Inoculation Complexity for Within Paper Analyses: When a single species of fungi was used as inocula, the effect of sympatry was greater than allopatry (although not different than zero) while the reverse was true when the fungal inocula contained multiple species. Values shown represent the ratio of weighted mean effect sizes (ES) ± standard error for arbuscular mycorrhiza from within paper examinations of Plant and Fungi (a) and Fungi and Soil (b). The dotted line indicates no response, values above the line indicate positive local adaptation, and values below the line indicate maladaptation. P values indicate differences based on planned contrasts
