Abstract

The population genetic structure of two sympatric species of sigmodontine rodents (Oligoryzomys nigripes and Euryoryzomys russatus) was examined for mitochondrial DNA (mtDNA) sequence haplotypes of the control region. Samples were taken from three localities in the Atlantic Rain Forest in southern Brazil, along an altitudinal gradient with different types of habitat. In both species there was no genetic structure throughout their distribution, although levels of genetic variability and gene flow were high.

摘要

对巴西南部大西洋雨林三个地点的样本进行了研究，这些样本来自两种共生的沙鼠（黑足沙鼠和黄足沙鼠），研究了控制区的线粒体 DNA（mtDNA）序列单倍型。这些样本沿着海拔梯度分布，生境类型不同。在这两个物种中，尽管遗传变异和基因流水平很高，但它们的分布并没有表现出遗传结构。
