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'.
It's all relative: ranking the diversity of aquatic bacterial communities.
Diversity statistics can be used to detect differences in phylogenetic structure among microbial communities, and a subsampling analysis suggests that further sequencing from these particular clone libraries would not have substantially changed the richness rankings of the samples.
The minimum information about a genome sequence (MIGS) specification
Here, the minimum information about a genome sequence (MIGS) specification is introduced with the intent of promoting participation in its development and discussing the resources that will be required to develop improved mechanisms of metadata capture and exchange.
Rapid diversification of coevolving marine Synechococcus and a virus
The results indicate that rapid coevolution may contribute to the generation and maintenance of Synechococcus and virus diversity and thereby influence viral-mediated mortality of these key marine bacteria.
A comparison of taxon co-occurrence patterns for macro- and microorganisms.
It is shown that assemblages of microorganisms demonstrate nonrandom patterns of co-occurrence that are broadly similar to those found in assemblage of macroorganisms, suggesting that some taxon co- Occurrence patterns may be general characteristics of communities of organisms from all domains of life.
Antagonistic coevolution of marine planktonic viruses and their hosts.
The potential dynamics, underlying genetic mechanisms and fitness costs, and ecological impacts of virus-host coevolution in marine waters are considered and a variety of novel approaches for characterizing virus- host interactions offer new hope for a mechanistic understanding of antagonistic coev evolution in marine plankton.
Ecological perspectives on the sequenced genome collection
Our complete genome collection is one of our most valuable biological resources. A key challenge for the future is the interpretation of these genomes from an ecological perspective. In this review,
Alkenone producers inferred from well-preserved 18S rDNA in Greenland lake sediments
[1] The 18S ribosomal DNA (rDNA) sequences of haptophyte algae were successfully amplified using the polymerase chain reaction (PCR) from water filtrate, surface sediments, and a late-Holocene
Genomic diversification of marine cyanophages into stable ecotypes.
Isolates belonging to different subclusters were found to differ in genes that encoded auxiliary metabolic functions, restriction modification enzymes, and virion structural proteins, although the specific traits and selection pressures responsible for the maintenance of distinct ecotypes remain unknown.
Abundance of Broad Bacterial Taxa in the Sargasso Sea Explained by Environmental Conditions but Not Water Mass
The results suggest the potential for predicting the abundance of broad bacterioplankton groups throughout the Sargasso Sea using only a few environmental parameters.
