皮肤组织样本的收集活组织检查飞镖从座头鲸（Megaptera novaeangliae）在六个季节性栖息地代表三个股票和四个地区：组IV（西澳大利亚州），V西部组件（东澳大利亚州），V东部组件（新西兰和汤加）和VI（南极半岛和戈尔戈纳岛，哥伦比亚，南美洲）的南半球。从这些个体中的84个个体中扩增并测序了线粒体DNA控制区的可变部分，总共区分出48个独特序列（即，mtDNA核型）。系统发育重建表明，这些核型形成三个分支，对应于那些以前在世界范围内的调查驼背鲸mtDNA变异，虽然自助支持的两个分支相对较低（
Samples of skin tissue were collected by biopsy darting from humpback whales (Megaptera novaeangliae) in six seasonal habitats representing three stocks and four regions: Groups IV (western Australia), V western component (eastern Australia), V eastern component (New Zealand and Tonga) and VI (the Antarctic Peninsula and Gorgona Island, Colombia, South America) of the Southern Hemisphere. A variable section of the mitochondrial DNA control region was amplified and sequenced from 84 of these individuals, distinguishing a total of 48 unique sequences (i.e., mtDNA nucleotypes). Phylogenetic reconstructions suggested that these nucleotypes form three clades, corresponding to those previously described in a world-wide survey of humpback whale mtDNA variation, although bootstrap support for two of the clades was relatively low (
