Different ecological processes contributed to the observed beta diversity depending on the stage of community succession and faction of the microbiome (bacteria or Eukarya). a The successful immigration of taxa over time as estimated by introduction of new OTUs. b, c Binary Jaccard distance between samples, partitioned by contributions from nestedness (species loss) and turnover (species replacement). Lighter colors represent samples that have few OTUs in common, highlighting changes in community structure over time. The total change (βjac) is the sum of changes due to nestedness (βjne) and turnover (βjtu). d Inferred changes in degree to which variable selection (βNTI > +2), stochastic processes (−2 < βNTI < +2) and homogenous selection (βNTI < −2) contribute to different factions of the community (bacteria and Eukarya) at each observed stage of succession
