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...

The Effect of Sill Height on Decay in Air-Seasoning Crossties

Creator:: Rogers, Leon R.
Abstract:: The sustainable use of wood for rail ties requires chemical treatment to increase service life and maintain structural integrity. Treatment can only be applied after lengthy air-seasoning to reduce moisture content in wood, but seasoning leaves ties exposed to attack by decay fungi for up to a year. One factor...

The roles of provenance and phylogeny in recruitment, community assembly, and species coexistence in invaded California grasslands

Creator:: Brandt, Angela J.
Abstract:: Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...

Human Alteration of a Neotropical Landscape Drives Long-term Changes in its Forest Bird Communities

Creator:: Curtis, Jenna R.
Abstract:: Human alteration of natural landscapes leads to biodiversity loss, often from a combination of area effects and fragmentation effects. Smaller habitat patches support fewer species than large ones and incur additional consequences from isolation. Efforts to preempt biodiversity loss from insular habitat fragments are complicated by individualistic species responses and...

Epidemic Dynamics of Sudden Oak Death in the Forests of Oregon

Creator:: Carson, Adam
Abstract:: Sudden Oak Death (SOD) is a forest disease caused by the oomycete pathogen Phytophthora ramorum, and infects trees in the Western United States and Europe. This generalist pathogen can infect over 130 species of plants, and causes rapid mortality in tree species in the Fagaceae. Sexual reproduction is thought to...

Non-native and native plant species distributions and variability along an elevation gradient in the Wallowa Mountains, Oregon

Creator:: Averett, Joshua P.
Abstract:: Invasion by non-native plants into natural areas is an important component of global change that threatens biodiversity and ecosystem structure and function. Mountains are currently among the least invaded ecosystems, however, these biodiversity hotspots are increasingly under threat of exotic plant invasion. Evaluation of plant species distribution patterns in mountain...

Patterns of distribution, abundance, and change over time in the marine bird community of Prince William Sound, Alaska, 1989-2012

Creator:: Cushing, Daniel A.
Abstract:: Over recent decades, the marine ecosystems of Prince William Sound (PWS), Alaska have experienced the concurrent effects of a major anthropogenic disturbance, the 1989 Exxon Valdez oil spill (EVOS), and a dynamic atmospheric-oceanic environment. Studies of top marine consumers can provide insights into processes of ecosystem change. Using data collected...

Chaparral history, dynamics, and response to disturbance in southwest Oregon : insights from age structure

Creator:: Duren, Olivia
Abstract:: Fuels management on Bureau of Land Management lands in SW Oregon, USA, is motivated by the needs to reduce fire hazard and restore ecosystems thought to be impacted by fire suppression. Chaparral is one of the most characteristic vegetation communities of SW Oregon's interior valleys, and extensive acreages within this...

The Influence of Wildfire and Invasive Vegetation on Mule Deer

Creator:: Schuyler, Elizabeth
Abstract:: The western United States has experienced large-scale degradation due to land use and land cover changes, invasion of annual grasses, and expansion of woody plants into grass and shrublands and the resultant altered fire regimes. These landscape-scale changes have coincided with declining mule deer (Odocoileus hemionus) populations, making habitat loss...

Tradeoffs and Synergies among Wild Ungulates, Early Successional Plant Communities and Management Intensification in Forest Plantations of the Oregon Coast Range

Creator:: Stokely, Thomas D.
Abstract:: As the global demand for natural resources increases, more land will be intensively managed for the production of commodities such as timber, with potential consequences to biodiversity, ecological functioning and ecosystem services provided to society. Although there is strong consensus that intensive land management practices can negatively affect biodiversity, less...
