Ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae)

Creator:: Campanella, Donald M.
Abstract:: A study consisting of three parts was undertaken to investigate how variation in species interactions, population genetic structure, epidemiological parameters, and plant breeding system may influence the ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae). Interactions between natural enemy species may modify their net effect on...

Emerging semantics to link phenotype and environment

Creator:: Thessen, Anne E., Bunkers, Daniel E., Buttigieg, Pier Luigi, Cooper, Laurel D., Dahdul, Wasila M., Domisch, Sami, Franz, Nico M., Jaiswal, Pankaj, Lawrence-Dill, Carolyn J., Midford, Peter E., Mungall, Christopher J., Ramírez, Martín J., Specht, Chelsea D., Vogt, Lars, Aldo Vos, Rutger, Walls, Ramona L., White, Jeffrey W., Zhang, Guanyang, Deans, Andrew R., Huala, Eva, Lewis, Suzanna E., and Mabee, Paula M.
Abstract:: Understanding the interplay between environmental conditions and phenotypes is a fundamental goal of biology. Unfortunately, data that include observations on phenotype and environment are highly heterogeneous and thus difficult to find and integrate. One approach that is likely to improve the status quo involves the use of ontologies to standardize...

An evaluation of the invasion potential of Kochia prostrata (forage kochia) in southwestern Idaho, USA

Creator:: Gray, Erin C.
Abstract:: Purposeful introductions of exotic species for rehabilitation efforts following wildfire are common on rangelands in the western U.S., though potential ecological impacts of introduced species in novel environments are often poorly understood. One such introduced species, Kochia prostrata (L.) Schrad (forage kochia) has been seeded on over 200,000 ha throughout...

Yield responses of invasive grasses to carbon doses

Creator:: Brunson, Jessi L.
Abstract:: The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...

2006 Integrated pest management resource guide

Creator:: Jepson, Paul C., Brewer, Linda J., Jepson, Susan B., and Oregon State University. Extension Service
Abstract:: This publication is offered as a reference to Integrated Pest Management (IPM) resources available to Oregon growers. It highlights university, federal, state, and private services and resources that provide support to growers in the implementation of IPM programs. The Guide consists of five sections: • An introduction to the National...

Efficacy and host specificity compared between two populations of the psyllid Aphalara itadori, candidates for biological control of invasive knotweeds in North America

Creator:: Grevstad, Fritzi, Shaw, Richard, Bourchier, Robert, Sanguankeo, Paolo, Cortat, Ghislaine, and Reardon, Richard C.
Abstract:: Invasive knotweeds are large perennial herbs in the Polygonaceae in the genus Fallopia that are native to Asia and invasive in North America. They include Fallopia japonica (Japanese knotweed), F. sachalinensis (giant knotweed), and a hybrid species F. x bohemica (Bohemian knotweed). Widespread throughout the continent and difficult to control...

Survey of the Beneficial and Pest Insect Fauna from Integrated Production and Non-Integrated Production Vineyards in the Willamette Region

Creator:: Viguers, Leslie and Fisher, J. R.
Abstract:: The wine grape industry is rapidly growing in Oregon. By the year 2005, we could predict that Oregon will have over 10,000 acres in wine grape production. At a meeting last year, the Grapevine Improvement Committee acknowledged that little was known about the presence of potential pest and beneficial insects...

Responses of Pacific Northwest prairies to soil nutrient manipulations : implications for restoration of Castilleja levisecta and control of invasive species

Creator:: Lawrence, Caitlin E.
Abstract:: Pacific Northwest prairies have become significantly reduced in extent, and in the Willamette Valley of Oregon, less than one percent of native upland prairies remain. Many species have been impacted by this extreme loss of habitat, including Castilleja levisecta (golden paintbrush), a threatened hemiparasitic forb species endemic to the Pacific...

Why pest plant control and native plant establishment failed : a restoration autopsy

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., Clark, Deborah Louise, 1950-, and Wilson, Mark G.
Abstract:: Explaining restoration failure can be as important as touting success. We used a series of studies to understand the failure of techniques commonly used to restore wetland prairies in the Willamette Valley of western Oregon. Burning, fallowing, and solarization (covering tilled plots with plastic sheeting to heat the soil) had...
