对具有有限扩散能力和存在于化石记录中的生物的研究，特别足以了解气候变化对物种分布和遗传结构的影响。Trochoidea geyeri （Soós 1926）是一种陆地蜗牛，仅在德国和法国的岛屿上零星分布。化石证据表明，在更新世更有利的气候时期，目前的盖耶氏T. geyeri种群是更广泛分布的遗迹。利用线粒体16S rDNA和核ITS-1序列变异的系统地理分析，推测了吉氏滴虫残余种群的历史。对这两个位点的巢式进化分析表明，该物种的起源在普罗旺斯，从那里它首先扩展到法国西南部，随后从那里扩展到德国。在末次冰期极大期（25-17 ka）之前估计的分化时间表明，目前物种范围北部的殖民化发生在更新世。我们得出的结论是，尽管个体积极避开不利条件的能力有限，但在过去的重大气候变化中，黄叶蝉可以相当成功地坚持在隐蔽的避难所中生存。
The study of organisms with restricted dispersal abilities and presence in the fossil record is particularly adequate to understand the impact of climate changes on the distribution and genetic structure of species. Trochoidea geyeri (Soós 1926) is a land snail restricted to a patchy, insular distribution in Germany and France. Fossil evidence suggests that current populations of T. geyeri are relicts of a much more widespread distribution during more favourable climatic periods in the Pleistocene. Phylogeographic analysis of the mitochondrial 16S rDNA and nuclear ITS-1 sequence variation was used to infer the history of the remnant populations of T. geyeri. Nested clade analysis for both loci suggested that the origin of the species is in the Provence from where it expanded its range first to Southwest France and subsequently from there to Germany. Estimated divergence times predating the last glacial maximum between 25–17 ka implied that the colonization of the northern part of the current species range occurred during the Pleistocene. We conclude that T. geyeri could quite successfully persist in cryptic refugia during major climatic changes in the past, despite of a restricted capacity of individuals to actively avoid unfavourable conditions.
