Table 1 The eight categorical predictor variables that were explored in our random-effects meta-analyses

From: Home-field advantage? evidence of local adaptation among plants, soil, and arbuscular mycorrhizal fungi through meta-analysis

Name Levels
Origin* 5 ‘Sympatric’ (all components are from the same geographic location), ‘Allopatric’ (all components are from different geographic locations), ‘Fungi-Soil Sympatric’ (fungus and soil sympatric but allopatric to the plant), Plant-Fungi Sympatric (plant and fungus sympatric but allopatric to the soil), Plant-Soil Sympatric (plant and soil sympatric but allopatric to the fungus)
Plant Functional Group 6 C4 grasses, C3 grasses, N-fixing forbs, non-N-fixing forbs, N-fixing woody plants, non-N-fixing woody plants
Inoculum Complexity 3 Whole soil inoculum, multiple species inoculum, single species inoculum
Sterility 2 Sterilized (background soil was sterilized prior to the experiment), not sterilized
Microbe Control 3 Microbial wash (application of aqueous filtrate of non-mycorrhizal microbes), other microbial addition (non-mycorrhizal microbes added via other avenues such as rhizosphere soil from non-mycorrhizal culture plants), no added non-mycorrhizal microbes
Experimental set-up: 2 Laboratory (greenhouse, growth chamber, lathe house or shade house), field
2 Fertilized or not
  1. Seven variables were used previously in Hoeksema et al. [23] and one variable was unique to our analyses (as indicated by asterisk)
