自 1981 年以来，在英国东南部内陆建立的鸬鹚繁殖地是一个主要的保护和害虫管理问题。这项研究的目的是调查两个最近建立的繁殖群体的亚种起源。该分析检查了线粒体基因组控制（D 环）区域的序列变异。组织样本取自西欧整个物种范围的 334 只亚种（Phalacrocorax carbo carbo 和 P. c. sinensis）个体以及来自英国两个爱尔兰繁殖地的 84 只鸟类。单链构象多态性（SSCP）用于评估样品之间的线粒体变异，揭示了四种单倍型。来自传统繁殖群体的样本分为三个不同的系统地理学分组：挪威-苏格兰、威尔士-英格兰-肖西岛和欧洲大陆的其他地区。这些结果仅部分符合传统的亚种分类学分组，并且与使用微卫星 DNA 频率的结果略有不同，并且提出了使用两项研究结果的假设。使用最大似然模型和贝叶斯模型研究了内陆菌落的亚种起源。
The establishment of cormorant breeding colonies inland within south-east Britain since 1981 is a matter of major conservation and pest management concern. This study was initiated to investigate the subspecific origin of two recently established breeding colonies. The analysis examined sequence variation of the control (D-loop) region of the mitochondrial genome. Samples of tissue were obtained from 334 individuals from across the species range in western Europe from both subspecies (Phalacrocorax carbo carbo and P. c. sinensis) and 84 birds from two ireland breeding colonies in Britain. Single-strand conformation polymorphism (SSCP) was used to assess mitochondrial variation among samples, revealing four haplotypes. The samples from the traditional breeding colonies clustered into three distinct phylogeographic groupings: Norway-Scotland, Wales-England-Iles des Chausey and the rest of Continental Europe. These results only partly agree with the traditional subspecific taxonomic groupings and are slightly at variance with results using microsatellite DNA frequencies, and a hypothesis using results from both studies is advanced. The subspecific origin of the inland colonies was investigated using maximum likelihood and Bayesian models.
