  • Larval dispersal in marine fishes: novel methods reveal patterns of self-recruitment and population connectivity

    Creator:
    Christie, Mark R.
    Abstract:
    Many marine fish populations are severely declining due to over-fishing, loss of both juvenile and adult habitats, and accelerating environmental degradation. Fisheries management and the implementation of marine protected areas (MPAs) and other conservation tools are currently hindered by large gaps in knowledge about larval dispersal and its subsequent effects...

  • Prokaryotes associated with marine crust

    Creator:
    Mason, Olivia Underwood
    Abstract:
    Oceanic crust covers nearly 70% of the Earth's surface, of which, the upper, sediment layer is estimated to harbor substantial microbial biomass. Marine crust; however, extends several kilometers beyond this surficial layer, and includes the basalt and gabbro layers. In particular, the basalt layer has high permeabilities which allows for...

  • Characterization of myosin, myoglobin, and phospholipids isolated from Pacific sardine (Sadinops sagax)

    Creator:
    Park, Joo Dong
    Abstract:
    Myoglobin (Mb) was extracted from Pacific sardine and added to Pacific whiting surimi to measure its effects on protein gelation. The purity of Mb extract was determined by SDS-PAGE. Mb extracted using ethanol showed higher purity than Mb extract using ammonium sulfate. The addition of 0.2% Mb significantly reduced breaking...

  • Impact of exotic Ponderosa pine (Pinus ponderosa Doug. ex Laws.) plantations on water resources in northwestern Patagonia, Argentina

    Creator:
    Licata, Julian A.
    Abstract:
    Exotic ponderosa pine (Pinus ponderosa Doug. ex Lawson) plantations are being planted within the natural distribution area of cordilleran cypress (Austrocedrus chilensis (D.Don) Pic. Ser. et Bizzarri) in Patagonia, Argentina. The productivity of these exotic plantations is much greater than that of native forests, suggesting greater water use. Before these...

  • Phenotypic variation in the sexual attractiveness pheromone of the red-sided garter snake, Thamnophis sirtalis parietalis

    Creator:
    LeMaster, Michael P.
    Abstract:
    Pheromones are chemical cues produced by organisms that affect the behavior and/or physiology of conspecifics. The orchestration of reproductive behaviors in many animals depends on the expression of sex pheromones. In insects, intraspecific variation in sex pheromone expression is commonly observed and often influences social interactions between individuals. To what...

  • Aquatic insect adaptations to different flow regimes

    Creator:
    Yamamuro, Asako Melody
    Abstract:
    My thesis explored the effects of environmental variability on population dynamics and community composition of aquatic insects. Environmental variability in the form of flow regime in streams can limit the distribution and life-history traits of aquatic insects. I used tributaries to the McKenzie River in Oregon with dramatically different flow...

  • The optimization of thin film p-CuO/n-ZnO heterostructures for use in selective gas detection

    Creator:
    Dandeneau, Christopher S.
    Abstract:
    Since bulk p-CuO/n-ZnO heterocontacts were first proposed for gas detection, rapid development has taken place in improving the overall functionality of these structures. While bulk heterocontacts have been shown to exhibit desirable sensitivity and selectivity characteristics, these devices suffer from innate diffusion and ZnO/CuO connectivity drawbacks that limit their effective...

  • On the evolution of correlated color traits in garter snakes

    Creator:
    Westphal, Michael F.
    Abstract:
    How complex traits evolve continues to be a major focus of evolutionary investigation. A current topic of debate is the hypothesis that the phenotypic integration of complex traits gives rise to evolutionary constraints. I studied two color traits in the common garter snake, Thamnophis sirtalis, that show a high level...
