Table 5. Posterior probabilities and 95% confidence intervals (CI) for the most likely dispersal history scenarios when three equally likely scenarios (21, 26, 48) were compared against each other.

	Scenario #	PP 2x105	95% CI	PP 6x105	95% CI
NW Atlantic ancestral	48	0.2433	0.2318–0.2548	0.0688	0.0294–0.1082
Pacific ancestral	21	0.3569	0.3485–0.3653	0.5042	0.4900–0.5184
	26	0.399	0.3911–0.4084	0.427	0.4125–0.4415

Results from both maximum N_e max = 2 x 10⁵ and maximum N_e = 6 x 10⁵ are presented.
