Bpv Entry And Trafficking In Ebtr Cells, Enkhmart Dudleenamjil Nov 2009

Bpv Entry And Trafficking In Ebtr Cells, Enkhmart Dudleenamjil

Theses and Dissertations

Bovine Parvovirus (BPV) belongs to the genus Bocavirus, family Parvoviridae. BPV is the leading etiologic agent among the pathogens that cause primary gastroenteritis of cattle. Many of the intracellular events associated with virus replication are unknown. In this research project, we investigated BPV internalization into the host cell and trafficking in the cytosol. Preliminarily, EBTr cells had abundant clathrin, virus attached to purified clathrin, and EM micrographs revealed virus in endocytic vacuoles. Assays detecting virus infectivity (i.e. viral protein synthesis), virus production (completion of the replication cycle), and quantitative PCR (qPCR) to detect viral transcripts were used to evaluate …

Emerging Adulthood In India, Liann Nicole Seiter Nov 2009

Emerging Adulthood In India, Liann Nicole Seiter

Theses and Dissertations

This paper explores the nature of emerging adulthood in Southern India. Survey data was collected from 450 college students in Coimbatore, Tamil Nadu, India and 100 non-students from rural villages surrounding Coimbatore. Unlike American samples, the majority of the 18- to 26-year-olds studied felt that they had achieved adulthood. The sample emphasized attributes needed to fulfill family roles as characteristics necessary for adulthood. Differences in optimism levels were found between students and non-students. Arnett suggests that emerging adulthood would be affected by cultural influences. The unique cultural and structural influences in India such as, Hinduism, caste, gendered socialization, and the …

Remembering The Ghost: Pedro Páramo And The Ethics Of Haunting, Benjamin Cluff Nov 2009

Remembering The Ghost: Pedro Páramo And The Ethics Of Haunting, Benjamin Cluff

Theses and Dissertations

This study seeks to describe what I term the ethics of haunting, as related to trauma and memory, by analyzing Juan Rulfo's Pedro Páramo. It does not claim to be representative of ghosts and haunting as a whole, but more specifically to illustrate various manners in which the return of the ghost and its subsequent haunting are motivated by an ethics of memory in Rulfo's novel. Within this framework I explore remembrance as a medium of exchange between the living and the dead, haunting as a method by which gaps in the historical archive can be filled, and the …

Optimizing The Release And Methylation Of Bacterial Endospore Dipicolinic Acid, Aaron N. Nackos Nov 2009

Optimizing The Release And Methylation Of Bacterial Endospore Dipicolinic Acid, Aaron N. Nackos

Theses and Dissertations

Rapid, portable detection of biological threat agents such as Bacillus anthracis endospores (“spores”) is extremely important given the real and perceived threats of bioterrorism. Gas chromatography-mass spectrometry (GC-MS) is an excellent general means for chemical detection, although special sample preparation and specialized equipment are required to employ GC-MS for detecting biological agents such as spores in the field. A GC sample introduction probe consisting of a helical wire that can be retracted inside a syringe needle, called a coiled wire filament (CWF), was employed as a simple, passively-heated means to introduce the mixture of spores plus reagents for thermochemolysis methylation …

Chemalign: Biologically Relevant Multiple Sequence Alignment Using Physicochemical Properties, Hyrum Carroll, Mark J. Clement, Quinn O. Snell, David Mcclellan Nov 2009

Chemalign: Biologically Relevant Multiple Sequence Alignment Using Physicochemical Properties, Hyrum Carroll, Mark J. Clement, Quinn O. Snell, David Mcclellan

Faculty Publications

We present a new algorithm, ChemAlign, that uses physicochemical properties and secondary structure elements to create biologically relevant multiple sequence alignments (MSAs). Additionally, we introduce the Physicochemical Property Difference (PPD) score for the evaluation of MSAs. This score is the normalized difference of physicochemical property values between a calculated and a reference alignment. It takes a step beyond sequence similarity and measures characteristics of the amino acids to provide a more biologically relevant metric. ChemAlign is able to produce more biologically correct alignments and can help to identify potential drug docking sites.

Why We Don't Understand The Rule Of Law, Noel B. Reynolds Oct 2009

Why We Don't Understand The Rule Of Law, Noel B. Reynolds

Faculty Publications

This paper presents an assessment of current theories of law and their continuing failure to account in a convincing way for the rule of law as an ideal that guides and reassures modern democratic societies. It then explores the possibility that emerging understandings of human evolution and brain function may help us understand the process of convention making in a way that could reveal the underlying moral and epistemological context of law and allow us to identify a complete set of standards for the rule of law in human societies.

