Taxacom: Fwd: Two or more authors: language

Wed Aug 6 06:35:34 CDT 2025

An AI response to a query I just made after reading this exchange provided an interesting answer, but I am not suggesting that we should blindly follow what a machine suggests!

- I copy and paste verbatim:

Botanical Nomenclature: Governed by the International Code of Nomenclature for algae, fungi, and plants (ICN).
Zoological Nomenclature: Governed by the International Code of Zoological Nomenclature (ICZN).

Both codes emphasize stability and clarity, and et al. remains the accepted abbreviation when citing multiple authors. The ICZN, for instance, does not allow changes like replacing et al. with & al. in formal naming.
Unfortunately, there are no published quantitative statistics comparing the frequency of ?et al.? vs ?& al.? or other variants in botanical or zoological literature. However, here are some qualitative observations:

  *   Academic Journals and Databases (e.g., ZooBank, IPNI, Tropicos) overwhelmingly use et al. in author citations.
  *   ?& al.? is more likely to appear in:
     *   Informal writing or older texts
     *   Non-standardized databases or OCR-scanned documents
  *   Trend Toward Simplification: In digital platforms and casual contexts, there's a mild tendency to drop Latin formalism, but this hasn't penetrated formal nomenclature.

I suspect many botanists are also moving to using "&". It is used by IPNI, Plants of the World Online, and World Flora Online. It is like Leguminosae and Fabaceae. They are equally acceptable, but today Fabaceae is the more frequently encountered in online resources.

My feeling (which I believe is correct) is that botanical tradition is to
use a bit more Latin than zoological tradition (these days). So a botanical
work is more likely to say (e.g.) Smith et Jones, 1905, while a zoological
work would use Smith & Jones, 1905. For my compendium, which spans both
botanical and zoological names (the latter outnumber the former by around
4:1), I standardise everything to a single format, using "&" and not "et"
to link names together ("et al." being an exception).
