What are bacterial species?
  • F. Cohan
  • Biology, Environmental Science
    Annual review of microbiology
  • 2002
TLDR
These molecular methods suggest that a typical named species contains many ecotypes, each with the universal attributes of species, which is more like a genus than a species.

Re-evaluating prokaryotic species
TLDR
The current and future impact of multilocus nucleotide-sequence-based approaches to prokaryotic systematics are discussed and the potential, and difficulties, of assigning species status to biologically or ecologically meaningful sequence clusters are considered.

Bacterial species and speciation.
  • F. Cohan
  • Biology
    Systematic biology
  • 1 August 2001
TLDR
Owing to the rarity and promiscuity of bacterial genetic exchange, speciation in the bacterial world is expected to be much less constrained than in the world of animals and plants.

Discovery and classification of ecological diversity in the bacterial world: the role of DNA sequence data.
TLDR
Sequence similarity clustering in protein-coding genes is recommended as a primary criterion for demarcating taxa and can be expected to disclose many previously unknown ecological populations of bacteria.

Population level functional diversity in a microbial community revealed by comparative genomic and metagenomic analyses
TLDR
Genomic information from these mat-specific isolates and metagenomic information can be coupled to detect naturally occurring populations that are associated with different functionalities, not always represented by isolates, but which may nevertheless be important for niche partitioning and the establishment of microbial community structure.

Origins of bacterial diversity through horizontal genetic transfer and adaptation to new ecological niches.
TLDR
The features of bacterial genetics that allow HGT, the similarities between organisms that foster HGT between them, the limits to the kinds of adaptations that can be transferred, and amelioration of fitness costs associated with HGT are reviewed.

Identifying the fundamental units of bacterial diversity: A paradigm shift to incorporate ecology into bacterial systematics
TLDR
This work introduces a sequence-based approach (“ecotype simulation”) to model the evolutionary dynamics of bacterial populations and to identify ecotypes within a natural community, focusing here on two Bacillus clades surveyed from the “Evolution Canyons” of Israel.

Opinion: Re-evaluating prokaryotic species.
TLDR
The current and future impact of multilocus nucleotide-sequence-based approaches to prokaryotic systematics are discussed and the potential, and difficulties, of assigning species status to biologically or ecologically meaningful sequence clusters are considered.

A Systematics for Discovering the Fundamental Units of Bacterial Diversity
View on Elsevier
Bacillus mojavensis sp. nov., distinguishable from Bacillus subtilis by sexual isolation, divergence in DNA sequence, and differences in fatty acid composition.
A number of Bacillus strains isolated from desert soil samples were shown to belong to a previously unidentified species, for which we propose the name Bacillus mojavensis. The type strain is RO-H-1…
