Lakes And Forests As Determinants Of Downstream Nutrient Concentrations In Small Mountain Watersheds, P. D. Brown, Wayne A. Wurtsbaugh, K. Nydick

Watershed Sciences Faculty Publications

Lakes are dynamic processors of nutrients and may hold an active role in modifying the water chemistry of stream systems. In this study, we examine the influence of lakes and an important terrestrial component—forest cover—on the nutrient levels of stream water in 11 Rocky Mountain (Idaho) watersheds. Water samples were collected from the inflow and outflow of lakes with varying amounts of upstream lakes and forested area during spring runoff and summer base flow. During base flow, mean total nitrogen concentrations at the inflow of final lakes were significantly related to relative upstream lake area, increasing from 34 to 103 …

Lytic Transglycosylases: Bacterial Space-Making Autolysins, Edie Scheurwater, Christopher W. Reid, Anthony J. Clarke

Science and Technology Department Faculty Journal Articles

Lytic transglycosylases are an important class of bacterial enzymes that act on peptidoglycan with the same substrate specificity as lysozyme. Unlike the latter enzymes, however, the lytic transglycosylases are not hydrolases but instead cleave the glycosidic linkage between N-actetylmuramoyl and N-acetylglucosaminyl residues with the concomitant formation of a 1,6-anydromuramoyl product.

Comparisons In The Cranial Form Of The Blackfeet Indians: A Reassessment Of Boas' Native American Data, Jenee Caprice Gesler

Graduate Student Theses, Dissertations, & Professional Papers

Franz Boas proposed almost one hundred yeas ago that cranial plasticity explained the differences in cranial form between European-born immigrants and their American-born children. Plasticity refers to the idea that the body responds to environmental forces during growth and development. If the environment does affect cranial growth and development, than differences should be seen in populations living under different ecological conditions. In this study anthropometric measurements will be used to test for differences in head and face measurements of members of the Blackfeet Nation using multivariate statistics. The tests are designed to detect differences between the three tribes of the …

The Edge Effect: Lateral Habitat Ecology Of An Alluvial River Flood Plain, Michelle Louise Anderson

Graduate Student Theses, Dissertations, & Professional Papers

We describe the ecology of off-channel or "lateral" habitats as key attributes of the Shifting Habitat Mosaic (SHM) of a river flood plain at the Nyack Research Natural Area in northwestern Montana. Our working hypothesis was that lateral habitats are important to the cycling of energy and materials within the SHM and contribute greatly to the productivity and biodiversity of the floodplain ecosystem. We produce a quantitative description of temperature variation across aquatic and terrestrial habitats at Nyack. Thermal patterns across lateral habitats indicate vast differences exist between lateral habitats in habitat suitability for aquatic organisms over an annual cycle. …

The Methane Range: Coalbed Methane Development, Sage-Grouse Protection, And The Ranching Way Of Life, Jonathan George Hayes

Graduate Student Theses, Dissertations, & Professional Papers

Coalbed methane development has proliferated across much of the western United States. Campbell County, Wyoming, in the Powder River Basin is one area that has seem some of the highest amounts of this development, most of it occurring on land where the surface use is livestock grazing, resulting in conflicts over resource use. This thesis takes a grounded theory approach to understanding the meaning that the ranchers that operate on this land have attached to this development. In doing so, this paper argues that these ranchers form opinions and attitudes based on how CBM has affected “the ranching way of …

This thesis questions why the province of Almería has the highest concentration of greenhouses in the world and determines what processes led to this industry. The research focuses on local-global scale interactions and environmental history analysis within a political ecology framework. The methods for data collection included literature review of secondary sources and four months living in Almería conducting interviews and field observations. Located in Europe’s driest desert, the greenhouses of Almería …

Evaluating The Design And Management Of Community-Based Ecotourism Projects In Guatemala, Kassandra Lynne Miller

Graduate Student Theses, Dissertations, & Professional Papers

Community-based ecotourism (CBE) has become the newest buzzword in development circles for its purported ability to provide alternative income generation for families and incentives to protect natural resources. Organizations such as the World Bank, World Wildlife Federation and USAID have supported these small-scale projects across the globe. However, there has been much debate over the efficacy of these projects. They are often developed, managed, and even owned by NGOs, not by local communities. Economic benefits resulting from the project are often directed toward one or two people in prominent positions within the community and not evenly distributed. The increase in …

Sage-Grouse And Energy Development: Integrating Science With Conservation Planning To Reduce Impacts, Kevin Eric Doherty

Graduate Student Theses, Dissertations, & Professional Papers

Effective conservation planning in the face of rapid land use change requires knowledge of which habitats are selected at landscape scales, where those habitats are located, and how species ultimately respond to anthropogenic disturbance. I assessed sage-grouse (Centrocercus urophasianus) large scale habitat ecology and response to energy development in the winter and nesting seasons using radio-marked individuals in the Powder River Basin, Montana and Wyoming, USA. Landscape scale percent sagebrush (Artemisia spp.) cover at 4-km2 was the strongest predictor of use by sage-grouse in winter. After controlling for vegetation and topography, the addition the density of coal-bed natural gas wells …

