Space Use And Habitat Affinities Of The Singing Vole On The Northern Foothills Of The Brooks Range, Alaska, Andrew Maguire

Master's Theses and Capstones

Arctic tundra is being affected by a rapidly warming climate, which is accompanied by shifts in plant community composition and structure. Shrub expansion, a predominant consequence of this warming, is linked with changes in nutrient cycling and has direct implications to global change biology. Habitats are being altered across the landscape, with subsequent changes to arctic faunal communities. While herbivory has been noted as important in contributing to plant community composition in the arctic, with the potential to both exacerbate and mitigate shifts toward shrub-dominated tundra landscapes, little research has been conducted on herbivore dynamics. Microtine rodents (i.e., voles and …

Parameterization Of Transient Storage And Nutrient Retention In Coastal New England Wetlands, Sophie Wilderotter

Master's Theses and Capstones

Wetlands may play an important role in the removal of nutrients from river networks. In order to better understand this process, field observations for eight wetland-dominated reaches in coastal Massachusetts and New Hampshire were parameterized for transient storage and nutrient uptake rate constants. Transient storage was observed in all study wetlands, but the amount of storage and how connected the storage areas were to the wetland channel were not easily related to wetland physical characteristics: including wetland length, wetland width, wetland area, sinuosity, and length-to-width ratios, depth of the off-channel area, width of the off-channel area, cross-sectional area of the …

Establishment Of The Multicolored Asian Lady Beetle, Harmonia Axyridis, As A Model System For The Evolution Of Phenotypic Variation, Lindsay Havens

Master's Theses and Capstones

The mechanisms behind the evolution and maintenance of striking visual phenotypes are as varied as the species that display these phenotypes. Multiple study systems have been well characterized and provide critical information about the evolution of these traits. However, new study systems in which the phenotype of interest can be easily manipulated and quantified are essential to answer many questions about the functionality of core evolutionary processes. One such model is elytral spot number of the multicolored Asian lady beetle, Harmonia axyridis (Chapter 1). I describe Harmonia axyridis as a potential novel model species for examining extreme phenotypic evolution. To …

Strengthening The Role Of Universities In Addressing Sustainability Challenges: The Mitchell Center For Sustainability Solutions As An Institutional Experiment, David D. Hart, Kathleen P. Bell, Laura A. Lindenfeld, Shaleen Jain, Teresa R. Johnson, Darren Ranco, Brain Mcgill

New Hampshire EPSCoR

As the magnitude, complexity, and urgency of many sustainability problems increase, there is a growing need for universities to contribute more effectively to problem solving. Drawing upon prior research on social-ecological systems, knowledge-action connections, and organizational innovation, we developed an integrated conceptual framework for strengthening the capacity of universities to help society understand and respond to a wide range of sustainability challenges. Based on experiences gained in creating the Senator George J. Mitchell Center for Sustainability Solutions (Mitchell Center), we tested this framework by evaluating the experiences of interdisciplinary research teams involved in place-based, solutions-oriented research projects at the scale …

Coordination And Sustainability Of River Observing Activities In The Arctic, James W. Mcclelland, Suzanne E. Tank, Robert G. M. Spencer, Alexander I. Shiklomanov

Faculty Publications

To understand and respond to changes in the world’s northern regions, we need a coordinated system of long-term Arctic observations. River networks naturally integrate across landscapes and link the terrestrial and ocean domains. Changes in river discharge reflect changes in the terrestrial water balance, whereas changes in water chemistry are linked to changes in biogeochemical processes and water flow paths. Sustained measurements of river water discharge and water chemistry are therefore essential components of an Arctic observing network. As we strive to establish and sustain long-term observations in the Arctic, these two measurements must be coupled. Although river discharge and …

Causes And Consequences Of Ecosystem Service Regionalization In A Coastal Suburban Watershed, Wilfred M. Wollheim, M. B. Green, B. A. Pellerin, Nathaniel B. Morse, Charles S. Hopkinson

