The Slovenian False Ringlet Coenonympha oedippus populations are under serious threat, as in the last two decades have witnessed a sharp decline in population distribution and size due to destruction, fragmentation and/or habitat quality degradation through intensive agriculture, abandonment of use and urbanization. We investigated the genetic diversity and structure of C. oedippus from the entire range of the species in Slovenia. Our results showed that the genetic variation in the Slovenian C. oedippus populations agrees with the geographical structure and the ecotypes previously determined by morphological and ecological data. We confirmed the existence of four genetically divergent and spatially non-overlapping geographical groups (Istria, Karst, Gorica, Ljubljansko barje) and two ecotypes ("wet" and "dry"). Despite small sample sizes due to critically threatened species, the results indicated significant nuclear and mitochondrial genetic diversity within the spatial groups. By gaining new insights into the evolutionary history of the C. oedippus population, we have recommended to consider the Slovenian population as one Evolutionary Significant Unit, and four spatial populations as Management Units for conservation purposes.

高度濒危蝴蝶 Coenonympha oedippus (Nymphalidae: Satyrinae) 在其分布南部边缘的种群遗传结构

斯洛文尼亚 False Ringlet Coenonympha oedippus 种群正受到严重威胁，因为在过去的二十年中，由于集约化农业、放弃使用和城市化造成的破坏、破碎和/或栖息地质量下降，种群分布和规模急剧下降。我们调查了斯洛文尼亚整个物种范围内的 C. oedippus 的遗传多样性和结构。我们的结果表明，斯洛文尼亚 C. oedippus 种群的遗传变异与先前由形态和生态数据确定的地理结构和生态型一致。我们确认存在四个遗传上不同且空间上不重叠的地理群体（伊斯特拉、喀斯特、戈里察、卢布尔雅那巴耶）和两种生态型（“湿”和“干”）。尽管由于受到严重威胁的物种而样本量很小，但结果表明空间组内具有显着的核和线粒体遗传多样性。通过对 C. oedippus 种群进化历史的新见解，我们建议将斯洛文尼亚种群视为一个进化重要单位，将四个空间种群作为保护目的的管理单位。
