This is the archive of the minutes from online meetings of the Ad Hoc Committee on Mitigating Changes in Prokaryotic Nomenclature (CoMiCProN). The minutes are authored by either the Chairman or the Secretary of the CoMiCProN and are versioned according to the date of the meeting. CoMiCProN is a subcommittee of the International Committee on Systematics of Prokaryotes (ICSP) and pursues its objectives in accordance with the International Code of Nomenclature of Prokaryotes (ICNP). For example, to mitigate bacterial name changes, it is important to inform agencies, databases, journal authors, reviewers and editors that most bacterial name changes are not mandatory under the ICNP, although they may be perceived as such. CoMiCProN aims to recognise both the need for taxonomic classification to reflect empirical data and the need to reduce name changes as much as possible. A future goal is to provide specific recommendations for naming in accordance with these principles.
