United States Environmental Protection Agency: Publications

Assessment of potential risks of complex contaminant mixtures in the environment requires integrated chemical and biological approaches. In support of the US Great Lakes Restoration Initiative, the US Environmental Protection Agency lab in Duluth, MN, is developing these types of methods for assessing possible risks of aquatic contaminants in near-shore Great Lakes (USA) sites. One component involves an exposure system for caged fathead minnow (Pimephales promelas) adults suitable for the wide range of habitat and deployment situations encountered in and around the Great Lakes. To complement the fish exposure system, the authors developed an automated device for collection of composite …

Spring Migration Ecology Of The Mid-Continent Sandhill Crane Population With An Emphasis On Use Of The Central Platte River Valley, Nebraska, Gary L. Krapu, David A. Brandt, Paul J. Kinzel, Aaron T. Pearse

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We conducted a 10-year study (1998–2007) of the Mid-Continent Population (MCP) of sandhill cranes (Grus canadensis) to identify spring-migration corridors, locations of major stopovers, and migration chronology by crane breeding affiliation (western Alaska–Siberia [WA–S], northern Canada–Nunavut [NC–N], west-central Canada–Alaska [WC–A], and east-central Canada–Minnesota [EC–M]). In the Central Platte River Valley (CPRV) of Nebraska, we evaluated factors influencing staging chronology, food habits, fat storage, and habitat use of sandhill cranes. We compared our findings to results from the Platte River Ecology Study conducted during 1978–1980. We determined spring migration corridors used by the breeding affiliations (designated subpopulations for management …

Beta‐Thymosin Gene Polymorphism Associated With Freshwater Invasiveness Of Alewife (Alosa Pseudoharengus), Katarzyna Michalak, Serguisz Czesny, John Epifanio, Randal Snyder, Eric Schultz, Jonathan Velotta, Stephen Mccormick, Bonnie Brown, Graciela Santopietro, Pawel Michalak

United States Geological Survey: Staff Publications

Predicting the success of a species' colonization into a novel environment is routinely considered to be predicated on niche‐space similarity and vacancy, as well as propagule pressure. The role genomic variation plays in colonization success (and the interaction with environment) may be suggested, but has not rigorously been documented. To test an hypothesis that previously observed ecotype‐specific polymorphisms between anadromous and landlocked alewife (Alosa pseudoharengus) populations are an adaptive response to osmoregulatory challenges rather than a result of allele sampling at founding, we examined multiple anadromous and landlocked (colonized) populations for their allelic profiles at a conserved region (3’‐UTR end) …

Anatomy Of The Lamprey Ear: Morphological Evidence For Occurrence Of Horizontal Semicircular Ducts In The Labyrinth Of Petromyzon Marinus, Adel Maklad, Caitlyn Reed, Nicolas Johnson, Bernd Fritzsch

United States Geological Survey: Staff Publications

In jawed (gnathostome) vertebrates, the inner ears have three semicircular canals arranged orthogonally in the three Cartesian planes: one horizontal (lateral) and two vertical canals. They function as detectors for angular acceleration in their respective planes. Living jawless craniates, cyclostomes (hagfish and lamprey) and their fossil records seemingly lack a lateral horizontal canal. The jawless vertebrate hagfish inner ear is described as a torus or doughnut, having one vertical canal, and the jawless vertebrate lamprey having two. These observations on the anatomy of the cyclostome (jawless vertebrate) inner ear have been unchallenged for over a century, and the question of …

Fitting Statistical Distributions To Sea Duck Count Data: Implications For Survey Design And Abundance Estimation, Elise Zipkin, Jeffrey Leirness, Brian Kinlan, Allan O'Connell, Emily Silverman

United States Geological Survey: Staff Publications

Determining appropriate statistical distributions for modeling animal count data is important for accurate estimation of abundance, distribution, and trends. In the case of sea ducks along the U.S. Atlantic coast, managers want to estimate local and regional abundance to detect and track population declines, to define areas of high and low use, and to predict the impact of future habitat change on populations. In this paper, we used a modified marked point process to model survey data that recorded flock sizes of Common eiders, Long-tailed ducks, and Black, Surf, and White-winged scoters. The data come from an experimental aerial survey, …

