Habitat Selection By Female Swift Foxes (Vulpes Velox) During The Pup- Rearing Season, Indrani Sasmal, Jonathan A. Jenks, Troy W. Grovenburg, Shubham Datta, Greg. M. Schroeder, Robert W. Klaver, Kevin M. Honness

The Prairie Naturalist

The swift fox (Vulpes velox) was historically distributed in western South Dakota including the region surrounding Badlands National Park (BNP). The species declined during the mid-1800s, largely due to habitat loss and poisoning targeted at wolves (Canis lupis) and coyotes (C. latrans). Only a small population of swift foxes near Ardmore, South Dakota persisted. In 2003, an introduction program was initiated at BNP with swift foxes translocated from Colorado and Wyoming. We report on habitat use by female swift foxes during the pup-rearing season (May–July) in 2009. Analyses of location data from 13 radiomarked female foxes indicated disproportional use (P < 0.001) of some habitats relative to their availability within swift fox home ranges. Swift foxes used grassland (ŵ = 1.01), sparse vegetation (ŵ = 1.43) and prairie dog towns (ŵ = 1.18) in proportion to their availability, whereas they were less likely to use woodland (ŵ = 0.00), shrubland (ŵ = 0.14), pasture/agricultural-land (ŵ = 0.25) and development (ŵ = 0.16) relative to availability. Swift foxes typically are located in habitats that provide greater visibility, such as shortgrass prairie and areas with sparse vegetation; which allow detection of approaching coyotes (e.g., primary predator of swift foxes).

Distribution Of Crayfish Species In Select North Dakota Streams, Cari-Ann Hayer, Terrance L. Velazquez, Mclain S. Johnson, Brian Graeb

The Prairie Naturalist

Crayfish have an integral role in aquatic ecosystems, serving as herbivores, predators, detritivores, and prey for fishes and other aquatic and terrestrial animals (Momot 1995, Taylor et al. 1996, Martin 1997). Many crayfish populations are currently declining as a result of habitat alteration (Taylor et al. 1996) and invasive predators (e.g., rusty crayfish Orconectes rusticus [Girard; Lodge et al. 2000]). Knowledge of crayfish distribution and biology in North America and specifically North Dakota is sparse or lacking (Taylor et al. 1996) and baseline information is necessary to identify effects of anthropogenic alterations. Early inventories documented 3 crayfish species in North …

Prevalence Of Myxobolus Cerebralis Infections Among Genetic Lineages Of Tubifex Tubifex At Three Locations In The Madison River, Montana, Nilanjan Lodh, Lori Stevens, Billie Kerans

Clinical Lab Sciences Faculty Research and Publications

Host biodiversity can impact disease risk and influence the transmission of parasitic disease. Stream sediment–dwelling worms, Tubifex tubifex (Clitellata: Oligochaeta), are the definitive host of the parasite Myxobolus cerebralis (Myxozoa: Myxosporea), which causes whirling disease in salmonid fishes. Genetic diversity of T. tubifex is correlated with host susceptibility to M. cerebralis, and mitochondrial Lineage III is generally shown to be more likely to be infected and produce the triactinomyxon (TAM) spores than other lineages. We determined the mitochondrial lineage, relative abundance, and prevalence of infection of T. tubifex collected at 3 sites in the Madison River, Montana, where previous …

Thinking About Peace Today, Michael Allen Fox

The Journal of Sociology & Social Welfare

Discussing peace-and how to get to and maintain situations, practices, and socio-political structures that build peace-is of the greatest urgency. But the first step, both psychologically and epistemologically, is overcoming preoccupation with war and resistance to thinking about peace. This article takes on these problems and lays essential groundwork for substantive discussion of peace. Attractions of war and myths of war are deconstructed, and negative views of humans' capacity for peaceful behavior are examined and rejected. Wide-ranging costs of war and war-preparedness are also exposed. The value of peace is then discussed. A concluding section offers a list of "home …

