Safety factors for xylem failure by implosion and air-seeding within roots, trunks and branches of young and old conifer trees

Creator:: Domec, Jean-Christophe, Warren, Jeffrey M., Meinzer, Frederick C., and Lachenbruch, Barbara
Abstract:: The cohesion-tension theory of water transport states that hydrogen bonds hold water molecules together and that they are pulled through the xylem under tension. This tension could cause transport failure in at least two ways: collapse of the conduit walls (implosion), or rupture of the water column through air-seeding. The...

Creator:: Basta, Craig Thomas, Gupta, Rakesh, Leichti, Robert J., and Sinha, Arijit
Abstract:: Current compression perpendicular-to-grain (C⊥) design values for wood members are based on mean stress obtained from ASTM D143 specimen. The standard ASTM test with metal on wood bearing has limited applicability in modern construction assemblies with C⊥ loading scenarios. Previous work has shown that end-bearing conditions and wood-on-wood C⊥ bearing...

Comparing streambed light availability and canopy cover in streams with old-growth versus early-mature riparian forests in western Oregon

Creator:: Warren, Dana R., Keeton, William S., Bechtold, Heather A., and Rosi-Marshall, Emma J.
Abstract:: Light availability strongly influences stream primary production, water temperatures and resource availability at the base of stream food webs. In headwater streams, light is regulated primarily by the riparian forest, but few studies have evaluated the influence of riparian forest stand age and associated structural differences on light availability.

Abstract:: Information on land cover at global and continental scales is critical for addressing a range of ecological, socioeconomic and policy questions. Global land cover maps have evolved rapidly in the last decade, but efforts to evaluate map uncertainties have been limited, especially in remote areas like Northern Eurasia. Northern Eurasia...

Upper ocean thermohaline fields near 2°S, 156°E, during the Tropical Ocean-Global Atmosphere - Coupled Ocean-Atmosphere Response Experiment, November 1992 to February 1993

Creator:: Huyer, Adriana, 1945-, Kosro, P. Michael, 1951-, Lukas, Roger, and Hacker, Peter
Abstract:: Zonal and meridional Seasoar sections centered at 1°50’S, 156°06’E were repeated >30 times in three 20-day periods between November 13, 1992, and February 15, 1993. Both sections were 130 km long, and sampling depth was 0–280 m, with a vertical resolution of ~2 dbar (2 x 104 Pa) and a...

Carbon accumulation of tropical peatlands over millennia: a modeling approach

Creator:: Kurnianto, Sofyan, Warren, Matthew, Talbot, Julie, Kauffman, Boone, Murdiyarso, Daniel, and Frolking, Steve
Abstract:: Tropical peatlands cover an estimated 440,000 km² (~10% of global peatland area) and are significant in the global carbon cycle by storing about 40–90 Gt C in peat. Over the past several decades, tropical peatlands have experienced high rates of deforestation and conversion, which is often associated with lowering the...

The Type II Secretion Pathway in Vibrio cholerae Is Characterized by Growth Phase-Dependent Expression of Exoprotein Genes and Is Positively Regulated by σ[superscript E]

Creator:: Zielke, Ryszard A., Simmons, Ryan S., Park, Bo R., Nonogaki, Mariko, Emerson, Sarah, and Sikora, Aleksandra E.
Abstract:: Vibrio cholerae, an etiological agent of cholera, circulates between aquatic reservoirs and the human gastrointestinal tract. The type II secretion (T2S) system plays a pivotal role in both stages of the lifestyle by exporting multiple proteins, including cholera toxin. Here, we studied the kinetics of expression of genes encoding the...

Catalyst selective and regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates: synthetic and computational studies

Creator:: Gould, Eoin, Walden, Daniel M., Kasten, Kevin, Johnston, Ryne C., Wu, Jiufeng, Slawin, Alexandra M., Mustard, Thomas J. L., Johnston, Brittany, Davies, Tony, Cheong, Paul Ha-Yeon, and Smith, Andrew D.
Abstract:: The regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates is described, with DMAP giving preferential N-carboxylation and triazolinylidenes promoting selective C-carboxylation (both with up to >99 : 1 regioselectivity). An enantioselective O- to C-carboxyl variant using NHC catalysis is demonstrated (up to 92% ee), while mechanistic and DFT studies outline...

Development of C₁₃-norisoprenoids, carotenoids and other volatile compounds in Vitis vinifera L. Cv. Pinot noir grapes

Creator:: Yuan, Fang and Qian, Michael C.
Abstract:: Developmental changes in the carotenoids and volatile compounds of Pinot noir grape berries were investigated in this study from pea size to harvest during 2012. HPLC analysis showed continued decrease of lutein, β-carotene, neochrome a and neoxanthin continued to decrease during berry development, with rapid decrease of lutein and (9′z)-neoxanthin...

Forest disturbance across the conterminous United States from 1985-2012: The emerging dominance of forest decline

Creator:: Cohen, Warren B., Yang, Zhiqiang, Stehman, Stephen V., Schroeder, Todd A., Bell, David M., Masek, Jeffrey G., Huang, Chengquan, and Meigs, Garrett W.
Abstract:: Evidence of shifting dominance among major forest disturbance agent classes regionally to globally has been emerging in the literature. For example, climate-related stress and secondary stressors on forests (e.g., insect and disease, fire) have dramatically increased since the turn of the century globally, while harvest rates in the western US...

Photosynthetic fractionation of ¹³C and concentrations of dissolved CO₂ in the central equatorial Pacific during the last 255,000 years

Creator:: Jasper, John P, Hayes, J. M., Mix, Alan C., and Prahl, Fredrick
Abstract:: Carbon isotopically based estimates of CO₂ levels have been generated from a record of the photosynthetic fractionation of ¹³C (≡εp) in a central equatorial Pacific sediment core that spans the last ~255 ka. Contents of ¹³C in phytoplanktonic biomass were determined by analysis of C37 alkadienones. These compounds are exclusive...

Creator:: Schmittner, A., Gruber, N., Mix, A. C., Key, R. M., Tagliabue, A., and Westberry, T. K.
Abstract:: Analysis of observations and sensitivity experiments with a new three-dimensional global model of stable carbon isotope cycling elucidate processes that control the distribution of delta C-13 of dissolved inorganic carbon (DIC) in the contemporary and preindustrial ocean. Biological fractionation and the sinking of isotopically light delta C-13 organic matter from...

Millennial–scale CaCO₃ and C[subscript ORG] events along the northern and central California margins : stratigraphy and origins

Creator:: Lyle, Mitchell, Mix, Alan C., Ravelo, A. Christina, Andreasen, Dyke, Heusser, Linda, and Olivarez, Annette
Abstract:: Sediments from five Leg 167 drill sites and three piston cores were analyzed for C[subscript ORG] and CaCO₃. Oxygen isotope stratigraphy on benthic foraminifers was used to assign age models to these sedimentary records. We find that the northern and central California margin is characterized by k.y.-scale events that can...

Abstract:: To test the hypothesis that embryogenesis depends upon α-tocopherol (E) to protect embryo polyunsaturated fatty acids (PUFAs) from lipid peroxidation, new methodologies were applied to measure α-tocopherol and fatty acids in extracts from saponified zebrafish embryos. A solid phase extraction method was developed to separate the analyte classes, using a...