Effects Of Simulated Mountain Lion Caching On Decomposition Of Ungulate Carcasses, Zachary Bischoff-Mattson, David Mattson Oct 2009

Effects Of Simulated Mountain Lion Caching On Decomposition Of Ungulate Carcasses, Zachary Bischoff-Mattson, David Mattson

Western North American Naturalist

Caching of animal remains is common among carnivorous species of all sizes, yet the effects of caching on larger prey are unstudied. We conducted a summer field experiment designed to test the effects of simulated mountain lion (Puma concolor) caching on mass loss, relative temperature, and odor dissemination of 9 prey-like carcasses. We deployed all but one of the carcasses in pairs, with one of each pair exposed and the other shaded and shallowly buried (cached). Caching substantially reduced wastage during dry and hot (drought) but not wet and cool (monsoon) periods, and it also reduced temperature and …

Burrow Occupancy Patterns Of The Western Burrowing Owl In Southern Nevada, Paul D. Greger, Derek B. Hall Oct 2009

Burrow Occupancy Patterns Of The Western Burrowing Owl In Southern Nevada, Paul D. Greger, Derek B. Hall

Western North American Naturalist

Understanding long-term patterns of burrow occupancy for the Western Burrowing Owl (Athene cunicularia hypugaea) is necessary for the conservation of this species, especially in arid, desert ecosystems where burrow occupancy data are lacking. Monthly burrow monitoring was conducted over a 4-year period (1997–2001) in southern Nevada to determine burrow occupancy patterns of Burrowing Owls and to evaluate the effects of burrow type and desert region on burrow occupancy. Burrow occupancy occurred year-round and was most consistent in the Transition region and tended to be lowest in the Mojave Desert region. Peak burrow occupancy occurred during March through May, …

Caddisfly (Trichoptera) Assemblages Along Major River Drainages In Arizona, Dean W. Blinn, David E. Ruiter Oct 2009

Caddisfly (Trichoptera) Assemblages Along Major River Drainages In Arizona, Dean W. Blinn, David E. Ruiter

Western North American Naturalist

Seventy-two caddisfly species in 36 genera and 15 families were collected along the Little Colorado, Verde, Gila, and Colorado rivers in Arizona. Brachycentrids, hydropsychids, limnephilids, and uenoids made up nearly 50% of the assemblage in forested sites above 2200 m. Hydropsychids, hydroptilids, and leptocerids made up 75% of the assemblage in grassland watersheds between 2200 and 1000 m, and 80% at sites below 1000 m in desert watersheds. Species richness averaged 16 at sites above 2200 m elevation, 7 between 2200 and 1000 m, and 3 below 1000 m. H′ diversity was typically >3 at sites above 2200 m and <2.5 below 2200 m. Each river had distinct faunas likely due to isolation of drainages across semiarid landscapes. Low Sørensen similarity values were measured for caddisfly assemblages in the highly regulated Colorado River and the other 3 rivers. Only 17 species were collected at 14 sites along 700 km of the Colorado River. Indicator caddisfly species are provided for altered and less disturbed drainages. We added 7 species not previously reported in Arizona for a total of 154 caddisfly species in the state. We provide a baseline of caddisfly indicators for monitoring changes in ecosystem health during the predicted long-term drought and population expansion in southwestern USA.

Formation And Contents Of Yellow-Pine Chipmunk (Tamias Amoenus) Winter Larders, Kellie M. Kuhn, Stephen B. Vander Wall Oct 2009

Formation And Contents Of Yellow-Pine Chipmunk (Tamias Amoenus) Winter Larders, Kellie M. Kuhn, Stephen B. Vander Wall

Western North American Naturalist

Despite much attention to the foraging habits and hibernation patterns of food-storing mammals, little is known about the contents of winter larders under natural conditions or how animals prepare a winter larder. Here we describe the contents of 15 yellow-pine chipmunk (Tamias amoenus) winter larders from 3 different years and describe the movement of scatter-hoarded seeds into larders. We found larders by locating 14 radio-collared chipmunks in their winter dens. One additional larder was found by tracking the movement of seeds labeled with radioactive scandium-46 from scattered caches into the larder. Chipmunks formed winter dens and rapidly provisioned …

