在两个群体的Euphydryas editha收集了8个世代的6个多态位点的等位基因频率估计。我们估计，此外，有效的人口规模为每一代的两个人口的结果标记重捕和其他领域的数据。随机遗传漂变所产生的等位基因频率的变化，然后使用计算机模拟和我们的有效人口规模的直接估计进行了研究。在一个群体中，三个位点（Got，Hk，Pgi）的观测值和计算机生成的预期值之间存在显著差异，假设仅漂移。这些观察结果与可变环境中的自然选择是一致的。
Estimates of allele frequencies at six polymorphic loci were collected over eight generations in two populations ofEuphydryas editha. We have estimated, in addition, the effective population size for each generation for both populations with results from mark-recapture and other field data. The variation in allele frequencies generated by random genetic drift was then studied using computer simulations and our direct estimates of effective population size. Substantial differences between observed values and computer-generated expected values assuming drift alone were found for three loci (Got, Hk, Pgi) in one population. These observations are consistent with natural selection in a variable environment.