Adverse Outcome Pathway And Risks Of Anticoagulant Rodenticides To Predatory Wildlife, Barnett A. Rattner, Rebecca S. Lazarus, John E. Elliott, Richard F. Shore, Nico Van Den Brink

United States Geological Survey: Staff Publications

Despite a long history of successful use, routine application of some anticoagulant rodenticides (ARs) may be at a crossroad due to new regulatory guidelines intended to mitigate risk. An adverse outcome pathway for ARs was developed to identify information gaps and end points to assess the effectiveness of regulations. This framework describes chemical properties of ARs, established macromolecular interactions by inhibition of vitamin K epoxide reductase, cellular responses including altered clotting factor processing and coagulopathy, organ level effects such as hemorrhage, organism responses with linkages to reduced fitness and mortality, and potential consequences to predator populations. Risk assessments have led …

Novel Gammaherpesvirus Functions 1 Encoded By Bovine Herpesvirus (Bovine Lymphotropic Virus), J. Jia, G. Delhon, E. R. Tulman, D. G. Diel, Fernando A. Osorio, X. Wen, G. F. Kutish, D. L. Rock

School of Veterinary and Biomedical Sciences: Faculty Publications

The genus Macavirus of the subfamily Gammaherpesvirinae includes viruses that infect lymphoid cells of domestic and wild ruminants and swine, causing asymptomatic latent infections in reservoir hosts. Here, we describe the genome of bovine herpesvirus 6 (BoHV-6), a

macavirus ubiquitous in healthy cattle populations. The BoHV-6 genome exhibited architecture conserved in macaviruses, including a repetitive H-DNA region and unique, 141 kilobase pair L

DNA region predicted to encode 77 genes. BoHV-6 encoded in variable genomic regions a novel complement of genes relative to other characterized macaviruses, likely contributing to distinctive aspects of BoHV-6 infection biology and host range. Most notably, …

Chronic Wasting Disease Detection In The Lymph Nodes Of Free-Ranging Cervids By Real Time Quaking-Induced Conversion, Nicholas J. Haley, Scott Carver, Laura Hoon-Hanks, Davin M. Henderson, Kristen A. Davenport, Elizabeth Bunting, Shawn Gray, Judith Galeota, Ivy Levan, Tracy Dubovos, Paul Shelton, Edward A. Hoover, Bruce Trindle

School of Veterinary and Biomedical Sciences: Faculty Publications

Chronic wasting disease (CWD), a transmissible spongiform encephalopathy of deer, elk and moose, is the only prion disease affecting free-ranging animals. First identified in northern Colorado and southern Wyoming in 1967, new epidemic foci of the disease have since been identified in additional states, as well as two Canadian provinces and the Republic of South Korea. Identification of CWD-affected animals currently requires post-mortem analysis of brain or lymphoid tissues using immunohistochemistry (IHC) or an enzyme linked immunosorbent assay (ELISA), with no practical way to evaluate potential strain types or investigate the epidemiology of existing or novel foci of disease. Using …

Radioprotective Efficacy Of Delta-Tocotrienol, A Vitamin E Isoform, Is Mediated Through Granulocyte Colony-Stimulating Factor, Vijay Singh, Stephen Y. Wise, Jessica R. Scott, Patricia L.P. Romaine, Victoria L. Newman, Oluseyi O. Fatanmi

Uniformed Services University of the Health Sciences

Aims: The objectives of this study were to determine the cytokine induction by delta tocotrienol (DT3, a promising radiation countermeasure) and to investigate the role of granulocyte colony-stimulating factor (G-CSF) in its radioprotective efficacy against ionizing radiation in mice. Main methods: Multiplex Luminex was used to analyze cytokines induced by DT3 and other tocols (gammatocotrienol and tocopherol succinate) in CD2F1 mice. Mice were injected with an optimal dose of DT3 and a G-CSF antibody, and their 30-day survival against cobalt-60 gamma-irradiation was monitored. The neutralization of G-CSF by the administration of a G-CSF-specific antibody in DT3-injected mice was investigated by …

Commgram: A New Visual Analytics Tool For Large Communication Trace Data, Jieting Wu, Jianping Zeng, Hongfeng Yu

