Response of the nitrogen-fixing lichen Lobaria pulmonaria to phosphorus, molybdenum, and vanadium

Creator:: Marks, Jade A., Pett-Ridge, Julie C., Perakis, Steven S., Allen, Jessica L., and McCune, Bruce
Abstract:: Nitrogen-fixing lichens (cyanolichens) are an important source of nitrogen (N) in Pacific Northwest forests, but limitation of lichen growth by elements essential for N fixation is poorly understood. To investigate how nutrient limitation may affect cyanolichen growth rates, we fertilized a tripartite cyanobacterial lichen (Lobaria pulmonaria) and a green algal...

Altered precipitation regime affects the function and composition of soil microbial communities on multiple time scales

Creator:: Zeglin, L. H., Bottomley, Peter J., Jumpponen, A., Rice, C. W., Arango, M., Lindsley, A., McGowan, A., Mfombep, P., and Myrold, D. D.
Abstract:: Climate change models predict that future precipitation patterns will entail lower-frequency but larger rainfall events, increasing the duration of dry soil conditions. Resulting shifts in microbial C cycling activity could affect soil C storage. Further, microbial response to rainfall events may be constrained by the physiological or nutrient limitation stress...

Short-term responses of native bees to livestock and implications for managing ecosystem services in grasslands

Creator:: Kimoto, Chiho, DeBano, Sandra J., Thorp, Robbin W., Taylor, Robert V., Schmalz, Heidi, DelCurto, Timothy, Johnson, Tracey, Kennedy, Patricia L., and Rao, Sujaya
Abstract:: Rangelands are significant providers of ecosystem services in agroecosystems world‐wide. Yet few studies have investigated how different intensities of livestock grazing impact one important provider of these ecosystem services—native bees. We conducted the first large‐scale manipulative study on the effect of a gradient of livestock grazing intensities on native bees...

Development of a 10,000 Locus Genetic Map of the Sunflower Genome Based on Multiple Crosses

Creator:: Bowers, John E., Bachlava, Eleni, Brunick, Robert L., Rieseberg, Loren H., Knapp, Steven J., and Burke, John M.
Abstract:: Genetic linkage maps have the potential to facilitate the genetic dissection of complex traits and comparative analyses of genome structure, as well as molecular breeding efforts in species of agronomic importance. Until recently, the majority of such maps was based on relatively low-throughput marker technologies, which limited marker density across...

Bumble Bee (Hymenoptera: Apidae) Foraging Distance and Colony Density Associated With a Late-Season Mass Flowering Crop

Creator:: Rao, Sujaya and Strange, James P.
Abstract:: Foraging behaviors of bumble bee workers have been examined in natural habitats, whereas agricultural landscapes, which can provide insights on flight distances to fragmented patches of bloom, have received limited attention. In particular, information on worker flight distances to crops blooming several months after nests have been established is invaluable....

Location of the Mechanism of Resistance to Amphorophora agathonica (Hemiptera: Aphididae) in Red Raspberry

Creator:: Lightle, D. M., Dossett, M., Backus, E. A., and Lee, J. C.
Abstract:: The aphid Amphorophora agathonica Hottes (Hemiptera: Aphididae) is an important virus vector in red (Rubus idaeus L.) and black (Rubus occidentalis L.) raspberries in North America. Raspberry resistance to A. agathonica in the form of a single dominant gene named Ag1 has been relied upon to help control aphid-transmitted plant...

Evaluation of Monitoring Traps for Drosophila suzukii (Diptera: Drosophilidae) in North America

Creator:: Lee, Jana C., Burrack, Hannah J., Barrantes, Luz D., Beers, Elizabeth H., Dreves, Amy J., Hamby, Kelly A., Haviland, David R., Isaacs, Rufus, Richardson, Tamara A., Shearer, Peter W., Stanley, Cory A., Walsh, Doug B., Walton, Vaughn M., Zalom, Frank G., and Bruck, Denny J.
Abstract:: Drosophila suzukii Matsumura (Diptera: Drosophilidae), a recent invasive pest of small and stone fruits, has been detected in more than half of the U.S. states, and in Canada, Mexico, and Europe. Upon discovery, several different trap designs were recommended for monitoring. This study compared the trap designs across seven states/provinces...

Table Beet Yield and Boron Deficiency as Influenced by Lime, Nitrogen, and Boron

Creator:: Hemphill, Delbert D. Jr, Weber, Michael S., and Jackson, T. L. (Thomas Lloyd), 1922-
Abstract:: Yield, occurrence of root canker (B deficiency), and leaf nutrient concentrations of the Morse strain of ‘Detroit Dark Red’ table beet (Beta vulgaris L.) as influenced by combinations of lime and N, B, and P fertilizers were evaluated in three studies. Greatest total yields and most favorable distribution of root...

Potential for Phosphorus Toxicity in Zinc-Stressed Corn and Potato

Creator:: Christensen, Neil Walter, 1944- and Jackson, T. L. (Thomas Lloyd), 1922-
Abstract:: Corn (Zea mays L., 'Illinois WF 9x38-11') and potato (Solanum tuberosum L., 'Russet Burbank') were grown in dithizone purified nutrient solutions to contrast relationships between dry matter yield, tissue phosphorus (P) concentration, and tissue zinc (Zn) concentration as they influence the development of Zn deficiency and P toxicity. Treatments consisted...

Delayed Glyphosate Application for No-Till Fallow in the Driest Region of the Inland Pacific Northwest

Creator:: Lutcher, Larry K.
Abstract:: Farmers typically use three applications of glyphosate to control weeds in no-till fallow. Some are now experimenting with an unconventional modification to this widely used approach. This modified approach is based on an intentional delay in the time of the first spraying. Farmers delay their first spraying because they want...
