  • Investigations of the AhR-induced Treg : transcriptional regulation and suppressive mechanisms

    Creator:
    Rohlman, Diana
    Abstract:
    The aryl hydrocarbon receptor (AhR) has recently been described as a novel therapeutic target, given the potent suppression of multiple immune-mediated diseases following activation by the prototypic ligand, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). In the parent-into-F1 graft-versus-host (GVH) model, suppression of the cytotoxic T-lymphocyte (CTL) response is associated with the presence of CD25⁺CTLA-4⁺IL-10⁺Foxp3[superscript...

  • Enhancing social-ecological resilience in the Colorado River Basin

    Creator:
    Eidem, Nathan T.
    Abstract:
    This research presents the Colorado River basin as a social-ecological system. Utilizing event data on cooperative and conflictive interactions over fresh water, the system is decomposed to look for evidence of outcomes of resilience enhancement. The Animas-La Plata Project in the upper San Juan basin is presented as a case...

  • Towards an Integrated Decision Tool for Managing Wildlife with Visitor Restrictions in Glacier Bay National Park

    Creator:
    Whitlock, Steven L.
    Abstract:
    The National Park Service has a dual mission of providing public access to exceptional natural resources, but in a manner such that these resources are left “unimpaired for the enjoyment of future generations.” Human activities in parks undoubtedly affect wildlife, but the degree to which such activities cause impairment is...

  • West Nile virus : forecasting models for a resurging vector-borne disease in Arizona, U.S.A.

    Creator:
    Roldan, Josiah Javier
    Abstract:
    West Nile Virus (WNV), a vector-borne disease continues to be a serious threat to public health in the United States, particularly in the Southwest region. While all the states in the U.S. experienced a decreasing trend of WNV disease in 2010, the state of Arizona experienced a sharp increase from...

  • Functionalization of carbon nanotubes for effective biosensing and potential biomedical applications

    Creator:
    Adenuga, Adeniyi A.
    Abstract:
    Since their discovery in the 1990s, the great potential of carbon nanotubes (CNTs) has made them a focus of many research endeavors, including their application as components of biosensors. The inherent chemical "inertness" of CNTs makes their application to biosensing a challenge. It is necessary to "decorate" their surfaces to...

  • Reproductive implications of parasitic infections and immune challenges in garter snakes

    Creator:
    Uhrig, Emily J.
    Abstract:
    Parasitic infections and immune challenges can affect host reproductive fitness and, ultimately, the evolution of host populations in a myriad of ways. The fitness implications of parasitic infections range from increased host mortality to subtle changes in reproductive investment. From alterations of behaviors, sexual signaling, and competitive ability to changes...

  • Societal Responses to Using Genetic Engineering for Mitigating Chestnut Blight and Restoring American Chestnut Trees

    Creator:
    Petit, Joshua D.
    Abstract:
    Forests face health threats from pests and diseases (e.g., mountain pine beetle, emerald ash borer, chestnut blight [CB], Swiss needle cast), and other issues such as climate change. Interventions such as genetic engineering (GE) have shown promise for mitigating some of these threats. CB, for example, has impacted most American...

  • Metal Oxide Cluster Chemistries for Next Generation Nanomanufacturing

    Creator:
    Frederick, Ryan T.
    Abstract:
    Metal oxide clusters are promising inorganic photoresists in next generation nanomanufacturing because of their potential for high-resolution and low line-edge roughness patterning, and exceptional sensitivity to extreme ultraviolet (EUV) radiation. In EUV patterning, absorption of EUV radiation leads to electron emission that serve as a primary species for driving radiation...

  • Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

    Creator:
    Kavanaugh, Maria T.
    Abstract:
    Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

  • Jumping in with Both Feet: Exploring Factors that Shape Juvenile Amphibian Movement

    Creator:
    Bredeweg, Evan M.
    Abstract:
    Investigation into how animals move within the landscape is important for both understanding of ecological processes and conservation management. Animal movement is important in shaping life history transitions, demographics, individual fitness, and species distributions. However, as landscapes become increasingly affected by human activities, movement becomes important as species navigate landscapes...
