*a*Libraries were constructed from unimproved (SAF,*n*= 138 sequences) and improved (SL,*n*= 137) Scottish soils and libraries constructed using soils collected in 1997 (*n*= 139) and 2000 (*n*= 129) from a Wisconsin agricultural soil. Comparisons were made using the integral form of the Cramér-von Mises statistic as implemented in ∫-LIBSHUFF with 10,000 randomizations and an upper integration bound of infinity. The margin of error for the*P*value's 95% confidence interval for the*P*values near 0.05 was 0.004.
