Yang, Xinyuan Gao, Shuxuan Kong, Xiangxian Gao, Fei Xu, Qiang Animals Gastrointestinal Microbiome Geologic Sediments RNA, Ribosomal, 16S Bacteria Sea Cucumbers Ecosystem Phylogeny Gut microbiomes play critical roles in host physiology and ecological contributions of sea cucumbers in tropical coral reefs. However, the relative importance of host filtering versus environmental factors in gut microbiome assembly remains poorly quantified in natural populations. Using 16S rRNA gene amplicon sequencing and sediment physicochemical analyses, this study characterized gut microbiomes of three co-occurring sea cucumber species (Holothuria atra, Holothuria edulis and Stichopus chloronotus) across heterogeneous habitats. Despite significant spatial variation in sediment properties and microbial communities, all three sea cucumber species maintained species-specific and stable gut microbiomes across sites. Although source tracking identified sediment as the primary microbial reservoir, variation partitioning revealed that host filtering far overrode environmental heterogeneity, with sediment physicochemical properties explaining a negligible fraction ( |
