Grassland Response to Herbicides and Seeding of Native Grasses 6 Years Posttreatment

Creator:: Endress, Bryan A., Parks, Catherine G., Naylor, Bridgett J., Radosevich, Steven R., and Porter, Mark
Abstract:: Herbicides are the primary method used to control exotic, invasive plants. This study evaluated restoration efforts applied to grasslands dominated by an invasive plant, sulfur cinquefoil, 6 yr after treatments. Of the five herbicides we evaluated, picloram continued to provide the best control of sulfur cinquefoil over 6 yr. We...

Public Involvement in Natural Resource Decision Making: Goals, Methodology, and Evaluation

Creator:: Lawrence, Rick L. and Daniels, Steven E.
Abstract:: This paper provides a primer on research in the field of public involvement in natural resource decision making. Previous studies are synthesized and organized into three areas: (1 ) goals of public involvement, (2) principles related to implementing public involvement programs, and (3) evaluation of public involvement methods. A bibliography...

High frequency transformation of cottonwoods (genus Populus) by Agrobacterium rhizogene

Creator:: Han, Kyung-Hwan, Gordon, Milton P., and Strauss, Steven H.
Abstract:: Many species of Populus, particularly cottonwoods of sections Aigeiros and Tacamahaca, remain recalcitrant to genetic transformation. We demonstrate that transgenic trees can be readily produced in several poplar genotypes using wild-type Agrobacterium rhizogenes. Hairy roots were produced in a variety of clones that included Populus trichocarpa Torr. & A. Gray,...

Influence of species proportion and timing of establishment on stem quality in mixed red alder – Douglas-fir plantations

Creator:: Grotta, Amy T., Gartner, Barbara L., and Radosevich, Steven R.
Abstract:: The relationships among stand structure, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) branch characteristics, and red alder (Alnus rubra (Bong.)) stem form attributes were explored for 10- to 15-year-old trees growing in mixed Douglas-fir – red alder plantations. Treatments included a range of species proportions, and red alder was either planted simultaneously...

Structure and yield of two-aged stands on the Willamette National Forest, Oregon: implications for green tree retention

Creator:: Acker, Steven A., Zenner, E. K., and Emmingham, W. H.
Abstract:: Green tree retention, a practice based on ecosystem science, has been integrated into forest management as a working hypothesis, requiring research and monitoring to quantify its effects. We undertook a retrospective study of natural, two-aged forest stands on the Willamette National Forest to provide preliminary estimates of the effects of...

Epigenetic regulation of adaptive responses of forest tree species to the environment

Creator:: Braeutigam, Katharina, Vining, Kelly J., Lafon-Placette, Clement, Fossdal, Carl G., Mirouze, Marie, Gutierrez Marcos, Jose, Fluch, Silvia, Fernandez Fraga, Mario, Angeles Guevara, M., Abarca, Dolores, Johnsen, Oystein, Maury, Stephane, Strauss, Steven H., Campbell, Malcolm M., Rohde, Antje, Diaz-Sala, Carmen, and Cervera, Maria-Teresa
Abstract:: Epigenetic variation is likely to contribute to the phenotypic plasticity and adaptative capacity of plant species, and may be especially important for long-lived organisms with complex life cycles, including forest trees. Diverse environmental stresses and hybridization/polyploidization events can create reversible heritable epigenetic marks that can be transmitted to subsequent generations...

The hydrology of the humid tropics

Creator:: Wohl, Ellen, Barros, Ana, Brunsell, Nathaniel, Chappell, Nick A., Coe, Michael, Giambelluca, Thomas, Goldsmith, Steven, Harmon, Russell, Hendrickx, Jan M. H., Juvik, James, McDonnell, Jeffrey, and Ogden, Fred
Abstract:: Hydrological processes in the humid tropics differ from other regions in having greater energy inputs and faster rates of change, including human-induced change. Human influences on population growth, land use and climate change will profoundly influence tropical hydrology, yet understanding of key hydrological interactions is limited. We propose that efforts...

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)...

Genome resequencing reveals multiscale geographic structure and extensive linkage disequilibrium in the forest tree Populus trichocarpa

Creator:: Slavov, Gancho T., DiFazio, Stephen P., Martin, Joel, Schackwitz, Wendy, Muchero, Wellington, Rodgers-Melnick, Eli, Lipphardt, Mindie F., Pennacchio, Christa P., Hellsten, Uffe, Pennacchio, Len A., Gunter, Lee E., Ranjan, Priya, Vining, Kelly, Pomraning, Kyle R., Wilhelm, Larry J., Pellegrini, Matteo, Mockler, Todd C., Freitag, Michael, Geraldes, Armando, El-Kassaby, Yousry A., Mansfield, Shawn D., Cronk, Quentin C. B., Douglas, Carl J., Strauss, Steven H., Rokhsar, Dan, and Tuskan, Gerald A.
Abstract:: •Plant population genomics informs evolutionary biology, breeding, conservation and bioenergy feedstock development. For example, the detection of reliable phenotype–genotype associations and molecular signatures of selection requires a detailed knowledge about genome-wide patterns of allele frequency variation, linkage disequilibrium and recombination. •We resequenced 16 genomes of the model tree Populus trichocarpa...
