Microbial biogeography: putting microorganisms on the map
Current evidence confirms that, as proposed by the Baas-Becking hypothesis, 'the environment selects' and is, in part, responsible for spatial variation in microbial diversity, but recent studies also dispute the idea that 'everything is everywhere'. Expand
Use of SYBR Green I for rapid epifluorescence counts of marine viruses and bacteria
A new nucleic acid stain, SYBR Green I, can be used for the rapid and accurate determination of viral and bacterial abundances in diverse marine samples and may facilitate incorporation of viral research into most aquatic microbiology laboratories. Expand
Marine viruses and their biogeochemical and ecological effects
Newly developed fluorescence and molecular techniques leave the field poised to make significant advances towards evaluating and quantifying viruses' effects on biogeochemical and ecological processes. Expand
Thymidine incorporation as a measure of heterotrophic bacterioplankton production in marine surface waters: Evaluation and field results
To assess bacterioplankton production in the sea, we have developed a procedure for measuring growth based on incorporation of tritiated thymidine into DNA; the accuracy of this procedure was testedExpand
Relationships between Biovolume and Biomass of Naturally Derived Marine Bacterioplankton
It is concluded that natural marine bacterial biomass and production may be higher than was previously thought and that variations in bacterial size may not reflect variations in biomass per cell. Expand

In all three regions studied, it appeared that a significant fraction of the total primary production was utilized by the bacterioplankton and that substantial growth could occur in the absence of large particles. Expand
Beyond biogeographic patterns: processes shaping the microbial landscape
It is proposed that four processes — selection, drift, dispersal and mutation — create and maintain microbial biogeographic patterns on inseparable ecological and evolutionary scales. Expand

Data on the structures of these communities show that they adhere to universal biological rules, helping to anticipate how microbial communities and their activities will shift in a changing world. Expand
Significance of Size and Nucleic Acid Content Heterogeneity as Measured by Flow Cytometry in Natural Planktonic Bacteria
In various experiments where predator pressure on bacteria had been reduced, the percentage contribution of HDNA bacteria to total bacterial numbers (%HDNA) increased, such that theHDNA bacteria are the dynamic members of the bacterial assemblage. Expand
Every base matters: assessing small subunit rRNA primers for marine microbiomes with mock communities, time series and global field samples.
It is shown that beyond in silico predictions, testing with mock communities and field samples is important in primer selection, and a single mismatch can strongly bias amplification, but even perfectly matched primers can exhibit preferential amplification. Expand
