Plant Endemism And Geoendemic Areas Of Utah, Stanley L. Welsh, Nephi Duane Atwood

Books by Faculty of the Monte L. Bean Life Science Museum

Abstract

This summary of Utah's plant endemics is based large part on a paper dealing with differences and similarities of the Great Basin and Colorado Plateau presented by Welsh to a meeting of the Range Society of America at Montrose, Colorado, in May of 2004, and a second presentation to the Colorado Native Plant Society in September of 2007. Discussed in those presentations were brief considerations of topography and geomorphology, geology, hydrology, vegetation, migrational aspects, endemics and disjuncts, and peculiar habitats of plants in the Great Basin of Utah and in the Colorado Plateau. This work expands on those considerations …

Categorical Change: Exploring The Effects Of Concept Drift In Human Perceptual Category Learning, Andrew Wismer

Electronic Theses and Dissertations

Categorization is an essential survival skill that we engage in daily. A multitude of behavioral and neuropsychological evidence support the existence of multiple learning systems involved in category learning. COmpetition between Verbal and Implicit Systems (COVIS) theory provides a neuropsychological basis for the existence of an explicit and implicit learning system involved in the learning of category rules. COVIS provides a convincing account of asymptotic performance in human category learning. However, COVIS – and virtually all current theories of category learning – focus solely on categories and decision environments that remain stationary over time. However, our environment is dynamic, and …

Unearthing The Past And Present Of A Semi-Fossorial Lizard: Conservation Genetics, Phylogeography, And Taxonomy Of Plestiodon Egregius., Kathryn Mercier

Electronic Theses and Dissertations

Characterizing an organism's evolutionary history and population structure as well as understanding the forces shaping that divergence is crucial to conservation biology. A clear understanding of the patterns of diversity and divergence are imperative for the best management of the organism, while an awareness of what drives these patterns can lead to better predictions of how organisms will respond to future climate change. Historical climate changes and associated sea level change are among the main forces driving divergence in many species. To examine how effects of climate changes may have driven patterns of intraspecific divergence, I examined Mole Skinks, Plestiodon …

Student Led Campus Desire Path Evaluation Using Pictometry® Neighborhood Imagery, David Kulhavy, Daniel Unger, I-Kuai Hung

Faculty Publications

A student led evaluation of desire paths (e.g., paths created by pedestrians on an open landscape) across the Stephen F. Austin State University (SFASU) campus was performed within a senior level spatial science course in order to create a method for mitigation of desire paths and for campus beautification. Each desire path on campus was identified with the length of each path measured in the field and categorized by the condition of the path in order to assess and determine a necessary solution for each path identified. In addition, Pictometry^® high spatial resolution digital imagery was used to determine …

Food Habits Of Sympatric Pitvipers From The West Gulf Coastal Plain, Usa, Christopher M. Schalk, Toni Trees, Joshua B. Pierce, D. Craig Rudolph

Faculty Publications

Widespread species that occupy multiple communities exhibit geographic variation in their natural history due to the ecological context of the local community. An animal’s food habitats are a central component to understanding its natural history and ecological role within its community—information that is critical to understanding resource needs of a species, mechanisms of species coexistence, and energy flow in food webs (Litvaitis 2000; Schalk et al. 2014). This information is also crucial for predicting the response of populations to changes in resource availability and, if necessary, inform mitigation strategies (Holycross and Mackessy 2002)

Preliminary Studies On Immune Response And Viral Pathogenesis Of Zika Virus In Rhesus Macaques, Shawna M. Woollard, Omalla A. Olwenyi, Debashis Dutta, Rajnish S. Dave, Saumi Mathews, Santhi Gorantla, Noel Johnson, Luis Giavedoni, Robert B. Norgren, Siddappa N. Byrareddy

Journal Articles: Genetics, Cell Biology & Anatomy

Zika Virus (ZIKV) is primarily transmitted through mosquito bites. It can also be transmitted during sexual intercourse and in utero from mother to fetus. To gain preliminary insight into ZIKV pathology and immune responses on route of transmission, rhesus macaques (RMs) were inoculated with ZIKV (PRVABC59) via intravaginal (IVAG) (n = 3) or subcutaneous (sub Q) (n = 2) routes. Systemic ZIKV infection was observed in all RMs, regardless of the route of inoculation. After 9 days postinfection (dpi), ZIKV was not detected in the plasma of IVAG- and sub-Q-inoculated RMs. Importantly, RMs harbored ZIKV up to 60 …

Effects Of Cold Acclimation On Rectal Macromorphology, Ultrastructure, And Cytoskeletal Stability In Gryllus Pennsylvanicus Crickets., Lauren E Des Marteaux, Joseph R Stinziano, Brent J Sinclair

Biology Publications

Cold-acclimated insects maintain ion and water balance in the cold, potentially by reducing permeability or increasing diffusion distance across ionoregulatory epithelia such as the rectum. We explored whether cold acclimation induces structural modifications that minimize water and ion diffusion across the rectum and maintain rectal cell integrity. We investigated rectal structure and cytoskeletal stability in chill-susceptible adult Gryllus pennsylvanicus crickets acclimated for one week to either warm (25 °C) or cold (12 °C) conditions. After acclimation, we used light and transmission electron microscopy to examine rectal macromorphology and rectal pad paracellular ultrastructure. We also used fluorescence microscopy and a filamentous-actin …

Seasonal Shifts In The Insect Gut Microbiome Are Concurrent With Changes In Cold Tolerance And Immunity, Laura V. Ferguson, Pranav Dhakal, Jacqueline E. Lebenzon, David E. Heinrichs, Carol Bucking, Brent Sinclair

