Habitat filtering more than microbiota origin controls microbiome transplant outcomes in soil.

ABSTRACT: Human activities cause a global loss of soil microbiome diversity and functionality. One way to reverse this trend is through microbiota transplants, but the processes determining merger outcomes are not well understood. Here, we investigated the roles of habitat filtering and microbiota origin on microbiome development upon mergers, with the hypothesis that native strains are better adapted to their own habitat and will outcompete non-native ones in niche colonization. To test this, we contrasted community development in soil microcosms between two taxa-diverse microbiota originating from either topsoil [SoilCom (SC)] or freshwater lake [LakeCom (LC)], and a defined mixture of 21 soil bacteria (SynCom). When inoculated separately, SC and LC showed similar taxa and colonization patterns co
