predictive models. An important tool to construct and test models is the incorporation of bomb radiocarbon in soil organic matter during the past decades. In this manuscript, we combined radiocarbon data and a previously developed empirical model to explore decade-scale soil carbon dynamics in a temperate forest ecosystem at the Harvard Forest, Massachusetts, USA. We evaluated the contribution of different soil C fractions to both total soil CO2 efflux and microbially respired C. We tested the performance of the …
