Neutral partitioning analysis from the Sloan neutral model for each fly species (D. bivittatus, D. ciliatus, Z. cucurbitae).

UW stands for unweighted partitioning and AW stands for abundance-weighted partitioning. The neutral columns show the percentage of ASVs in the microbiome with an mean abundance-prevalence ratio that fits the expectation of the neutral assembly model (within 95% confidence interval). The below columns show the percentage of ASVs that have a lower prevalence than expected for their mean abundance predicted by the neutral model. The above columns show the percentages of ASVs that have a higher prevalence than expected for their mean abundance predicted by the neutral model. m gives the mean migration rate of all ASVs associated with a fly species.
