摘要

安纳托利亚山蛙包括两个被承认的物种(Rana macrocnemis和Rana tavasensis)，这个群体以其遍布安纳托利亚山脉的高陆地分布而闻名。尽管这些群体(冷适应和高原物种)具有独特的特征，但它们的种群遗传学尚未被揭示。利用6个微卫星标记，研究了安那托利亚山蛙在 rkiye自然分布区的等位基因变异和遗传结构。我们评估了来自31个地点的138个样本，并基于结构分析对它们进行了聚类。微卫星标记表明，东安纳托利亚群体具有较高的遗传多样性，而中金牛座和西安纳托利亚群体的遗传多样性有限。研究发现，在中央金牛座群体中存在明显的瓶颈现象，大孔金牛座和塔瓦斯金牛座之间没有遗传分化。结果表明，由于宏观和微观气候的原因，安纳托利亚山蛙表现出潜在的近亲繁殖迹象。

Microsatellite variation and population genetic structure of Anatolian mountain frogs

Anatolian mountain frogs consist of two admitted species (Rana macrocnemis and Rana tavasensis), and this group is famous for its high land distribution throughout the Anatolian mountain chain. Despite the unique features of these groups (cold-adapted and highland species), their population genetics have yet to be revealed. In this study, the allelic variation and genetic structure of Anatolian mountain frogs were investigated using six microsatellite markers across its natural distribution area in Türkiye. We evaluated 138 samples from 31 locations and clustered them based on a Structure analysis. The microsatellite markers suggested a high level of diversity in the East Anatolia cluster, while we found limited genetic diversity in the Central Taurus and West Anatolia clusters. We found a significant bottleneck in the Central Taurus cluster, with no genetic differentiation between R. macrocnemis and R. tavasensis. Our results show that the Anatolian mountain frogs exhibit underlying inbreeding signs for macro and microclimatic reasons.
