  • Investigating variation in immunity and infection risk in wild ungulates

    Creator:
    Dugovich, Brian S.
    Abstract:
    In the midst of the sixth mass extinction, understanding wildlife disease spillover is critical to maintaining protected wildlife areas. Studying ecoimmunology and wildlife disease ecology helps to understand immune and disease traits in an ecological context, which is invaluable in preventing pathogen spillover between livestock and wildlife. To investigate this...

  • Identification and characterization of vasotocin and mesotocin peptides and receptors

    Creator:
    Searcy, Brian T.
    Abstract:
    The neurohypophysial peptide system is involved in modulating a variety of physiological, neurological, and behavioral responses in vertebrates. The principal forms of these peptides in non-mammalian tetrapods are vasotocin (VT) and mesotocin (MT). The studies described in this thesis used pharmacological, molecular, and biochemical techniques, along with phylogenetic analyses, to...

  • Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

    Creator:
    Tanis, Brian P.
    Abstract:
    The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

  • The role of the vertebral column during jumping in quadrupedal mammals

    Creator:
    Harty, Tyson H.
    Abstract:
    Little, if any, quantifications have been made on the contribution of the vertebral column during jumping in quadrupedal mammals. Previous studies of jumpers have focused on the morphological and physiological specializations of the hindlimbs. In this study, such specialization was measured during the supramaximal jumps of the Pacific jumping mouse...

  • Thermal Tolerance and Adaptation in Cnidarians: An Investigation of Host Transcriptomic Responses and Heritable Variation Across Natural Populations

    Creator:
    Dziedzic, Katherine E.
    Abstract:
    Coral reefs have become vulnerable to climate change, with mass bleaching events, the loss of symbiotic algae (Symbiodiniaceae), increasing in both frequency and severity. As climate change continues to threaten the persistence and existence of coral reefs around the world, the biggest question posed for coral reefs is “can they...

  • New perspectives in archosaur biology

    Creator:
    Harwell, Amy E.
    Abstract:
    The respiratory and metabolic biology of dinosaurs is poorly, if at all, reflected in the fossil record. By comparing anatomical features of modern taxa that are functionally linked to specific biology with the remains of theropod dinosaurs (Archosauria: Theropoda) and early birds, we may reasonably infer the physiology of long...

  • Linking marine communities and ecosystems : invertebrates mediate nutrient availability in intertidal communities

    Creator:
    Bracken, Matthew E.
    Abstract:
    While community ecologists have traditionally focused on local-scale processes, it has become apparent that a broader perspective, which explores the community-level ramifications of material fluxes within and between ecosystems, is necessary to effectively evaluate bottom-up influences on community structure and dynamics. In this dissertation, I employed ecosystem principles to understand...

  • Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

    Creator:
    Coblentz, Kyle E.
    Abstract:
    Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

  • Temperature stress, gene expression, and innate immunity at the onset of cnidarian-dinoflagellate symbiosis

    Creator:
    Schnitzler, Christine E.
    Abstract:
    The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...

  • Neuronal and hormonal control of the vascular system of the marine mollusc, Aplysia californica

    Creator:
    Ligman, Scott H.
    Abstract:
    The vascular system of Aplysia californica is a simple visceromotor system with three main arteries innervated by a small pool of identified neurons. I used this system to study the functions of neuropeptide transmitters and their actions on neural and muscle tissues. A central finding of this study is that...
