Abstract

We examined the association between body mass and metabolic rate in Drosophila melanogaster under a variety of conditions. These included comparisons of body mass and metabolic rate in flies from different laboratory lines measured at different ages, over different metabolic sampling periods, and comparisons using wet versus dry mass data. In addition, the relationship between body mass and metabolic rate was determined for flies recently collected from wild populations. In no case was there a significant correlation between body mass and metabolic rate. These results indicate that care must be taken when attempting to account for the effects of body mass on metabolic rate. Expressing such data in mass-specific units may be an inappropriate method of attempting to control for the effects of differences in body mass.

摘要

我们在多种条件下研究了黑腹果蝇的体重与代谢率之间的关联。这些条件包括比较不同实验室品系的果蝇在不同年龄、不同代谢采样时间段所测得的体重和代谢率，以及使用湿重与干重数据进行比较。此外，还测定了从野生种群中刚采集的果蝇的体重与代谢率之间的关系。在任何情况下，体重与代谢率之间均无显著相关性。这些结果表明，在试图解释体重对代谢率的影响时必须谨慎。以单位体重为基础来表示此类数据可能是一种不合适的方法，无法用来控制体重差异所产生的影响。
