  • Patterns, causes, and consequences of clustering of individual territories of the threespot damselfish, Stegastes planifrons

    Creator:
    Meadows, Dwayne W.
    Abstract:
    The threespot damselfish, Stegastes planifrons, maintains individual territories that are clustered on coral patch reefs. My objective was to understand the effects of territory clustering on behavior and fitness. Fish with territories in the center of a cluster had (relative to edge fish): higher mating success (number of eggs), higher...

  • Natural history and evolution of a color polymorphism in Rana pipiens, the northern leopard frog

    Creator:
    Hoffman, Eric A.
    Abstract:
    A primary goal of population genetics is to identify the role of microevolutionary forces in producing observed patterns of molecular and phenotypic variation. I conducted four studies in the northern leopard frog, Rana pipiens, to determine just how mutation, migration, genetic drift, and selection influenced, genetic structure of mitochondrial DNA...

  • 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...

  • Quasi-stationary atmospheric responses to large-scale forcing

    Creator:
    Kang, In-sik
    Abstract:
    A time-dependent, spectral, barotropic model and a similar two-layer primitive equation model are developed to investigate the planetary-scale wave responses to various types of large-scale forcing: vorticity and heat sources, and sea surface temperature (SST) anomalies. Both models are linearized about the zonal mean states of January climatology. The characteristics...

  • Development of an information processing capacity estimation method for managing a project subjected to disruptions

    Creator:
    Ro, In Kyu
    Abstract:
    This dissertation is an attempt at developing a method for the analysis and estimation of the effects of disruptions due to uncertainties. Such uncertainties may result from design changes and engineering drawing delays in large-scale, complex, research and development, or construction projects. In order to provide management with a simple...

  • Ecological aspects of kin discriminating behavior with implications of functional value

    Creator:
    Hokit, D. Grant
    Abstract:
    To assess the context dependence of kin discriminating behavior, I examined kin-biased aggregation behavior in tadpoles of R. cascadae in different ecological conditions. I manipulated food distribution, predator presence, thermal heterogeneity, and relatedness in a multifactorial mesocosm experiment. All four factors interacted to influence tadpole dispersion. My results suggest that...

  • Cannibalism in larvae of the long-toed salamander, Ambystoma macrodactylum

    Creator:
    Wildy, Erica Lynn
    Abstract:
    Predator-prey interactions have historically been studied to explain patterns of organization observed in populations and communities. They have also been important in understanding the evolution of antipredator responses in prey and counterstrategies in predators. Despite the breadth of knowledge that exists for heterospecific interactions, relatively few studies have investigated the...

  • Seedling recruitment of hairy nightshade and other summer annual weeds in irrigated row crops

    Creator:
    Peachey, Ronald Edward
    Abstract:
    This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...

  • Chemical signaling and pheromone evolution in plethodontid salamanders

    Creator:
    Palmer, Catherine Anne
    Abstract:
    My dissertation focuses on the evolutionary forces that have shaped the chemical signaling system of plethodontid salamanders. Pheromones mediate two phases of plethodontid reproduction: mate attraction prior to courtship and female persuasion during courtship. Substrate-borne chemical signals are believed to play an important role in mate attraction for these animals....
