The paper uses metagenomics to compare microbial communities in coastal and inland hypersaline lakes, finding higher connectivity and allopatric speciation in coastal systems.

The paper shows SAR11 bacteria use promiscuous recombination to form sequence-discrete species with lower ANI thresholds than other microbes.

The paper identifies ecological cohesiveness and homologous recombination as mechanisms maintaining microbial species and genomovars in two bacterial species.

The paper identifies a 99.5% ANI gap in bacteriophage genomes that can define intra-species units, proposing 'genomovars' as a standardized classification.
