Biodiversity Responses in Early Seral Forests of the Klamath-Siskiyou: Comparisons with Birds, Bees, and Ground Beetles among Post-fire, Salvage Logging, and Intensive Forest Management Environments

Creator:: Frank, Graham S.
Abstract:: Early seral forests regenerating from stand-replacing disturbances provide unique habitat for many species in productive, temperate forest landscapes and contribute to supporting biodiversity. Population declines in some species associated with early seral forests have prompted concerns about the conservation of these habitats, particularly the characteristic structural and compositional complexity associated...

An examination of climate and land-use change as drivers of population dynamics in breeding birds

Creator:: Kim, Hankyu
Abstract:: Anthropogenic land-cover change and climate change are the major drivers of the steep loss of avian biodiversity in past decades. Loss of avian biodiversity is predicted to result in the reduction of ecosystem services and ecological functions. Identifying avian population changes and the drivers of these trajectories is essential for...

Stress Physiology in Free-ranging Female African Buffalo (Syncerus caffer) : Environmental Drivers, and Immunological and Infection Consequences

Creator:: Spaan, Johannie M.
Abstract:: Fecal glucocorticoid metabolites (FGMs) are commonly used as indicators of an animal’s stress response in behavioral and eco-physiological studies. Stress in wild animals represents an immediate measure of the physiological response to changes in the environment, and, potentially, a prospective assessment of the animal’s health and well-being. In wild mammals,...

Entrepreneurship, policy, and resource use : the production of and competition for salmon

Creator:: Clark, Jerry E., 1949-
Abstract:: Fisheries economics is a recognized body of research which is characterized by the joint study of economics, the biological characteristics of fishery resources, and the policies (regulations) used in the management of fisheries. This thesis is composed of three papers, each of which is primarily associated with one of the...

An economic analysis of farms producing grass seed in the Willamette Valley, with special attention to the cultural practice of field burning

Creator:: Fisher, Douglas Earl
Abstract:: Grass seed producers in Oregon's Willamette Valley have employed the cultural practice of post-harvest open field burning since the mid-1940's for purposes of field sanitation and crop residue disposal This practice creates environmental quality problems of air pollution during the late summer Recent public concern over the valley's environmental quality...

Surface Water and Groundwater Interactions in the Walla Walla River, Northeast Oregon, USA : A Multi-Method Field-Based Approach

Creator:: Gryczkowski, Landon
Abstract:: Surface water and groundwater interactions are a key component in the functioning of stream ecosystems. Exchange of water between the stream and the hyporheic zone creates habitat for aquatic organisms and serves as a control for stream biogeochemical, thermal, and flow processes. This study takes a multi-method field-based approach to...

Natural history and ecology of larval Lost River suckers and larval shortnose suckers in the Williamson River-Upper Klamath Lake System

Creator:: Cooperman, Michael S.
Abstract:: We monitored larval Lost River and shortnose suckers from natal beds in the Williamson and Sprague rivers to nursery grounds in Upper Klamath Lake. Downstream movements occurred at night, in the middle of the channel, and on the falling limb of the hydrograph. Ages, sizes, and developmental stages of larvae...

Transboundary river floods : vulnerability of continents, international river basins and countries

Creator:: Bakker, Marloes H. N.
Abstract:: Floods are the most frequent and damaging of all types of natural disasters and annually affect the lives of millions all over the globe. However, researchers seem to have overlooked the fact that floods do not recognize national boundaries. Therefore, the phenomena of shared, or transboundary floods occurring in international...

A numerical model for predicting energy dispersion in thermal plumes issuing from large, vertical outfalls in shallow coastal water

Creator:: Trent, Donald S.
Abstract:: A theoretical study of the heat and momentum transfer resulting from a flow of power plant condenser effluent discharged vertically to shallow, quiescent coastal receiving water is presented. The complete partial differential equations governing steady, incompressible, turbulent flow driven by both initial momentum and buoyancy are solved using finite-difference techniques...
