Ecosystem Functions of Pacific Northwest Estuaries: The Role of Ocean and Watershed Drivers in Eelgrass and Coho Salmon Dynamics

Creator:: Magel, Caitlin L.
Abstract:: Interest is expanding for the potential role of estuaries, particularly seagrass and salt marsh habitats, to sequester carbon, mitigate ocean acidification, and support abundant fisheries. The important functions of estuaries are part of a broader set of ecosystem services, or benefits to humans, which are regulated by ocean and watershed...

Exploration of statistical methods for synthesizing the effects of variable-retention harvesting on multiple taxa

Creator:: Lam, Tzeng Yih
Abstract:: Variable-retention harvesting was proposed to reduce loss of biodiversity and ecosystem processes associated with late-seral Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest. The Demonstration of Ecosystem Management Options experiment was established to test this hypothesis. Analysis presents various challenges to drawing statistical inferences about treatment effects. This dissertation explored...

Coastal ocean variability inferred from high resolution models : two case studies

Creator:: Mauch, Matthew L.
Abstract:: In this thesis, high resolution ocean models are used to evaluate and forecast coastal ocean variability in two different applications. In the first study, the 2-km resolution ocean circulation model for the Eastern Bering Sea is utilized to understand whether slope-interior exchange along the path of the Aleutian North Slope...

College student novice spreadsheet reasoning and errors

Creator:: Hoag, James A.
Abstract:: The spreadsheet has become a common technology tool and is now a predominant form of end-user programming. Some of the same features that make spreadsheets excellent tools for ad-hoc development can introduce errors into the final product. Although a variety of research has been performed investigating methods to detect errors...

Effect of whey concentrate crystallization parameters on lactose crystal forms

Creator:: Nonnemacher, Melissa L.
Abstract:: Effects of whey concentrate crystallization parameters of temperature, pH, and length of time of crystallization on lactose crystal forms and amount of lactose crystallized were investigated. Effect of crystallization parameters on freeze-dried powder quality was also investigated. Lactose crystal forms were observed in x-ray crystal diffraction patterns of freeze-dried whey...

Behavioral constraints on harlequin duck population recovery from the Exxon Valdez oil spill in Prince William Sound, Alaska

Creator:: Rizzolo, Daniel J.
Abstract:: I investigated the relationship between harlequin duck (Histrionicus histrionicus) behavior and lack of recovery from the Exxon Valdez oil spill in Prince William Sound, Alaska. First, I evaluated the hypothesis that harlequin ducks in winter have little flexibility to increase foraging time in response to disturbance because they are constrained...

The influence of biophysical feedbacks and species interactions on grass invasions and coastal dune morphology in the Pacific Northwest, USA

Creator:: Zarnetske, Phoebe Lehmann
Abstract:: Biological invasions provide a unique opportunity to study the mechanisms that regulate community composition and ecosystem function. Invasive species that are also ecosystem engineers can substantially alter physical features in an environment, and this can lead to cascading effects on the biological community. Aquatic-terrestrial interface ecosystems are excellent systems to...

Coastal Dune Ecology, Geomorphology, and Ecosystem Services : How Invasive Beachgrasses, their Interactions, and Sediment Dynamics Shape U.S. Pacific Northwest Dunes

Creator:: Biel, Reuben G.
Abstract:: Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the...

Predictability and constraints on the structure of ecological communities in the context of climate change

Creator:: Barner, Allison K.
Abstract:: Ecologists must increasingly balance the need for accurate predictions about how ecosystems will be affected by climate change, against the fact that making such predictions at the ecosystem-level may be infeasible. Although information about responses of individual species to a changing environment is increasing, scaling such information to the community...

Kenward-Roger approximate F test for fixed effects in mixed linear models

Creator:: Alnosaier, Waseem S.
Abstract:: For data following a balanced mixed Anova model, the standard Anova method typically leads to exact F tests of the usual hypotheses about fixed effects. However, for most unbalanced designs with most hypotheses, the Anova method does not produce exact tests, and approximate methods are needed. One approach to approximate...
