Abstract

The natural habitat of Qatar lacks permanent surface freshwater. Temporary ponds formed after heavy rains in the winter season are inhabited by the tadpole shrimp Triops granarius (Branchiopoda: Notostraca). In order to assess the molecular diversity of this species and to determine the relationship of Qatari populations with those from other regions, the sequences of 28S rRNA, 16S rRNA, and COI genes of individuals collected in five temporary pools were examined. Maximum likelihood phylogenetic analysis showed a high level of sequence uniformity at all three loci and indicates that the closest relatives of T. granarius in Qatar are from south Ural and northeastern Asia, including Mongolia, China, and Japan. This pattern is consistent with the geological evidence that T. granarius expanded more recently from North Africa to northeastern Asia through the Arabian land bridge. Lastly, the large genetic gap existing between the Qatar populations and their closest relatives supports the recognition of a new lineage.

卡塔尔蝌蚪虾Triops granarius的遗传多样性、系统发育和生物地理学

卡塔尔的自然栖息地缺乏永久的地表淡水。冬季大雨后形成的临时池塘栖息着蝌蚪虾Triops granarius(鳃足纲:Notostraca)。为了评估该物种的分子多样性，并确定卡塔尔种群与其他地区种群的关系，对5个临时库中收集的个体的28S rRNA、16S rRNA和COI基因序列进行了检测。最大似然系统发育分析显示，这3个位点的序列高度一致，表明卡塔尔的赤鼠最近的亲缘来自乌拉尔南部和东北亚，包括蒙古、中国和日本。这种模式与地质证据相一致，即T. granarius最近通过阿拉伯大陆桥从北非扩展到东北亚。最后，卡塔尔人与其近亲之间存在的巨大遗传差距支持了对新世系的认识。

期刊介绍： Zoology in the Middle East is a journal which publishes original papers and review papers on ecology, zoogeography, animal biology, biodiversity, faunistics, systematics and morphology of the Middle East. It seeks to further the understanding of the Middle East as a zoogeographic unit and aims at improving the interchange of knowledge and ideas between specialists on different subjects and taxa.
