摘要

The clausiliid Carinigera buresi has a distribution that, considering its low vagility, is enigmatically disjunct. Carinigera buresi pharsalica occurs in Thessaly in central Greece, over 200 km outside the main range of C. buresi in NE Greece - SW Bulgaria. This range disjunction has led to the hypothesis that in antiquity the ancestors of C. buresi pharsalica were transported by the marble trade from NE Greece to Thessaly. To explore this hypothesis, we included samples from the NE Greek island of Thasos (the only area within the range of C. buresi from which marble was widely transported in antiquity) in a time-calibrated molecular phylogeny of C. buresi. Maximum likelihood (GARLI) and time-calibrated Bayesian (BEAST) analyses of mitochondrial cytochrome c oxidase subunit I (COI) from samples collected throughout the range of C. buresi indicate that the ancestral C. buresi pharsalica COI lineage reached Thessaly not from Thasos, but from the NE Greek mainland. This happened between 1,740 and 83,000 yr BP according to the BEAST analyses. Although this time interval does not entirely pre-date the earliest phase of marble transport in the region, we consider this mode of dispersal unlikely for two reasons: (1) our data show that C. buresi pharsalica must be older than estimated on the basis of geological calibration points; (2) our findings indicate that the dispersal event that brought C. buresi pharsalica to Thessaly did not follow ancient marble transport routes. We suggest dispersal via floating objects or aerial dispersal by birds as alternative hypotheses to dispersal by the historic marble trade. Unexpectedly, our phylogenetic analyses also showed the COI haplotype of C. buresi from the city of Kavala to be nested among COI haplotypes from northern Thasos. This suggests possible human-aided dispersal of C. buresi from Thasos to Kavala.

Buresi Pharsalica的祖先，由来自Ne希腊的大理石交易到蛹的祖先。为了探索这一假设，我们包括来自Thaso的NE希腊岛的样本（在大理石的C. Buresi范围内的唯一区域在古代广泛地在古物中被广泛运输的区域）。在整个C. Buresi的样品中测量线粒体细胞色素C氧化酶I（COI）的最大可能性（GARLI）和时间校准的贝叶斯（BEAST）分析，表明祖先的C. BULESI Pharsalica Coi谱系达到Thessaly而不是来自萨索斯，但是来自NE希腊大陆。根据野兽分析，这发生在1,740和83,000岁之间。虽然这一时间间隔并不完全预先追溯到该地区的最早的大理石运输阶段，但我们认为这种模式的分散模式不太可能有两个原因：（1）我们的数据显示，C. Buresi Pharsalica必须比基于估计估计地质校准点; （2）我们的调查结果表明，将C. Buresi Pharsalica带到Thessaly的分散事件并未跟随古老的大理石运输路线。我们建议通过鸟类的浮动物体或空中分散作为历史大理石交易作为替代假设的替代假设。出乎意料的是，我们的系统发育分析还显示了来自卡瓦拉市的C. Buresi的Coi单倍型嵌套在北北部的Coi单倍型中。这表明来自塔斯氏毒剂的C. Buresi可能的人援助散发出Kavala。
