Secondary Metabolism and Interspecific Competition Affect Accumulation of Spontaneous Mutants in the GacS-GacA Regulatory System in Pseudomonas protegens

Creator:: Yan, Qing, Lopes, Lucas D., Shaffer, Brenda T., Kidarsa, Teresa A., Vining, Oliver, Philmus, Benjamin, Song, Chunxu, Stockwell, Virginia O., Raaijmakers, Jos M., McPhail, Kerry L., Andreote, Fernando D., Chang, Jeff H., and Loper, Joyce E.
Abstract:: Secondary metabolites are synthesized by many microorganisms and provide a fitness benefit in the presence of competitors and predators. Secondary metabolism also can be costly, as it shunts energy and intermediates from primary metabolism. In Pseudomonas spp., secondary metabolism is controlled by the GacS-GacA global regulatory system. Intriguingly, spontaneous mutations...

Project Happy Apples: Assisting Backyard Growers in Codling Moth Management

Creator:: Detweiler, Amy Jo and Stephan, Toni
Abstract:: Project Happy Apples began as an effort to assist backyard growers in managing codling moth in their fruit trees. We developed a process using emails and a web page to provide timely information related to the life cycle of codling moth and relevant integrated pest management (IPM) strategies. The content...

The Effect of Novel Research Activities on Long-term Survival of Temporarily Captive Steller Sea Lions (Eumetopias jubatus)

Creator:: Shuert, Courtney, Horning, Markus, and Mellish, Jo-Ann
Abstract:: Two novel research approaches were developed to facilitate controlled access to, and long-term monitoring of, juvenile Steller sea lions for periods longer than typically afforded by traditional fieldwork. The Transient Juvenile Steller sea lion Project at the Alaska SeaLife Center facilitated nutritional, physiological, and behavioral studies on the platform of...

Muscle Segment Homeobox Genes Direct Embryonic Diapause by Limiting Inflammation in the Uterus

Creator:: Cha, Jeeyeon, Burnum-Johnson, Kristin E., Bartos, Amanda, Li, Yingju, Baker, Erin S., Tilton, Susan C., Webb-Robertson, Bobbie-Jo M., Piehowski, Paul D., Monroe, Matthew E., Jegga, Anil G., Murata, Shigeo, Hirota, Yasushi, and Dey, Sudhansu K.
Abstract:: Embryonic diapause is a reproductive strategy widespread in the animal kingdom. This phenomenon is defined by a temporary arrest in blastocyst growth and metabolic activity within a quiescent uterus without implantation until the environmental and maternal milieu become favorable for pregnancy to progress. We found that uterine Msx expression persists...

A doubled down invasion of the northeast Pacific by the Asian mud shrimp, Upogebia major and its coevolved bopyrid isopod parasite, Orthione griffenis

Creator:: Chapman, John W., Li, Jingchun, McGowan, Michael F., Breitenstein, Ralph A., Appy, Ralph, Hieb, Kathryn A., Piotrowski, Christina N., and Elder, Leanne E.
Abstract:: Dramatic declines of the native northeast Pacific mud shrimp, Upogebia pugettensis over the last three decades have occurred in response to intense infestations by the Asian bopyrid isopod parasite, Orthione griffenis, that was introduced in the 1980s. We report herein the arrival of the Asian mud shrimp, Upogebia major, in...

Diversity Literary Awards: A Tool for Assessing an Academic Library's Collection

Creator:: Kristick, Laurel L.
Abstract:: Diversity literary awards and other sources were used to create a list of high-quality titles written by and about underrepresented groups. This list was used to assess the diversity and inclusiveness of the library collections of a land-grant university. Gaps in the collection and acquisition processes were identified and will...

Dissolved Organic Carbon Production and Flux from Long Term Litter Manipulations in a Pacific Northwest Old-Growth Forest

Creator:: Evans, Lucas R.
Abstract:: Dissolved organic carbon (DOC) flux is an important mechanism to convey soil carbon (C) from aboveground organic debris (litter) to deeper soil horizons and can influence the formation of stable soil organic carbon (SOC) compounds. Aboveground litter quantity and quality was manipulated for 20-years in an old-growth Douglas fir forest...

An optical method for rapid examination of check development in decorative plywood panels

Creator:: Burnard, Michael David, Muszynski, Lech, Leavengood, Scott, and Ganio, Lisa
Abstract:: Common methods for assessment of surface checking in decorative plywood panels rely on manual handling and visual inspection of specimens, a laborious procedure practically limiting the number of materials and variables that may be considered within one project. In this study, a new automated optical method for detection and measurement...

Selective Laser Melting of H13 Tool Steel for Rapid Tooling

Creator:: Katancik, Michael
Abstract:: The current knowledge on the microstructural evolutions and mechanical properties of selective laser melting (SLM) produced H13 tool steel components is limited. This research is focused on optimization of SLM processing parameters for H13 tool steel and investigation of microstructure and mechanical properties of H13 tool steel components after SLM...
