BUSTED[S] fits for nonrecombinant segments.

For each segment, 2 rows of numbers are presented: top—for the BUSTED[S]-HMM model and bottom—for the BUSTED[S] model, allowing for multinucleotide substitutions (see Lucaci and colleagues [45] for details). The model with the better AIC-c and significant test results (p-value) are shown in bold. CV synonymous rate variation (SRV): coefficient of variation (CV) of the site-to-site synonymous rate distribution. ƛ: the rate of double-nucleotide substitutions (relative to the rate of single-nucleotide synonymous substitutions); ẟ: the relative rate of triple nucleotide substitutions; δislands: the relative rate of triple nucleotide substitutions that involve synonymous codons, e.g., for Serine.
