Towards Narrative Understanding with Deep Neural Networks and Hidden Markov Models

Creator:: Orr, J. Walker
Abstract:: Narratives are central to communication and the human experience. For a computer system to understand a narrative, it must be able to identify the key facts or plot elements that describe what happened or how the world has changed. These element are called events;establishing a document’s events and the relationships...

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...

Beaver ecology on the west Copper River Delta, Alaska

Creator:: Cooper, Erin E.
Abstract:: Since the 1964 earthquake and geologic uplift, beavers (Castor canadensis) have expanded their historic range from the inland (outwash plain) Copper River Delta, Alaska to the once tidally influenced areas of the outer area (uplifted marsh). The uplift presents a unique opportunity to observe beaver expansion, habitat selection and influence...

Influences of high severity fire and postfire logging on avian and small mammal communities of the Siskiyou Mountains, Oregon, USA

Creator:: Fontaine, Joseph B.
Abstract:: High severity fire is a historical and integral disturbance process in coniferous forest types. Compounded disturbances such as multiple fires or post-disturbance management activities are increasingly common, but ecological responses are not well understood and may represent novel types of disturbances. I studied bird and small mammal communities in the...

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...

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...

Effects of alfalfa on uterine growth of ovariectomized prepubertal ewe lambs

Creator:: Sexson, Clinton
Abstract:: Alfalfa accumulates phytoestrogens and when ingested binds the estrogen receptor and induces morphological changes similar to endogenous estrogens. The objective of this study is to evaluate morphological changes in uteri, vulva, and teats of ovariectomized prepubertal ewe lambs. Eighteen prepubertal ewe lambs were ovariectomized in November 2000 and fed nonestrogenic...

Ecological thresholds, climate extremes, and tree species' distributions across the Pacific coastal United States

Creator:: Lintz, Heather E.
Abstract:: Species' distributions across the landscape are perhaps the least understood yet most conspicuous features of life on earth. Ecologists have long studied species' distributions; yet, many questions remain about why species occur where they do. Such questions persist largely because species' distributions are complex systems with challenging properties like non-linearity,...

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...

Complexity in host-pathogen dynamics : dispersal uncertainties, metapopulation persistence and the role of a changing climate

Creator:: Xie, Yang
Abstract:: Emerging infectious diseases impact both human and wildlife populations. Infectious agents, in particular the aquatic fungus Batrachochytrium dendrobatidis (chytrid), have an influential role in driving global amphibian population declines. The emergence of the chytrid fungus has aspects of both geographic spread as well as climate shifts altering environmental conditions and...

The importance of egg size for the diversity of salmonids

Creator:: Leblanc, Camille A.
Abstract:: Understanding the origin and nature of intra specific biodiversity enables us to better conserve and manage animal populations. Biological diversity is seen at different scales and for different traits such as behavior, morphology, physiology, and life history. Behavior is especially important since behavioral changes are believed to precede changes in...

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...

Abstract:: The environmental movement needs people from communities of color and the differing perspectives they provide. Latinas/os are one of the largest communities of color in the US, and their numbers continue to grow. However, mainstream environmental organizations have failed to engage this community in authentic ways. The lack of meaningful...

Characterizing Uncertainty and Assessing the Impact of Rapid Climate Change on the Distribution of Important Tree Species in the Pacific Northwest

Creator:: Kralicek, Karin M.
Abstract:: Climate change will impact the location of suitable habitat for tree species in the Pacific Northwest. Locations that become unsuitable will experience increased levels of tree mortality and diminished levels of tree growth. Understanding how these impacts will spatially manifest is vital for efficient management of natural resources. An invaluable...

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...
