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...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Isotopic composition of respired CO2 in a small watershed : development and testing of an automated sampling system and analysis of first year data

Creator:: Hauck, Mark J.
Abstract:: Warming of the terrestrial biosphere due to the anthropogenic addition of carbon dioxide to the earth’s atmosphere is becoming a major focus of scientific inquiry. Predictions of the extent of this warming are hampered by uncertainty in the ability of the earth’s ecosystems to counteract this effect by sequestering carbon...

Distinguishing between live and dead standing tree biomass on the North Rim of Grand Canyon National Park, USA using small-footprint lidar data

Creator:: Kim, YunSuk
Abstract:: Accurate estimation of live and dead biomass in forested ecosystems is important for studies of carbon dynamics, biodiversity, and wildfire behavior, and for forest management. Lidar remote sensing has been used successfully to estimate live biomass, but studies focusing on dead biomass are rare. We used lidar data, in conjunction...

Understanding changes in forest cover and carbon storage in early successional forests of the Pacific Northwest using USDA Forest Service FIA and multi-temporal Landsat data

Creator:: Schroeder, Todd A.
Abstract:: To effectively study dynamic processes like forest succession over long time periods one must effectively integrate data collected at many different times, locations and spatial scales. The purpose of this research is to integrate forest inventory data collected by the USDA Forest Service’s Forest Inventory and Analysis (FIA) Program with...

Patterns of tree establishment and vegetation composition in relation to climate and topography of a subalpine meadow landscape, Jefferson Park, Oregon, USA

Creator:: Zald, Harold S. J.
Abstract:: The forest alpine tundra ecotone (FTE, also known as alpine treeline or subalpine parkland), is a conspicuous feature of mountain landscapes throughout the world. Climate change-driven increases in temperature are believed to result in FTE movement and tree invasion of subalpine meadows, which have been documented throughout the Northern Hemisphere...

Climate, management, and forest type influences on carbon dynamics of West-Coast US forests

Creator:: Hudiburg, Tara M.
Abstract:: Net uptake of carbon from the atmosphere (net ecosystem production, NEP) is dependent on climate, disturbance history, management practices, forest age, and forest type. To improve understanding of the influence of these factors on forest carbon flux in the western U.S., a combination of federal inventory data and supplemental ground...

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...

The methodology, implementation, and analysis of the isotopic composition of soil respired CO₂ in forest ecological research

Creator:: Kayler, Zachary Eric
Abstract:: Soils are the largest terrestrial pool of carbon, therefore it is critical to understand what controls soil carbon efflux to the atmosphere in light of current climate uncertainty. The primary efflux of carbon from soil is soil respiration which is typically categorized into autotrophic and heterotrophic respiration. These two components...

Development of a hybrid modeling framework for intensively managed Douglas-fir plantations in the Pacific Northwest

Creator:: Weiskittel, Aaron R.
Abstract:: Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insufficient...
