Contemporary regional forest dynamics in the Pacific Northwest

Creator:: Reilly, Matthew J. (Matthew Justin), 1975-
Abstract:: Recent climatic warming trends and increases in the frequency and extent of wildfires have prompted much concern regarding the potential for rapid change in the structure and function of forested ecosystems around the world. Episodes of mortality in wildfires and insect outbreaks associated with drought have affected large areas and...

Analysis of the regional carbon balance of Pacific Northwest forests under changing climate, disturbance, and management for bioenergy

Creator:: Hudiburg, Tara W.
Abstract:: Atmospheric carbon dioxide levels have been steadily increasing from anthropogenic energy production, development and use. Carbon cycling in the terrestrial biosphere, particularly forest ecosystems, has an important role in regulating atmospheric concentrations of carbon dioxide. US West coast forest management policies are being developed to implement forest bioenergy production while...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

Case studies of red alder and Sitka alder in Douglas-fir plantations : nitrogen fixation and ecosystem production

Creator:: Binkley, Dan
Abstract:: Seven case studies of 11 ecosystems were used to examine the effects of nitrogen-fixing alders in Douglas-fir plantations. The first case study quantified nitrogen (N) fixation and aboveground net primary production in a young Sitka alder [Alnus sinuata (Regel) Rydb.] ecosystem. At 5 yr of age, the N fixation (C₂2H₂...

The Impact of Disturbance on Carbon Stores and Dynamics in Forests of Coastal Alaska

Creator:: Yatskov, Mikhail A.
Abstract:: Changes in climate caused by increased concentrations of carbon dioxide (CO₂) in the Earth’s atmosphere have led land and ocean surface temperatures to increase by 0.85°C and sea level to increase by 19 cm relative to preindustrial times. Global climate change will lead to further alterations in mean temperature and...

Mapping disturbance interactions from earth and space : insect effects on tree mortality, fuels, and wildfires across forests of the Pacific Northwest

Creator:: Meigs, Garrett W.
Abstract:: Given the vital role of forest ecosystems in landscape pattern and process, it is important to quantify the effects, feedbacks, and uncertainties associated with forest disturbance dynamics. In western North America, insects and wildfires are both native disturbances that have influenced forests for millennia, and both are projected to increase...

Evaluating the effectiveness of commonly used herbaceous weed control regimes in a Pacific Northwest conifer plantation

Creator:: Dinger, Eric
Abstract:: Early in the establishment of Pacific Northwest conifer plantations, herbaceous weeds often decrease seedling growth through competition for soil moisture during the dry summer months. Critical period studies have reported that reductions in competitive weed cover are necessary during the initial years of establishment to avoid reductions in seedling growth....

On the estimation and application of spatial and temporal autocorrelation in headwater streams

Creator:: Som, Nicholas A.
Abstract:: This collection of three manuscripts serves to improve methods for collecting, interpreting, and utilizing autocorrelated data from headwater stream networks. Each stream network is comprised of linear segments. These segments lie within a unique branching structure that connects the segments via flowing water, and the connectivity provided by water varies...

Potential carbon storage at the landscape scale in the Pacific Northwest, U.S.A.

Creator:: Smithwick, Erica Ann Hoffa
Abstract:: Estimates of potential carbon (C) storage can be used to constrain predictions of future carbon sequestration and to understand the degree to which disturbances, both natural aid anthropogenic, affect C storage. An upper bound on C storage in the Pacific Northwest (PNW) of the United States was estimated using field...

Ecosystem effects of vegetation removal in coastal Oregon Douglas-fir experimental plantations : impacts on ecosystem production, tree growth, nutrients, and soils

Creator:: Yildiz, Oktay
Abstract:: Effects of partial understory removal on belowground and aboveground ecosystem properties were investigated in 5 and 15 yr old Douglas-fir (Pseudotsuga menziesll (Mirb.) Franco) experimental plantations in western Oregon. Seedling survival was not affected by understory removal at age 5 yr. But through age 15 yr, understory removal increased seedling...
