TL;DR: It is concluded that the EzTaxon-e database provides a useful taxonomic backbone for the identification of cultured and uncultured prokaryotes and offers a valuable means of communication among microbiologists who routinely encounter taxonomically novel isolates.

TL;DR: The overall distribution of ANI values generated by pairwise comparison of 6787 genomes of prokaryotes belonging to 22 phyla was investigated, finding an apparent distinction in the overall ANI distribution between intra- and interspecies relationships at around 95-96% ANI.

TL;DR: It is found that extreme acidic or alkaline pH conditions lead to assembly of phylogenetically more clustered bacterial communities through deterministic processes, whereas pH conditions close to neutral lead to phylogenetically less clustered bacteria communities with more stochasticity.

TL;DR: It is found that land use in itself has a weak but significant effect on the bacterial community composition, and variation in phylogenetic structure of dominant lineages is also significantly correlated with soil pH, confirming the importance of soil pH in structuring soil bacterial communities in Southeast Asia.

TL;DR: It is suggested that beyond the tree and vegetation line, the more extreme temperature fluctuations, stronger UV, lack of nutrients, and more frequent disturbance of the loose substrate of these slopes allows less competition and greater bacterial species diversity due to “lottery” recruitment, however, at the highest elevations, the physiological challenges are so extreme that fewer bacterial species are capable of surviving.
