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...

Tree Species Selection Across Municipalities in the Pacific Northwest

Creator:: Petter, Joshua S.
Abstract:: There are many benefits provided by trees in urban areas. While there are many recommendations on maximizing the returns from urban trees, there has been little research examining how these managers are prioritizing their tree species selection. A survey instrument was constructed to survey Tree City USA designated cities across...

Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

Creator:: Barnard, Holly Rene
Abstract:: The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...

Differences in Evolutionary History and Ploidy Type Shape the Interactions of Populus tremuloides Michx. with Climate

Creator:: Greer, Burke Thomas
Abstract:: Quaking aspen (Populus tremuloides Michx) is a species with high phenotypic plasticity and a broad distribution that, in the last decade, has experienced climate stress-induced mortality called Sudden Aspen Decline (SAD). In order to help mitigate the effects of SAD in the future, we need a better understanding of aspen’s...

Above- and belowground controls on water use by trees of different wood types in an eastern US deciduous forest

Creator:: Meinzer, Frederick C., Woodruff, David R., Eissenstat, David M., Lin, Henry S., Adams, Thomas S., and McCulloh, Katherine A.
Abstract:: Stomata control tree transpiration by sensing and integrating environmental signals originating in the atmosphere and soil, and co-occurring species may differ in inherent stomatal sensitivity to these above- and belowground signals and in the types of signals to which they respond. Stomatal responsiveness to environmental signals is likely to differ...

Recovering Lost Ground : Effects of Soil Burn Intensity on Nutrients and Ectomycorrhiza Communities of Ponderosa Pine Seedlings

Creator:: Cowan, Ariel D.
Abstract:: Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in ponderosa pine (Pinus ponderosa Dougl. ex Laws) forests of central Oregon. The combustion of fuels containing large downed wood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previous studies...

Identifying factors driving sensitivity to fragmentation in forest breeding songbirds

Creator:: Valente, Jonathon J.
Abstract:: Habitat loss and fragmentation are the greatest threats to biodiversity worldwide. Fragmentation impacts landscape configuration, resulting in a larger number of patches that are smaller in size and further apart from one another. Island biogeography and metapopulation theory predict populations in these remnant patches should be smaller, have higher extinction...

Competition release and climate change effects on a moisture-demanding tree species in a dry system

Creator:: Seager, S. Trent
Abstract:: Climate change and the increase in meteorological drought have generated global concern over the persistence of ecosystems already in decline from decreased moisture. Evidence suggests dryland ecosystems have been more impacted by drought because of their tightly coupled growth-water relationships and high sensitivity to environmental shift. Removal of competing vegetation...

Social Capital, Collaboration, and Participation: How Social Factors Impact Community Wildfire Protection Plans (CWPP) with a Case Study on Ouray, Colorado

Creator:: Weickhardt, Adrianna K.
Abstract:: Populated and developed areas at the fringes of or intermixed with undeveloped landscapes are referred to as the Wildland Urban Interface (WUI). There are many unique benefits associated with living in the WUI that understandably attract people to move to them. However, there are also potential wildfire-related risks particular to...

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...
