Geographic Variation In The Genetic Basis Of Resistance To Leaf Rust Between Locally Adapted Ecotypes Of The Biofuel Crop Switchgrass (Panicum Virgatum), Acer Van Wallendael, Jason Bonnette, Thomas E. Juenger, Felix B. Fritschi, Philip A. Fay, Robert B. Mitchell, John Lloyd-Reilley, Francis M. Rouquette Jr, Gary C. Bergstrom, David B. Lowry

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Local adaptation is an important process in plant evolution, which can be impacted by differential pathogen pressures along environmental gradients. However, the degree to which pathogen resistance loci vary in effect across space and time is incompletely described.

To understand how the genetic architecture of resistance varies across time and geographic space, we quantified rust (Puccinia spp.) severity in switchgrass (Panicum virgatum) plantings at eight locations across the central USA for 3 yr and conducted quantitative trait locus (QTL) mapping for rust progression.

We mapped several variable QTLs, but two large-effect QTLs which we have named Prr1 and Prr2 were …

Elemental Climate Disaster Texts And Queer Ecological Temporality, Laura Mattson

USF Tampa Graduate Theses and Dissertations

This thesis approaches climate disaster texts as an opportunity to challenge constructions of the body, space, and time. Developed from embodied experiential knowledge about hurricanes, my work will explore how climate disasters can teach us to reimagine human-nature relationships. In my two analysis chapters, I use critical textual analysis and autoethnography to challenge particular representations of the human-nature relationship as a binary between nature and culture. By intervening in the nature-culture binary, I theorize queer ecological temporality as an opportunity to reveal and challenge constructions of nature and time. Working at the intersections of queer and ecocritical theory, this thesis …

Detecting Geomorphic Change And Stream Channel Evolution On The Sandy River, Oregon, Using Lidar Following Dam Removal In 2007, Lowell Henry Anthony

Dissertations and Theses

Following the removal of Marmot Dam on the Sandy River, Oregon, several Lidar flights were flown over the area of the former reservoir. The resultant sequential DEMs permitted calculation of reach-scale volumetric erosion and aggradation following dam removal. This allows for change detection across the entire affected reach of the former impoundment rather than just at several cross sections. In the first year there was a net loss of blank sediment in the dewatered reach. Subsequent flights show continued degradation of 145,649 m³ as well as aggradation of 6,232 m³. Sediment transport reached quasi-equilibrium in 2012 with …

Essays On Mortgage Portfolio Diversification, Timothy Patrick Dombrowski

LSU Doctoral Dissertations

Portfolios of mortgage loans played an important role in the Great Recession and continue to compose a material part of bank assets. The distribution of mortgage portfolio returns, and consequently, the risk of these portfolios, is quite distinct even from other fixed income asset classes. This dissertation contains three essays, each aiming to analyze a specific component of risk in mortgage portfolios and role of geographical diversification in reducing this risk.

The first essay investigates how cross-sectional dependence in the underlying properties flows through to the loan returns, and thus, the risk of the portfolio. In addition to demonstrating this …

Life Satisfaction In Division Iaa And Division Iii Football Players, Krista Haunani Francisco

Dissertations and Theses

Level of life satisfaction is not something of which many sit down and take appraisal. However, levels of life satisfaction, especially low levels of life satisfaction, can have a direct effect on health. Low levels of life satisfaction cause an increase in self-reported stress. Inversely, high levels of stress cause a decrease in life satisfaction. This decrease in life satisfaction is associated with poor mental and physical health outcomes. A majority of student-athlete healthcare is centered around the physical aspects of health, with mental health just recently becoming a concern. It was apparent through the research for this study that …

How Do Student Nurses Of English Language Learner Populations Experience Nclex-Rn Style Questions?, Shawne Manies

Dissertations

The purpose of this qualitative study was to explore how student nurses of English Language Learner (ELL) populations experienced National Council Licensure Examination for Registered Nurses (NCLEX-RN) style questions. Evidence has suggested difficulty in improving the nation’s diversified nursing workforce, resulting in concerns over minority nurse representation. Student nurses of ELL populations are more likely than non-English language learner student nurses to be out of sequence or released from a nursing program. The extant literature has shown that this population of students struggle with NCLEX-RN style questions and that they have significantly lower pass rates than their English-speaking counterparts. Literature …

