- Gut Microbiome of Two Rodent Species ( and ) from Two Regions Exhibit Different Structures and Assembly Mechanisms. Li, Haotian Gao, Qian Han, Jiawen Song, Qiuyue Yan, Fangheng Xu, Yunzhao Zhang, Chuansheng Wang, Xin Li, Yuchun The structure and assembly mechanism of wild animal gut microbiota represent persistent research hotspots. Among, the impact of geographic factors on the bacterial co-occurrence network characteristics and assembly mechanism of the gut microbiome remains unclear. Therefore, this study analyzed the gut microbiome of and from Anhui and Hubei provinces. The same alpha diversity pattern was found in the gut microbiome of species from the same region. The gut microbiome of the two rodent species in Anhui region exhibited "small world" characteristics, such as nodes with more local connections to allow interaction information (such as metabolites) to rapidly spread throughout the entire microbial community. In addition, dispersal limitations and heterogeneous selection accounted for higher proportions of the gut microbiome in the rodents from the Anhui and Hubei regions, respectively. The higher proportion of heterogeneous selection may exacerbate selection pressure in the Hubei region. Multiple regression on distance matrices analysis revealed that geographic region exerted a limited but significant influence (0 < R < 0.2, * < 0.05) on the gut microbiome, surpassing the effects of host phylogeny, gender, and weight. Nevertheless, the roles of regional factors-such as environmental microbes, pollutants, and diet-remain unexamined, and their potential as key drivers of microbiota variation in these rodents warrants further investigation.
