NooneDCEOASArcticCycloneWaterSupportingInformation.pdf

Creator:: Klein, Eric S., Cherry, J. E., Young, J., Noone, D., Leffler, A. J., and Welker, J. M.
Abstract:: Rapid Arctic warming is associated with important water cycle changes: sea ice loss, increasing atmospheric humidity, permafrost thaw, and water-induced ecosystem changes. Understanding these complex modern processes is critical to interpreting past hydrologic changes preserved in paleoclimate records and predicting future Arctic changes. Cyclones are a prevalent Arctic feature and...

Advancing interpretations of ¹⁴C-uptake measurements in the context of phytoplankton physiology and ecology

Creator:: Milligan, Allen J., Halsey, Kimberly H., and Behrenfeld, Michael J.
Abstract:: The ¹⁴C-uptake method is the most common approach employed for estimating primary production in the ocean. Normalizing ¹⁴C-uptake to chlorophyll a and time yields a value termed the assimilation number, which is thought to reflect phytoplankton physiology. It is often assumed that the measured rate of ¹⁴C-uptake is between net...

Eutrophication weakens stabilizing effects of diversity in natural grasslands

Creator:: Hautier, Yann, Seabloom, Eric W., Borer, Elizabeth T., Adler, Peter B., Harpole, W. Stanley, Hillebrand, Helmut, Lind, Eric M., MacDougall, Andrew S., Stevens, Carly J., Bakker, Jonathan D., Buckley, Yvonne M., Chu, Chengjin, Collins, Scott L., Daleo, Pedro, Damschen, Ellen I., Davies, Kendi F., Fay, Philip A., Firn, Jennifer, Gruner, Daniel S., Jin, Virginia L., Klein, Julia A., Knops, Johannes M. H., La Pierre, Kimberly J., Li, Wei, McCulley, Rebecca L., Melbourne, Brett A., Moore, Joslin L., O'Halloran, Lydia R., Prober, Suzanne M., Risch, Anita C., Sankaran, Mahesh, Schuetz, Martin, and Hector, Andy
Abstract:: Studies of experimental grassland communities¹⁻⁷ have demonstrated that plant diversity can stabilize productivity through species asynchrony, in which decreases in the biomass of some species are compensated for by increases in others[superscript 1,2]. However, it remains unknown whether these findings are relevant to natural ecosystems, especially those for which species...

Pelagibacter metabolism of diatom-derived volatile organic compounds imposes an energetic tax on photosynthetic carbon fixation

Creator:: Thompson, Douglas A., Moore, Eric R., Davie-Martin, Cleo L., Giovannani, Stephen J., and Halsey, Kimberly, H.
Abstract:: Photosynthetic diatoms and marine bacteria contribute about one third of the net primary production in marine environments. Understanding the interactions between these two organisms is potentially important to the over all flow of carbon in the marine ecosystem.

Peroxiredoxins: Guardians Against Oxidative Stress and Modulators of Peroxide Signaling

Creator:: Perkins, Arden, Nelson, Kimberly J., Parsonage, Derek, Poole, Leslie B., and Karplus, P. Andrew
Abstract:: Peroxiredoxins (Prxs) are a ubiquitous family of cysteine-dependent peroxidase enzymes that play dominant roles in regulating peroxide levels within cells. These enzymes, often present at high levels and capable of rapidly clearing peroxides, display a remarkable array of variations in their oligomeric states and susceptibility to regulation by hyperoxidative inactivation...

Cesium radioisotope content of wild edible fungi, mineral soil, and surface litter in western North America after the Fukushima nuclear accident

Creator:: Trappe, Matthew J., Minc, Leah D., Kittredge, Kimberly S., and Pink, Jeremias W.
Abstract:: We measured activity levels of cesium radioisotopes ¹³⁴Cs and ¹³⁷Cs in wild edible fungi, mineral soil, and surface litter of the west coast of North America from southern California to northern Vancouver Island after the Fukushima nuclear accident. All activity measurements were below governmental limits for human health. ¹³⁷Cs activity...

Evaluating peroxiredoxin sensitivity towards inactivation by peroxide substrates

Creator:: Nelson, Kimberly J., Parsonage, Derek, Karplus, P. Andrew, and Poole, Leslie B.
Abstract:: Peroxiredoxins (Prxs) are very effective peroxide reducing enzymes, but also are susceptible to being oxidatively inactivated by their own substrates. The level of sensitivity to such hyperoxidation varies depending both on the enzyme involved and the type of peroxide substrate. For some Prxs, the hyperoxidation has physiological relevance, so it...

OMalleyFigure5.tif

Creator:: O'Malley, Robert T., Behrenfeld, Michael J., Westberry, Toby K., Milligan, Allen J., Reese, Douglas C., and Halsey, Kimberly H.
Abstract:: Submarine volcanic eruptions can result in both real and apparent changes in marine algal communities, e.g., increases in phytoplankton biomass and/or growth rates that can cover thousands of square kilometers. Satellite ocean color monitoring detects these changes as increases in chlorophyll and particulate backscattering. Detailed, high resolution analysis is needed...
