Abstract

Laboratory populations of Drosophila melanogaster were subjected to heat and cold shock of sufficient duration and intensity to cause about 90 percent mortality. Alcohol dehydrogenase phenotypes were determined in survivors and controls. Significant changes in phenotypic frequencies occurred as a result of both treatments such that relative fitness appeared to be dependent on temperature. The alcohol dehydrogenase phenotype most frequently surviving heat under laboratory conditions is the same phenotype as that previously found to be higher in frequency in natural populations in areas with higher average temperature.

摘要

对黑腹果蝇的实验室种群施加了持续时间和强度足够的热休克和冷休克,以导致约90%的死亡率。在幸存者和对照组中测定了乙醇脱氢酶表型。两种处理均导致表型频率发生显著变化,因此相对适合度似乎取决于温度。在实验室条件下最常从热休克中存活下来的乙醇脱氢酶表型,与先前发现在平均温度较高地区的自然种群中频率较高的表型相同。
