Current biology : CB, 22(11), R451–3. doi:10.1016/j.cub.2012.04.034 Two processes suggested to drive bacterial speciation – periodic selection and recombination – are generally thought to be mutually opposed. Recent work shows that data taken as evidence supporting the former may be…

Vos, M. (2011). A species concept for bacteria based on adaptive divergence. Trends in microbiology, 19(1), 1–7. doi:10.1016/j.tim.2010.10.003 Bacterial strains are currently grouped into species based on overall genomic similarity and sharing of phenotypes deemed ecologically important. Many believe this polyphasic taxonomy is in need of revision because it lacks grounding in evolutionary theory, and…

http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.0050077 Abstract: The world’s oceans contain a complex mixture of micro-organisms that are for the most part, uncharacterized both genetically and biochemically. We report here a metagenomic study of the marine planktonic microbiota in which surface (mostly marine) water samples were analyzed as part of the Sorcerer II Global Ocean Sampling expedition. These samples, collected…
