肠道微生物群对其宿主起着至关重要的作用。花齿龙蜥具有显著的两性异形和雄性三态性，这为研究其肠道菌群提供了一个有趣的系统。我们比较了两种性别之间以及三种雄性O. fallaciosa。雌雄间肠道细菌群落结构存在显著差异。相对于男性，女性与更高的细菌α多样性相关。大型雄性具有较高的厚壁菌门相对丰度和厚壁菌门/拟杆菌（F/B）比，这有助于营养效率。这些结果加深了我们对O. fallaciosa在两性之间和三种雄性变型之间的差异，揭示了锹形虫肠道菌群、营养水平和表型进化之间的关系。黄齿锹甲（Odontolabis fallaciosa）是一种体型巨大的锹甲，雌雄异形，雌雄异形。然而，人们对它们的肠道微生物群知之甚少，而肠道微生物群可能在塑造宿主健康方面发挥着不可或缺的作用。本研究的目的是研究两性间和三种雄性O.使用高通量测序（Illumina MiSeq）从中国获得fallaciosa。雄性和雌性之间肠道细菌群落结构存在显著差异，表明性别似乎是塑造肠道细菌群落的关键因素。女性比男性有更高的细菌α多样性。三种雄性变体的肠道细菌群落结构差异不大。然而，与中型和小型雄性相比，大型个体与厚壁菌门和厚壁菌门/拟杆菌（F/B）比率的相对丰度较高相关，这可能有助于营养效率。总之，这些结果可能有助于我们进一步了解甲虫-细菌相互作用的O。两个人之间，两个人之间，三个人之间。
Intestinal microbiota play crucial roles for their hosts. Odontolabis fallaciosa shows striking sexual dimorphism and male trimorphism, which represents an interesting system to study their gut microbiota. We have compared the intestinal bacterial community structure between the two sexes and among three male morphs of O. fallaciosa. The gut bacterial community structure was significantly different between males and females. The females were associated with higher bacterial alpha-diversity relative to males. Large males had a higher relative abundance of Firmicutes and Firmicutes/Bacteroides (F/B) ratio, which contributed to nutritional efficiency. The results increased our understanding of beetle–bacterial interactions of O. fallaciosa between the two sexes, and among three male morphs, which might reveal the relationship among the gut microbiota, nutrition level, and phenotypic evolution of the stag beetle. Odontolabis fallaciosa (Coleoptera: Lucanidae) is a giant and popular stag beetle with striking sexual dimorphism and male trimorphism. However, little is known about their intestinal microbiota, which might play an indispensable role in shaping the health of their hosts. The aim of this study was to investigate the intestinal bacterial community structure between the two sexes and among three male morphs of O. fallaciosa from China using high-throughput sequencing (Illumina MiSeq). The gut bacterial community structure was significantly different between males and females, suggesting that sex appeared to be the crucial factor shaping the intestinal bacterial community. Females had higher bacterial alpha-diversity than males. There was little difference in gut bacterial community structure among the three male morphs. However, compared to medium and small males, large individuals were associated with the higher relative abundance of Firmicutes and Firmicutes/Bacteroides (F/B) ratio, which might contribute to nutritional efficiency. Overall, these results might help to further our understanding of beetle–bacterial interactions of O. fallaciosa between the two sexes, and among the three male morphs.
