许多滨鸟物种有广泛的地理分布，包括几个大洲。由于滨鸟是优秀的飞行者，可以迁徙很长的距离，因此通常不清楚亚种和来自不同大陆的种群之间是否存在生殖障碍。肯氏雪鸟（学名：Charadrius alexandrinus）是世界性的滨鸟。美洲和欧亚亚种--雪普洛弗和肯特郡普洛弗--是否分别构成一个单一的物种是一个长期争论的主题。我们通过比较美洲亚种C的遗传和表型特征，研究了美洲和欧亚种群之间的差异，以重新评估当前的分类学。a. nivosus和欧亚亚种C. a.来自七个种群的亚历山大兽。遗传分析表明，美洲和欧亚种群有很大的分歧，肯特普洛弗更接近于白额普洛弗（C。而不是雪普洛弗。这些结果在所有评估的核标记（26个微卫星和部分CHD序列）和两个线粒体标记（ND 3和ATP酶6/8）之间是一致的。在亚种内，跨越较大地理距离取样的种群没有遗传分化（所有F（st））
Many shorebird species have widespread geographic distributions comprising several continents. Because shorebirds are excellent flyers and can migrate large distances, it is often unclear whether reproductive barriers between subspecies and populations from different continents exist. Kentish-Snowy Plovers (Charadrius alexandrinus) are cosmopolitan shorebirds. Whether the American and Eurasian subspecies-Snowy Plover and Kentish Plover, respectively-constitute a single species is the subject of a longstanding debate. We examined the divergence between American and Eurasian populations to reassess the current taxonomy by comparing genetic and phenotypic characters of the American subspecies C. a. nivosus and the Eurasian subspecies C. a. alexandrinus from seven populations. Genetic analyses revealed that American and Eurasian populations have strongly diverged, the Kentish Plover being more closely related to the White-fronted Plover (C. marginatus) than to the Snowy Plover. These results were consistent across all assessed nuclear markers (26 microsatellites and a partial CHD sequence) and two rnitochondrial markers (ND3 and ATPase 6/8). Within subspecies, populations sampled across large geographic distances were not genetically differentiated (all F(st)
