Does anyone have a PDF?
Mitogenome sampling was too bad for this group in general, and particularly for
the three above. I tried what I could, but the whole thing was dangerously
unstable, too many main lineages with 1 leaf only. In particular Ciconia
ciconia basically did whatever it bloody well wanted, which was rarely
ND1 was the only mt locus (in fact the ONLY locus I have found) for which a
sufficient taxon sample* was available til now, and there Strisores and/or
cuckoos and/or trogons LBA into Aequornithes. Also included are, perhaps
significantly, NW vultures and bustards, which in some other loci stay well
away from long-legged aquatic birds. Interestingly NW vults wind up closer to
Gruiformes than bustards, which otherwise often pop up as basal Gruiformes more
often than the "Metaves" combined-data analyses would have you think.
(I did not include all Aequornithes, leaving out the "saltwater" group. Perhaps
including them will exclude Strisores et al?)
Thanks in advance,
* Pelecanus (at least 1, better 2, maybe best P.onocrotalus + P.conspicillatus
+ 1 OldWorld sp.), Balaeniceps, Scopus, Ciconiidae (at least 3, optimally
Mycteria/Jabiru etc + Ciconia + Ciconia/Leptotilos), Ardeidae (at least 3 -
heron, bittern, tiger-heron), Threskiornithidae (at least 2 - ibis & spoonbill.
Better: basal & advanced ibis + spoonbill).
Biggest problem in general is lack of thorough sampling of Ciconiidae &
Pelecanidae. At least mt sample for Ardeidae & Threskiornithidae usually
complete enough to work with.
