Here, we propose a hierarchy of ecological factors governing gut microbiota assembly, stability, and resilience. At the apex of this hierarchy is habitat filtering by host-derived electron acceptors, which dictates the ecological guilds that dominate distinct gut regions. Host dietary behavior shapes niche availability within these ecological guilds by regulating nutrient availability. Priority effects preserve taxonomic stability whereas microbial antagonism governs competition for open ecological positions. This framework highlights how host control over microbial energy metabolism directs microbiota self-assembly and maintains gut homeostasis.</p>","PeriodicalId":23275,"journal":{"name":"Trends in Microbiology","volume":" ","pages":""},"PeriodicalIF":14.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
