False killer whales (Pseudorca crassidens) are large delphinids typically found in deep water far offshore. However, in the Hawaiian Archipelago, there are 2 resident island-associated populations of false killer whales, one in the waters around the main Hawaiian Islands (MHI) and one in the waters around the Northwestern Hawaiian Islands (NWHI). We use mitochondrial DNA (mtDNA) control region sequences and genotypes from 16 nuclear DNA (nucDNA) microsatellite loci from 206 individuals to examine levels of differentiation among the 2 island-associated populations and offshore animals from the central and eastern North Pacific. Both mtDNA and nucDNA exhibit highly significant differentiation between populations, confirming limited gene flow in both sexes. The mtDNA haplotypes exhibit a strong pattern of phylogeographic concordance, with island-associated populations sharing 3 closely related haplotypes not found elsewhere in the Pacific. However, nucDNA data suggest that NWHI animals are at least as differentiated from MHI animals as they are from offshore animals. The patterns of differentiation revealed by the 2 marker types suggest that the island-associated false killer whale populations likely share a common colonization history, but have limited contemporary gene flow.
伪虎鲸（Pseudorca crassidens）是大型海豚科动物，通常见于远离海岸的深水区。然而，在夏威夷群岛，有两个与岛屿相关的伪虎鲸定居种群，一个在夏威夷主要岛屿（MHI）周围海域，另一个在夏威夷西北部岛屿（NWHI）周围海域。我们使用来自206个个体的线粒体DNA（mtDNA）控制区序列和16个核DNA（nucDNA）微卫星位点的基因型，来研究这两个与岛屿相关的种群以及北太平洋中部和东部近海动物之间的分化程度。mtDNA和nucDNA在种群之间均表现出高度显著的分化，证实了两性之间的基因流动有限。mtDNA单倍型呈现出强烈的系统地理学一致性模式，与岛屿相关的种群共享3种密切相关的单倍型，这些单倍型在太平洋其他地方未被发现。然而，nucDNA数据表明，NWHI的动物与MHI的动物之间的分化程度至少与它们与近海动物之间的分化程度相同。两种标记类型所揭示的分化模式表明，与岛屿相关的伪虎鲸种群可能有着共同的殖民历史，但当代基因流动有限。
