[Taxacom] Catalogue of Life (CoL) management classification draft document

You could use the "supergroup" classification of Parfrey et al.  
(2006), as I have done (currently) on Wikispecies:

http://species.wikimedia.org/wiki/Eukaryota#References

This has the advantage of fewer main clades...

Quoting Tony.Rees at csiro.au:

> Dear David, all,
>
> I've taken a look at the classification at  
> http://eutree.lifedesks.org/ bearing in mind that as you say, it is  
> a working rather than a reference structure. For example, the  
> highest level categories under "Eukaryota" look like this:
>
> Eukaryota
>
> # Amoebozoa
> # Ancyromonas
> # Apusomonads
> # Breviatea
> # Centroheliozoa
> # Cryptomonads+kathablepharids
> # Excavates
> # Glaucocystophytes
> # Haptophytes
> # Micronuclearia
> # Opisthokonts (incl. Choanoflagellates+animals,  
> Chytrids+fungi+microspora, plus more)
> # Paramyxea
> # Residua (includes acritarchs, residual algae, residual amoebae,  
> chitinozoa plus more)
> # Rhodophyta
> # SAR hypothesis (=Alveolates and Stramenopiles+Rhizaria)
> # Telonemidae
> # Viridaeplantae
>
> I think you will agree, though, that it may not be very suitable for  
> porting into the CoL style of hierarchy which really works around  
> the kingdom/phylum/class/order system, unless you are happy for all  
> of the above to be phyla (or perhaps kingdoms...) Is there anything  
> from the above that would be a better fit for CoL needs than the  
> alternative suggested in Dennis' paper?
>
> I guess the other issue for CoL is that they probably need to cite a  
> "published" classification (e.g. with versioning) that can be  
> superseded at some later point, than a continuously evolving web  
> product (however accurate this may be)...

> To answer Tony's question, No there is still no consensus over how  
> to handle the protists.  Molecular analyses have tended to add a  
> fair bit of noise to the picture, this has led to many speculations  
> expressed in the form of classificatory structures, and the  
> consequence is a lot of confusion.  Some parts of the scheme appear  
> to be increasingly robust, although the scope and definition of the  
> taxa remain uncertain.  Survivors at the top level seem to be the  
> Opisthokonts (animals, fungi and close protistan relatives),  
> Amoebozoa and Rhizaria.  Excavates go in an out of favor, while  
> chromalveolates and Archaeplastida are not solid.  Similarly, at  
> more distal points in the conceptual tree, some taxa, such as  
> Chromists, are unsupported by much beyond wishful thinking and so  
> are contentious.
>
> Ideally, the application of phylogenetic principles as criteria for  
> retention or dismissal of taxa would be wonderful, and  
> protistologists have been somewhat slow to move in this direction.
>
> A protist classification that is more consistent with currently  
> available data can be found at eutree.lifedesks.org.  It is a  
> working structure rather than a reference structure.  In that  
> system, if relationships are unclear, the contestants for most  
> proximate neighbors are placed as sister groups to minimize the risk  
> of producing polyphyletic taxa.
>
> As an interesting aside, the eutree classification was built from a  
> decade-old classification that had been based mostly on premolecular  
> data.  The conversion required fewer than 100 edits.  Those edits  
> included the addition of several previously missing genera and  
> species. That is, the somewhat costly molecular studies of the last  
> decade have led to about 70 discrete improvements in our knowledge  
> of this area.
