研究了酶基因座的遗传变异与环境变异的关系，以阐明自然选择在进化中的作用。葡萄酒厂内未强化葡萄酒渗出液中果蝇繁殖地的乙醇水平与许多腐烂的水果和蔬菜中的乙醇水平相似。葡萄酒厂内的强化葡萄酒渗出物的乙醇含量平均是其他育种地点的3倍。没有证据表明乙醇水平的这种变化与D.黑腹果蝇在葡萄酒厂内或葡萄酒厂外的地点。D. simulans在酿酒厂内部的站点比外部站点的频率低，尽管这种差异可能与乙醇水平无关。适应自然水平的环境乙醇的D。黑腹菌不一定改变Adh频率。
The relationship between genetic variation at loci encoding enzymes and environmental variation was studied to elucidate the role of natural selection in evolution. Ethanol levels in Drosophila breeding sites in seepages of unfortified wine inside wineries were similar to those in many decaying fruits and vegetables. Fortified wine seepages inside wineries have ethanol levels on average 3 times as high as other breeding sites. There was no evidence that this variation in ethanol levels was associated with differences in AdhF [alcohol dehydrogenase] frequencies in D. melanogaster at sites either within wineries or outside wineries. D. simulans was at lower frequencies at sites inside wineries compared to sites outside although this differences may not be related to ethanol levels. Adaptation to natural levels of environmental ethanol by D. melanogaster does not necessarily modify Adh frequencies.
