Table 1: Molecular diversity indices for A. abdominalis, C. ovalis, and C. verater. Number of individuals (), number of haplotypes (), nucleotide diversity (), haplotype diversity (), and Fu’s are listed for cytb and CR. values in bold are significant (P < 0.05). For A. abdominalis, populations at Gardner Pinnacles () and Nihoa () were not included in most analyses due to small sample sizes.
