  • Limitations to Seedling Regeneration on Tropical Forest Restoration Plantations in Northern Thailand

    Creator:
    Sangsupan, Hathai A.
    Abstract:
    This dissertation investigated potential ecological limitations to seedling regeneration in young, seasonally dry, evergreen forest restoration plantations in northern Thailand. We explored whether recruitment of colonizing tree species in the restoration plantations can be attributed to seed dispersal mode (i.e. abiotic or animal dispersal) and seed size. We did this...

  • Internalized Racism and Depression: The Moderating Role of Racial Idenitity

    Creator:
    Mitchell, Jazlyn M.
    Abstract:
    The current study aimed to further explore the relationship between internalized racism and depression, using racial identity (centrality) as a moderator. The current study was guided by two hypotheses. First, it was hypothesized that internalized racism would predict depression. Second, it was hypothesized that racial identity (centrality) would moderate the...

  • Modern Piracy: Regional Cooperative Security: Southeast Asia and the Middle East

    Creator:
    Christensen, Adam K.
    Abstract:
    Over the past ten years, reports of piracy and other forms of maritime violence have been dramatically on the rise. As these reports increase, so too does international attention toward how to solve this. This thesis examines the development of cooperative maritime security efforts in both Southeast Asia and the...

  • Microbial and biochemical dynamics of ectomycorrhizal mat and non-mat forest soils

    Creator:
    Kluber, Laurel A.
    Abstract:
    Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...

  • The evolutionary stability of partial migration

    Creator:
    Ohms, Haley A.
    Abstract:
    Natural selection, in its most basic form, is described as a process in which traitsincrease or decrease in frequency depending on their fitness, and only the trait withthe highest fitness will remain in the population. Yet, populations rarely have asingle `optimal' trait. The way natural selection maintains this observed variationwithin...

  • Using OPEC as a Villain in Narratives

    Creator:
    Merritt, Joshua A.
    Abstract:
    The Organization of Petroleum Exporting Countries (OPEC), a group formed in 1960 and often blamed for the oil shock of 1973, is treated as a cartel that aims to limit oil production and hold oil price at a level above market equilibrium. Recent research has offered a counter theory that...

  • Translational Studies of the High Molecular Weight Polycyclic Aromatic Hydrocarbon, Dibenzo[ def,p] Chrysene; Carcinogenesis and Metabolism

    Creator:
    Madeen, Erin
    Abstract:
    The objective of this work is to add to the body of translational data between high dose animal model research and the environmentally relevant human metabolism of the persistent pollutant dibenzo[def,p]chrysene (DBC). We furthered the knowledge of gene/exposure interactions by determining the carcinogenesis risk based on Cyp1b1 genotype following in...

  • Response of Soil Microbial Activity and Community Composition to Timber Harvest in an Oregon Douglas-Fir Forest

    Creator:
    Martin, Kelsey M.
    Abstract:
    Forests and forest soils are some of the largest biologically active carbon reservoirs in the world. Therefore, understanding how disturbances, such as forest harvest, influence biogeochemical cycling is particularly important for managing forests sustainably. Timber harvest can have large impacts on forest soils, which may affect the long-term productivity and...

  • The role of CYP2E1 and CYP4A in the development of non-alcoholic steatohepatitis

    Creator:
    Hawkins, Jenna M.
    Abstract:
    Non-alcoholic Steatohepatitis (NASH) is an emerging form of liver disease associated with obesity, type II diabetes and dyslipidemia. As the prevalence of these metabolic conditions increases, so too has the occurrence of NASH in all sectors of the population. The pathology of this disease is similar to its alcoholic form,...

  • Response of soil microbial communities and nitrogen cycling processes to changes in vegetation inputs

    Creator:
    Brewer, Elizabeth Ann
    Abstract:
    Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...
