TL;DR: Spatial and temporal resource partitioning among Vibrionaceae strains coexisting in coastal bacterioplankton is described and environmental specialization may be an important correlate or even trigger of speciation among sympatric microbes.

TL;DR: It is shown that in two recently diverged populations of ocean bacteria, ecological differentiation has occurred akin to a sexual mechanism: A few genome regions have swept through subpopulations in a habitat-specific manner, accompanied by gradual separation of gene pools as evidenced by increased habitat specificity of the most recent recombinations.

TL;DR: This paper showed that in two recently diverged populations of ocean bacteria, ecological differentiation has occurred akin to a sexual mechanism: a few genome regions have swept through subpopulations in a habitat-specific manner, accompanied by gradual separation of gene pools as evidenced by increased habitat specificity of the most recent recombinations.

TL;DR: Although this test can not replace endoscopy and histological examination as diagnostic tools, classification based on microbial diversity is an effective complementary technique for IBD detection in pediatric patients.

TL;DR: It is suggested that ocean bacteria follow at least two different adaptive strategies, which constrain rates and bounds of evolutionary processes: the ‘opportuni-troph’, exploiting spatially and temporally variable resources and the passive oligotroph, efficiently using low nutrient concentrations.
