Relationship between the phylogenetically weighted taxa composition of plant and arbuscular mycorrhizal fungi (AMF) across vegetation patches. The phylogenetic composition of plants and AMF in each patch is characterized as the first principal component of the P matrix described by Pillar and Duarte (2010). Plant and AMF PC1 represent the phylogenetic composition of the assemblages of the plant and AMF, respectively. Extreme values of the plant PC1 correspond to patches in which either nurse (high negative loading values) or facilitated (high positive loading values) species predominate. Extreme values of the AMF PC1 correspond to patches with low and high AMF phylogenetic diversity.
