Ultraviolet Radiation Influences Perch Selection by a Neotropical Poison-Dart Frog

Creator:: Kats, Lee B., Bucciarelli, Gary M., Schlais, David E., Blaustein, Andrew R., and Han, Barbara A.
Abstract:: Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...

Mechanistic Insights into Validoxylamine A 7’-Phosphate Synthesis by VldE Using the Structure of the Entire Product Complex

Creator:: Cavalier, Michael C., Yim, Young-Sun, Asamizu, Shumpei, Neau, David, Almabruk, Khaled H., Mahmud, Taifo, and Lee, Yong-Hwan
Abstract:: The pseudo-glycosyltransferase VldE catalyzes non-glycosidic C-N coupling between an unsaturated cyclitol and a saturated aminocyclitol with the conservation of the stereochemical configuration of the substrates to form validoxylamine A 7'-phosphate, the biosynthetic precursor of the antibiotic validamycin A. To study the molecular basis of its mechanism, the three-dimensional structures of...

Potential Therapeutic Competition in Community-Living Older Adults in the U.S.: Use of Medications That May Adversely Affect a Coexisting Condition

Creator:: Lorgunpai, Songprod Jonathan, Grammas, Marianthe, Lee, David S. H., McAvay, Gail, Charpentier, Peter, and Tinetti, Mary E.
Abstract:: OBJECTIVE: The 75% of older adults with multiple chronic conditions are at risk of therapeutic competition (i.e. treatment for one condition may adversely affect a coexisting condition). The objective was to determine the prevalence of potential therapeutic competition in community-living older adults. METHODS: Cross-sectional descriptive study of a representative sample...

Biotic and abiotic factors impacting development, behavior, phenology, and reproductive biology of Drosophila suzukii

Creator:: Hamby, Kelly A., Bellamy, David E., Chiu, Joanna C., Lee, Jana C., Walton, Vaughn M., Wiman, Nik G., York, Riki M., and Biondi, Antonio
Abstract:: Spotted wing drosophila, Drosophila suzukii, is a devastating invasive pest of small and stone fruits in the Americas and Europe. To better understand the population dynamics of D. suzukii, we reviewed recent work on juvenile development, adult reproduction, and seasonal variation in life history parameters including the abiotic/biotic factors that...

Anti-Hypertensive Medications and Cardiovascular Events in Older Adults with Multiple Chronic Conditions

Creator:: Tinetti, Mary E., Han, Ling, McAvay, Gail J., Lee, David S. H., Peduzzi, Peter, Dodson, John A., Gross, Cary P., Zhou, Bingqing, and Lin, Haiqun
Abstract:: Importance Randomized trials of anti-hypertensive treatment demonstrating reduced risk of cardiovascular events in older adults included participants with less comorbidity than clinical populations. Whether these results generalize to all older adults, most of whom have multiple chronic conditions, is uncertain. Objective To determine the association between anti-hypertensive medications and CV...

Factors Controlling Soil Microbial Biomass and Bacterial Diversity and Community Composition in a Cold Desert Ecosystem: Role of Geographic Scale

Creator:: Van Horn, David J., Van Horn, M. Lee, Barrett, John E., Gooseff, Michael N., Altrichter, Adam E., Geyer, Kevin M., Zeglin, Lydia H., and Takacs-Vesbach, Cristina D.
Abstract:: Understanding controls over the distribution of soil bacteria is a fundamental Understanding controls over the distribution of soil bacteria is a fundamental step toward describing soil ecosystems, understanding their functional capabilities, and predicting their responses to environmental change. This study investigated the controls on the biomass, species richness, and community...

Prescribed fire effects on resource selection by cattle in mesic sagebrush steppe. Part 1: Spring grazing

Creator:: Clark, Patrick E., Lee, Jaechoul, Ko, Kyungduk, Nielson, Ryan M., Johnson, Douglas E., Ganskopp, David C., Chigbrow, Joe, Pierson, Fredrick B., and Hardegree, Stuart P.
Abstract:: Prescribed fire is commonly applied world-wide as a tool for enhancing habitats and altering resource-selection patterns of grazing animals. A scientific basis for this practice has been established in some ecosystems but its efficacy has not been rigorously evaluated on mesic sagebrush steppe. Beginning in 2003, resource-selection patterns of beef...

Sources and Levels of Ambient Ocean Sound near the Antarctic Peninsula

Creator:: Dziak, Robert P., Bohnenstiehl, DelWayne R., Stafford, Kathleen M., Matsumoto, Haruyoshi, Park, Minkyu, Lee, Won Sang, Fowler, Matt J., Lau, Tai-Kwan, Haxel, Joseph H., and Mellinger, David K.
Abstract:: Arrays of hydrophones were deployed within the Bransfield Strait and Scotia Sea (Antarctic Peninsula region) from 2005 to 2009 to record ambient ocean sound at frequencies of up to 125 and 500 Hz. Icequakes, which are broadband, short duration signals derived from fracturing of large free-floating icebergs, are a prominent...

Phytophthora ramorum : a guide for Oregon nurseries

Creator:: Oregon State University. Extension Service, Parke, Jennifer Lee, Pscheidt, Jay William, and Linderman, R. G.
Abstract:: A newly described funguslike organism named Phytophthora ramorum was discovered in 1993 to cause leaf blight, stem canker, and tip dieback on nursery-grown rhododendrons and viburnums in Germany and the Netherlands. At about the same time, many tanoaks (Lithocarpus densiflorus) and oaks (Quercus sp.) in the San Francisco Bay Area...
