Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

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...

Functional decreases in hydraulic and mechanical properties of field-grown transgenic poplar trees caused by modification of the lignin synthesis pathway through downregulation of the 4-coumarate:coenzyme A ligase gene

Creator:: Voelker, Steven L.
Abstract:: Society uses massive quantities of wood fiber in production of paper, and demand for fiber is projected to increase further as production of biofuels from fermentation of plant cellulosic materials increases. Because these end uses generally require the costly step of removing of lignin, wood with reduced or more easily...

Forest Response to Water Availability and Disturbance in the Western United States

Creator:: Berner, Logan T.
Abstract:: Earth’s atmosphere is unequivocally warming due to CO₂ and other greenhouse gas (GHG) emissions from human activities and this is having widespread impacts on forest ecosystems that provide important services to human societies. Forest ecosystems help regulate atmospheric CO2 concentrations by sequestering carbon in tree biomass and soils, which is...

Evaluating the impacts of a classroom-based citizen science project on nature connectedness, science identity, and knowledge of curricular material

Creator:: Williams, Katherine A.
Abstract:: Environmental education programs seek to foster an appreciation for the natural world while introducing students to scientific thinking. Citizen science engages non-scientists in the systematic collection and analysis of data. The Betts Forest Landscape Ecology Lab combines both goals by inviting teachers in Corvallis, Oregon, and surrounding areas to participate...

Created Snag Dynamics and Influence on Cavity-nesting Bird Communities over 25 years in Western Oregon

Creator:: Barry, Amy Marie
Abstract:: Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function...

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...

Physiological Responses of Loblolly Pine and Douglas-fir Seedlings from Various Provenances to Timing and Frequency of Drought Stress

Creator:: Mosel, Jamie E.
Abstract:: Drought is expected to increase in many parts of the world and has been shown to affect tree physiology and growth, with seedlings being particularly vulnerable. Seedling drought responses are often species dependent, and even within species different populations may demonstrate a spectrum of responses to drought, from susceptibility to...

Wild Waters : Perspectives on Oregon’s Marine Reserves as Marine Wilderness Areas

Creator:: Johnston, Jennifer R.
Abstract:: Designation of areas as marine wilderness has been proposed as a strategy for managing the increasing threats facing the world’s oceans. Although social factors influence marine protected area success, the human dimensions of marine wilderness remain minimally explored. This thesis examines views of marine wilderness expressed by a representative sample...

Understanding Citizen Advisory Boards : A National Census of Tree Boards

Creator:: Greenleaf, Sarah (Sarah Maleno)
Abstract:: Effective management of urban forests is vital to society due to the numerous ecological, economic, and social benefits they provide. In many cities, management efforts are commonly supported by citizen advisory groups, which are often generically referred to as “tree boards” within the urban forestry context. Very little is known...
