Statistical analysis of the bathymetric distribution

The comparison of the bathymetric distribution of specimens of Dendronotus robustus and D. velifer which were involved in the molecular taxonomic analysis (see above) reveal significant statistical differences (p=0.002, Figure 4c). The bathymetric data for historical specimens of D. velifer and for recently collected D. robustus demonstrate statistically significant differences (p <0.001, Figure 4c; right lilac and left blue bars). At the same time, the bathymetric data between historical specimens of D. velifer and the recently collected specimens of D. velifer do not show any significant differences (Figure 4c).