School of Computing: Conference and Workshop Papers

The performance of massively parallel program is often impacted by the cost of communication across computing nodes. Analysis of communication patterns is critical for understanding and optimizing massively parallel programs. Visualization can help identify potential communication bottlenecks by displaying message trace data. However, the visual clutter and temporal incoherence problems are typically incurred in existing visualization tools for a considerable number of processors. In this paper, we present a new tool, named CommGram, which supports visual analysis of communication patterns for massive parallel MPI programs. With the benefit of MPI trace library DUMPI of SST, our framework builds hierarchical …

A Resilience-Based Approach To The Conservation Of Valley Oak In A Southern California Landscape, James J. Hayes, Shannon Donnelly

Geography and Geology Faculty Publications

Conservation thinking will benefit from the incorporation of a resilience perspective of landscapes as social-ecological systems that are continually changing due to both internal dynamics and in response to external factors such as a changing climate. The examination of two valley oak stands in Southern California provides an example of the necessity of this systems perspective where each stand is responding differently as a result of interactions with other parts of the landscape. One stand is experiencing regeneration failure similar to other stands across the state, and is exhibiting shifts in spatial pattern as a response to changing conditions. A …

Presumed Imminence: Judicial Risk Assessment In The Post-9/11 World, Avidan Y. Cover

Faculty Publications

Court opinions in the terrorism context are often distinguished by fact-finding that relates to risk assessment. These risk assessments — inherently policy decisions — are influenced by cultural cognition and by cognitive errors common to probability determinations, particularly those made regarding highly dangerous and emotional events. In a post-9/11 world, in which prevention and intelligence are prioritized over prosecution, courts are more likely to overstate the potential harm, neglect the probability, and presume the imminence of terrorist attacks. As a result, courts are apt to defer to the government and require less evidence in support of measures that curtail civil …

Modelling The Effects Of Natural Antimicrobials As Food Preservatives, Amit Jaiswal, Swarna Jaiswal

Books/Book Chapters/ Proceedings

A predictive food microbiological model is a mathematical representation of mechanisms that describes the growth, survival, inactivation or biochemical process of an organism and are used in the food industry to predict food pathogen growth and to help in the evaluation of food safety. Furthermore, it reduces the number of expensive and time-consuming experiments; however, adequate statistical analysis is a crucial step during all phases of model development and validation. Therefore, the present chapter is focused on the basic concept of mathematical modelling which can be applied to estimate the effects of natural antimicrobials as food preservatives. Initial section discusses …

'As A Woman, As A Mother, As A Farmer': Understanding Women's Agricultural Practices, Perceptions And Adaption To Climate Change In The Upper Midwest, Erin Kline

Electronic Theses and Dissertations

This research shows that women’s farming identities are changing inline with their increased representation in agriculture in general, but specifically reflective of women’s increased autonomy in decision-making. This is especially evident among women who are primary operators, but increased equality is also apparent for women farming in partnerships. These key findings align with current identity research (see Brasier et al. 2014) and demonstrate the multiplicity of roles that women fulfill on the farm, and how these roles change in alignment with farming practices. This exploratory research draws from Feminist standpoint theory and situated knowledge to develop qualitative interview protocol to …

Toward A Conceptualization Of Emetophobia: Examining Intolerance Of Uncertainty As A Unique Predictor Of Symptoms, Mimi Zhao

Electronic Theses and Dissertations

Emetophobia, a poorly understood disorder, is a specific phobia characterized by an irrational and persistent fear of oneself vomiting or others vomiting. Though research on the disorder is sparse, previous investigations have reported interference in social, occupational, and health domains in the lives of individuals with emetophobia (Lipsitz et al., 2001; McFayden & Wyness, 1983; Veale & Lambrou, 2006). To this end, the current study examined whether individual differences in Anxiety Sensitivity (AS), Disgust Sensitivity (DS), and Intolerance of Uncertainty (IU) are associated with symptoms of emetophobia, whether AS predicts symptoms of emetophobia above and beyond DS, IU, and expected …

Why Aren't More Heathens Eco-Pagan Vegetarians? The Intersection Of Gender, Politics, And Spiritual Environmentalism, Kristen An Horton

