鸟类的大规模迁徙已经通过环鸟的回收得到了广泛的研究。然而，来自北极涉水动物繁殖地的振奋人心的数据非常少。本文利用群体遗传标记技术，研究了高山金龟子的迁徙模式，利用单倍型频率估计迁徙和越冬种群的繁育来源。利用聚合酶链式反应(PCR)和线粒体控制区DNA限制性内切酶分析，研究了西部古北区冬季种群形态相似的繁殖起源，描述了都林犬冬季种群结构。也从欧洲、非洲和亚洲的不同中途停留地点迁徙的敦林，分析了它们的线粒体DNA(MtDNA)单倍型。遗传标记表明，都灵种群具有平行的迁徙系统，在古北界西部繁殖的种群主要在越冬山脉的西部越冬，而都灵种群则在更东的地方越冬。结果还表明，该地区越冬区与繁殖区之间的距离向东增大。
The large‐scale migration of birds has been studied extensively by recoveries of ringed birds. However, there is very little ringing data from the arctic breeding grounds of waders. Here, the migration pattern of the dunlin, Calidris alpina, is studied with population genetic markers, using haplotype frequencies to estimate the breeding origin of migrating and wintering populations. Polymerase chain reaction (PCR) and restriction analysis of DNA from the mitochondrial control region was used to study the breeding origins of morphologically similar winter populations in the western Palaearctic, and to describe the population structure of the dunlin during winter. Also migrating dunlin from various stopover sites in Europe, Africa and Asia, were analysed with respect to their mitochondrial DNA (mtDNA) haplotypes. The genetic markers clearly show that the dunlin has a parallel migration system, with populations breeding in the western Palaearctic wintering mainly in the western part of the wintering range, and dunlin populations breeding further east wintering further east. The results also show that the distance between breeding and wintering area increases eastwards in this region.
