Economic costs of long-term sea level rise on the Oregon coast : A case study of the Siletz Littoral Cell

Creator:: Fleck, William K.
Abstract:: Given the broad scientific consensus that global climate is changing, it is no longer a question if sea level will rise, but rather by how much will it rise. The regional estimates for the Eastern Pacific suggest that the Northwest coastlines will experience a greater eustatic sea level rise than...

Seasonal abundance and behavior of Steller sea lions in Oregon

Creator:: Katalinich, Jennifer D.
Abstract:: Behavioral studies of populations provide clues as to what influences their movements and life history strategies. This is an area of study that has been underutilized in research surrounding the declining western stock of Steller sea lions, Eumet opias jubatus, particularly with regards to haulout behaviors. During the time of...

Modeling the energetics of Steller sea lions (Eumetopias jubatus) along the Oregon Coast

Creator:: Malavear, Maria Yolanda Garcia
Abstract:: A dynamic bioenergetic model for Steller sea lions (Eumetopias jubatus) was built using the STELLA simulation modeling system. The model is intended as an aid for the exploration of ecological questions regarding growth and survival of immature Steller sea lions (ages 1-3) living along the Oregon coast under different nutritional...

Conserved properties in the metagenome of a large bacterioplankton population

Creator:: Wilhelm, Larry John
Abstract:: Candidatus Pelagibacter ubique is the first cultured representative of the SAR11 clade, a clade that is found throughout the oceans and accounts for approximately 25% of all bacterial cells [1]. It has a streamlined genome that is the smallest of any known free-living organism. In this study the complete genome...

The effects of water and shade treatments on photosynthesis and root-rhizosphere respiration in young ponderosa pine

Creator:: Johnson, Theresa J.
Abstract:: Water treatments were applied to young ponderosa pine trees in the Eastern Cascades, Oregon during the 2003 growing season, and shade treatments were applied during the 2003 and 2004 growing seasons to understand how photosynthesis and soil respiration, particularly the root/rhizosphere fraction (R[subscript rrh]), would respond to increased moisture availability...

Sea urchin-kelp forest communities in marine reserves and areas of exploitation : community interactions, populations, and metapopulation analyses

Creator:: Moctezuma, Gabriela Montaño
Abstract:: Marine ecosystems can be exposed to natural and anthropogenic disturbances that can lead to ecological failures. Marine reserves have been lately suggested to protect marine populations and communities that have been affected by habitat destruction and harvest. This research evaluates the potential role of two marine reserves established in Oregon...

Comparison of the water relations characteristics of woody plants in western Oregon

Creator:: Davis, Kent J.
Abstract:: I studied the water relations traits, twig conductivity, C'3 isotopic composition, and wood density of three conifer and five angiosperm species in western Oregon. This study took place from spring 2002 to fall 2003 on four sites. Species were selected to represent the diversity of drought tolerance of woody plants...

Steller sea lions (Eumetopias jubatus) of Oregon and Northern California: seasonal haulout abundance patterns, movements of marked juveniles, and effects of hot-iron branding on apparent survival of pups at Rogue Reef

Creator:: Scordino, Jonathan
Abstract:: The Steller Sea Lion Research Initiative was passed in 2001 to provide funding to help scientists determine causes and solutions for the population crash of Steller sea lions (Eumetopias jubatus). In response to need to understand population dynamics of Steller sea lions, NOAA Fisheries has spearheaded a large-scale, range-wide research...

Conservation education in free-choice learning environments : the effects of animals and interpretation

Creator:: Hodak, Eleanor
Abstract:: With 150 million people visiting accredited zoos and aquariums annually, these institutions have the unique opportunity to present conservation-oriented messages to a large and receptive audience. The purpose of this study was to explore the role of interpretation and/or the viewing of live animals in the communication of these messages....

Seasonal floodplain wetlands as fish habitat in Oregon and Washington

Creator:: Baker, Cynthia F.
Abstract:: To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...

Economic impact study for Detroit Lake and the Upper North Santiam Canyon

Creator:: Sorte, Bruce, Buerger, Chris, and Oregon State University. Extension Service
Abstract:: "This report profiles the demographic and economic trends within the Upper North Santiam Canyon (UNSC). We describe the economic structure and determine the export base of the UNSC. We estimate the economic impacts of a water level in the Detroit Lake that is too low for the moorages to operate...

The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

Creator:: Miller, Scott W.
Abstract:: I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...

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...