Electronic Theses and Dissertations

Neo-Paganism, a nature-based new religious movement, provides a rich backdrop for the study of spiritual environmentalism. This ethnographic project analyzes the dynamic interconnectedness of neo-paganism and environmentalism, or "eco-paganism," and how Heathenry reframes the natural world using interpretations of Old Norse lore. A Heathen's connection to nature and how this connection is incorporated into his/her daily life supports the idea of environmentalism, yet their patriarchal and conservative political beliefs devalue environmentalism. My focus is on the feminization of the environment and vegetarianism to such a degree that Heathens view these movements as radicalized liberal tree hugging hobbies and how these …

Mississippi Motoring: Mom And Pops And Entrepreneurs, Erin Elizabeth Scott

Electronic Theses and Dissertations

In the 21st century, motorists driving "off the beaten path" and not on the interstate now have the treat of gaining insight into a local area's foodways when they stop to eat. From tamales to the local fried experiment, gas stations have evolved to provide one stop shopping for the day tripper or sustenance and social interaction within a locale. The state of Mississippi has somewhat escaped the national burger or sandwich chain connected to the service station and instead has a "mom and pop" kitchen serving up often informal and local flavors. How do these establishments make a go …

Determinants Of Bite Force In Four Species Of Sharks From The Gulf Of Mexico With An Emphasis On The Atlantic Sharpnose Shark, Rhizoprionodon Terraenovae, Kyle Walter Rice

Electronic Theses and Dissertations

Bite force can provide valuable information regarding the physiological ecology of an organism. However, there have been few studies wherein bite force in sharks has been considered. Herein I report on a study of the bite force of four species of sharks with particular emphasis on that of the atlantic sharpnose shark, rhizoprionodon terraenovae. Among the four species examined, blacktip shark, carcharhinus limbatus bite force was significantly higher than that of sharpnose, rhizoprionodon terraenovae. There was no significant difference between the bite force of those species compared with the same for finetooth shark, c. Isodon and spinner shark, c. Brevipinna. …

Transformation Of Early Nineteenth Century Chickasaw Leadership Patterns, 1800-1845, Emily Paige Smithey

Electronic Theses and Dissertations

This is an examination of the changing leadership patterns of the Chickasaw Nation during the early nineteenth century, and combines the internal function of Chickasaw government with the leaders' responses to overwhelming external factors. This thesis begins in 1800, a time that hinges on the remnant Chickasaw political leadership offices of previous centuries, such as the Minko and Tisho Minko, combined with the formation of newer offices such as district chiefs. It ends in 1845 after the Chickasaws were forced to remove from their Mississippi homelands into the Indian Territory. After removal, the Chickasaws began a more centralized form of …

Understanding Strawberry Plains Through Landscape Archaeology, Leeanne Wendt

Electronic Theses and Dissertations

Strawberry Plains is a site that is located in Marshall County, Mississippi and is comprised of Woodland, Chickasaw, antebellum, and postbellum components. The focus of this thesis was placed on the postbellum time period. The information presented here is intended to give a comprehensive view into the lives of the sharecroppers that resided and worked on Strawberry Plains during the early to mid-twentieth century and also understand the economic relationship between them and the landowner. Also of importance to this project was the placement of the houses and their dispersed pattern across the landscape and comparing this pattern to other …

Pretreatment Of Cellulosic Biomass By Iron-Containing Magnetic Ionic Liquid Dissolution, Christopher Roth Riley

Electronic Theses and Dissertations

The focus of this project is to determine the effectiveness in the preprocessing of biomass when magnetic ionic liquids (MIL) (1-butyl-3-methylimidazolium tetrachloroferrate (Bmim[FeCl4]) and 1-ethyl-3-methylimidazolium tetrachloroferrate (Emim[FeCl4])) are used as a green solvent. Lignocellulose is a promising starting material for a plethora of products, ranging from biofuels to custom chemicals; however, lignocellulose is resistant to enzymatic degradation. Various biomass-preprocessing techniques such as microbial, mechanical, and chemical pretreatment are used for enhancing the digestibility of biomass to sugars for ethanol production. Varieties of ionic liquids have demonstrated the ability to fragment lignocellulose. However, after fragmentation, separation of biomass and ionic liquids …
