Fiord populations of Astrobrachion constrictum (Ophiuroidea: Asteroschematidae) show little genetic differentiation for mitochondrial DNA

Figures & data

Figure 1 Fiordland region of South Island, New Zealand, showing collection locations for the snake star Astrobrachion constrictum. Doubtful Sound sites are: 1, Espinosa Point; 2, Tricky Cove; 3, Oz; 4, Crowded House.

Figure 2 Minimum spanning network for eight snake star COI haplotypes (A–H; Table 1) constructed from sequence data. Black dots on the C and D lineages indicate hypothetical intermediates. Sample size (as assessed by SSCP) is reflected by area of each circle.

Table 1 Summary of COI SSCP haplotype data for snake stars from Nancy Sound, Chalky Inlet and Preservation Inlet, and four sites within Doubtful Sound (Espinosa Point, Tricky Cove, Oz, Crowded House).
