Green Revolution Trees: Semidwarfism Transgenes Modify Gibberellins, Promote Root Growth, Enhance Morphological Diversity, and Reduce Competitiveness in Hybrid Poplar

Creator:: Elias, Ani A., Busov, Victor B., Kosola, Kevin R., Ma, Cathleen, Etherington, Elizabeth, Shevchenko, Olga, Gandhi, Harish, Pearce, David W., Rood, Stewart B., and Strauss, Steven H.
Abstract:: Semidwarfism has been used extensively in row crops and horticulture to promote yield, reduce lodging, and improve harvest index, and it might have similar benefits for trees for short-rotation forestry or energy plantations, reclamation, phytoremediation, or other applications. We studied the effects of the dominant semidwarfism transgenes GA Insensitive (GAI)...

Assessing the Carbon Consequences of Western Juniper (Juniperus occidentalis) Encroachment Across Oregon, USA

Creator:: Campbell, John L., Kennedy, Robert E., Cohen, Warren B., and Miller, Richard F.
Abstract:: Our ability to assess the continental impacts of woody encroachment remains compromised by the paucity of studies quantifying regional encroachment rates. This knowledge gap is especially apparent when it comes to quantifying the impact of woody encroachment on large-scale carbon dynamics. In this study, we use a combination of aerial...

Ten-year growth and mortality in young Douglas-fir stands experiencing a range in Swiss needle cast severity

Creator:: Maguire, Douglas A., Mainwaring, Douglas B., and Kanaskie, Alan
Abstract:: Swiss needle cast, a foliar disease caused by the Ascomycete Phaeocryptopus gaeumannii (T. Rohde) Petr., continues to afflict Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in north coastal Oregon. Permanent plots were installed in 1998 to assess growth impacts and monitor disease severity. Gross periodic annual increment was measured for three 2-year...

Effects of bison on willow and cottonwood in northern Yellowstone National Park

Creator:: Painter, Luke E. and Ripple, William J.
Abstract:: On the northern ungulate winter range of Yellowstone Park, willow (Salix spp.) and cottonwood (Populus angustifolia and P. balsamifera) have increased in height and cover in some places since the reintroduction of wolves (Canis lupus) and the subsequent changes in elk (Cervus elaphus) behavior and population densities. However, in the...

Berry-producing shrub characteristics following wolf reintroduction in Yellowstone National Park

Creator:: Beschta, Robert L. and Ripple, William J.
Abstract:: Gray wolves (Canis lupus) were reintroduced into Yellowstone National Park in 1995-96, thus completing the park’s large predator guild. In the fall of 2010, approximately 15 years after wolf reintroduction, we sampled ten genera/species of berry-producing shrubs within 97 aspen (Populus tremuloides) stands in the park’s northern ungulate winter range....

Seasonal variation of photosynthetic model parameters and leaf area index from global Fluxnet eddy covariance data

Creator:: Groenendijk, M., Dolman, A. J., Ammann, C., Arneth, A., Cescatti, A., Dragoni, D., Gash, J. H. C., Gianelle, D., Gioli, B., Kiely, G., Knohl, A., Law, B. E., Lund, M., Marcolla, B., van der Molen, M. K., Montagnani, L., Moors, E., Richardson, A. D., Roupsard, O., Verbeeck, H., and Wohlfahrt, G.
Abstract:: Global vegetation models require the photosynthetic parameters, maximum carboxylation capacity (V[subscript cm]), and quantum yield (alpha) to parameterize their plant functional types (PFTs). The purpose of this work is to determine how much the scaling of the parameters from leaf to ecosystem level through a seasonally varying leaf area index...

Environment and shoot growth of woody plants

Creator:: Lavender, Denis P. and Oregon State University. Forest Research Laboratory
Abstract:: Perennial woody plants have a complex annual cycle keyed to the environment. Temperate plants have an annual dormant period commonly broken by exposure to low temperatures, although daily photoperiods of 16 hours or longer may partially substitute for the chilling. Shoot growth in the spring is normally stimulated by rising...

Initial experimental effects of intensive forest management on avian abundance

Creator:: Betts, Matthew G., Verschuyl, Jake, Giovanini, Jack, Stokely, Thomas D., and Kroll, Andrew J.
Abstract:: Components of biodiversity in intensively managed forest stands may be reduced in comparison to naturally regenerated stands. Use of herbicides to suppress herbaceous and woody plant species that compete with planted seedlings has been implicated in negative impacts. We designed a large-scale experimental study to test the influence of intensive...

Riparian forest buffers on agricultural lands in the Oregon coast range : Beaver Creek riparian project as a case study

Creator:: Bishaw, Badege, Emmingham, William H., Rogers, William Reinhold, and Oregon State University. Forest Research Laboratory
Abstract:: Riparian areas in the Pacific Northwest have traditionally been a source of natural resources, such as timber and grazing, and have been used as transportation corridors and homestead sites. A primary impact of use has been the removal of riparian trees, the crowns and roots of which provide shade and...
