  • Life in a Rapidly Changing Environment: The Thermal Biology of the Red-sided Garter Snake (Thamnophis sirtalis parietalis)

    Creator:
    Hubert, David L.
    Abstract:
    At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...

  • Characterizing the Function of the Harderian Gland and its Interactions with the Vomeronasal Organ in the Red-sided Garter Snake, Thamnophis sirtalis parietalis

    Creator:
    Bentz, Ehren
    Abstract:
    The Harderian gland is a large cephalic gland present in most groups of terrestrial vertebrates. Although the Harderian gland has been the focus of numerous studies for more than 300 years, its physiological function has remained largely unresolved. Harderian gland secretions are diverse among different taxa, and many putative functions...

  • 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...

  • Nonlinear diffraction theory by an eigenfunction expansion of the Green's function

    Creator:
    Chen, Min-Chu
    Abstract:
    A second-order nonlinear diffraction theory is developed for a large diameter circular cylinder under the action of surface gravity waves of finite amplitude in water of-finite depth. Boundary value problems are derived by using a perturbation expansion and the solutions for the diffracted waves are given in terms of Fredholm...

  • Mass transport in laboratory water wave flumes

    Creator:
    Kim, Tae In
    Abstract:
    A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

  • Irregular points in wavemaker boundary value problem

    Creator:
    Tanaka, Yoshihiro
    Abstract:
    A global solution is presented that accurately accounts for the singular behavior at all irregular points. The linearized boundary value problem in a semi-infinite strip in the physical plane is transformed into a smooth unit disk by two successive conformal mappings. The global solution results from a Fredholm integral equation...

  • Patterns and mechanisms : postcopulatory sexual selection and sexual conflict in a novel mating system

    Creator:
    Friesen, Christopher R.
    Abstract:
    Postcopulatory sexual selection—sperm competition and cryptic female choice—has become a major area of research over the past 40 years. Within this field there are many outstanding questions at every level of analysis, from proximate to ultimate. The fitness consequences for both sexes in the period after copulation and before fertilization...

  • Chaos in a long rectangular wave channel

    Creator:
    Bowline, Cynthia M.
    Abstract:
    The Melnikov method is applied to a model of parametrically generated cross-waves in a long rectangular channel in order to determine if these cross-waves are chaotic. A great deal of preparation is involved in order to obtain a suitable form for the application of the Melnikov method. The Lagrangian for...

    Abstract:
    The Wiggins-Holmes extension of the generalized Melnikov method (GMM) is applied to weakly damped parametrically excited cross waves with surface tension in a long rectangular wave channel in order to determine if these cross waves are chaotic. The Lagrangian density function for surface waves with surface tension is simplified by...

  • Pheromonal mediation of reproductive behavior in the brown tree snake

    Creator:
    Greene, Michael John
    Abstract:
    In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...
