On A Global List Of Species

Brianne Du Clos · December 23, 2025

My last batch of papers linked me to a vibrant debate that took place in the literature from 2017-2018, resulting in a working group, a journal article collection, and a PNAS Perspective (sounds a lot like the Bee Monitoring RCN!) on the need for a single global list of species. I was familiar with one of these papers (Thomson et al. 2018), but not the full context in which it was produced, and this has been a fascinating bunch of reading. It admittedly is the opposite take on the issue from the last batch of papers, which seemed to be against the centralization of nomenclature. But I am really into reading both sides and orienting to all the nuance that underlies how species names can be represented in occurrence data and conservation applications. Here’s what I have been reading lately:

I’d like to read the six articles in the collection linked above, too; then, I plan to read a couple back and forths in the literature on this issue specific to WoRMS. I feel like something is churning on all this reading, but I’m not sure what that is yet…
