^aThe diversity rank (1 most diverse to 14 least diverse) was calculated based on the ranking for the Shannon-Weaver, Simpson, and Fisher alpha indices

^bBeta diversity was calculated as β = S/α − 1 with α as the alpha diversity or richness per site and S as the total number of families in this soil collection calculated as Chao’s estimate (S = 39.37)
