The recent invasion of the lionfish Pterois miles to the Mediterranean draws major concerns to the fate of the indigenous ecosystem, based on previous knowledge of the species' detrimental capabilities as an introduced species in the Western Atlantic Ocean. In order to determine invasive patterns in the Eastern Mediterranean, we compared the genetic divergence of two mtDNA markers, the COI and D-loop, between and within the introduced Levantine and native range Red Sea populations of the lionfish. COI region presented a remarkably shallow genealogy, and both genes have failed to show a definite geographic population structure, with non-significant AMOVA and low pairwise F values. A shared haplotype across all localities in the D-loop provided probable confirmation for the Red Sea origin of the invasive population, and a number of introduced haplotypes indicated that the Mediterranean populations are a product of multiple invasion events. Finally, we observed large haplotype diversity in the Red Sea samples that were absent from the introduced localities, implying a possible future enforcement to the invasive genetic pool in the Mediterranean Sea.
基于之前对狮鱼作为西大西洋外来物种的有害能力的了解，近期狮鱼（细纹狮子鱼）入侵地中海引发了人们对当地生态系统命运的重大担忧。为了确定东地中海的入侵模式，我们比较了引入的黎凡特种群和红海本地种群之间以及内部的两个线粒体DNA标记（COI和D-loop）的遗传差异。COI区域呈现出非常浅的谱系，并且两个基因均未显示出明确的地理种群结构，方差分析（AMOVA）不显著且成对F值较低。D-loop中所有地点共享的单倍型可能证实了入侵种群起源于红海，并且一些引入的单倍型表明地中海种群是多次入侵事件的产物。最后，我们观察到红海样本中存在引入地点所没有的单倍型多样性，这意味着未来地中海入侵基因库可能会进一步扩大。
