Habitat use and productivity of Rio Grande wild turkey hens in southwestern Oregon

Creator:: Keegan, Thomas W.
Abstract:: Wild turkey (Meleagris gallopavo) ecology has been examined within its native range, but knowledge of extralimital populations of Rio Grande wild turkeys (M. g. intermedia) is lacking. I investigated habitat use, characteristics of activity sites, home ranges and movements, productivity, and survival of Rio Grande turkey hens from 1989 through...

Biophysical factors driving the distribution and abundance of redband/steelhead trout (Oncorhynchus mykiss gairdneri) in the South Fork John Day River Basin, Oregon, USA

Creator:: Madriñán, Luis Francisco
Abstract:: The overall goal of this study was to identify multiple scales of habitat use and habitat electivity by redband/steelhead trout and define the limiting factors affecting the distribution patterns of this species during summer flows. The main objective in chapter 2 was to identify the most important habitat associations that...

Nitrogen dynamics across silvicultural canopy gaps in young forests of western Oregon

Creator:: Thiel, Aaron L.
Abstract:: Silvicultural canopy gaps are emerging as an alternative management tool to accelerate development of complex forest structure in young, even-aged forests of the Pacific Northwest. I investigated patterns of nitrogen (N) availability along transects through 0.1 and 0.4 ha silvicultural gaps in three 50-70 year old Douglas-fir forests of western...

Development, fire history and current and past growth, of old-growth and young-growth forest stands in the Cascade, Siskiyou and mid-coast mountains of southwestern Oregon

Creator:: Sensenig, Thomas S.
Abstract:: I evaluated fire occurrence, growth and recruitment and determined the fire history of 21 old and 20 young 8ha stands in Cascade, Siskiyou and mid-Coast mixed conifer and evergreen forests in southwestern Oregon. The rates and patterns of growth were measured and analyzed on 1,079 old-growth and 2,111 young stand...

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...

Establishment and growth of natural and planted conifers ten years after overstory thinning and vegetation control in 50-year-old Douglas-fir stands

Creator:: Nabel, Mark R.
Abstract:: Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...

Chemical modification of wood : dimensional stabilization of viscoelastic thermal compressed wood

Creator:: Gabrielli, Christopher P.
Abstract:: The tendency of wood to shrink and swell with changing moisture content remains as one of the most significant challenges to using wood in its many applications. Viscoelastic Thermal Compression (VTC) has been shown to significantly increase the density, strength and stiffness of wood. However, dimensional stability is still a...

Age-specific and lifetime reproductive success of known age Northern Spotted Owls on four study areas in Oregon and Washington

Creator:: Loschl, Peter J.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) are a long-lived forest owl and range-wide declines in their numbers have resulted in the species being listed as threatened under the endangered species act. While many studies have been focused on population trends and reproductive performance of Spotted Owls from different age-classes, none...

Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:: Litz, Marisa N. C.
Abstract:: Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...

The Oregon eugenic movement : Bethenia Angelina Owens-Adair

Creator:: Currey, Linda Lorraine
Abstract:: In 1906, applying Charles Darwin's evolutionary theories to the human race, Sir Francis Galton introduced the concept of eugenics, "the science of the improvement of the human race by better breeding." The rediscovery in 1900 of Mendel's laws of genetic inheritance and an upsurge in hereditarian thought set the stage...
