Gases in ice cores

Creator:: Bender, Michael, Sowers, Todd, and Brook, Edward J.
Abstract:: Air trapped in glacial ice offers a means of reconstructing variations in the concentrations of atmospheric gases over time scales ranging from anthropogenic (last 200 yr) to glacial/interglacial (hundreds of thousands of years). In this paper, we review the glaciological processes by which air is trapped in the ice and...

Chronology reconstruction for the disturbed bottom section of the GISP2 and the GRIP ice cores: Implications for Termination II in Greenland

Creator:: Suwa, Makoto, von Fischer, Joseph C., Bender, Michael L., Landais, Amaelle, and Brook, Edward J.
Abstract:: We have reconstructed chronology for the disturbed bottom parts of the GRIP and GISP2 ice cores using the combined paleoatmospheric records of CH₄ concentration and δ¹⁸O[subscript atm] in the trapped gases. Our reconstructed ages for basal ice samples are based on comparison of published measurements of CH₄ and δ¹⁸O[subscript atm]...

From Pepper to the Philippines: American Experiences in Southeast Asia, 1784 - 1898

Creator:: Baer, Adela S., 1931-
Abstract:: Since Americans were a minority among the outsiders in Southeast Asia before the twentieth century, a legitimate question is: Why write about them there? There are three sides to the answer. For one, there has been no general account of Americans in nineteenth-century Southeast Asia.¹ In addition, the mistakes of...

Effects of Cu/Zn Superoxide Dismutase (sod1) Genotype and Genetic Background on Growth, Reproduction and Defense in Biomphalaria glabrata

Creator:: Bonner, Kaitlin M., Bayne, Christopher J., Larson, Maureen K., and Blouin, Michael S.
Abstract:: Resistance of the snail Biomphalaria glabrata to the trematode Schistosoma mansoni is correlated with allelic variation at copper-zinc superoxide dismutase (sod1). We tested whether there is a fitness cost associated with carrying the most resistant allele in three outbred laboratory populations of snails. These three populations were derived from the...

Global net community production and the putative net heterotrophy of the oligotrophic oceans

Creator:: Westberry, Toby K., Williams, Peter J. le B., and Behrenfeld, Michael J.
Abstract:: Reconciling rates of organic carbon export from the euphotic zone with the consumption of organic material in the dark ocean remains one of the major quantitative uncertainties of the ocean carbon cycle. Euphotic zone net community production (NCP) provides one broad constraint on export flux and potential carbon drawdown. However,...

Powder Injection Molding of Ceria-Stabilized, Zirconia-Toughened Mullite Parts for UAV Engine Components

Creator:: Martin, Renee, Vick, Michael, Enneti, Ravi K., and Atre, Sundar V.
Abstract:: Powder injection molding (PIM) of ceria-stabilized, zirconia-toughened mullite composites were investigated in the present article with the goal of obtaining performance enhancement in complex geometries for energy and transportation applications. A powder-polymer mixture (feedstock) was developed and characterized to determine its suitability for fabricating complex components using the PIM process....

Hyperdiverse Gene Cluster in Snail Host Conveys Resistance to Human Schistosome Parasites

Creator:: Tennessen, Jacob A., Théron, André, Marine, Melanie, Yeh, Jan-Ying, Rognon, Anne, and Blouin, Michael S.
Abstract:: Schistosomiasis, a neglected global pandemic, may be curtailed by blocking transmission of the parasite via its intermediate hosts, aquatic snails. Elucidating the genetic basis of snail-schistosome interaction is a key to this strategy. Here we map a natural parasite-resistance polymorphism from a Caribbean population of the snail Biomphalaria glabrata. In...

Genome-Wide Scan and Test of Candidate Genes in the Snail Biomphalaria glabrata Reveal New Locus Influencing Resistance to Schistosoma mansoni

Creator:: Tennessen, Jacob A., Bonner, Kaitlin M., Bollmann, Stephanie R., Johnstun, Joel A., Yeh, Jan-Ying, Marine, Melanie, Tavalire, Hannah F., Bayne, Christopher J., and Blouin, Michael S.
Abstract:: Background: New strategies to combat the global scourge of schistosomiasis may be revealed by increased understanding of the mechanisms by which the obligate snail host can resist the schistosome parasite. However, few molecular markers linked to resistance have been identified and characterized in snails. Methodology/Principal Findings: Here we test six...

Dynamic DNA cytosine methylation in the Populus trichocarpa genome: tissue-level variation and relationship to gene expression

Creator:: Vining, Kelly J., Pomraning, Kyle R., Wilhelm, Larry J., Priest, Henry D., Pellegrini, Matteo, Mockler, Todd C., Freitag, Michael, and Strauss, Steven H.
Abstract:: Background: DNA cytosine methylation is an epigenetic modification that has been implicated in many biological processes. However, large-scale epigenomic studies have been applied to very few plant species, and variability in methylation among specialized tissues and its relationship to gene expression is poorly understood. Results: We surveyed DNA methylation from...

Methylome reorganization during in vitro dedifferentiation and regeneration of Populus trichocarpa

Creator:: Vining, Kelly, Pomraning, Kyle R., Wilhelm, Larry J., Ma, Cathleen, Pellegrini, Matteo, Di, Yanming, Mockler, Todd C., Freitag, Michael, and Strauss, Steven H.
Abstract:: Background: Cytosine DNA methylation (5mC) is an epigenetic modification that is important to genome stability and regulation of gene expression. Perturbations of 5mC have been implicated as a cause of phenotypic variation among plants regenerated through in vitro culture systems. However, the pattern of change in 5mC and its functional...
