微卫星标记首先用于将来自多瑙河、莱茵河和美因河以及易北河排水系统的欧洲河鳟 Thymallus thymallus 个体划分为亚群，并估计过去几代的个体移民血统。随后，研究人群被从新移民中“清除”，并通过应用线粒体DNA标记重新估计“清除”人群中进化谱系的比例。结果证实，在排水系统接触区采样的种群中存在高水平的不同 mtDNA 谱系混合（即自然二次接触）。此外，在已知受到来自不同来源的欧洲河鳟放养影响的几个种群中观察到大量的基因渗入。
Microsatellite markers were first used to partition individuals of European grayling Thymallus thymallus, from the Danube, Rhine and Main, and Elbe drainage systems into subpopulations and to estimate individual immigrant ancestries over the last few generations. Subsequently, the studied populations were 'purged' from recent immigrants and the proportions of evolutionary lineages within the 'purged' populations were re-estimated by applying mtDNA markers. The results confirmed a high level of admixture of the divergent mtDNA lineages (i.e. natural secondary contact) in populations sampled at the contact zones of the drainages. In addition, a substantial amount of introgression was observed for several populations that were known to be affected by stocking of European grayling from different origins.
