Pervasive Thermal Consequences Of Stream-Lake Interactions In Small Rocky Mountain Watersheds, Usa, Jessica D. Garrett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Limnologists and stream ecologists acknowledge the fundamental importance of temperature for regulating many ecological, biological, chemical, and physical processes. I investigated how water temperatures were affected by hydrologic linkages between streams and lakes at various positions along surface water networks throughout several headwater basins in the Sawtooth and White Cloud Mountains of Idaho (USA). Temperatures of streams and lakes were measured for up to 27 months in seven 6 – 41 km² watersheds, with a range of lake influence. When they were ice-free, warming in lakes resulted in dramatically warmer temperatures at lake outflows compared to inflow streams (midsummer …

Ecology And Management Of A High Elevation Southern Range Greater Sage-Grouse Population: Vegetation Manipulation, Early Chick Survival, And Hunter Motivations, Michael R. Guttery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My research provided new information concerning the management, ecology, and conservation of greater sage-grouse (Centrocercus urophasianus). I report the results of an experiment using strategic intensive sheep grazing to enhance the quality of greater sage-grouse brood-rearing habitat. Although forb cover, an important component of brood-rearing habitat, responded positively to the grazing treatment, the response of other habitat variables was suppressed because the plots were not protected from domestic and wild herbivores during the years following the treatments. Measurements taken in grazing exclosures confirmed that herbivory by both large and small animals had significant impacts on vegetation. However, despite …

Young's Schema Theory: Exploring The Direct And Indirect Links Between Negative Childhood Experiences And Temperament To Negative Affectivity In Adulthood, Mark S. Jesinoski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Young's schema theory offers a theoretical approach that relates negative childhood experiences, temperament, and early maladaptive schema, to the experience of negative affect and/or depression in adulthood. However, despite the widespread use of schema therapy in clinical practice, little research has explored the pathways theorized by Young. This study explored the pathways posited by Young and colleagues looking at the direct and indirect relationships among negative childhood experience, temperament, early maladaptive schema, and the experience of negative affect in adulthood. Self-report data were collected from 365 undergraduate students. Results demonstrated consistent and robust direct relationships between temperament and negative affect, …

Historical Biogeography Of Velvet Ants (Hymenoptera: Mutillidae) In The North American Deserts And Arid Lands, Joseph S. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For centuries, scientists have been intrigued by the high amount of biodiversity that is found in the deserts of North America. Recently, several studies have investigated the causes of the high diversity found in desert-dwelling mammals, reptiles, and amphibians. These studies have found that many of these organisms seem to have diversified in response to the same historical events. Little work has been done, however, on diverse desert-dwelling insect groups. In this dissertation, I investigate the patterns of genetic diversity in four groups of nocturnal wasps called velvet ants. I compare the patterns of genetic diversity to the historical events …

Spatial Light Dilution As A Technique For Conversion Of Solar Energy To Algal Biomass, Daniel J. Dye

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A photobioreactor has been designed and developed to efficiently utilize solar irradiance through spatial dilution of sunlight. The concept of spatial light dilution is simple: incident sunlight is spread over a large surface area, thus reducing the photon flux density of the light. The implementation of this technique, however, is difficult. The reactor described within uses a new approach to spatial light dilution, utilizing recently-developed optical components to diffuse concentrated sunlight inside an algae culture. Preliminary productivity tests indicate a 2-3 fold increase in productivity per unit aperture (sunlight collection area) over a control reactor with direct-sunlight. Aperture productivity of …

Kinetic, Mechanistic, And Structural Investigation Of Features Controlling Stereoselectivity Of (R)- And (S)-Hydroxypropyl Com Dehydrogenases From Xanthobacter Autrophicus Strain Py2, Dariusz Adam Sliwa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enantiopure alcohols are valuable intermediates in fine organic synthesis, in particular for preparation of biologically active compounds. The necessity of preparing single enantiomer drugs in an optically pure form has triggered much research, especially in the pharmaceutical industry. The biocatalytical production of chiral alcohols by alcohol dehydrogenase enzymes is characterized by the asymmetric reduction of the corresponding ketones, usually with high degree of stereoselectivity. The commercial value of the enzymes as stereoselective biocatalysts has been a significant driving force in understanding features that control their mechanism of catalysis and stereoselectivity. This work focuses on two enantiocomplementary dehydrogenase enzymes ((R …

Clarifying The Relationship Between Emotion Regulation, Gender, And Depression, Emi Sumida

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigates the relation between emotion regulation problems and clinical depression. One goal of the present study was to bring increased clarity and parsimony to how emotion regulation is presently measured by consolidating three widely used instruments. In addition, of interest was an investigation of whether particular emotion regulation problems and management strategies interact with gender to predict either severity of overall depression symptoms or the presence of a formal mood disorder diagnosis. The results clearly showed that irrespective of a person's gender, particular emotion regulation indicators, both singly, and in combination, are, indeed, more strongly related to the …

The State Of Integrated Open Space Planning: Toward Landscape Integrity?, Lindsay Ex

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Open space planning has been present within the United States for over a century. Traditionally, open space planning efforts tend to focus more exclusively on either socially-based (e.g., recreational, scenic, or park planning) or ecologically-based (e.g., preserves, habitat networks or more general conservation planning) planning efforts. This separation of ecological and social frameworks in open space planning is reinforced by a persistent cultural model, where community and conservation are seen as opposing forces instead of partners.