Carnivore Population Structure Across An Urbanization Gradient: A Regional Genetic Analysis Of Bobcats In Southern California, Julia G. Smith, Megan K. Jennings, Erin E. Boydston, Kevin R. Crooks, Holly B. Ernest, Seth Riley, Laurel E. K. Serleys, Shaelynn Sleater-Squires, Rebecca L. Lewison

United States National Park Service: Publications

Context In human-dominated landscapes, habitat fragmentation and barriers to movement can interrupt gene flow. While often considered at a local extent, regional analyses are also needed to reveal broader landscape-mediated population processes.

Objectives To explore the relationship between patterns of gene flow and fragmentation resulting from urbanization across southern California, we used the bobcat as an indicator species. We assembled data for a landscape level genetic analysis across southern California from both archived and new samples, including two northern Californian populations for comparison, to identify local and regional areas affected by isolation.

Methods Our regional analyses focused on a dataset …

Species Composition And Hybridization Among Native And Nonnative Catostomid Fishes In Two Streams Of The Gunnison River Basin, Colorado, Michael R. Schwemm, Kevin G. Thompson, Evan W. Carson, Megan J. Osborne, Thomas F. Turner

Western North American Naturalist

We report results from a 3-year field investigation to limit hybridization between native and nonnative suckers in 2 small tributaries of the Gunnison River basin, Delta County, Colorado. Upstream movement to spawning habitat was selectively impeded by picket weir in intermittent Cottonwood Creek. There, native suckers were identified based on morphological characters in the field and were transferred upstream of the weir, whereas nonnative fishes were excluded from upstream movement. Another stream, Potter Creek, was not impeded by weir. Genetic identification of adult fishes in both streams was consistent with morphological identification in the field. Larval genetic identification was consistent …

Exporting Consumption: Lifestyle Migration And Energy Use, Richelle Winkler, David Matarrita-Cascante

Michigan Tech Publications, Part 1

This paper examines how international population movements from highly developed to less developed countries spread environmentally-impactful consumption habits around the world. Lifestyle migration, a phenomenon whereby relatively privileged migrants move in search of a more fulfilling life, is increasingly common around the world and serves as an optimal example for studying the spread of unsustainable consumption. We wonder whether lifestyle migrants take high consumption lifestyles typical in their countries of origin to their destination places and whether their presence in destination communities increases consumption among natives as well. This study investigates these relationships based on the case of Costa Rica, …

Survey Of Latino/Hispanic Adult Immigrants Living In The Colonias Of Hidalgo County, Texas Evaluating Reported Food Insecurity And Immigration-Related Fear, Julia Rosenberg, Sindhu Sudanagunta, Marsha Griffin

Journal of Applied Research on Children: Informing Policy for Children at Risk

Background:

Colonias in Hidalgo County, Texas are residential communities near the Texas-Mexico border which often lack basic living necessities with high rates of poverty. Due to complex socioeconomic/geopolitical stressors (factors ranging from income inequality to access to transportation to concern regarding safety and legal status), colonia residents have limited access to fresh produce, while processed foods are more readily available, resulting in significant food insecurity.

Objectives:

The aim of this study is to assess levels of food insecurity, current eating habits, barriers of access, and interest in more readily affordable and accessible produce options in colonias of Hidalgo County, Texas. …

Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors

United States National Park Service: Publications

Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 percent of 1–3 anthropogenic carbon dioxide emissions. Climate-driven vegetation models 4,5 typically predict that this tropical forest ‘carbon sink’ will continue for decades . Here we assess trends in the carbon sink using 244 structurally intact African tropical forests spanning 11 countries, compare them with 321 published plots from Amazonia and investigate the underlying drivers of the trends. The carbon sink in live aboveground biomass in intact African tropical forests has been stable for the three decades to …

The Weave Of Youth Writing: Refiguring Authorship And Self-Representation In Michaela Deprince’S Collaborative Archive Of Life Narrative Texts, Alberta Natasia Adji

