The eastern-Mediterranean taxa, which include both widely distributed species and taxa with minuscule ranges, represent a good model to study the impacts of range size and fragmentation on the levels of genetic diversity and differentiation. To assess the patterns of genetic diversity and phylogenetic relationships among eastern-Mediterranean taxa, genetic variation was assessed by eight nuclear microsatellite loci in 52 populations of taxa with a focus on those distributed in Turkey and the Caucasus. Both at the population and the taxon level, the subspecies or regional populations of s.l. exhibited generally higher allelic richness, private allelic richness, and expected heterozygosity compared with s.l. Results of both the structure analysis and distance-based approaches showed a strong differentiation of the two subspecies from the rest as well as from each other, whereas the subspecies of were distinct but less differentiated. ABC simulations were run for a set of scenarios of phylogeny and past demographic changes. For . × the simulation gave a poor support for the hypothesis of being a taxon resulting from a past hybridization, the same is true for : both they represent evolutionary branches of .
东地中海分类群，包括分布广泛的物种和分布范围极小的分类群，是研究分布范围大小和破碎化对遗传多样性和分化水平影响的良好模型。为了评估东地中海分类群之间的遗传多样性模式和系统发育关系，我们通过八个核微卫星位点对52个分类群种群的遗传变异进行了评估，重点关注分布在土耳其和高加索地区的分类群。无论是在种群水平还是分类群水平上，广义的某分类群的亚种或区域种群相比狭义的该分类群通常表现出更高的等位基因丰富度、私有等位基因丰富度和预期杂合度。结构分析和基于距离方法的结果均表明，该分类群的两个亚种与其他分类群以及彼此之间都存在强烈分化，而另一分类群的亚种虽明显但分化程度较低。针对一系列系统发育和过去人口统计学变化的情景进行了近似贝叶斯计算（ABC）模拟。对于某杂交组合，模拟结果对其是过去杂交产生的分类群这一假设支持度很低，另一杂交组合情况相同：它们均代表该分类群的进化分支。