Distribution Records And Comments On Mammals In Western South Dakota, Steven G. Platt, Zannita Fast Horse, Thomas R. Rainwater, Stanlee M. Miller

Western North American Naturalist

The mammal fauna of western South Dakota is imperfectly known; in particular there is a notable paucity of data from Indian reservations in the region. We collected mammals from January 2003 through May 2006 using a variety of standard methodologies, including trapping with snap-traps and Macabee traps, shooting, and salvaging road- and hunter-killed animals. Herein we provide 23 specimen-based county records representing 17 species of mammals. In addition, a photo record constitutes the first report of Dasypus novemcinctus from South Dakota and the northernmost record in the United States. The possible local extirpation of Marmota flaviventris in the southern Black …

Diel Use Of Water By Reintroduced Bighorn Sheep, Jericho C. Whiting, R. Terry Bowyer, Jerran T. Flinders Oct 2009

Diel Use Of Water By Reintroduced Bighorn Sheep, Jericho C. Whiting, R. Terry Bowyer, Jerran T. Flinders

Western North American Naturalist

Water sources are an important habitat component for populations of bighorn sheep (Ovis canadensis), and the technique of sampling at water sources has been used extensively to study behaviors and estimate parameters of bighorn populations. Little is known, however, concerning the time of day at which groups of bighorns visit water. Understanding when bighorns visit water sources will allow wildlife investigators to conduct sampling when bighorns are most likely to be present at this resource. We quantified use of 7 water sources by reintroduced bighorn sheep during summer 2005 and 2006 on Antelope Island State Park, Utah. Our …

Efficacy Of Two Variations On An Aerial Lek-Count Method For Greater Sage-Grouse, D. T. Booth, S. E. Cox, G. E. Simonds, B. Elmore

Western North American Naturalist

Greater Sage-Grouse (Centrocercus urophasianus) is a species of concern, and accurate population data are needed to monitor conservation management efforts. Conventional, ground-based lek counts are labor-intensive, expensive, and have several sources of potential error and bias, including the practical limits on number and distribution of leks counted. We tested aerial methods for photographing multiple leks during a single morning. We completed 14 aerial approaches to 6 leks in 2 different years using 2 different airplanes and altitudes. Grouse flushed from leks on 12 approaches when the airplane was within 200–300 m of the lek. In 2 instances, strutting …

Relative And Seasonal Abundance Of Three Bark Beetle Predators (Coleoptera: Trogositidae, Cleridae) Across An Elevation Gradient In Ponderosa Pine Forests Of North Central Arizona, Kelly K. Williams, Joel D. Mcmillin, Tom E. Degomez

Western North American Naturalist

We examined abundance and flight periodicity of 3 predators of bark beetles (Coleoptera: Curculionidae, Scolytinae), Temnochila chlorodia (Mannerheim) (Coleoptera: Trogositidae), Enoclerus sphegeus (Fabricius) (Coleoptera: Cleridae), and E. lecontei (Wolcott) (Coleoptera: Cleridae), across an elevational gradient of ponderosa pine (Pinus ponderosa Lawson) forests in north central Arizona. Predator populations were estimated at 10 sites in each of 3 elevation bands (low: 1600–1736 m; mid: 2058–2230 m; high: 2505–2651 m) for 3 years (2004–2006) using pheromone-baited funnel traps targeting 3 primary bark beetle species. We also investigated how predator abundance and flight seasonality related to those of 5 bark beetle species: …

Relationships Between Insolation And Rattlesnake Hibernacula, Bryan T. Hamilton, Erika M. Nowak Oct 2009

Relationships Between Insolation And Rattlesnake Hibernacula, Bryan T. Hamilton, Erika M. Nowak

Western North American Naturalist

We examined the relationship between insolation, climate, and hibernacula of black-tailed (Crotalus molossus), Great Basin (Crotalus lutosus), and western diamondback (Crotalus atrox) rattlesnakes at 4 sites in Arizona, Nevada, and Utah. Hibernacula were located through a combination of visual searches and radio telemetry from 1995 to 2003. We used global information systems to calculate insolation and compared hibernaculum insolation values with random points representing available insolation of the surrounding habitat. Insolation reflects soil temperatures, and we predicted that hibernacula in cool climates, at high elevations, and at high latitudes would have higher insolation relative …
