SummaryCook’s Petrel Pterodroma cookii is an endemic New Zealand seabird that has experienced a large range decline since the arrival of humans and now only breeds on two offshore islands (Te Hauturu-o-Toi/Little Barrier Island and Whenua Hou/Codfish Island) at the extreme ends of its former distribution. Morphological, behavioural, and mitochondrial cytochrome oxidase 1 (CO1) sequence data led a previous study to recognise the two extant populations as distinct conservation management units. Here, we further examine the genetic relationship between the extant populations using two nuclear introns (β-fibint7 and PAX). Using one mitochondrial locus (CO1), we also investigate the past distribution of a single nucleotide polymorphism (SNP) that differentiates the modern populations using bone and museum skins sourced from within its former range across New Zealand’s North and South Islands. We found significant population genetic structure between the two extant Cook’s Petrel populations for one of the two nuclear introns (β-fibint7). The mitochondrial DNA CO1 analysis indicated that the SNP variant found in the Codfish Island population was formerly widely distributed across both the North and South Islands, whereas the Little Barrier Island variant was detected only in North Island samples. We argue that these combined data support the recognition of the extant populations as different subspecies. Previous names for these taxa exist, thus Cook’s Petrel from Little Barrier Island becomes Pterodroma cookii cookii and Cook’s Petrel from Codfish Island becomes P. c. orientalis. Furthermore, we suggest that both genetic and non-genetic data should be taken into consideration when planning future mainland translocations. Namely, any translocations on the South Island should be sourced from Codfish Island and future translocations on the North Island should continue to be sourced from Little Barrier Island only.

Cook's Petrel Pterodroma cookii 亚种指定的综合证据对保护管理有影响

摘要库克的海燕紫檀是新西兰特有的海鸟，自人类到来以来经历了大范围衰退，现在只在其最末端的两个近海岛屿（Te Hauturu-o-Toi/Little Barrier Island 和Whenua Hou/Codfish Island）繁殖。前分布。形态、行为和线粒体细胞色素氧化酶1(CO1) 序列数据导致之前的一项研究将这两个现存种群识别为不同的保护管理单位。在这里，我们使用两个核内含子进一步检查了现存种群之间的遗传关系（β-fibint7和帕克斯）。使用一个线粒体基因座 (CO1)，我们还调查了单核苷酸多态性 (SNP) 的过去分布，该单核苷酸多态性 (SNP) 使用来自新西兰北岛和南岛以前范围内的骨骼和博物馆皮肤来区分现代人群。我们在两个现存的库克海燕种群之间发现了两个核内含子之一的显着种群遗传结构（β-fibint7）。线粒体 DNA CO1 分析表明，在鳕鱼岛种群中发现的 SNP 变体以前广泛分布在北岛和南岛，而小屏障岛变体仅在北岛样本中检测到。我们认为，这些综合数据支持将现存种群识别为不同的亚种。这些分类群的先前名称存在，因此来自 Little Barrier Island 的 Cook's Petrel 变为凤尾蕨和鳕鱼岛的库克海燕变成个人电脑。东方人. 此外，我们建议在规划未来的大陆易位时应考虑遗传和非遗传数据。也就是说，南岛的任何易位都应来自鳕鱼岛，而北岛未来的易位应继续仅来自小屏障岛。
