Economic and social impacts of restoration : a case study of the Great Basin Region

Creator:: Satyal, Vijayanand H.
Abstract:: The last five decades of research in arid land ecology cites Invasive species as a source of imbalances in biodiversity through habitat destruction and reductions of native species through ecosystem alterations in favor of non-native species. Invasive species are known to damage not only the surrounding ecosystem but also cause...

Vegetation composition and response to fire of native Willamette Valley wetland prairies

Creator:: Pendergrass, Kathy L. (Connelly)
Abstract:: Fires set by Native Americans were important in shaping and maintaining Willamette Valley prairie plant communities. With fire exclusion after Euro-American settlement in the 1840's, composition of the remaining prairies shifted toward shrub and tree dominance with a concomitant decline in endemic prairie plant populations. I hypothesize that by restoring...

Spatial and age class analysis of managed western juniper (Juniperus occidentalis) woodlands in central Oregon

Creator:: Zophy, Kelley T.
Abstract:: Juniper is a native species to Oregon and confers ecological benefits to wildlife when it is at savannah and transitional densities. Its range and extent have fluctuated with climatic change, but the current range expansion is unprecedented in its extent. The range expansion has been associated with the degradation of...

Rubus spp. seed germination and morphology

Creator:: Peacock, Derek N.
Abstract:: Rubus spp. seeds have a thick protective endocarp and testa (seedcoat) that can restrict germination even under favorable conditions. The effect of pregermination treatments were studied in Rubus chamaemorus L., R. eustephanos Focke ex Diels, R. idaeus 'Amber' L., R. leucodermis Douglas ex Torrey & A. Gray, R. multibracteatus A....

Fire effects on vegetation diversity, structure, and successional dynamics in shrub-steppe and mixed conifer environments of the Hells Canyon, Idaho

Creator:: Havlina, Douglas William
Abstract:: The effects of fire severity on post-fire succession and shrub demography were quantified in shrub-steppe grasslands and subalpine forests in the Hells Canyon of the Payette National Forest, Idaho. Following the 1988 Eagle Bar Fire, species frequency, community diversity, fire adaptations, and stand ages were quantified at 12 plots in...

Restructuring of land and community in the remote rural west : the case of Wallowa County, Oregon

Creator:: Abrams, Jesse
Abstract:: Since at least the 1970s, rural areas in the western United States, as elsewhere across the country and world, have been subject to social, economic, and political forces that have resulted in novel demographic and land tenure trends when compared to previous decades. Collectively, these processes of restructuring have created...

Nutritional value of several Opuntia species

Creator:: Ben-Thlija, Abdellaziz
Abstract:: Little is known about cactus nutrients, their proportions in different species and the variability of these proportions with season. In the scant literature available on Opuntia species, no systematic survey has been published to document and compare the nutritional qualities of different species. Also, no studies have been done to...

Fire severity and vegetation response to fire in riparian areas of the Biscuit and B&B Complex Fires, Oregon

Creator:: Halofsky, Jessica E.
Abstract:: Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...
