性伴侣数量的差异（即，交配系统）有可能对生殖结构（如阴道）中存在的细菌群落产生强烈影响。由于这种结构作为配子的通道，存在于那里的细菌可能对宿主的繁殖成功有明显的直接影响。作为确定性行为与栖息在重要生殖结构上的潜在致病细菌群落之间关系的第一步，以及它们对健康的潜在影响，我试图量化一种滥交和一夫一妻制哺乳动物物种中细菌多样性的差异。为了实现这一点，我使用了两个同域物种的Peromyscusrodents-Peromyscus californicus和Peromyscus maniculatus，不同的方面，每个人的性伴侣的数量来测试的假设，即细菌多样性应该更大的滥交P。maniculatus相对于一夫一妻制P.加利福尼亚州。正如预测的那样，细菌多样性的遗传控制和操作分类单元为基础的指数表明，多样性更大的滥交物种。这些结果提供了重要的新的见解交配系统对自由生活的脊椎动物的细菌多样性的影响，并可能建议滥交的潜在成本。
Differences in the number of sexual partners (i.e., mating system) have the potential to exert a strong influence on the bacterial communities present in reproductive structures like the vagina. Because this structure serves as a conduit for gametes, bacteria present there may have a pronounced, direct effect on host reproductive success. As a first step towards the identification of the relationship between sexual behavior and potentially pathogenic bacterial communities inhabiting vital reproductive structures, as well as their potential effects on fitness, I sought to quantify differences in bacterial diversity in a promiscuous and monogamous mammal species. To accomplish this, I used two sympatric species ofPeromyscusrodents—Peromyscus californicusandPeromyscus maniculatusthat differ with regard to the number of sexual partners per individual to test the hypothesis that bacterial diversity should be greater in the promiscuousP. maniculatusrelative to the monogamousP. californicus. As predicted, phylogenetically controlled and operational taxonomic unit-based indices of bacterial diversity indicated that diversity is greater in the promiscuous species. These results provide important new insights into the effects of mating system on bacterial diversity in free-living vertebrates, and may suggest a potential cost of promiscuity.
