We present preliminary data on mitochondrial DNA diversity within and among populations of the ants Lasius niger and Lasius platythorax in Poland. Phylogenetic analysis based on the mitochondrial DNA markers: cytochrome c oxidase subunit I (cox1) and 16S ribosomal RNA (16S rRNA) confirms the species status of L. niger and L. platythorax. Intraspecific variability is low in both species, which might be a result of severe bottlenecks and rapid postglacial expansion into Central Europe.

波兰同胞蚂蚁种群的低遗传多样性：Lasius niger (L.) 和 Lasius platythorax Seifert (膜翅目，蚁科)

我们提供了波兰 Lasius niger 和 Lasius platythorax 蚂蚁种群内部和之间线粒体 DNA 多样性的初步数据。基于线粒体 DNA 标记物的系统发育分析：细胞色素 c 氧化酶亚基 I (cox1) 和 16S 核糖体 RNA (16S rRNA) 证实了黑喉乳杆菌和阔胸乳杆菌的物种状态。两种物种的种内变异都很低，这可能是严重瓶颈和冰后迅速扩张到中欧的结果。
