Should there be a separate code of nomenclature for the protists?

Area of Science:

• * Taxonomy and Systematics
• * Protistology
• * Nomenclature

Background:

• * Existing Botanical and Zoological Codes of Nomenclature present challenges for classifying the diverse group of organisms known as protists.
• * Protists exhibit unique characteristics, including unicellularity, microscopic size, and wide dispersal across multiple taxonomic ranks and even kingdoms, complicating traditional classification.
• * The concept of a single kingdom Protista is no longer universally accepted, further challenging the applicability of kingdom-specific nomenclature codes.

Purpose of the Study:

• * To evaluate the adequacy of current botanical and zoological nomenclature codes for protists.
• * To explore the necessity and implications of establishing a separate nomenclature code for protists.
• * To address issues related to 'ambiregnal' species and the naming of suprafamilial protist taxa.

Main Methods:

• * Analysis of the limitations of existing international codes of nomenclature.
• * Review of the taxonomic and phylogenetic diversity of protists.
• * Examination of historical and current practices in protist classification.

Main Results:

• * Current nomenclature codes are inadequate for resolving classification issues unique to protists.
• * The wide taxonomic distribution of protists across multiple kingdoms challenges the principle of one code per kingdom.
• * The existence of 'ambiregnal' organisms and unresolved issues with suprafamilial naming highlight significant gaps.

Conclusions:

• * A distinct nomenclature code for protists is likely required to address their unique taxonomic and biological complexities.
• * The establishment of separate high-level ranks may be necessary for phylogenetically distinct protist groups.
• * Revisiting the fundamental principles of biological nomenclature is essential for accurate protist classification.
