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...
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...
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...
Diatoms are a ubiquitous group of plankton responsible for 20-40% of oceanic
primary production, and a higher fraction of organic matter export to the ocean
interior. Diatoms actively transport dissolved inorganic silicon into their cells, and
through the process of silicification (i.e. biogenic silica production) they build tough
and intricate...
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...
Caribbean women authors, in an attempt to reclaim their voices lost to patriarchy and colonialism, are creating a new literary tradition by expanding the boundaries of the Bildungsroman genre. Many have challenged the conservative male Bildungsroman's deeply entrenched gender bias where female transcendence was impossible due to cultural prescriptions that...
