  • Disturbances in a marine bacterioplankton system drive community assembly towards niche-based processes

    Creator:
    Vergin, Kevin L.
    Abstract:
    Over 100 monthly bacterioplankton DNA samples, from each of the surface and 200 m depths at the Bermuda Atlantic Time-series Study (BATS) site, were analyzed for community assembly processes. Correlation networks, filtered for potential autocorrelation artifacts, were constructed for each depth. Network characteristics for the two depths were remarkably similar...

    Wilhelm, Larry John
    Abstract:
    Candidatus Pelagibacter ubique is the first cultured representative of the SAR11 clade, a clade that is found throughout the oceans and accounts for approximately 25% of all bacterial cells [1]. It has a streamlined genome that is the smallest of any known free-living organism. In this study the complete genome...

  • An analysis of Sargasso Sea bacterioplankton diversity using 16S ribosomal RNA

    Creator:
    Britschgi, Theresa Baden
    Abstract:
    The objective of this project was to use ribosomal RNA genes, cloned from natural populations of Sargasso Sea bacterioplankton, as markers for picoplankton diversity. It is widely recognised that a majority of microorganisms have yet to be cultivated, and therefore much of extant microbial diversity remains unknown (50). The method...

  • Quantification of Osmolytes in the Sargasso Sea Surface Layer Water Column

    Creator:
    Muslin, Omran
    Abstract:
    Oceanic carbon cycling plays a major role in determining global atmospheric CO₂. A better understanding of dissolved organic matter and its constituents in the water column and how it affects marine carbon cycling is sought after. This study successfully measured osmolytes, low molecular zwitterionic compounds derived from amino acids, in...
