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...

Mapping Migratory Bird Prevalence Using Remote Sensing Data Fusion

Creator:: Swatantran, Anu, Dubayah, Ralph, Goetz, Scott, Hofton, Michelle, Betts, Matthew G., Sun, Mindy, Simard, Marc, and Holmes, Richard
Abstract:: Background: Improved maps of species distributions are important for effective management of wildlife under increasing anthropogenic pressures. Recent advances in lidar and radar remote sensing have shown considerable potential for mapping forest structure and habitat characteristics across landscapes. However, their relative efficacies and integrated use in habitat mapping remain largely...

A Critical Time Window for Organismal Interactions in a Pelagic Ecosystem

Creator:: Benoit-Bird, Kelly J. and McManus, Margaret A.
Abstract:: To measure organismal coherence in a pelagic ecosystem, we used moored sensors to describe the vertical dynamics of each step in the food chain in shelf waters off the west shore of Oahu, Hawaii. Horizontally extensive, intense aggregations of phytoplankton, zooplankton, and micronekton exhibited strong diel patterns in abundance and...

First Direct Evidence for Natal Wintering Ground Fidelity and Estimate of Juvenile Survival in the New Zealand Southern Right Whale Eubalaena australis

Creator:: Carroll, E. L., Fewster, R. M., Childerhouse, S. J., Patenaude, N. J., Boren, L., and Baker, C. S.
Abstract:: Juvenile survival and recruitment can be more sensitive to environmental, ecological and anthropogenic factors than adult survival, influencing population-level processes like recruitment and growth rate in long-lived, iteroparous species such as southern right whales. Conventionally, Southern right whales are individually identified using callosity patterns, which do not stabilise until 6–12...

Mycobacterium avium Possesses Extracellular DNA that Contributes to Biofilm Formation, Structural Integrity, and Tolerance to Antibiotics

Creator:: Rose, Sasha J., Babrak, Lmar M., and Bermudez, Luiz E.
Abstract:: Mycobacterium avium subsp. hominissuis is an opportunistic pathogen that is associated with biofilm-related infections of the respiratory tract and is difficult to treat. In recent years, extracellular DNA (eDNA) has been found to be a major component of bacterial biofilms, including many pathogens involved in biofilm-associated infections. To date, eDNA...

Trends in Developed Land Cover Adjacent to Habitat for Threatened Salmon in Puget Sound, Washington, U.S.A.

Creator:: Bartz, Krista K., Ford, Michael J., Beechie, Timothy J., Fresh, Kurt L., Pess, George R., Kennedy, Robert E., Rowse, Melinda L., and Sheer, Mindi
Abstract:: For widely distributed species at risk, such as Pacific salmon (Oncorhynchus spp.), habitat monitoring is both essential and challenging. Only recently have widespread monitoring programs been implemented for salmon habitat in the Pacific Northwest. Remote sensing data, such as Landsat images, are therefore a useful way to evaluate trends prior...

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...

ARK: Aggregation of Reads by K-Means for Estimation of Bacterial Community Composition

Creator:: Koslicki, David, Chatterjee, Saikat, Shahrivar, Damon, Walker, Alan W., Francis, Suzanna C., Fraser, Louise J., Vehkaperä, Mikko, Lan, Yueheng, and Corander, Jukka
Abstract:: Motivation: Estimation of bacterial community composition from high-throughput sequenced 16S rRNA gene amplicons is a key task in microbial ecology. Since the sequence data from each sample typically consist of a large number of reads and are adversely impacted by different levels of biological and technical noise, accurate analysis of...

Ocean Acidification Has Multiple Modes of Action on Bivalve Larvae

Creator:: Waldbusser, George G., Hales, Burke, Langdon, Chris J., Haley, Brian A., Schrader, Paul, Brunner, Elizabeth L., Gray, Matthew W., Miller, Cale A., Gimenez, Iria, and Hutchinson, Greg
Abstract:: Ocean acidification (OA) is altering the chemistry of the world’s oceans at rates unparalleled in the past roughly 1 million years. Understanding the impacts of this rapid change in baseline carbonate chemistry on marine organisms needs a precise, mechanistic understanding of physiological responses to carbonate chemistry. Recent experimental work has...

Selenium and Selenoprotein Deficiencies Induce Widespread Pyogranuloma Formation in Mice, while High Levels of Dietary Selenium Decrease Liver Tumor Size Driven by TGFα

Creator:: Moustafa, Mohamed E., Carlson, Bradley A., Anver, Miriam R., Bobe, Gerd, Zhong, Nianxin, Ward, Jerrold M., Perella, Christine M., Hoffmann, Victoria J., Rogers, Keith, Combs, Gerald F., Jr., Schweizer, Ulrich, Merlino, Glenn, Gladyshev, Vadim N., and Hatfield, Dolph L.
Abstract:: Changes in dietary selenium and selenoprotein status may influence both anti- and pro-cancer pathways, making the outcome of interventions different from one study to another. To characterize such outcomes in a defined setting, we undertook a controlled hepatocarcinogenesis study involving varying levels of dietary selenium and altered selenoprotein status using...
