复杂的肠道细菌群落对生物体健康有重大影响。然而，栖息地变化对野生鸟类肠道微生物群的影响的知识是有限的。在这项研究中，我们对银耳梅西亚（Leiothrix argentauris）的两个不同亚种、本土亚种（L. a. rubrogularis）和移民亚种（L. a. vernayi），使用16S rRNA基因高通量测序。这两个亚种生活在痕量金属污染区，L。a. vernayi是被贩卖的。它们是研究野生动物迁移到新栖息地时肠道微生物组如何变化的绝佳系统。我们假设，移民亚种将发展相同的适应作为本地亚种在应对栖息地的变化。结果表明，在相似影响因素的共同作用下，本地亚种和外来亚种的肠道菌群组成、多样性和功能代谢均无显著差异（所有方差分析的p值均>0.05）。此外，两个亚种的肠道菌群组成和功能代谢表现出对微量金属损伤的适应性。线性判别分析效应量（LEfSe）分析显示，移民亚种肠道菌群中的Massilia显著高于本地亚种，表明移民亚种遭受了生境变化。最后，我们发现生活在矿区的这两个亚种在其肠道微生物群中的致病菌比例极高（约90%），远高于生活在野生环境中的其他物种（约50%）。研究结果揭示了移民银耳梅西亚斯肠道菌群对重金属胁迫的适应性，为矿区生物多样性保护和污染治理提供指导。
The complex gut bacterial communities have a major impact on organismal health. However, knowledge of the effects of habitat change on the gut microbiota of wild birds is limited. In this study, we characterized the gut microbiota of two different subspecies of the Silver-eared Mesia (Leiothrix argentauris), the native subspecies (L. a. rubrogularis) and immigrant subspecies (L. a. vernayi), using 16S rRNA gene high-throughput sequencing. These two subspecies live in a trace metal-contaminated area, and L. a. vernayi was trafficked. They are an excellent system for studying how the gut microbiome of wild animal changes when they move to new habitats. We hypothesized that the immigrant subspecies would develop the same adaptations as the native subspecies in response to habitat changes. The results showed that there were no significant differences in the composition, diversity, or functional metabolism of gut microbiota between native and immigrant subspecies under the combined action of similar influencing factors (the p values of all analyses of variance >0.05). In addition, the composition and functional metabolism of gut microbiota in two subspecies showed adaptation against trace metal damage. Linear discriminant analysis effect size (LEfSe) analysis revealed that Massilia in the intestinal microbiota of immigrant subspecies was significantly higher than that of native subspecies, suggesting that immigrant subspecies suffered habitat change. Finally, we found that these two subspecies living in the mining area had an extremely high proportion of pathogenic bacteria in their gut microbiota (about 90%), much higher than in other species (about 50%) living in wild environment. Our results revealed the adaptation of intestinal microbiota of immigrant Silver-eared Mesias under heavy metals stress, which would provide guidance for biodiversity conservation and pollution management in mining area.
