ENC, Effective Number of Codons. CBI, Codon Bias Index. SChi2, Scaled Chi Square. G+C2, G+C content at the second codon positions. G+C3s, G+C content at (synonymous) the third codon position; i.e. the G+C content in the third codon position excluding Trp and Met codons (nuclear universal genetic code). G+Cc, G+C content at codon positions. Species names are as in Table 1.
