Forest-meadow dynamics in the central western Oregon Cascades : topographic, biotic,and environmental change effects

Creator:: Rice, Janine M.
Abstract:: Montane meadows comprise a small area of the predominantly forested landscape of the Oregon Cascade Range. Tree encroachment in the last century in these areas has threatened a loss of biodiversity and habitat. Climate change in the coming century may accelerate tree encroachment into meadows, and exacerbate biodiversity loss. Multiple...

Basins at risk : conflict and cooperation over international freshwater resources

Creator:: Yoffe, Shira
Abstract:: In the policy literature and the popular press, the issues of water and conflict are being raised together with increasing frequency. Geographic, international relations, and environmental security theories speculate on the linkages between geographic features, natural resources, spatial relationships, and war or acute conflict. Little quantitative or global-scale research exists,...

Biomass and community structure of sporocarps formed by hypogeous ectomycorrhizal fungi within selected forest habitats of the H. J. Andrews Experimental Forest, Oregon

Creator:: Luoma, Daniel L.
Abstract:: This study characterizes the production of hypogeous sporocarps (broadly referred to as truffles) by ectomycorrhizal fungi within Douglas-fir dominated forests that are considered typical of those found on the west slopes of the central Cascade mountains in Oregon. Three aspects of sporocarp production are addressed: 1) the distribution of total...

The visualization of perspective systems and iconology in Dürer’s cartographic works : an in-depth analysis using multiple methodological approaches

Creator:: Wörz, Adèle Lorraine
Abstract:: This dissertation uses a new methodological approach for an in-depth analysis of three cartographic works. Studies within the discipline of the history of cartography have followed various methodologies throughout the past century. This dissertation argues that in order to come to a more complete understanding of how maps were produced...

Stress, osmoregulation, and the hormone cortisol in yearling coho salmon, Oncorhynchus kisutch

Creator:: Redding, Joseph Michael
Abstract:: Freshwater (FW) and seawater (SW) acclimated yearling coho salmon, Oncorhynchus kisutch, were subjected to severe confinement stress in FW, SW, or a medium (1/3 SW) that was approximately isosmotic to the fish's blood. Chronic stress caused osmotic imbalances in FW and SW, but not in 1/3 SW. In SW, blood...

Physiology of interrenal function in juvenile coho salmon (Oncorhynchus kisutch) and effects of hatchery rearing practices

Creator:: Patino, Reynaldo
Abstract:: Periodic determinations of plasma hormone levels suggested that changes in interrenal activity are unrelated to changes in thyroidal or gonadal activity during development (smoltification) of juvenile coho salmon (Oncorhynchus kisutch). Moreover, in an experiment where fish were reared under various conditions of crowding and water inflow rate, it appeared that...

Systematic studies of the genus Siphateles (Ostariophysi: Cyprinidae) from western North America

Creator:: Harris, Phillip M.
Abstract:: The minnow genus Siphateles is distributed throughout the Great Basin and adjacent drainages of western North America. Three species are currently recognized in the genus: S. alvordensis, Alvord chub, S. boraxobius, Borax Lake chub, and S. bicolor, the tui chub. S. bicolor has long been recognized as a widespread species...

Residents' attitudes toward water resource protection in metropolitan Portland, Oregon

Creator:: Larson, Kelli L., 1975-
Abstract:: Three research questions are addressed in this study: (1) To what degree do residents support/oppose various aspects of water resources protection? (2) What factors explain residents' attitudes? and, (3) How do attitudes vary between participants and nonparticipants of place-based groups (watershed councils and neighborhood associations)? The population of interest is...

International river basin management : global principles and basin practice

Creator:: Giordano, Meredith A.
Abstract:: Transcending human-defined political and administrative boundaries, the world's transboundary freshwater resources pose particularly challenging management problems. Water resource users at all scales frequently find themselves in direct competition for this economic and life-sustaining resource, in turn creating tensions, and indeed conflict, over water supply, allocation and quality. At the international...

An assessment of community-based adaptive watershed management in three Umpqua Basin Watersheds

Creator:: Habron, Geoffrey Bryan
Abstract:: The dissertation introduces community-based adaptive watershed management (CAWM) as a holistic conservation framework. The CAWM framework integrates social and ecological suitability to achieve conservation outcomes. The core theoretical concepts consist of adaptive management, adoption-diffusion, symbolic interactionism, community-based conservation, spatial analysis and watershed management. The CAWM framework is applied to the...
