Table 4.
Test of alternative partitioning strategies.
| Partition Strategy | No. of Partitions | No. of parameters (ki) | Harmonic Mean Log-likelihood (Li) | AIC Score | BIC Score |
|---|---|---|---|---|---|
| Unpartitioned | 1 | 11 | -15185.35 | 30392.7 | 30544.7 |
| By gene | 4 | 48 | -14753.32 | 29602.6 | 30266.0 |
| By gene and codon | 8 | 82 | -14448.71 | 29061.4* | 30194.6* |
Modeltest selected the GTR+I+G model for all partitions except for codon position 1 in ND2 and ND4 (HKY+G), ND2 codon position 2 (GTR+I), ND2 codon position 3 and ND2 codon positions 2 & 3 (GTR+G). The asterisk indicates the optimal partitioning strategy.
