Figure 5.
The relative importance of space and the environment in structuring the arbuscular mycorrhizal (AM) fungal community composition in the roots (a) and the root‐associated soil (b) of Plantago lanceolata. All values are presented using the adjusted coefficient of determination (R 2 adjusted). The variation is partitioned into four fractions: purely environmental variation, purely spatial variation, both environmental and spatial variation, and unexplained variation (residuals). Asterisks indicate that a significant amount of variation is explained by the given fraction (***, P < 0.001).
