Table 2: Partial pooling results showing variation of mycorrhizal type cover responses across regions: Region-specific coefficients for each type of mycorrhizal association: Arbuscular Mycorrhizas (AM), Ecto-Mycorrhizas (EcM), Ericoid Mycorrhizas (ErM) and Non-Mycorrhizal (NM) across all regions where a given mycorrhizal type was present. Explanatory variables were mean annual soil temperature (Temp), disturbance (Dist) as the three-level plot with 1: 52 to 102 m from the road, 2: 2 to 52 m from the road, and 3: 0 to 2 m from the road and the interaction between disturbance and temperature. Green and orange fields are respectively positive and negative correlations. Gray fields are factors that were not included in a given model following the results of model selection (see Table S1). Region abbreviations are as follows: ARC for Argentina, ARM for Armenia, AUN for Australia, CHE for Switzerland, CLC for Chile, CNN for China, TEN for Tenerife, IND for India, MTN for Montana, NOR for Norway and ORE for Oregon.
