Taxacom: Kingdom Protista (minor revisions)

[Kenneth Kinman]

Followup:
         Today I've been looking at my classification of Kingdom Protista and comparing it with Adl et al. and Ruggiero et al.  I have decided to follow Cavalier-Smith himself and show Percolozoa splitting off alone right after Euglenozoa (and then Loukozoa, then Metamonada).  Goodbye to Ruggiero's et al.'s Infrakingdom Excavata (especially since it excludes the Euglenozoa which are also excavates).
         I have also decided to make one addition, a Phylum Varisulca, even though it may need to be split when their phylogeny is settled (still a controversial mess).   Anyway, the cladistic coding to the left of the taxa in my classification needed to be changed to reflect these modifications (as follows):

   1   Euglenozoa
   2   Percolozoa
   3   Loukozoa
   4   Metamonada

  5A  Varisulca (incl. CRuMs) paraphyletic?

   B   Amoebozoa

   C  Breviatea
   D  Apusozoa
   E  "Archeopisthokonta" (Choanozoa sensu lato)%%
 _a_   {{Kingdom EUMYCOTA}} (true fungi)
 _b_   {{Kingdom METAZOA, aka ANIMALIA}}

  6A  Glaucophyta

            etc.

Subject: Kingdom Protista (protists)

Hi All,
        I haven't worked on my Kingdom Protista classification for a while.  But what I used to call Phylum Choanozoa (sensu lato) would probably best be called Archaeopisthokonta since it gave rise to the two major kingdoms of opisthokonts (Animalia and Eumycota/Fungi).  It is marked %% since it is doubly paraphyletic.  Phylum Chlorophyta% is singly paraphyletic (giving rise to one Kingdom Metaphyta (Embryophyta).  Everything else in the classification below is cladistic (coded with the numbers and letters to the left).  Although I am heavily influenced by Cavalier-Smith's research (and his producing classifications with limited paraphyly), I prefer to mark paraphyletic groups with a % symbol rather than a simple *, since a paraphyletic group is just a basal percentage of a larger clade.

                KINGDOM PROTISTA%%%
   1   Euglenozoa
  2A   Percolozoa
   B    Loukozoa
   C   Metamonada
  3A   Amoebozoa

   B   Breviatea
   C   Apusozoa
   D   "Archeopisthokonta" (Choanazoa sensu lato)%%
 _a_   {{Kingdom EUMYCOTA}} (true fungi)
 _b_   {{Kingdom METAZOA, aka ANIMALIA}}
  4A   Glaucophyta
   B   Rhodophyta
   C   Chlorophyta%
 _a_   {{Kingdom METAPHYTA}} (embryophytes)
  5A   Cryptista (cryptophytes)
   B   Haptista (haptophytes)
   6   Rhizaria
   7   Heterokonta (stramenopiles)
   8   Ciliophora
   9   Dinozoa (or Dinophyta)
  10  Sporozoa


----------------------------------------------
NOTES:

Clade 3D is Opisthokonta.

Clade 3 is Unikonta,

Clade 4 is Archaeplastida,

Clade 5 is Hacrobia.

Clades 6-10 make up the "SAR" clade.

Clades 5-10 might be called Chromista "sensu lato".

Clades 4-10 form the Bikonta (aka Photokaryota or Diaphoretickes) clade.

Clades 3-10 form Cavalier-Smith's "Neozoa";

Clades 2-10 form Cavalier-Smith's "neokaryotes".
