Evaluation of transgenes for stress tolerance, lignin modification, and growth enhancement in poplar

Creator:: Elias, Ani Anna
Abstract:: We evaluated genes previously identified from a large scale functional genomics screen for their potential value to help enhance carbon sequestration in planted trees. We used poplar as a model tree species because of its abundant genetic variation, ease of gene transfer, and availability of large databases for genomic, anatomical,...

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...

Decadal Trends in Net Ecosystem Production and Net Ecosystem Carbon Balance for a Regional Socioecological System

Creator:: Turner, David P., Ritts, William D., Yang, Zhiqiang, Kennedy, Robert E., Cohen, Warren B., Duane, Maureen V., Thornton, Peter E., and Law, Beverly E.
Abstract:: Carbon sequestration is increasingly recognized as an ecosystem service, and forest management has a large potential to alter regional carbon fluxes − notably by way of harvest removals and related impacts on net ecosystem production (NEP). In the Pacific Northwest region of the U.S., the implementation of the Northwest Forest...

Growth, morphology, and in vitro development of transgenic poplars with RNAi-inhibited PtDDM1-1/2 gene expression

Creator:: Zhu, Ruoqing
Abstract:: Epigenetic mechanisms are important for control of plant development, and may play a particularly important role in trees given their long life cycles and distinctive and stable tissue types. To help understand the role of epigenetics in tree development, we produced transgenic poplars with reduced activity of the DDM1 genes,...

Remote sensing of forest biomass dynamics using Landsat-derived disturbance and recovery history and lidar data

Creator:: Pflugmacher, Dirk
Abstract:: Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...

Comparison and assessment of coarse resolution land cover maps for Northern Eurasia

Creator:: Pflugmacher, Dirk, Krankina, Olga N., Cohen, Warren B., Friedl, Mark A., Sulla-Menashe, Damien, Kennedy, Robert E., Nelson, Peder, Loboda, Tatiana V., Kuemmerle, Tobias, Dyukarev, Egor, Elsakov, Vladimir, and Kharuk, Viacheslav I.
Abstract:: Information on land cover at global and continental scales is critical for addressing a range of ecological, socioeconomic and policy questions. Global land cover maps have evolved rapidly in the last decade, but efforts to evaluate map uncertainties have been limited, especially in remote areas like Northern Eurasia. Northern Eurasia...

Mesoscale Variation in Snag and Hardwood Densities and Sizes in Old-Growth Forests in Western Oregon

Creator:: Ares, Adrian, Bright, Cheryl, and Puettmann, Klaus
Abstract:: Snags and hardwoods contribute to biological, structural, and functional diversity in old-growth forests. In the US Pacific Northwest, only general knowledge about regional patterns is available to determine target density of snags and hardwood trees. To investigate their variability at relevant scales for silviculture, we examined snag and hardwood densities...

Carbon concentration of standing and downed woody detritus: Effects of tree taxa, decay class, position, and tissue type

Creator:: Harmon, Mark E., Fasth, Becky, Woodall, Christopher W., and Sexton, Jay
Abstract:: The degree to which carbon concentration (CC) of woody detritus varies by tree taxa, stage of decay, tissue type (i.e., bark versus wood), and vertical orientation was examined in samples of 60 tree species from the Northern Hemisphere. The mean CC of 257 study samples was 49.3% with a range...

Forest wildfire, fuel reduction treatments, and landscape carbon stocks: A sensitivity analysis

Creator:: Campbell, John L. and Ager, Alan A.
Abstract:: Fuel reduction treatments prescribed in fire-suppressed forests of western North America pose an apparent paradox with respect to terrestrial carbon management. Such treatments have the immediate effect of reducing forest carbon stocks but likely reduce future carbon losses through the combustion and mortality caused by high-severity wildfires. Assessing the long-term...

Ecological Forestry : A Critical Analysis

Creator:: Batavia, Chelsea
Abstract:: Although science is widely accepted as a fundamental source of information underlying decisions about forest management and conservation, considerably less attention has been paid to the inevitable role that normative values and beliefs play in such decisions. This thesis highlights the normative dimensions of "ecological forestry," a strategy of forest...
