Comprehensive multiyear carbon budget of a temperate headwater stream

Creator:: Argerich, Alba, Haggerty, Roy, Johnson, Sherri L., Wondzell, Steven M., Dosch, Nicholas, Corson-Rikert, Hayley, Ashkenas, Linda R., Pennington, Robert, and Thomas, Christoph K.
Abstract:: Headwater streams comprise nearly 90% of the total length of perennial channels in global catchments. They mineralize organic carbon entering from terrestrial systems, evade terrestrial carbon dioxide (CO₂ ), and generate and remove carbon through in-stream primary production and respiration. Despite their importance, headwater streams are often neglected in global...

A dynamic leaf gas-exchange strategy is conserved in woody plants under changing ambient CO₂: evidence from carbon isotope discrimination in paleo and CO₂ enrichment studies

Creator:: Voelker, Steven L., Brooks, J. Renée, Meinzer, Frederick C., Anderson, Rebecca, Bader, Martin K.-F., Battipaglia, Giovanna, Becklin, Katie M., Beerling, David, Bert, Didier, Betancourt, Julio L., Dawson, Todd E., Domec, Jean-Christophe, Guyette, Richard P., Körner, Christian, Leavitt, Steven W., Linder, Sune, Marshall, John D., Mildner, Manuel, Ogée, Jérôme, Panyushkina, Irina, Plumpton, Heather J., Pregitzer, Kurt S., Saurer, Matthias, Smith, Andrew R., Siegwolf, Rolf T. W., Stambaugh, Michael C., Talhelm, Alan F., Tardif, Jacques C., Van de Water, Peter K., Ward, Joy K., and Wingate, Lisa
Abstract:: Rising atmospheric [CO₂], cₐ, is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO₂],...

Relationship Between Wildfire, Salvage Logging, and Occupancy of Nesting Territories by Northern Spotted Owls

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate the short-term...

Gleaning Unexpected Fruits from Hard-Won Synthetases: Probing Principles of Permissivity in Non-canonical Amino Acid–tRNA Synthetases

Creator:: Cooley, Richard B., Karplus, P. Andrew, and Mehl, Ryan A.
Abstract:: The site-specific incorporation of non-canonical amino acids (ncAAs) into proteins is an important tool for understanding biological function. Traditionally, each new ncAA targeted requires a resource-consuming process of generating new ncAA aminoacyl tRNA synthetase/tRNACUA pairs. However, the discovery that some tRNA synthetases are “permissive,” in that they can incorporate multiple...

Structures of Arg- and Gln-type bacterial Cysteine Dioxygenase Homologs

Creator:: Driggers, Camden M., Hartman, Steven J., and Karplus, P. Andrew
Abstract:: In some bacteria, cysteine is converted to cysteine sulfinic acid by cysteine dioxygenases (CDO) that are only ∼15–30% identical in sequence to mammalian CDOs. Among bacterial proteins having this range of sequence similarity to mammalian CDO are some that conserve an active site Arg residue (“Arg-type” enzymes) and some having...

Conformation-dependent backbone geometry restraints set a new standard for protein crystallographic refinement

Creator:: Moriarty, Nigel W., Tronrud, Dale E., Adams, Paul D., and Karplus, P. Andrew
Abstract:: Ideal values of bond angles and lengths used as external restraints are crucial for the successful refinement of protein crystal structures at all but the highest of resolutions. The restraints in common usage today have been designed based on the assumption that each type of bond or angle has a...

Precipitation-snowmelt timing and snowmelt augmentation of large peak flow events, western Cascades, Oregon

Creator:: Jennings, Keith and Jones, Julia A.
Abstract:: This study tested multiple hydrologic mechanisms to explain snowpack dynamics in extreme rain-on-snow floods, which occur widely in the temperate and polar regions. We examined 26, 10 day large storm events over the period 1992–2012 in the H.J. Andrews Experimental Forest in western Oregon, using statistical analyses (regression, ANOVA, and...

A large proportion of North American net ecosystem production is offset by emissions from harvested products, river/stream evasion, and biomass burning

Creator:: Turner, David P., Jacobson, Andrew R., Ritts, William D., Wang, Weile L., and Nemani, Ramakrishna
Abstract:: Diagnostic carbon cycle models produce estimates of net ecosystem production (NEP, the balance of net primary production and heterotrophic respiration) by integrating information from (i) satellite-based observations of land surface vegetation characteristics; (ii) distributed meteorological data; and (iii) eddy covariance flux tower observations of net ecosystem exchange (NEE) (used in...

The effect of El Niño Southern Oscillation cycles on the decadal scale suspended sediment behavior of a coastal dry-summer subtropical catchment

Creator:: Gray, Andrew B., Pasternack, Gregory B., Watson, Elizabeth B., Warrick, Jonathan A., and Goñi, Miguel A.
Abstract:: Rivers display temporal dependence in suspended sediment–water discharge relationships. Although most work has focused on multi-decadal trends, river sediment behavior often displays sub-decadal scale fluctuations that have received little attention. The objectives of this study were to identify inter-annual to decadal scale fluctuations in the suspended sediment–discharge relationship of a...