Shame, Guilt And Society's Conception Of Sex, Hailey M. Magsig

Graduate Student Theses, Dissertations, & Professional Papers

There is a dominant conception of sex in American society that has profound effects on our sexual lives. Often this can be a negative influence because our society’s conception is distorted. My thesis considers how this skewed view on sex and sexuality results in the presence of shame and guilt in our sexual lives. I first define society’s conception of sex and present it visually through fashion advertising. Each of the pornographic elements (objectification, submission, hierarchy and violence) utilized in advertising are explained. The advertisements are meant to provide a visual portrayal of society’s conception of sex, which is relevant …

Spatial Population Dynamics Of Western Painted Turtles In A Wetland Ecosystem In Northwestern Montana, Kathleen Ann Griffin

Graduate Student Theses, Dissertations, & Professional Papers

Population dynamics are driven by the interplay between the positive forces of births and immigration and the negative forces of deaths and emigration. Understanding dynamics at the local and metapopulation level is key in wildlife conservation. Although data on turtle survival and movement rates are available, few studies use rigorous statistical analyses and none include examination of stage-specific seasonal survival simultaneous with movement estimates. I used capture-mark-recapture methods to estimate apparent survival rates and movement probabilities of adult and juvenile western painted turtles (Chrysemys picta bellii) across space and time in a wetland ecosystem in northwestern Montana. All wetlands within …

Cold Atmospheric Pressure Air Plasma Jet For Medical Applications, Juergen Friedrich Kolb, A.-A H. Mohamed, R. O. Price, R. J. Swanson, A. Bowman, R. L. Chiavarini, Michael W. Stacey

Bioelectrics Publications

By flowing atmospheric pressure air through a direct current powered microhollow cathode discharge, we were able to generate a 2 cm long plasma jet. With increasing flow rate, the flow becomes turbulent and temperatures of the jet are reduced to values close to room temperature. Utilizing the jet, yeast grown on agar can be eradicated with a treatment of only a few seconds. Conversely, animal studies show no skin damage even with exposures ten times longer than needed for pathogen extermination. This cold plasma jet provides an effective mode of treatment for yeast infections of the skin.

Suicides Among Farmers In Three Southeastern States, 1990-1998, Steven R. Browning, Susan C. Westneat, Robert H. Mcknight

Epidemiology and Environmental Health Faculty Publications

Several studies have documented higher rates of suicide among farmers in comparison to other occupational groups, both in the U.S. and internationally. The purpose of this study is to describe the epidemiology of farmer suicides in three southeastern states (Kentucky, North Carolina, and South Carolina) during the nine-year period 1990-1998. Electronic death certificate data were obtained from the National Center for Health Statistics. Over the nine-year period, there were 590 deaths related to suicide (E-codes: 950-959) among farmers (occupation codes: 473, 474, 475, 477, and 479) in the states of Kentucky, North Carolina, and South Carolina. The results of this …

Adolescent Mothers: The Space Between What They Know And What They Do, Nicole Catherine Mccray

Graduate Student Theses, Dissertations, & Professional Papers

Although the current rate of teen pregnancy in the United States is at a historic low (Martin et al., 2007), there are a number of risk factors associated with early parenthood. Adolescent parenthood is often embedded in a larger context of risk such as poverty, single parenthood, low educational attainment, a history of physical and emotional abuse, and engagement in risky behavior (Hans & Wakschlag, 2000). As parents, adolescent mothers tend to be less knowledgeable about child development, less stimulating in interactions with infants, less tolerant, and more punitive with punishment (Brooks-Gunn & Furstenberg, 1986). The children of adolescent mothers …

Conservation Of Pheasants In North West Frontier Province, Pakistan, Iftikhar Uz Zaman

Graduate Student Theses, Dissertations, & Professional Papers

Pheasants belong to the avian order Galliformes and are important environmental indicators. Among 49 species of pheasants in the world, 5 of them are endemic to Pakistan with distribution in the Himalaya and remote northern parts of the country. Due to increase in human population, encroachment, poaching, and habitat disturbance pheasants are threatened and vulnerable. Besides ecological importance of pheasants they have also aesthetic values which mainly contribute to their decline in population in wake of poaching in their native local habitat. Because cheer pheasant was extirpated locally and other pheasants were declared endangered or threatened by the 1UCN, the …

Feminist Pragmatism In The Work Of Justice Bertha Wilson, Colleen Sheppard

The Supreme Court Law Review: Osgoode’s Annual Constitutional Cases Conference

This paper explores the influence of feminism and pragmatism on the work of Justice Bertha Wilson. Inspired by a commitment to promoting equality and advancing justice, Justice Wilson’s approach to judging resonates with feminist pragmatism. This orientation is illustrated by the approach to legal interpretation that she endorsed — an approach that was premised upon the centrality of social context and experiential knowledge rather than abstract legal formalism. Furthermore, she sought to make decisions that advanced social justice, despite her understanding that there were often no ideal solutions in concrete legal cases. Thus, she made decisions that resolved specific legal …

What Is Left Of Pelech?, Robert Leckey

The Supreme Court Law Review: Osgoode’s Annual Constitutional Cases Conference

This paper takes Justice Wilson’s majority judgments in the Pelech v. Pelech trilogy (1987) as point of departure for an inquiry into the life over time of family law judgments and family law scholarship. It argues that it is worth attending to the ways in which the experience of critically reading those judgments today is different than it was at the time of their release. A contemporary rereading of the trilogy and of the sophisticated feminist literature critical of it shows the contingency of scholarly interventions. Subsequent developments in political economy, notably the intensified downloading of the state’s responsibility for …
