Horizontal gene transfer (HGT) is arguably the most conspicuous feature of bacterial
evolution. Evidence for HGT is found in most bacterial genomes. Although HGT can …

The primary habitat of Escherichia coli is the vertebrate gut, where it is the predominant
aerobic organism, living in symbiosis with its host. Despite the occurrence of recombination …

The species problem has triggered the publication of an almost infinite number of theoretical
and practical studies, including quite a number of books. I should, therefore, perhaps briefly …

The naturally occurring genetic heterogeneity of autotrophic ammonia-oxidizing populations
belonging to the beta subclass of the Proteobacteria was studied by using a newly …

Phylogenetic species recognition and species concepts in fungi. Fungal Genetics and
Biology 31, 000–000. The operational species concept, ie, the one used to recognize …

Humans normally experience the conscious self as localized within their bodily borders. This
spatial unity may break down in certain neurological conditions such as out-of-body …

It is commonly assumed that the horizontal transfer of most bacterial chromosomal genes is
limited, in contrast to the frequent transfer observed for typical mobile genetic elements …

Genetic exchange is common among bacteria, but its effect on population diversity during
ecological differentiation remains controversial. A fundamental question is whether …

An ad hoc committee for the re-evaluation of the species definition in bacteriology met in
Gent, Belgium, in February 2002. The committee made various recommendations regarding …

Whole-genome sequencing (WGS) of bacterial isolates has become standard practice in
many laboratories. Applications for WGS analysis include phylogeography and molecular …
