Calculations for rarefraction curves, the estimated maximum number of OTUs, Shannon-wiener index and chaoI index were performed using QIIME version 1.
Rarefraction estimates of richness are based on a distribution free method using the following equation:
Many different cosmological scenarios are listed there, including such exotics as the transits through the states of infinite rarefraction and infinite density on a finite volume (that is possible under special physical conditions).
