[Taxacom] Taxonomic anarchy -- solution?

One role of the IUCN SG's is to synthesis the known taxonomy of their
specialist group, they do not add to it per se, just summaries it
constantly is one way of looking at it. Within the IUCN SSG Turtle and
Freshwater Turtle Specialist Group (TFTSG) we have the Turtle Taxonomy
Working Group and the Turtle Extinctions Working Group, these two basically
do this for living and fossil turtles respectively and produce constantly
updated checklists that are based on the taxonomic literature, these are
peer reviewed. Checklists have their issues, some of which were discussed
by Pauly et al. 2009 (
http://www.webpages.uidaho.edu/~jacks/Pauly.et.al.09.pdf). However, as long
as these are peer reviewed and are constructed by people with a knowledge
and understanding of taxonomy it can be minimized.

TFTSG Checklist is here: http://www.iucn-tftsg.org/checklist/
