Bibliography of studies on hybrid zones of the common shrew chromosome races distributed in Russia

The common shrew, Sorex araneus Linnaeus, 1758, has become a model species for cytogenetic and evolutionary studies after discovery of extraordinary Robertsonian polymorphism at the within-species level. Development of differential staining techniques (Q-, R-and G-banding) made it possible to identify the chromosomal arms and their combination in racial karyotypes. Entering into contact with each other, the chromosomal races might form hybrid zones which represent a great interest for understanding of the process of speciation. Until recently all known hybrid zones of S. araneus were localized in Western Europe and only one was identified in Siberia (Russia) between Novosibirsk and Tomsk races (Aniskin and Lukianova 1989, Searle and Wójcik 1998, Polyakov et al. 2011). However, a rapidly growing number of reports on discovery of interracial hybrid zones of Sorex araneus in the European part of Russia and neighboring territories appeared lately. The aim of the present work is to compile the bibliography of all studies covering this topic regardless of the original language and the publishing source which hopefully could make research data more accessible to international scientists. It could also be a productive way to save current history of Sorex araneus researches in full context of the ISACC (International Sorex araneus Cytogenetics Committee) heritage (Searle et al. 2007, Zima 2008).

普通鼩鼱（Sorex araneus Linnaeus, 1758）自其种内存在显著的罗伯逊易位多态性被发现后，已成为细胞遗传学与进化生物学研究的模式物种。差分染色技术（Q显带、R显带、G显带）的发展，使得研究者能够精准区分染色体臂，并明确不同染色体种族核型中的染色体臂组合模式。不同染色体种族相互接触后可形成杂交带，该类杂交带为解析物种形成过程提供了关键研究模型。直至此前，所有已报道的普通鼩鼱杂交带均分布于西欧，仅在俄罗斯西伯利亚的新西伯利亚种族与托木斯克种族之间发现过一处（Aniskin与Lukianova 1989、Searle与Wójcik 1998、Polyakov等2011）。但近年来，关于在俄罗斯欧洲部分及邻近区域发现普通鼩鼱种间杂交带的研究报道日益增多。本研究旨在收集整理该主题下所有相关研究的参考文献，无论其原始语言与发表载体，以期为国际科研人员提供更便捷的研究数据获取途径。同时，本研究也可完整留存普通鼩鼱细胞遗传学研究的历史脉络，契合国际普通鼩鼱细胞遗传学委员会（International Sorex araneus Cytogenetics Committee, ISACC）的研究传承（Searle等2007、Zima 2008）。
