Simulated response of ecosystem processes to climate change in northern California and western Nevada

Creator:: McGlinchy, Maureen C.
Abstract:: In order to investigate potential climate impacts on landscape-scale ecosystem processes, I implemented a dynamic general vegetation model (DGVM) over a large domain in northern California and western Nevada on a rectangular grid of ca. 800-meter spatial resolution. I used 100 years of observed, monthly climate and nine future climate...

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...

Examining ectomycorrhizal communities of ponderosa pine and lodgepole pine in the south-central Oregon pumice zone

Creator:: Garcia, Maria Osuna
Abstract:: Background information is presented that provides historical perspectives on the field of mycology in the Pacific Northwest and its role in forest management. The series of events and decisions that have led to previous studies (or lack of studies) in the field also dictate the directions of current research. Culture,...

Understanding Public Perceptions of Post-Wildfire Landscape Recovery

Creator:: Kooistra, Chad M.
Abstract:: Forest disturbances, such as wildfires, pine beetle outbreaks, and floods are important features of many landscapes and ecosystems. Many disturbances are increasing in size, frequency, and intensity due to changing climates and land management decisions. The changing ecological and aesthetic conditions following a disturbance can lead to negative short- and...

Comparing Ectomycorrhizal Communities of Understory Giant Chinquapin (Chrysolepis chrysophylla) and Overstory Pinaceae Trees in a Mixed Conifer Forest in Central Oregon

Creator:: Longway, Lucas J.
Abstract:: Giant chinquapin (Chrysolepis chrysophylla) is an evergreen hardwood often found as a shrubby understory component of coniferous forests in the Pacific Northwest United States. Due to its ability to sprout quickly after disturbances such as fire and logging it is often viewed as a pest by forest managers. Like its...

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...

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...

Vertical structure and aboveground biomass of tropical forests from lidar remote sensing

Creator:: Gonçalves, Fabio Guimarães
Abstract:: Methods for obtaining accurate, spatially explicit estimates of biomass density in tropical forests are required to reduce uncertainties in the global carbon cycle, and to support international climate agreements and emerging carbon markets. Three-dimensional (3-D) remote sensing techniques sensitive to the vertical structure of vegetation provide a unique opportunity for...

Overexpression of the GROWTH REGULATING FACTOR 4-GRF-INTERACTING FACTOR 1 Transcription Factor Chimera Modifies Transformation and Regeneration Efficiency in Populus and Eucalyptus

Creator:: Ryan, Nathaniel W.
Abstract:: Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...

Regional dynamics of forest canopy change and underlying causal processes in the contiguous U.S.

Creator:: Schleeweis, Karen, Goward, Samuel N., Huang, Chengquan, Masek, Jeffrey G., Moisen, Gretchen, Kennedy, Robert E., and Thomas, Nancy E.
Abstract:: The history of forest change processes is written into forest age and distribution and affects earth systems at many scales. No one data set has been able to capture the full forest disturbance and land use record through time, so in this study, we combined multiple lines of evidence to...
