Linear regression between phylogenetic diversity and phylogenetic composition of arbuscular mycorrhizal fungi (AMF) assemblages (i.e. patches). Phylogenetic diversity is measured as mean phylogenetic distance between each pairwise AMF DNA sequence present in each patch. Phylogenetic composition in each patch is characterized as the first principal component of the P matrix described by Pillar and Duarte (2010) which represents the phylogenetically weighted taxa composition of each vegetation patch.
