摘要1.利用等位酶和细胞色素氧化酶I基因片段研究了蜉蝣Bungona narilla的遗传结构。2.这项研究有两个主要目的。第一个是确定线粒体DNA的遗传变异模式是否与以前发现的等位酶相似，即在单一溪流内的游泳池之间的变异比溪流之间的变异更明显。线粒体DNA结果与先前报道的等位酶相似，支持任何特定池内的幼虫不代表总人口的想法，并可能导致一些交配。3.第二个目的是检验这一假设，即在一个流池之间的变化是更大的干期后比湿期后。这是因为在潮湿期后，幼虫会有更大的机会混合，因为游泳池之间的运动。这一假设部分支持的线粒体DNA数据，但不是由等位酶数据，其中池之间的变化是非常低的两个采样场合。造成这种差异的原因尚不清楚。
SUMMARY 1. Genetic structure of the mayfly Bungona narilla was examined using allozymes and a section of the cytochrome oxidase I gene. 2. The study had two major aims. The first was to determine whether patterns of genetic variation in mitochondrial DNA were similar to those found previously for allozymes, i.e. that more variation was evident among pools within a single stream than among streams. The mitochondrial DNA results were similar to those reported previously for allozymes, supporting the idea that larvae within any particular pool were unrepresentative of the total population and may result from a few matings. 3. The second aim was to test the hypothesis that the variation among pools within a stream was greater after dry periods than after wet periods. This was because after wet periods, larvae would have greater opportunity for mixing because of movement among pools. This hypothesis was partly supported by the mitochondrial DNA data but not by the allozyme data, in which variation among pools was extremely low on both sampling occasions. The reasons for this difference are unclear.
