Fortuynia e. micromorpha

TCS haplotype network analysis of COI sequence data of F. e. micromorpha populations showed relatively high genetic

Table 2 statistics of investigated populations of the South African Fortuynia e. micromorpha and Halozetes capensis diversity by identifying 29 different haplotypes in 121 specimens. One haplotype is shared by numerous individuals from all populations and most other haplotypes are separated from this haplotype only by a single mutation ( Fig. 3 ). No geographic clustering of haplotypes can be recognized, except for a small cluster formed by several haplotypes from Mtwalume. Sheffield shows the highest genetic (haplotide) diversity with 10 different haplotypes and Port Edward the lowest with just a single haplotype (Table 2), which is not surprising as we could only find specimens in a single spot there. Pairwise population differentiation resulted in overall moderate θST and ΦST values ( Table 3), indicating gene flow between all populations. Lowest values are shown between Umdloti and Umkomaas reflecting the highest connectivity between these two populations, and highest values are shown between Umdloti and Mtwalume pointing to more restricted gene flow between these populations.
