Evidence that summer jellyfish blooms impact Pacific Northwest salmon production

Creator:: Ruzicka, James J., Daly, Elizabeth A., and Brodeur, Richard D.
Abstract:: Interannual variability in salmon (Oncorhynchus spp.) production in the northeast Pacific is understood to be driven by oceanographic variability and bottom-up processes affecting prey availability to juvenile salmon. Scyphozoan jellyfish have an important role in shaping the pathways of energy flow through pelagic food webs. While jellyfish obtain high production...

Genome-Wide Profiling and Analysis of Arabidopsis siRNAs

Creator:: Kasschau, Kristin D., Fahlgren, Noah, Chapman, Elisabeth J., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., and Carrington, James C.
Abstract:: Eukaryotes contain a diversified set of small RNA-guided pathways that control genes, repeated sequences, and viruses at the transcriptional and posttranscriptional levels. Genome-wide profiles and analyses of small RNAs, particularly the large class of 24-nucleotide (nt) short interfering RNAs (siRNAs), were done for wild-type Arabidopsis thaliana and silencing pathway mutants...

The ERI-6/7 Helicase Acts at the First Stage of an siRNA Amplification Pathway That Targets Recent Gene Duplications

Creator:: Fischer, Sylvia E. J., Montgomery, Taiowa A., Zhang, Chi, Fahlgren, Noah, Breen, Peter C., Hwang, Alexia, Sullivan, Christopher M., Carrington, James C., and Ruvkun, Gary
Abstract:: Endogenous small interfering RNAs (siRNAs) are a class of naturally occuring regulatory RNAs found in fungi, plants, and animals. Some endogenous siRNAs are required to silence transposons or function in chromosome segregation; however, the specific roles of most endogenous siRNAs are unclear. The helicase gene eri-6/7 was identified in the...

Post-fire tree establishment and early cohort development in conifer forests of the western Cascades of Oregon, USA

Creator:: Tepley, Alan J., Swanson, Frederick J., and Spies, Thomas A.
Abstract:: Early‐seral ecosystems make important contributions to regional biodiversity by supporting high abundance and diversity of many plant and animal species that are otherwise rare or absent from closed‐canopy forests. Therefore, the period of post‐fire tree establishment is a key stage in forest stand and ecosystem development that can be viewed...

Aggregation of Sea Urchin Phagocytes Is Augmented In Vitro by Lipopolysaccharide

Creator:: Majeske, Audrey J., Bayne, Christopher J., and Smith, L. Courtney
Abstract:: Development of protocols and media for culturing immune cells from marine invertebrates has not kept pace with advancements in mammalian immune cell culture, the latter having been driven by the need to understand the causes of and develop therapies for human and animal diseases. However, expansion of the aquaculture industry...

Complete genome sequence of Nitrosomonas sp. Is79, an ammonia oxidizing bacterium adapted to low ammonium concentrations

Creator:: Bollmann, Annette, Sedlacek, Christopher J., Norton, Jeanette, Laanbroek, Hendrikus J., Suwa, Yuichi, Stein, Lisa Y., Klotz, Martin G., Arp, Daniel J., Sayavedra-Soto, Luis, Lu, Megan, Bruce, David, Detter, Chris, Tapia, Roxanne, Han, James, Woyke, Tanja, Pitluck, Sam, Pennacchio, Len, Nolan, Matt, Land, Miriam L., Huntemann, Marcel, Deshpande, Shweta, Han, Cliff, Chen, Amy, Kyrpides, Nikos, Movromatis, Konstantinos, Markowitz, Victor, Szeto, Ernest, Ivonova, Natalia, Mikhailova, Natalia, Pagani, Ioanna, Pati, Amrita, Peters, Lin, Ovchinnikova, Galina, Goodwin, Lynne A., and Lucas, Susan M.
Abstract:: Nitrosomonas sp. Is79 is a chemolithoautotrophic ammonia-oxidizing bacterium that belongs to the family Nitrosomonadaceae within the phylum Proteobacteria. Ammonia oxidation is the first step of nitrification, an important process in the global nitrogen cycle ultimately resulting in the production of nitrate. Nitrosomonas sp. Is79 is an ammonia oxidizer of high...

GRACE storage-runoff hystereses reveal the dynamics of regional watersheds

Creator:: Sproles, E. A., Leibowitz, S. G., Reager, J. T., Wigington, P. J., Jr., Famiglietti, J. S., and Patil, S. D.
Abstract:: We characterize how regional watersheds function as simple, dynamic systems through a series of hysteresis loops using measurements from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites. These loops illustrate the temporal relationship between runoff and terrestrial water storage in three regional-scale watersheds (> 150 000 km²) of the Columbia...

Key areas for conserving United States’ biodiversity likely threatened by future land use change

Creator:: Martinuzzi, S., Radeloff, V. C., Higgins, J. V., Helmers, D. P., Plantinga, A. J., and Lewis, D. J.
Abstract:: A major challenge for biodiversity conservation is to mitigate the effects of future environmental change, such as land use, in important areas for biodiversity conservation. In the United States, recent conservation efforts by The Nature Conservancy and partners have identified and mapped the nation's Areas of Biodiversity Significance (ABS), representing...

Isotopic constraints on the pre-industrial oceanic nitrogen budget

Creator:: Somes, C. J., Oschlies, A., and Schmittner, A.
Abstract:: The size of the bioavailable (i.e., “fixed”) nitrogen inventory in the ocean influences global marine productivity and the biological carbon pump. Despite its importance, the pre-industrial rates for the major source and sink terms of the oceanic fixed nitrogen budget, N₂ fixation and denitrification, respectively, are not well known. These...