Research outputs 2014 to 2021

Young people have to struggle in navigating the complex cultural and socio-political frameworks of production if they would like to reclaim agency and legitimacy to voice their aspirations. This article focuses on questions of authorship and self-representation in both the traditional and digital life writing texts created by and produced for Sierra-Leonean-American ballet dancer Michaela DePrince, which turns out to be highly mediated by her Jewish Caucasian adoptive mother Elaine DePrince. I argue that the manners of Michaela’s collaborative archive of life narrative projects–which bring about issues of authorship–have conformed her self-representation to particular identity frames in terms of race, …

Dedication To Tagore By Mustafo Bafoev (On The Problem Of Studying Composer's Creativity In The Context Of Monodial Thinking), Alina Kutluchurina

Eurasian music science journal

This article focuses on the problem of understanding the Uzbek composer's creativity of the last decades in the context of monodies (national) thinking. The traditional Uzbek monody, represented by such high genres of the intangible cultural heritage of mankind as Ashula, Biga Ashula, makoms, and modern composer's creativity, are two self-developing areas carrying the idea of coexistence and interaction. Presenting a complex and poorly researched area of modern music science, monody is understood not as a type of warehouse (facture), but as a type of thinking, first systematized by the researcher S.P. Galitsa in the work "Theoretical issues of monody". …

Long-Term Variations (2001-2016) Of Satellite-Based Pm2.5 Concentrations And Its Determinants In Xinjiang, Northwest Of China, Wei Wang, Alim Samat, Jilili Abuduwaili

Karakalpak Scientific Journal

Based on the long-term series of satellite-retrieved PM2.5 concentrations, this study explored the spatiotemporal variation and aggregation characteristics of PM2.5 concentrations in Xinjiang from 2001 to 2016 by using standard deviational ellipse analysis and spatial autocorrelation statistics method. The result showed that the annual average PM2.5 concentrations was high in the north slope of Tianshan mountain and the western Tarim desert where High-High clusters mainly distribute. Furthermore, PM2.5 concentrations in the north slope of Tianshan mountain increased significantly from 2001 to 2016. Based on the result of GeoDetector model, population density was the most dominant factor of PM2.5 concentrations (q=0.55). …

School-Based Agricultural Education Students’ Attitudes And Beliefs Toward International Agricultural Concepts, Seth B. Heinert, Nathan W. Conner, T. Grady Roberts

Journal of Human Sciences and Extension

The purpose of this study was to determine the attitudes and beliefs of school-based agriculture education (SBAE) students toward international agricultural concepts. This study builds on several previous studies (Conner, Greer, & Stripling, 2017; Elliot & Yanik, 2002; Heinert, Lavery, & Roberts, 2014; Radhakrishna, Leite, & Domer, 2003). To explore new geographic regions of the United States, two states, one from the Midwest and one from the Northwest, were purposively identified. A 46-item instrument that measures attitudes, beliefs, understanding, and instruction in relation to international agriculture developed by Radhakrishna et al. (2003) was administered to students in three schools representing …

Farming Along Desire Lines: Collective Action And Food Systems Adaptation To Climate Change., Thomas F. Thornton, B. Soubry, K. Sherren

Faculty, Staff, and Students

1. We examine collective action in the food system of the Canadian Maritimes to determine its effect on the resilience and adaptive capacity of food producers, distributors, retailers and governance institutions. 2. Our data suggest that beyond their immediate benefits for their participants, expressions of collective action generate higher-level impacts which often translate into drivers of adaptive capacity. 3. Drawing on a metaphor from urban design, we suggest that collective action should be considered a desire line for food systems adaptation: rather than building adaptation strategies based on top-down design, collective action emerges from farmers’ needs and capacities to build …

Distributions Of Eastern And Western Red Bats In Western North America, Donald I. Solick, Robert M.R. Barclay, Larisa Bishop-Boros, Quentin R. Hays, Cori L. Lausen

Western North American Naturalist

The known distributions of eastern red bats and western red bats in western North America have changed greatly over the past 2 decades, resulting in inaccurate range maps and uncertainty regarding the presence or probable absence of these species within states and provinces. We obtained capture and specimen records from the western United States and Canada for 276 eastern red bats and for 863 western red bats. We documented the expansion of the range of eastern red bats in northwestern Canada and clarified the northern and eastern limits of western red bat distribution in the United States. We found that …
