    Examining mesozooplankton patch structure and its implications for trophic interactions in the northern Gulf of Mexico (2016)
    Oxford University Press
    Details
    Publication Date: 2016-08-20
    Description: Plankton patch dynamics strongly influences rates of trophic transfer and many ecological processes, yet patchiness is poorly described, especially on fine-scales (cm to 10s of m). We deployed the In Situ Ichthyoplankton Imaging System beneath the Mississippi River plume to measure horizontal distributions of zooplankton across three depth zones (10, 25 and 35 m). We found that larval fishes were significantly aggregated in the shallow (10 m) and deep (35 m) waters, but were randomly distributed at 25 m. In contrast, gelatinous organisms were typically randomly distributed, but shrimps and chaetognaths showed a strong degree of aggregation on fine-scales at all depths. One deep-water transect (35 m) was marked by a ~1.5-km zone of hypoxia (O 2  〈 2.0 mg L –1 ) that contained no larval fishes and few zooplankton that were otherwise abundant throughout the sampling area. The exceptions to this trend were the shrimps and cumaceans, which aggregated within the hypoxic zone, suggesting they were able to tolerate those conditions. Correlation analyses of zooplankton showed differing relationships of zooplankton abundance to physical variables among sampling depths; however, zooplankton were consistently positively correlated with one another, indicating the presence of taxonomically heterogeneous patches.

    Primary carbonatite melt from deeply subducted oceanic crust (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-08-01
    Description: Partial melting in the Earth's mantle plays an important part in generating the geochemical and isotopic diversity observed in volcanic rocks at the surface. Identifying the composition of these primary melts in the mantle is crucial for establishing links between mantle geochemical 'reservoirs' and fundamental geodynamic processes. Mineral inclusions in natural diamonds have provided a unique window into such deep mantle processes. Here we provide experimental and geochemical evidence that silicate mineral inclusions in diamonds from Juina, Brazil, crystallized from primary and evolved carbonatite melts in the mantle transition zone and deep upper mantle. The incompatible trace element abundances calculated for a melt coexisting with a calcium-titanium-silicate perovskite inclusion indicate deep melting of carbonated oceanic crust, probably at transition-zone depths. Further to perovskite, calcic-majorite garnet inclusions record crystallization in the deep upper mantle from an evolved melt that closely resembles estimates of primitive carbonatite on the basis of volcanic rocks. Small-degree melts of subducted crust can be viewed as agents of chemical mass-transfer in the upper mantle and transition zone, leaving a chemical imprint of ocean crust that can possibly endure for billions of years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walter, M J -- Bulanova, G P -- Armstrong, L S -- Keshav, S -- Blundy, J D -- Gudfinnsson, G -- Lord, O T -- Lennie, A R -- Clark, S M -- Smith, C B -- Gobbo, L -- England -- Nature. 2008 Jul 31;454(7204):622-5. doi: 10.1038/nature07132.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, University of Bristol, Queen's Road, Bristol BS8 1RJ, UK. m.j.walter@bris.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18668105" target="_blank"〉PubMed〈/a〉

    Antigenic and genetic characteristics of swine-origin 2009 A(H1N1) influenza viruses circulating in humans (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-05-26
    Description: Since its identification in April 2009, an A(H1N1) virus containing a unique combination of gene segments from both North American and Eurasian swine lineages has continued to circulate in humans. The lack of similarity between the 2009 A(H1N1) virus and its nearest relatives indicates that its gene segments have been circulating undetected for an extended period. Its low genetic diversity suggests that the introduction into humans was a single event or multiple events of similar viruses. Molecular markers predictive of adaptation to humans are not currently present in 2009 A(H1N1) viruses, suggesting that previously unrecognized molecular determinants could be responsible for the transmission among humans. Antigenically the viruses are homogeneous and similar to North American swine A(H1N1) viruses but distinct from seasonal human A(H1N1).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3250984/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3250984/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garten, Rebecca J -- Davis, C Todd -- Russell, Colin A -- Shu, Bo -- Lindstrom, Stephen -- Balish, Amanda -- Sessions, Wendy M -- Xu, Xiyan -- Skepner, Eugene -- Deyde, Varough -- Okomo-Adhiambo, Margaret -- Gubareva, Larisa -- Barnes, John -- Smith, Catherine B -- Emery, Shannon L -- Hillman, Michael J -- Rivailler, Pierre -- Smagala, James -- de Graaf, Miranda -- Burke, David F -- Fouchier, Ron A M -- Pappas, Claudia -- Alpuche-Aranda, Celia M -- Lopez-Gatell, Hugo -- Olivera, Hiram -- Lopez, Irma -- Myers, Christopher A -- Faix, Dennis -- Blair, Patrick J -- Yu, Cindy -- Keene, Kimberly M -- Dotson, P David Jr -- Boxrud, David -- Sambol, Anthony R -- Abid, Syed H -- St George, Kirsten -- Bannerman, Tammy -- Moore, Amanda L -- Stringer, David J -- Blevins, Patricia -- Demmler-Harrison, Gail J -- Ginsberg, Michele -- Kriner, Paula -- Waterman, Steve -- Smole, Sandra -- Guevara, Hugo F -- Belongia, Edward A -- Clark, Patricia A -- Beatrice, Sara T -- Donis, Ruben -- Katz, Jacqueline -- Finelli, Lyn -- Bridges, Carolyn B -- Shaw, Michael -- Jernigan, Daniel B -- Uyeki, Timothy M -- Smith, Derek J -- Klimov, Alexander I -- Cox, Nancy J -- DP1 OD000490-01/OD/NIH HHS/ -- DP1-OD000490-01/OD/NIH HHS/ -- HHSN266200700010C/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):197-201. doi: 10.1126/science.1176225.

