1 of 49 checkable references need attention · checked 2026-08-03

At the dated check, the references listed below either did not resolve in Crossref or DataCite, or carried a retraction notice. Each one is shown with the registry record that put it there.

6 without a DOI — not checked. A reference deposited without a DOI is never matched by title or guessed at; it stays outside the checked set, and this line discloses that.

This chapter reports the classification of high ranks of the Bacteria and the Archaea, which is currently based on comparative analyses of rRNA and is supported by other markers and multigene approaches. The high information content and great availability in databases mostly justify the usage of rRNA gene sequences in taxonomy.

What this badge says. CiteStamped means the CHECKABLE references of this work were clean at the dated check: each resolved to a known work in a public registry, and none carried a retraction notice at that time. It says nothing about the quality, findings, or importance of the work itself, and nothing about references deposited without a DOI.
