A characterization of unmanaged riparian overstories in the central Oregon Coast Range

Creator:: Nierenberg, Tara R.
Abstract:: Riparian areas that can be used as reference sites on which to base goals of vegetation restoration have not been documented in the Oregon Coast Range. I examined the composition and distribution of unmanaged riparian overstories in the central Oregon Coast Range along nine streams which have experienced minimal disturbance...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

Stand development after 20-years of growth in Douglas-fir and red alder mixtures

Creator:: Garrelts, Brennan T.
Abstract:: This study examines the long-term role of interference on stand development of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and red alder (Alnus rubra Bong.) planted mixtures in the Central Cascades of Oregon, USA. The two species are common associates in naturally regenerated and planted conifer stands in the Pacific Northwest. Due...

Utilizing cooperative fisheries research to monitor and understand harmful algal blooms along the Oregon coast

Creator:: Gilliland, Raquel C.
Abstract:: Harmful algal blooms (HABs) are a problem for coastal communities, the fishing industry, and coastal organisms. Pseudo-nitzschia spp. is a regularly occurring diatom in Oregon’s coastal waters. At times, Pseudo-nitzschia spp. can facultatively produce domoic acid, a neurotoxin that can bioaccumulate in the food chain. While regular shore-based sampling provides...

Plant community recovery after high severity wildfire and post-fire management in the Klamath Region

Creator:: Lopez Ortiz, Maria Jose
Abstract:: Disturbance and microclimate interact to play a central role influencing the composition and structure of plant communities. In this thesis, I examined plant community composition and structure twenty years after high severity wildfires with and without post-fire management (salvage logging, fuel treatment, tree planting, and shrub release) under contrasting microclimatic...

Meander scars : reflections on healing a river

Creator:: Metzger, Abby P.
Abstract:: As Europeans settled the Willamette Valley in the 1800s, they began to simplify Oregon's largest river contained wholly within state boarders—the Willamette. The river lost miles of channels from dikes, dams, and development. Some channels vanished under concrete. Others became meander scars, or shallow, dry depression in the land where...

Decomposition and nitrogen dynamics of red alder and Douglas-fir leaf litter in Oregon Coast Range riparian forests

Creator:: Matkins, Joselin
Abstract:: I examined factors regulating decomposition rates of red alder (Alnus rubra)) and Douglas-fir (Pseudotsuga menziesii) leaf litter in Coast Range riparian areas in western Oregon. Overall, this study was designed to examine the influence that leaf litter quality characteristics and decomposition site treatment have on decomposition rates, to provide a...

Playing with pedagogy : a case study of contextual teaching and learning for the natural resources classroom

Creator:: Greene, Kim (Kimberly Kate)
Abstract:: This thesis investigates Contextual Teaching and Learning (CTL) as a method of instruction for natural resources education. The research follows the adoption of CTL in the K-12 classrooms of six teachers focusing on natural resources education at two rural schools in Western Oregon. CTL is being investigated because it connects...

Estimation and Sparse Selection of Conditional Probability Models for Vector Time Series

Creator:: Ruiz, Trevor D.
Abstract:: Diverse scientific fields collect multiple time series data to investigate the dynamical behavior of complex systems: atmospheric and climate science, geophysics, neuroscience, epidemiology, ecology, and environmental science. Identifying patterns of mutual dependence among such data generates valuable knowledge that can be applied either for inferential or forecasting purposes. Vector autoregressive...

Today, Tomorrow, and Every Day After That: How Commercial Salmon Fishermen in Bristol Bay, Alaska Define and Work Toward a Sustainable Salmon Fishery

Creator:: Kuletz, Ivan
Abstract:: Rising human global population, appetite for seafood, and the effects of climate change have pushed commercial marine fisheries around the globe onto trajectories that are chillingly unsustainable. Input from fishermen on what it means to have a “sustainable fishery” is often absent or ignored. Some commercial fisheries are lauded for...