Biology Publications

1. Seasonal changes in the environment, such as varying temperature, have the potential to change the functional relationship between ectothermic animals, such as insects, and their microbiomes. Our objectives were to determine: (a) whether seasonal changes in temperature shift the composition of the insect gut microbiome, and (b) whether changes in the microbiome are concomitant with changes in the physiology of the host, including the immune system and response to cold.
2. We exposed laboratory populations of the spring field cricket, Gryllus veletis (Orthoptera: Gryllidae), to simulated overwintering conditions in both a laboratory microcosm and a field‐like microcosm containing soil and leaves. …

Uncovering The Neural Basis Of Cognitive Impairment Following Hearing Loss: An All-Optical Electrophysiology Approach, Brainscan, Western University, Brian Allman, Wataru Inoue

Project Summaries

We have access to state-of-the-art equipment that will enable us to visualize specific neuron types in animal models. This is a new approach that combines several recent advances in the field of 'optogenetics', a technique that uses light to control neurons. This approach will allow us to explore how hearing loss induced by loud noise exposure leads to abnormal neural activity in areas of the brain that control learning, memory and higher cognitive function.

Polymer Assembly Encapsulation Of Lanthanide Nanoparticles As Contrast Agents For In Vivo Micro-Ct, Charmainne Cruje, Joy Dunmore-Buyze, Jarret P. Macdonald, David W. Holdsworth, Maria Drangova, Elizabeth R. Gillies

Chemistry Publications

Despite recent technological advancements in microcomputed tomography (micro-CT) and contrast agent development, pre-clinical contrast agents are still predominantly iodine-based. Higher contrast can be achieved when using elements with higher atomic numbers, such as lanthanides; lanthanides also have x-ray attenuation properties that are ideal for spectral CT. However, the formulation of lanthanide-based contrast agents at the high concentrations required for vascular imaging presents a significant challenge. In this work, we developed an erbium-based contrast agent that meets micro-CT imaging requirements, which include colloidal stability upon redispersion at high concentrations, evasion of rapid renal clearance, and circulation times of tens of minutes …

South Asian American Visual Culture And Representation, Bakirathi Mani

English Literature Faculty Works

South Asian American visual culture is a diverse field of visual art, created by artists who are first-, second- and third-generation immigrants from Pakistan, India, and Bangladesh, among other diasporic locations (e.g., Kenya). South Asian American artists work in a range of media forms, including photography, sculpture, installation, video, painting, and drawing. Collectively, these artworks are frequently exhibited in museums and galleries as depictions of contemporary South Asian immigrant life. However, a close reading of individual works produces a more dynamic picture. Instead of viewing South Asian American visual culture solely in terms of artists’ own immigrant biographies, scholarship and …

Resilience Thinking For Peacebuilders, Patrik Johansson

International Journal of Peace Studies

The concept of resilience is currently making its way into the field of peace and conflict studies, but it is a concept with different meanings and implications. The argument advanced in this paper is that in order to make the most of resilience thinking, the field should not conceive of resilience merely as the ability to bounce back to an original state after a disturbance, a conceptualization usually referred to as “engineering resilience.” Instead, it should engage with “ecological resilience,” which refers to the amount of disturbance that a system can absorb before being pushed across a threshold from one …

Risky Pay And The Financial Crisis: Who's Responsible?, Jeffrey Moriarty

Philosophy Faculty Publications

According to an existing “environmental” narrative, the financial crisis of 2007-2009 was due in part to executive compensation packages in the financial services industry that incentivized excessive risk-taking. Also according to this narrative, those who have a duty to protect society – principally, government regulators, but also firms themselves – are open to blame for how executives were paid, and must take steps to change executive compensation. This narrative is important but incomplete. I offer a supplementary “agential” narrative. According to this narrative, executives are open to blame for the financial crisis for taking socially excessive risks. Moreover, since executives …

Triangulating Abuse Liability Assessment For Flavoured Cigar Products Using Physiological, Behavioural Economic And Subjective Assessments: A Within-Subjects Clinical Laboratory Protocol, Catherine S. Wall, Rose S. Bono, Rebecca C. Lester, Cosima Hoetger, Thokozeni Lipato, Mignonne C. Guy, Thomas E. Eissenberg, Warren K. Bickel, Andrew J. Barnes, Caroline O. Cobb

Health Policy Publications

Introduction
In the USA, Food and Drug Administration regulations prohibit the sale of flavoured cigarettes, with menthol being the exception. However, the manufacture, advertisement and sale of flavoured cigar products are permitted. Such flavourings influence positive perceptions of tobacco products and are linked to increased use. Flavourings may mask the taste of tobacco and enhance smoke inhalation, influencing toxicant exposure and abuse liability among novice tobacco users. Using clinical laboratory methods, this study investigates how flavour availability affects measures of abuse liability in young adult cigarette smokers. The specific aims are to evaluate the effect of cigar flavours on nicotine …

On-Road Emissions Of Ammonia: An Underappreciated Source Of Atmospheric Nitrogen Deposition, Mark E. Fenn, Andrzej Bytnerowicz, Susan L. Schilling, Dena M. Vallano, Erika S. Zavaleta, Stuart B. Weiss, Connor Morozumi, Linda H. Geiser, Kenneth Hanks

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

We provide updated spatial distribution and inventory data for on-road NH₃ emissions for the continental United States (U.S.) On-road NH₃ emissions were determined from on-road CO₂ emissions data and empirical NH₃:CO₂ vehicle emissions ratios. Emissions of NH₃ from on-road sources in urbanized regions are typically 0.1– 1.3 t km⁻² yr⁻¹ while NH₃ emissions in agricultural regions generally range from 0.4–5.5 t km⁻² yr⁻¹, with a few hot spots as high as 5.5–11.2 t km⁻² yr⁻¹. Counties with higher vehicle NH3 emissions than from agriculture …
