a ωo indicates the initial seed value of ω used.
b 2δ, two times the difference of the natural log values of the maximum likelihood from pairwise comparisons of the different models.
c Tree length is defined as the sum of the nucleotide substitutions per codon at each branch.
d Residue numbers are based on dog (CARenvV) and cattle (ARTenvV) protein sequences.
e pr, posterior probability.
* Indicates residues identified under positive selection via the datamonkey webserver.
