amendments to the Constitution of the International Commission on Zoological NomenclaturE

The International Commission on Zoological Nomenclature recently made available to the community proposed amendments to its Constitution for feedback from the zoological community on them. Along with amendments to its Bylaws, this proposed amendment to the Constitution of the ICZN will help the Commission clarify its position in fulfilling its aim of promoting stability and universality in nomenclature.

The amendment was published in the Bulletin of Zoological Nomenclature, ZooKeys, Zootaxa, and the European Journal of Taxonomy, indicating a one-year period within which comments could be submitted, ending 30 April 2021. 

The amended Constitution was ratified by the International Union of Biological Sciences (IUBS) in June 2022.