Students For Peace: Contextual And Framing Motivations Of Antiwar Activism, Eric Swank, Breanne Fahs

The Journal of Sociology & Social Welfare

This article traces the development of peace activism among undergraduate social work students. In doing so, it explores how social statuses, political contexts, and collective action frames affect the likelihood of joining the movement against the Afghanistan war (2001 to current). After analyzing data from a multicampus sample of Bachelors in Social Work (BSW) students (n = 159), results show that peace activism was predicted by level of education as well as perceptions of proper foreign policy, the relative efficacy of social movement tactics, and identification with specific activist ideals. Finally, being situated in activist networks fostered greater peace activism …

Bernece Berkman And The Monograph: A Feminist Perspective, Audrey E. Carie

College of Liberal Arts & Social Sciences Theses and Dissertations

Bernece Berkman is one of many renowned women artists who has not been historically acclaimed. As women artists have been rediscovered, issues have arisen as to how they should be written about in relation to art history, because the language and canon of art history has revolved around and privileged those of dominant ideology. Writing about women artists using the current conventions of art history is using the same standards that initially marginalized women artists and artists who are not white, middle-upper class, heterosexual, Christian males. Therefore, it is necessary to consider a new language and system of evaluating art …

Predicting Soil Erosion In The Santa Rosa Creek Watershed Using Rusle2 And Geographic Information Systems, Stacey Carol Smith

Master's Theses

The Santa Rosa Creek watershed is one of the most pristine watersheds on California’s Central Coast.  Preserving this watershed is of great interest because it provides rich soils for agriculture, vast rangelands for cattle, and flowing streams for federally threatened species such as steelhead trout.  Soil erosion could impact these resources.  Using prediction tools, it is possible to study the erosion that could be occurring in a watershed and identify locations which could contribute the highest amounts of sediment.  The objectives of this study were to use RUSLE2 and Geographic Information Systems (GIS) to predict soil erosion rates for each …

Transverse Isotachophoresis Using Polyacrylamide Gel Electrodes, Mark P. Stambaugh

Master's Theses

Separation and isolation of a desired analyte from an impure sample solution containing numerous unwanted interfering agents is the first step of nearly every laboratory test performed in medicine and biology. Nucleic acids are often of particular interest to doctors and researchers, and although methods currently exist for their isolation, these procedures are costly in time, man-power, and real-estate. In addition to easing the execution of presently performed tests, mitigation or elimination of these drawbacks would make a large range of currently unperformed tests both practical and feasible.

This thesis presents a microfluidics-based approach to the isolation of nucleic acids …

Magnetostatic Modeling for Microfluidic Device Design

Kirsten Marie Jackson

For several years, biologists have used superparamagnetic beads to facilitate biological separations. More recently, researchers have adopted this approach in microfluidic devices [1-3]. This recent development and use of superparamagnetic particles in biomedical and biological applications have resulted in a necessity for methods that enable the understanding and prediction of their properties and actions during use. Typically, such methods would involve simple experimentation prior to in vitro experimentation, animal testing, and finally clinical testing. To better understand and unleash this technology, COMSOL®, which is a finite element analysis and multiphysics simulation …

Automated Sg-Dbr Tunable Laser Calibration Optimized For Optical Coherence Tomography Applications, Christopher Louis Chiccone

Master's Theses

SG-DBR lasers look to solve many problems associated with present OCT sources by being cost effective, smaller in size, more robust, and by operating at faster repetition rates.  Swept Source Optical Coherence Tomography (SS-OCT) requires a tunable laser source that exhibits linear frequency sweeps, large frequency spans, and high repetition rates.  This work accomplishes this by using four synchronized waveforms sent to the input of a Sampled Grating-Distributed Bragg Reflector (SG-DBR) laser.  Three mirrors control the wavelength, while an internal semiconductor optical amplifier controls the laser output power.  In dealing with this complicated tuning mechanism, a manual sweep calibration is …