    Deep mantle cycling of oceanic crust: evidence from diamonds and their mineral inclusions (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-09-17
    Description: A primary consequence of plate tectonics is that basaltic oceanic crust subducts with lithospheric slabs into the mantle. Seismological studies extend this process to the lower mantle, and geochemical observations indicate return of oceanic crust to the upper mantle in plumes. There has been no direct petrologic evidence, however, of the return of subducted oceanic crustal components from the lower mantle. We analyzed superdeep diamonds from Juina-5 kimberlite, Brazil, which host inclusions with compositions comprising the entire phase assemblage expected to crystallize from basalt under lower-mantle conditions. The inclusion mineralogies require exhumation from the lower to upper mantle. Because the diamond hosts have carbon isotope signatures consistent with surface-derived carbon, we conclude that the deep carbon cycle extends into the lower mantle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walter, M J -- Kohn, S C -- Araujo, D -- Bulanova, G P -- Smith, C B -- Gaillou, E -- Wang, J -- Steele, A -- Shirey, S B -- New York, N.Y. -- Science. 2011 Oct 7;334(6052):54-7. doi: 10.1126/science.1209300.

    Presynaptic alpha-receptor subsensitivity after long-term antidepressant treatment (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-10-20
    Description: After 3 weeks of twice-daily administration of desipramine to rats, the frequency-response curve for field stimulation of adrenergic neurons in isolated left atrial strips was shifted markedly to the left and the efflux of [3H]norepinephrine was enhanced greatly. After 1 day of treatment, only slight shifts in the frequency-response curve and small increases in [3H]norepinephrine efflux occurred although inhibition of [3H]norepinephrine uptake was already maximal, and phenoxybenzamine caused a further shift to the left in the frequency-response curve similar to that which occurred after 3 weeks of desipramine treatment alone. A gradual decrease in the sensitivity of the presynaptic alpha receptor would explain the delay in the onset of the linical effect of the tricyclic antidepressants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crews, F T -- Smith, C B -- New York, N.Y. -- Science. 1978 Oct 20;202(4365):322-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/211589" target="_blank"〉PubMed〈/a〉

    Metabolic mapping of functional activity in the hypothalamo-neurohypophysial system of the rat (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-17
    Description: Physiological stimulation of the hypothalamo-neurohypophysial system by salt loading of rats resulted in a dramatically increased glucose utilization in the posterior pituitary but not in the paraventricular or supraoptic nuclei. The good correlation between glucose utilization and neural activity in the posterior pituitary (that is, nerve terminals) contrasted with the lack of correlation in the paraventricular and supraoptic nuclei (that is, the sites of the cell bodies of the same neurons). This difference in the metabolic response to functional activity between the two regions of these neurons can be explained by the differences in surface-to-volume ratios of these regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schwartz, W J -- Smith, C B -- Davidsen, L -- Savaki, H -- Sokoloff, L -- Mata, M -- Fink, D J -- Gainer, H -- New York, N.Y. -- Science. 1979 Aug 17;205(4407):723-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/462184" target="_blank"〉PubMed〈/a〉
