Particle-laden turbulent flows, wherein a large number of small size particles are dispersed in a fluid, are widely encountered in environmental and industrial applications. Understanding their underlying physics, making predictions without performing expensive experiments, and ultimately optimizing the systems carrying such flows, require accurate and robust modelling tools. The Euler-Lagrange...
Estimates of species' vital rates and an understanding of the factors affecting those parameters over time and space can provide crucial information for management and conservation. We used mark–recapture, reproductive output, and territory occupancy data collected during 1985–2013 to evaluate population processes of Northern Spotted Owls (Strix occidentalis caurina) in...
Development of wave and offshore wind-based marine renewable energy is anticipated on the Outer Continental Shelf (OCS) off Oregon and much of the Pacific Northwest in the coming decade. Multiple issues related to environmental considerations and information needs remain for these emerging industries. The Oregon Marine Renewable Energy Environmental Science...
Archaeological excavations of the Cooper's Ferry site in the Lower Salmon River Canyon, Idaho, have revealed a stratified record of cultural occupation, spanning the late Pleistocene and early Holocene periods. The purpose of this study was to contribute to the understanding of cultural adaptive strategies represented in the archaeological record...
The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...

Understanding the impact of mitochondrial dysfunction on genome evolution has the potential not only to provide new insights on the basic evolutionary processes influencing mitochondrial and nuclear genomes, but may also reveal novel avenues for evolutionary adaptive recovery from harmful mutations. Aberrant mitochondrial activity is fundamental to the pathology of...
Proceedings of Visible Possibilities: The Economics of Sustainable Fisheries, Aquaculture and Seafood Trade, the 16th Biennial Conference of the International Institute of Fisheries Economics & Trade, held July 16-20, 2012 in Dar es Salaam, Tanzania.
This dissertation develops a framework for Curandera feminism, informed by familial healing practices, women of color feminisms, and institutional critique. My research centers my family’s generational Curandera practices. As I honor the call to be critical of the master’s tools, I seek possibilities for institutional change through Curandera feminism. Institutions...
The myxozoan Ceratonova shasta is an intestinal parasite of salmon and trout that causes ceratomyxosis, a disease characterized by severe inflammation of the intestine that can lead to hemorrhaging, necrosis, and death of the fish host. The parasite is endemic to the Pacific Northwest of the United States and Canada,...
In the study of any developmental process, whether in plants, animals, or other models, it is prudent to consider the developmental position of the subjects being measured. This is generally not taken into consideration in grapevine studies despite a growing body of literature documenting that fruits within clusters develop and...
This report delineates reasonable objectives, based upon the best scientific and commercial data available at the time of its release, for the conservation and survival of greater sage-grouse. Individual team members contributed by providing technical information and data, participating in critical discussions, providing critical reviews and edits, or authoring sections...
The multifaceted role of the environment in regulating the structure and dynamics of biological communities has long fascinated ecologists and motivated much debate and research. Now, in a time of accelerated global changes due to human impacts, the need to understand how the environment shapes communities has gained new urgency....
Mutualistic associations between corals and symbiotic microalgae of the genus Symbiodium power tropical reef ecosystems, hotspots of marine biodiversity that buffer coastlines, support tourism- and fisheries-based economies, and offer untapped potential for discovery of novel pharmaceutical compounds. However, reef ecosystems are declining at an alarming rate, in large part due...
Active tectonics of a deformation front constrains the kinematic evolution and structural interaction between the fold-thrust belt and the most-recently accreted foreland basin. At the Himalayan deformation front, the thrust front is blind, characterized by a broad fold (the Suruin-Mastgarh anticline (SMA)), and displays no emergent faults cutting the southern...
This study evaluates the Earth Resources Technology Satellite-
One (ERTS-1) multispectral scanner (MSS) as a means of predicting
lacustrine trophic state and the magnitude of selected trophic state
indicators.
Numerical classificatory methods are employed to ascertain the
trophic character of 100 lakes in Minnesota, Wisconsin, Michigan,
and New York using...
The archaeological resources contained in Corvallis Riverfront
Commemorative Park (RCP) have a great potential to add to the historical
record of the warehouse district of the original town of Marysville (Corvallis).
The City of Corvallis' proposed Combined Sewer Overflow (CSO) project and
proposed changes to Riverfront Commemorative Park threaten to...
In the United States during the last 30 years there has been a shift from extractive natural resource-based economies of the Old West to a New West defined by environmental protection. Over the past century, a growing national support for environmental protection has influenced a lengthening list of national and...
