New invader in the Polish Baltic Sea Proper: phylogeny and global distribution of Calyptospadix cerulea Clarke, 1882 (Cnidaria, Hydrozoa)

Figure 3.

Maximum likelihood reconstruction of Calyptospadix cerulea Clarke, 1882 (in bold) phylogenetic position, based on a concatenated set of molecular markers (16S rRNA, COI, 18S rRNA), with bootstrap values showed near the nodes. Marker-specific substitution models identified with ModelFinder were: GTR+F+I+G4 (COI) and TIM2+F+I+G4 (16S rRNA and 18S rRNA). Family-level assignments are color coded. Calyptospadix cerulea spec. 1 and spec. 2 indicate two separate colonies sequenced in this study.
