Family aided community treatment as an intervention for the treatment of early psychosis : a proof of concept study

Creator:: Melton, Ryan P.
Abstract:: Major psychotic disorders are one of the leading causes of disability worldwide, having severe impacts on the people who suffer from the conditions, their families and society. There is evidence that if these conditions are identified and treated early, the prognosis is improved. The purpose of this dissertation study is...

The Response of Ventenata dubia to Prescribed Fire and Ungulate Grazing on the Pacific Northwest Bunchgrass Prairie

Creator:: Ridder, Luke W.
Abstract:: Ventenata dubia L. (ventenata) is an introduced, winter annual grass that has recently been raising concerns across the Pacific Northwest Bunchgrass Prairie and the Palouse Prairie. It is well established now in pasturelands, croplands, and a variety of ecosystems including grasslands, sagebrush steppe, ponderosa pine forests and woodlands. Ventenata is...

The Effects of Nitrate and a Pathogenic Fungus, Batrachochytrium dendrobatidis, on Amphibians

Creator:: Negru, Delia
Abstract:: The current rate of global biodiversity loss and extinctions is unparalleled and a major concern. Freshwater organisms are facing particularly rapid rates of biodiversity loss. Amphibians, which require an aquatic environment for part of their life cycle, are one of the most vulnerable vertebrate groups. Amphibians are experiencing population declines,...

Disentangling the Biotic and Abiotic Drivers of the Amphibian Disease Chytridiomycosis

Creator:: Bradley, Paul W.
Abstract:: The ongoing worldwide loss of biodiversity has been described as a "biodiversity crisis," "the Anthropocene defaunation," and alternatively "an extinction spasm." More recently, many scientists have come to the conclusion that we are witnesses to Earth's sixth major mass extinction event, which has the potential to fundamentally alter basic ecological...

A Historical and Archaeological Evaluation of Fort Yamhill's Hospital Site (35PO75)

Creator:: Wesseler, Kimberly A.
Abstract:: During the summer of 2016, Oregon State University conducted preliminary excavations of the hospital at Fort Yamhill, Oregon (35PO75). Fort Yamhill (1856-1866), has long been a focus of OSU’s field schools, offering glimpses into garrison life through the eyes of the officers and the enlisted men. However, up until recently,...

Economic Benefit from Allowing Wildfires to Burn in Federal East-Side Cascade Forests

Creator:: Gagnon, Aaron R.
Abstract:: In this thesis I examine the question: can allowing a wildfire to burn this year result in a net positive economic gain? To answer this question I created 2,500 multiple sets of paired scenarios (called a fire of interest) which consist of ignitions, vegetation growth, and timber harvest over the...

Emerging infectious disease in lentic environments : the ecology and biogeography of the amphibian chytrid fungus Batrachochytrium dendrobatidis, with perspectives on water quality, limnology, and chemical contaminants

Creator:: Chestnut, Tara
Abstract:: Biodiversity losses in terrestrial, freshwater, and marine systems are accelerating at a global scale and the most threatened vertebrate taxa are those associated with freshwater habitats. The causes of biodiversity losses are often complex and include synergistic effects of natural and human-induced stressors, such as habitat loss and fragmentation, urbanization,...

Characterization of Vibrio parahaemolyticus isolated from Oregon and Washington coastal water and development of improved methods for Vibrio parahaemolyticus detection

Creator:: Duan, Jingyun
Abstract:: Distribution of Vibrio parahaemolyticus in Oregon and Washington oystergrowing areas was studied between November 2002 and October 2003. V. parahaemolyticus was detected in 14.3% of oyster, 23.0% of seawater, and 44.4% of sediment samples with very low levels (≤7.4 MPN/g) of pathogenic strains being detected in oysters. Occurrence of V....

Development of baseline data on Oregon's high desert vernal pools

Creator:: Wyland, Sara Alice
Abstract:: Vernal pools are ephemeral surface water wetlands with unique hydrology, ecology and species composition. Rare and endemic species rely on vernal pool habitat due to specialization traits the species possess because they are adapted to the extreme conditions. Many vernal pool basins have been topographically and hydrologically altered and are...

Woody riparian species patterns along northeast Oregon mountainous streams and the relationship to riparian capability

Creator:: Yancey, Jennifer M.
Abstract:: Woody riparian vegetation is an essential component of riparian ecosystems, responsible in part for the maintenance of functional ecological processes. The plant community composition and distribution provide an indication of the underlying mosaic of environmental attributes and processes. Restoration and management of riparian communities have been hindered by the lack...
