Supplement 1. Information on the studies in the metadata sets and the Visual Basic code associated with the rarefactions.

Data1.txt is a tab-delimited ASCII file. The file contains references, taxa, crops, countries, taxonomic groups, id levels, and abundance, richness, and evenness values for each study in the metadata set comparing organic and conventional farming.

Column definitions follow:

1 = REFERENCE
2 = TAXA
3 = CROP(S)
4 = COUNTRY
5 = TAXONOMIC GROUP
6 = ID LEVEL
7 = ABUNDANCE IN CONVENTIONAL
8 = ABUNDANCE IN ORGANIC
9 = ABUNDANCE EFFECT SIZE
10 = RICHNESS OBSERVED IN CONVENTIONAL
11 = RICHNESS OBSERVED IN ORGANIC
12 = OBSERVED RICHNESS EFFECT SIZE
13 = EVENNESS OBSERVED IN CONVENTIONAL
14 = EVENNESS OBSERVED IN ORGANIC
15 = OBSERVED EVENNESS EFFECT SIZE
16 = RICHNESS RAREFIED IN CONVENTIONAL
17 = RICHNESS RAREFIED IN ORGANIC
18 = RAREFIED RICHNESS EFFECT SIZE
19 = EVENNESS RAREFIED IN CONVENTIONAL
20 = EVENNESS RAREFIED IN ORGANIC
21 = RAREFIED EVENNESS EFFECT SIZE
