Parsimonious variables and their explaining power (adjusted R²) of RDA on soil eukaryotic microbe community composition along an elevation gradient on Mt. Asahi, Hokkaido, Japan, using different sampling strategies

Strategy	Best predicting variables	Frequency	Adjusted R2
Replicate	OM_pc1 + elevation + pH + C/N	1	0.254
Transect	OM_pc1 + elevation + N/P	568	0.242
	OM_pc1 + elevation	253	0.210
	OM_pc1 + pH	108	0.203
	OM_pc1 + pH + N/P	33	0.250
	OM_pc1 + pH + P	19	0.245
	OM_pc1 + elevation + P	14	0.236
	OM_pc1 + elevation + pH	3	0.238
	OM_pc1 + elevation + N/P + pH	2	0.272

For the transect strategy, the results of 1000 datasets are shown in descending order based of the frequency of the combination of parsimonious variables
