Abstract

In this study, the phylogeny of Alburnus genus distributed in Turkish freshwaters was performed by analyzing mitochondrial cyt b gene (1141 bp) and COI gene (1551 bp) sequences from 1172 samples representing 112 populations of 24 species through their geographical distribution. According to our findings, 20 valid species are distributed in Turkey of which 18 have already been known. While six Alburnus species (A. battalgilae, A. istanbulensis, A. carinatus, A. schischkovi, A. nasreddini ve A. adanensis) have been synonomized, two new species (Alburnus sp.1 and Alburnus sp.2) from Dicle River and Çapraz Stream/Susurluk River have been identified. Extinct species such as A. akili and A. nicaeensis have not been observed in situ. Phylogenetic tree topologies and haplotype network of the 119 cyt b and 80 COI haplotypes detected in Alburnus species have indicated a consensus tree topology containing twenty lineages, each of corresponding to one species, and three Alburnus haplogroups corresponding to the geographical origins: Eastern Anatolia (I), Mediterranean (2) and Western & Northern Anatolia (3). The results indicate that the divergence between those haplogroups may have occurred during the Middle Miocene-Middle Pleistocene periods (from 14.9 to 5.29 million years).

摘要

在这项研究中，通过分析来自24个物种的112个种群的1172个样本的线粒体cyt b基因（1141 bp）和COI基因（1551 bp）序列，分析了土耳其淡水中的Alburnus属的系统发育。根据我们的发现，土耳其有20种有效物种，其中18种已经为人所知。虽然已经对6个Alburnus物种（A. battalgilae，A。istanbulensis，A。carinatus，A。schischkovi，A。nasreddini ve A. adanensis）进行了同步化处理，但来自Dicle河的两个新物种（Alburnus sp.1和Alburnus sp.2）和查普拉斯河/苏苏鲁克河已经确定。灭绝的物种，例如一。akili和A. nicaeensis没有观察到原位。在Alburnus物种中检测到的119个cyt b和80个COI单倍型的系统发育树拓扑和单倍型网络表明，共有树拓扑包含20个谱系，每个谱系对应一个物种，以及三个Alburnus单倍群，对应于地理起源：东安那托利亚（I ），地中海（2）和西部和北部安纳托利亚（3）。结果表明，这些单倍群之间的差异可能发生在中新世-中更新世时期（14.9至529万年）。