Faculty Publications

The demand for ecosystem services and the ability of natural ecosystems to provide those services evolve over time as population, land use, and management practices change. Regionalization of ecosystem service activity, or the expansion of the area providing ecosystem services to a population, is a common response in densely populated coastal regions, with important consequences for watershed water and nitrogen (N) fluxes to the coastal zone. We link biophysical and historical information to explore the causes and consequences of change in ecosystem service activity—focusing on water provisioning and N regulation—from 1850 to 2010 in a coastal suburban watershed, the Ipswich …

Arctic Ocean Bathymetry: A Necessary Geospatial Framework, Martin Jakobsson, Larry A. Mayer, Dave Monahan

Center for Coastal and Ocean Mapping

Most ocean science relies on a geospatial infrastructure that is built from bathymetry data collected from ships underway, archived, and converted into maps and digital grids. Bathymetry, the depth of the seafloor, besides having vital importance to geology and navigation, is a fundamental element in studies of deep water circulation, tides, tsunami forecasting, upwelling, fishing resources, wave action, sediment transport, environmental change, and slope stability, as well as in site selection for platforms, cables, and pipelines, waste disposal, and mineral extraction. Recent developments in multibeam sonar mapping have so dramatically increased the resolution with which the seafloor can be portrayed …

Waste Water Treatment In New Hampshire: Analysis Of Nitrogen Treatment In The Great Bay Community, Jessica I. Kaczynski

Honors Theses and Capstones

This thesis addresses and analyzes the challenge of high nitrogen levels in treated wastewater. As fresh water supplies are decreasing, demand for water usage is increasing, as are pollution levels. Wastewater treatment plants are designed to improve the quality of wastewater and allow for future reuse. Although reusing wastewater was initially an innovative solution, many of the treatment plants that were built thirty years ago are now reaching the end of their useful life. This research focuses on the Great Bay community in New Hampshire and analyses the existing systems and accomplishments. Future projects are identified, as well as proposals …

Dementia And Primary-Care Health Measures:Hearing, Gait, And Markers Of Inflammation, Elsa Lindgren

Honors Theses and Capstones

Dementia is a syndrome associated with declining cognitive function that has a variety of types and causes, and is encountered frequently in general medical practice. Researchers are actively exploring possible risk factors for dementia. The St. Louis University Mental Status (SLUMS) exam is a dementia-screening exam used in primary care visits to detect cognitive impairment that may be a sign of dementia. This study compared scores on the SLUMS exam to other measures recorded in a typical primary care visit in 86 patients of age 65 and older to look for correlations between indicators of health, such as physical examination …

Effects Of Age, Density, And Seasonality On Molt Pattern In The Mammal Genus (Peromyscus), Rebecca Catherine Graves

Honors Theses and Capstones

Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes. Within and among years molt can vary by time and age or by reproductive status. Past studies have found differences in molt pattern and timing depending upon age, and between captive reared and wild caught individuals. There has been little investigation into the molting characteristics of Peromyscus leucopus and P. maniculatus, specifically in comparison to adults and juveniles. I used molt observed from museum specimens …

Toxic Cyanobacteria Aerosols: Tests Of Filters For Cells, Sean R. Perry, Alexis Mack, James F. Haney, Amanda Murby

Honors Theses and Capstones

Aerosolization of toxic cyanobacteria released from the surface of lakes is a new area of study that could uncover a previously unknown route of exposure to toxic cyanobacteria. Since toxic cyanobacteria may be responsible for adverse human health effects, methods and equipment need to be tested and established for monitoring these airborne bacteria. The primary focus of this study was to create controlled laboratory experiments that simulate natural lake aerosol production. I set out to test for the best type of filter to collect and analyze the aerosolized cells as small as 0.2-2.0 µm, known as picoplankton. To collect these …

Carnivore Diet Identification Through Scat And Genetic Analysis In Namibia, Africa, Alicia J. Walsh

