Here,we show that while mitochondrial lineages remain completely distinct on both sides of the Atlantic,limited hybridization is detectable with nuclear DNA markers.The nuclear hybridization signal peaks in the northern areas and decreases towards the southern range limits on both continents according to Bayesian assignment analyses.By simulating increasing proportions of both F1 hybrids and admixed individuals from the southern to the northern-most locations,we were able to generate highly significant isolation by distance patterns in both cases,reminiscent of previously published data for the European eel.Finally,fitting an isolation-with-migration model to our data supports the hypothesis of recent asymmetric introgression and refutes the alternative hypothesis of ancient polymorphism.

至今为止,大西洋两岸的线粒体体系有绝对差异,但也有一定数量的杂交可以通过核DNA标记被检测到.细胞核杂交标记在北部地区很常见,但根据贝叶斯任务分析法,在南部地区的两部分大陆上这一标记的出现率都减少了.通过模拟F...