Investigation Of Microalgae Growth Kinetics Using Coal-Fired Flue Gas As A Carbon Source, Bryan Daniel Brooker

Master's Theses

ABSTRACT

Investigation of Microalgae Growth Kinetics using Coal-Fired Flue Gas as a Carbon Source

Bryan Daniel Brooker

Energy related carbon dioxide (CO₂) emissions make up the majority of the United States’ greenhouse gas emissions. Emissions must be alleviated to reduce the effects of global climate change. Microalgae cultivation sequesters CO₂ while producing biomass. Algal biomass can provide a renewable feedstock for biofuel and electricity production, and ingredients for pharmaceuticals, nutraceuticals, pigments and cosmetics. Utilizing microalgae to mitigate CO₂ emissions encourages energy independence by providing a feedstock for biofuels and offers other potentially profitable avenues for the …

Cluster Thinning Effects On Methoxypyrazine, Resveratrol And Berry Chemistry In Vitis Vinifera Cv. Cabernet Sauvignon, Thomas Jerome Fertel

Master's Theses

Cabernet sauvignon is the most widely planted red wine grape in California and is valued in the hundreds of millions of dollars. Cabernet sauvignon grapes, when severely vigorous or overcropped, can contain vegetal aromas and flavors when harvested. 3-alkyl-methoxypyrazines are the volatile compounds responsible for this effect and can lower the perceived quality of the wine. Resveratrol is a phytoalexin that has many medical and health benefits and can be found in red wines. An experiment was conducted in Paso Robles, CA to assess the effects of five yield levels, manipulated through cluster thinning, on methoxypyrazine and resveratrol concentrations. Berry …

A Neural Network Receiver For Em-Mwd Communication, Timothy P. Whitacre

Master's Theses

Baseband digital communication in electro-magnetic measurement while drilling (EM-MWD) systems is often corrupted by non-white surface noise. The inability to reliably decode the transmitted signals in a noisy environment limits the depth at which EM-MWD systems can operate. Correlation receivers, which are optimal in the presence of additive white Gaussian noise, can be sub-optimal in the presence of various types of field noise at different drilling sites.

This thesis investigates the application of artificial neural networks (ANN) as communication receivers in EM-MWD baseband digital communication systems. The performances of various ANN architectures and training algorithms are studied and compared with …

Poroelastic Finite Element Analysis Of A Heterogeneous Articular Cartilage Explant Under Dynamic Compression In Abaqus, Kelsey Kiyo Kam

Master's Theses

A poroelastic finite element model of a heterogeneous articular cartilage disc was

created to examine the tissue response to low amplitude (± 2% strain), low

frequency (0.1 Hz) dynamic unconfined compression (UCC). A strong correlation

has been made between the relative fluid velocity and stimulation of

glycosaminoglycan synthesis. A contour plot of the model shows the relative fluid

velocity during compression exceeds a trigger value of 0.25 μm/s at the radial

periphery. Dynamic UCC biochemical results have also reported a higher

glycosaminoglycan content in this region versus that of day 0 specimens. Fluid

velocity was also found not to be …

Molecular Analysis Reveals Unique Microbiome In Ileal Pouch During Pouchitis Compared To Healthy Pouches In Ulcerative Colitis And Familial Adenomatous Polyposis, Tiffany Wallingford Glavan

Master's Theses

In severe cases of ulcerative colitis (UC) unresponsive to current treatment options, patients require a complete proctocolectomy, or surgical removal of the colon. Ileal pouch anal anastomosis (IPAA) has become the preferred surgical technique for patients who require surgery, as this method restores rectal function. This procedure is also used to treat colorectal cancers such as adenocarcinoma and familial adenomatous polyposis (FAP). The surgery involves an abdominal colectomy with the construction of an ileal pouch created from folded tissue recovered from the ileal portion of the small intestine. Up to 50% of patients who require IPAA surgery experience an episode …

An Efficient Primer Selection Process Combining Progressive And Iterative Multiple Sequence Alignment Strategies: Clustalw And Hmmer, Michael C. Green

