Summary Gut microbiota typically occupy habitats with definable limits/borders that are comparable to oceanic islands. The gut therefore can be regarded as an ‘island’ for the assembly of microbial communities within ‘sea’ surrounding environments. This study aims reveal ecological mechanisms govern in fish ecosystem. Taxonomic compositions, phylogenetic diversity, and community turnover across host development were analyzed via high‐throughput sequencing 16S rRNA gene amplicons. results indicate Shannon diversity three examined freshwater species all significantly decreased development, dominant bacterial taxa also changed during development. Null model phylogenetic‐based mean nearest taxon distance (MNTD) analyses suggest environmental filtering led ‘island’. However, clustering local deterministic processes governed became less distinct developed. observed shaped seemed mainly by environment some other selective changes accompanying process. These findings greatly enhance our understanding stage‐specific patterns

Abstract Community assembly of crop-associated fungi is thought to be strongly influenced by deterministic selection exerted the plant host, rather than stochastic processes. Here we use a simple, sorghum system with abundant sampling show that forces (drift or dispersal) act on fungal community in leaves and roots early host development when drought stressed, conditions mycobiomes are small. Unexpectedly, find no signal for stochasticity stress relieved, likely due renewed host. In our experimental system, compartment exerts strongest effects mycobiome assembly, followed timing lastly genotype. Using dissimilarity-overlap approach, universality different compartments functional guilds fungi.