Honors Theses and Capstones

Worldwide the cheetah population is declining making them Africa’s most endangered large cat. Namibia, Africa currently has the largest population of cheetahs in the world. During the summer of 2014, I did scat analysis of carnivores on the property of the Cheetah Conservation Fund (CCF) in Namibia in order to better understand the predators that compete with the cheetah and how the ecosystem works as a whole. I worked at CCF for nine weeks to analyze the diets of carnivores in the area through genetic and scat analysis. Analyzing carnivore feces would ultimately identify the diet of various carnivores in …

Gastrointestinal Nematodes Of Ovis Aries In Eastern Cape, South Africa And An Evaluation Of Current Anthelmintic Procedures, Melyssa Rowell

Honors Theses and Capstones

Humans have known about helminth infections since ancient times. Today half of the human population is plagued by a nematode infection. Nematodes are responsible for billions of dollars in global crop damage annually and have had devastating effects on the global livestock industry. Due to the lack of a vaccine, and only a handful of approved classes of anthelmintics, nematode resistance has become a serious global phenomenon, and the South African commercial sheep industry has been one of the worst affected worldwide. The current study used fecal float parasitology to determine the nematode species found on a commercial sheep farm …

Fungicide Resistance Genetics Of Apple Scab Fungus Venturia Inaequalis, Alexis Lt Reddel

Honors Theses and Capstones

Apple scab, caused by the ascomycete fungus Venturia inaequalis, is considered the most devastating disease on domestic apple crops. Apples are the most important cultivated crop in temperate regions and the United States produced about 4.6 million tons of apples in 2010. Traditional methods to control fungal plant diseases like apple scab are based on the use of chemical compounds that may produce serious negative effects, mainly related with environmental pollution and the development of fungicide resistance. Identifying genes and mechanisms of fungicide resistance in V. inaequalis is imperative to developing new and more effective defenses against the spread …

Authenticity In Constructivist Inquiry: Assessing An Elusive Construct, Patrick Shannon, Elyse Hambacher

Education

Methodological rigor in constructivist inquiry is established through an assessment of trustworthiness and authenticity. Trustworthiness parallels the positivistic concepts of internal and external validity, focusing on an assessment of the inquiry process. Authenticity, however, is unique to constructivist inquiry and has no parallel in the positivistic paradigm. Authenticity involves an assessment of the meaningfulness and usefulness of interactive inquiry processes and social change that results from these processes. However, the techniques for ascertaining authenticity are in the early stages of development. Therefore, the purpose of this article is to describe a process for assessing authenticity in a constructivist inquiry. A …

Satellite Evidence For Significant Biophysical Consequences Of The “Grain For Green” Program On The Loess Plateau In China, Jingfeng Xiao

All Materials

Afforestation has been implemented worldwide as regional and national policies to address environmental problems and to improve ecosystem services. China's central government launched the “Grain for Green” Program (GGP) in 1999 to increase forest cover and to control soil erosion by converting agricultural lands on steep slopes to forests and grasslands. Here a variety of satellite data products from the Moderate Resolution Imaging Spectroradiometer were used to assess the biophysical consequences of the GGP for the Loess Plateau, the pilot region of the program. The average tree cover of the plateau substantially increased because of the GGP, with a relative …

The Ins And Outs Of Metal Homeostasis By The Root Nodule Actinobacterium Frankia, Teal R. Furnholm, Louis S. Tisa

New Hampshire Agricultural Experiment Station Publications

Background: Frankia are actinobacteria that form a symbiotic nitrogen-fixing association with actinorhizal plants, and play a significant role in actinorhizal plant colonization of metal contaminated areas. Many Frankia strains are known to be resistant to several toxic metals and metalloids including Pb2+, Al+3, SeO2, Cu2+, AsO4, and Zn2+. With the availability of eight Frankia genome databases, comparative genomics approaches employing phylogeny, amino acid composition analysis, and synteny were used to identify metal homeostasis mechanisms in eight Frankia strains. Characterized genes from the literature and a meta-analysis of 18 heavy metal gene microarray studies were used for comparison.

Results: Unlike most …
