Experimental design.

Soil biodiversity	GCFs (no.)	Replicates (no.)
High/low	0	10
High/low	1	10
High/low	2	15
High/low	4	15
High/low	6	15
High/low	8	15
High/low	10	15

Note: there were 10 repeats for each single global change factor (GCF); total experimental units = (10 + 10 × 10 + 15 × 5) × 2 = 370; for the GCF levels from 2 to 10, random draws were conducted to select GCFs for each replicate.
