Table 1.
Molecular diversity indices for mitochondrial cytochrome b (cyt b) sequences. Lutjanus fulvus and C. argus = cyt b (data for source populations from Gaither et al. [31,32], respectively), L. kasmira = control region (data from Gaither et al. [29]); Hawai‘i Island and Maui in the current table = Kona + Hilo and Maui Nui in original dataset, respectively); data in parentheses are cyt b data generated from a subset (N = 189 of 484) of the samples from Gaither et al. [29]. Number of specimens (n), number of haplotypes (nh), haplotype diversity (h) and nucleotide diversity (π) as reported by Arlequin v. 3.5 [36] are listed. FFS, French Frigate Shoals. Source locations = Nuku Hiva, Marquesas Islands; Moorea, Society Islands; Kanton, Phoenix Islands.
