Figure S7. Winner prevalence estimates in simulated groups at uniform abundance. Abundances have been simulated using a Poisson distribution assuming that OTUs are at a variable minimum abundance threshold (x-axis). If abundance estimates were perfect, we would expect a winner prevalence of zero, but noise associated with the sampling processes creates artificial winners. The dashed red line is the minimum abundance threshold used in our study. (PDF 18 kb)
