Abstract

ABSTRACT Genetic data are increasingly being used to prioritize species conservation in a fiscally constrained age of seemingly boundless conservation crises. Such data can also reveal previously cryptic biodiversity requiring further revision of conservation management guidelines. Using a combination of mitochondrial (control region) and nuclear (beta fibrinogen intron 7) DNA, and morphology, we reveal that the endemic New Zealand Spotted Shag (Phalacrocorax punctatus) complex exhibits phylogenetic structure that is decoupled from previously recorded qualitative morphological variation. Crucially, the most genetically distinct populations within P. punctatus are from northern New Zealand; recent surveys show that these populations, which house important genetic diversity within Spotted Shags, are in danger of being extirpated. In contrast, we find the previously phenotypically differentiated nominate (P. punctatus punctatus) and Blue (P. punctatus oliveri) Shag subspecies show no genetic and morphological separation, and are of least conservation concern.

档案DNA揭示了新西兰斑点沙格（Phalacrocorax punctatus）内神秘的生物多样性

摘要：在一个财政拮据、保护危机似乎无限的时代，基因数据越来越多地被用来优先考虑物种保护。这些数据还可以揭示以前神秘的生物多样性，需要进一步修订保护管理指南。使用线粒体（对照区）和细胞核（β-纤维蛋白原内含子7）DNA以及形态学的组合，我们揭示了新西兰地方性斑点沙鼠（Phalacrocorax punctatus）复合体表现出与先前记录的定性形态学变异脱钩的系统发育结构。至关重要的是，P.punctatus中基因差异最大的种群来自新西兰北部；最近的调查显示，这些在斑点沙格体内拥有重要遗传多样性的种群正面临灭绝的危险。相反，我们发现先前表型分化的提名亚种（P.punctatus punctattus）和蓝色亚种（P.punctatus oliveri）Shag没有表现出遗传和形态分离，并且最不受保护。

期刊介绍： The Condor is the official publication of the Cooper Ornithological Society, a non-profit organization of over 2,000 professional and amateur ornithologists and one of the largest ornithological societies in the world. A quarterly international journal that publishes original research from all fields of avian biology, The Condor has been a highly respected forum in ornithology for more than 100 years. The journal is one of the top ranked ornithology publications. Types of paper published include feature articles (longer manuscripts) Short Communications (generally shorter papers or papers that deal with one primary finding), Commentaries (brief papers that comment on articles published previously in The Condor), and Book Reviews.
