Abstract

Abstract Implementing efforts to understand biogeographic distribution patterns and taxonomic limits within animal groups is crucial for addressing several challenges of modern zoology. Although avian phylogeography has been extensively investigated within the Western Palearctic, several families, such as shrikes, still display unresolved or neglected biogeographic patterns both between and within species, thus requiring further investigations. The Woodchat Shrike (Lanius senator) is a long-distance migratory species that exhibits three morphologically well-recognizable subspecies, whose boundaries have never been phylogenetically investigated. Here, we aimed to define the phylogeographic structure of Lanius senator throughout its breeding range and assess the genetic coherence with respect to the phenotypically described subspecies. We assembled a collection of 34 samples mainly from breeding populations of each subspecies and analysed them using four mtDNA and two nuDNA markers. We did not find clear phylogenetic structure in nuclear Ornithine Decarboxylase (ODC) and Myoglobin intron 2 (MYO), but all the four mtDNA loci (i.e., ND2, COI, cytb and CR) highlighted two main haplogroups: one including both the nominate subspecies L. s. senator and L. s. badius and a second one consisting of L. s. niloticus (the easternmost part of its range). Surprisingly, individuals phenotypically assigned to L. s. niloticus from Israel were genetically assigned to the senator/badius haplogroup. Moreover, genetic distances between haplogroups showed intermediate values between inter-intraspecies diversity usually reported for Passerines. We estimated a divergence time at ca. 890 kya (554–1.259 kya HPD). Our findings showed a mismatch in subspecies assignment using morphology and genetic information and a marked differentiation between the eastern L. s. niloticus and all other L. senator populations sampled.

其繁殖区的种地理学:α分类、亚种分布与遗传的冲突

了解动物类群的生物地理分布模式和分类学限制对于解决现代动物学的几个挑战至关重要。尽管鸟类系统地理学已经在西古北纬地区进行了广泛的研究，但一些科，如伯劳鸟，在物种之间和物种内部仍然表现出未解决或被忽视的生物地理模式，因此需要进一步的研究。Woodchat伯劳鸟(Lanius senator)是一种长距离迁徙的物种，具有三个形态上很好识别的亚种，其边界从未被系统发育研究过。在这里，我们的目的是确定拉尼乌斯在其整个繁殖范围内的系统地理结构，并评估相对于表型描述的亚种的遗传一致性。我们收集了主要来自每个亚种繁殖种群的34个样本，并使用4个mtDNA和2个nuDNA标记对它们进行了分析。我们在核鸟氨酸脱羧基酶(ODC)和肌红蛋白内含子2 (MYO)中没有发现明确的系统发育结构，但所有4个mtDNA位点(即ND2、COI、cytb和CR)都突出了两个主要的单倍群:一个包括指定亚种L. s. senator和L. s. badius，第二个包括L. s. niloticus(其范围的最东端)。令人惊讶的是，表型上属于以色列L. s. niloticus的个体在遗传上属于参议员/巴迪乌斯单倍群。此外，单倍群之间的遗传距离在雀形目的种内多样性之间表现出中间值。我们估计辐散时间约为890 kya (554-1.259 kya HPD)。研究结果表明，利用形态学和遗传信息进行亚种分配存在不匹配，东部niloticus与其他所有取样的L. senator种群之间存在显著差异。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
