2.5 Phylogenetic analysis
Sequences were aligned and the substitution models and phylogenetic relationships were calculated using the software package MEGA 6.0 (Hall 2013; Tamura et al., 2013). Phylogenetic relationships of sequences were calculated using the model with the maximum likelihood (ML) method, which was assumed to describe the substitution pattern the best. Gaps were handled by partial deletion and bootstrap values were calculated out of 1000 replicates (Li 1997).
