Indigenous language preservation programs and language policy in education : a web-based intertextual analysis

Creator:: Muniz, Gloria J. Bock
Abstract:: There are more than 6,900 known living languages in the world, half of which could be extinct within one hundred years. Approximately 150 indigenous American languages are still spoken in the United States; however, it is estimated that by the year 2050 only twenty of them will remain. Language preservation...

The use of burned forest by breeding birds following the Biscuit Fire in southwest Oregon

Creator:: Donaghy Cannon, Michelle M.
Abstract:: Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...

Northern goshawk breeding habitat selection within high-elevation forests of southwestern Colorado

Creator:: Ferland, Cheron L.
Abstract:: The northern goshawk (Accipiter gentilis) is a species of concern in the western United States due to its association with mature structural stage forests. I employed a use-versus-availability study design to quantify the vegetative, physiographic, and landscape variables associated with goshawk breeding habitat selection in the San Juan Mountains of...

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...

Riparian bird communities in Portland, Oregon : habitat, urbanization, and spatial scale patterns

Creator:: Hennings, Lori A.
Abstract:: Urban ecosystems are characterized by human disturbance and changes in the amount, types, and spatial arrangement of wildlife habitat. The relative importance of habitat and human associated variables to urban birds is unknown. In 1999, I surveyed spring bird and plant communities along 54 perennial streams in the Portland, Oregon...

Using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon, A 'bird's eye view' : using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon

Creator:: Halstead, Katherine E.
Abstract:: The combined effects of habitat loss, degradation, and fragmentation pose a serious threat to Earth's biodiversity, imperiling even relatively common species. 'Habitat' is necessarily a species-specific concept, and investigations of bird diversity relationships and subsequent efforts to prioritize conservation areas, are challenged by the difficulty of estimating complex habitat gradients...

Life history and environmental influences on avian incubation and parental care in songbirds

Creator:: Austin-Bythell, Suzanne H.
Abstract:: Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions. Incubation, in particular, is of interest because adults must provide an environment suitable for embryonic development through nest-building and contact-incubation. We evaluated how adult incubation constancy and nest visitation...

Twenty-year changes in riparian bird communities of east-central Oregon

Creator:: Ellis, Michael S.
Abstract:: Over the last 50 years, riparian zones in the semi-arid West have gained recognition as disproportionately important habitats for both breeding bird communities and agricultural operations. Despite growing interest in exploring avian-habitat relationships in these systems to better inform land management, few studies have attempted to describe temporal changes in...

Multi-scale relationships between aspen and birds in the northern Yellowstone ecosystem

Creator:: Hollenbeck, Jeff P., 1967-
Abstract:: I conducted a multi-scale evaluation of aspen – bird relationships in the northern ungulate winter range of the northern Yellowstone ecosystem during June 2001-03. Questions addressed were: (1) Does bird diversity increase with conifer presence in aspen stands? (2) Given known habitat selection cues, are migrating birds passively intercepted by...

A characterization of seasonal pools in Central Oregon's high desert

Creator:: Dlugolecki, Laura
Abstract:: Seasonal wetlands in arid and semi-arid lands provide an important source of surface water in otherwise dry lands. Central Oregon's high desert, located in the Northern Great Basin (NGB) is dotted with hundreds of seasonal pools, locally called playas. The playas hold water or snow during parts of winter and...