While recent open space planning efforts have begun to integrate social and ecological frameworks into one plan, the majority of our knowledge on integrated …

Bosom Buddies: Factors Associated With Experiences Of Passionate Friendship Among Men And Women, Katherine A. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Scholars historically have separated friendships and romantic relationships into two qualitatively distinct relationship categories. Contemporary research examining passionate friendships, however, has identified qualities within platonic relationships that appear to mimic characteristics typically associated with romantic relationships. Primary critiques of the existing passionate friendship literature include exclusively examining females, including samples that predominately identified as lesbian, bisexual or questioning, and research utilizing solely qualitative designs.

The current study used a quantitative design to investigate 375 emerging adults' (18-26 years of age; 149 males, 226 females) friendship experiences. Specifically, four quasi-independent variables (i.e., biological sex, sexual orientation, gender-role orientation, and cross vs. …

The Essential Structure Of Compulsive Buying: A Phenomenological Inquiry, Letty Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

While many jokes and sales of specialty merchandise have been made that make light of consumers who frequently shop and buy (e.g., "When the going gets tough, the tough go shopping," or "I am a shopaholic"), for 18 million Americans suffering from compulsive buying, the process of shopping and buying has caused their lives to literally go out of control. The outcomes of this disease for individuals, families, and business are all negative. In a marketing era of social responsibility, if marketers either knowingly or unknowingly encourage increased consumption among compulsive buyers, potential negative outcomes stand to impact others well …

Integration Of Ultrasonic Consolidation And Direct-Write To Fabricate An Embedded Electrical System Within A Metallic Enclosure, Ludwing A. Hernandez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A research project was undertaken to integrate Ultrasonic Consolitation (UC) and Direct-Write (DW) technologies into a single apparatus to fabricate embedded electrical systems within an ultrasonically consolidated metallic enclosure. Process and design guidelines were developed after performing fundamental research on the operational capabilities of the implemented system. In order to develop such guidelines, numerous tests were performed on both UC and DW. The results from those tests, as well as the design and process guidelines for the fabrication of an embedded touch switch, can be used as a base for future research and experimentation on the UC-DW apparatus. The successful …

Finances In Strong African American Marriages, Bonnie Lichfield Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study focused on how African American couples in happy marriages talked about finances in their couple relationships. Qualitative methodology was used for this study, and the data came from transcribed interviews with participants. Thirty-seven couples who identified their marriages as being strong, happy, or highly satisfying, volunteered to be interviewed for this study. All individual participants (74 total) talked about finances in their marriages, and all interviews were used for the purpose of this study. Their descriptions were coded and analyzed to explore the way that they talked about money issues in their marriages. The research questions focused on …

Environmental And Developmental Indicators In Early Childhood: Relations To Second-Grade Reading Comprehension, Gina A. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reading success has been linked to high school completion, future job success, and future generations of children who can read. Unfortunately, children who are unable to read on grade level by the end of first grade are at a great disadvantage and unlikely to catch up later. Without the ability to read and comprehend text, all aspects of schooling become progressively more difficult and the challenge of poor reading ability can be so difficult to overcome that many poor readers will not complete high school. For these reasons, it is important to identify early experiences in a child's family environment …

Native Bunchgrass And Invasive Weed Establishment In Low Nutrient Rangeland Soils With Nitrogen And Phosphorus Manipulation, Jeffrey S. Burnham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Competition between native perennial grasses and Bromus tectorum has been studied for many years. Recently, soil nutrients have been immobilized in an effort to preferentially inhibit growth of B. tectorum relative to native species. Most of this work has focused on soil N, but interactions with soil P are less studied and may be important as well. Additionally, although competitive effects and nutrient responses of several Centaurea spp. are well documented, data are lacking on the competitive effects that Centaurea virgata exerts on the establishment of native and exotic communities. A field experiment and a greenhouse experiment were conducted to …

Back Where They Once Belonged? Local Response To Afforestation In County Kerry, Ireland, Matthew S. Carroll, Áine Ní Dhubháin, Courtney G. Flint

Sociology, Social Work and Anthropology Faculty Publications

Afforestation has many benefits at the local regional and global scale. The local social impacts of planting new forests, however, depend on a variety of contextual factors and other details including who is doing the planting, which species are being planted, the location of the planting and, perhaps most importantly, existing land uses and their linkage to social and economic circumstances. This article presents case study research into these issues in two places in County Kerry Ireland. Utilising the concept of the differentiated landscape, we examine the somewhat varying social responses to afforestation in the two study sites in light …

Predator Functional Response Changed By Induced Defenses In Prey, Edd Hammill, Owen L. Petchey, Bradley R. Anholt

Watershed Sciences Faculty Publications

Functional responses play a central role in the nature and stability of predator‐prey population dynamics. Here we investigate how induced defenses affect predator functional responses. In experimental communities, prey (Paramecium) expressed two previously undocumented inducible defenses—a speed reduction and a width increase—in response to nonlethal exposure to predatory Stenostomum. Nonlethal exposure also changed the shape of the predator’s functional response from Type II to Type III, consistent with changes in the density dependence of attack rates. Handling times were also affected by prey defenses, increasing at least sixfold. These changes show that induced changes in prey have a real defensive …