Master's Theses

This thesis describes a method for using a computationally efficient algorithm to identify candidate DNA primer sequences. DNA sequencing primers are a critical element of polymerase chain reaction (PCR) and DNA sequence analysis.  A variety of methods for deriving DNA primers exist, but such methods are often computationally intensive, or do not use available sequence data that could potentially serve as a possible resource for primer identification.  Though no current algorithm exists which will always yield a correct primer for every need, evaluation of multi-sequence alignments may provide a reliable source for primer candidates.  However, an exact mathematical solution for …

Rfid Classroom Management System, Andrew W. Wright

Master's Theses

Professors who manage large classes are unrealistically expected to grade each student fairly and accurately.  Even with all of the technological advancements that have occurred in the past thirty years, very little progress has been made in classroom management, and as a result, professors are not equipped with enough tools to successfully manage large class sizes.  Because radio frequency identification (RFID) technology is making its way into student issued identification cards, there is an opportunity to use it as a tool to aid professors in the classroom.  The focus of this paper is to discover the most effective system that …

Assessment And Improvement Of Fire Resiliency For Structures Located In The Wildland-Urban Interface, Allen L. Meskimen

Master's Theses

The purpose of this research was first to study the Wildland-Urban Interface and Wildland-Urban Intermix (WUI) fire problem, and then to design, develop and implement improved fire assessment and fire protection features for structures in the these interface fire-prone areas. The findings included that several areas of the world are prone to devastating fires that claim lives and destroy property, and their fire problems continue to exacerbate. None of these compare to the property loss experienced in Southern California due to its vast development in fire prone areas. It is because of the continuing huge property loss and frequency of …

Harmful Algal Bloom (Hab) Communities And Co-Occurring Species In Relation To Near Shore Ocean Dynamics In San Luis Bay, California, Samuel Christopher Rankin

Master's Theses

The occurrence of phytoplankton taxa, with special focus on harmful algal bloom (HAB) taxa, was monitored for one year off the central coast of California to examine both their co-occurrence and physical and chemical variables influencing their temporal patterns. Bi-weekly samples were taken from October 6, 2008 to October 5, 2009 in San Luis Obispo Bay, CA. Canonical correspondence analysis (CCA) of weekly samples indicated that 46.1% of the variability in species abundance was explained by the variables in the model, higher than previous reports. Cluster analysis divided phytoplankton communities into HAB and non-HAB groups of species, while shared distribution …

Short-Distance Translocation Of The Northern Pacific Rattlesnake (Crotalus O. Oreganus): Effects On Volume And Neurogenesis In The Cortical Forebrain, Steroid Hormone Concentrations, And Behaviors, Matthew L. Holding

Master's Theses

The hippocampus of birds and mammals has been shown to play a crucial role in spatial memory and navigation. The hippocampus exhibits plasticity in adulthood in response to diverse environmental factors associated with spatial demands placed on an animal. The cortical telencephalon of squamate reptiles has been implicated as a functional homologue to the hippocampus. This study sought to experimentally manipulate the navigational demands placed on free-ranging northern Pacific rattlesnakes (Crotalus o. oreganus) to provide direct evidence of the relationship between spatial demands and neuroplasticity in the cortical telencephalon of the squamate brain. Adult male rattlesnakes were radio-tracked …

Impact Of Exercise On Brain Responses To Visual Food Cues: An Fmri Study, Nero Erezi Evero

Master's Theses

On the basis of a strong body of data, the Institute of Medicine currently recommends at least 60 minutes of exercise per day to prevent body weight gain overtime.  Previous studies have shown that there is no compensatory increase in food intake with this dose of exercise. Ultimately, the brain decides whether to alter food intake.  Surprisingly, no published studies have assessed the impact of exercise on brain activation.  Using functional magnetic resonance imaging (fMRI) and an appetite questionnaire, we investigated the effects of a single bout of aerobic exercise on brain responses to visual food cues and subjective appetite …
