Substitution models selected by the Akaike Information Criterion in Modeltest for each dataset, with substitution matrices (x >y indicating mutation from nucleotide x to nucleotide y), Ti/Tv = transition/transversion rates, α = shape of gamma distribution, I = proportion of invariable sites, and base frequencies (A, C, G, T) in percentage. GTR + I = General Time Reversible + Invariable model; GTR + Gamma = General Time Reversible + Gamma model; TRN + G = Tamura Nei + Gamma model; HKY + I + G = Hasegawa-Kishino-Yano + Invariable + Gamma model; TVM + I + G = Transition Model + Invariable + Gamma model.
