From: Adaptive matching between phyllosphere bacteria and their tree hosts in a neotropical forest
Principal components analysis (PCA) of microbial functional composition from the phyllosphere of neotropical trees. The 20 Tier 3 functions contributing the most to variation among samples are indicated as black arrow. Plant traits were fitted onto the PCA in a configuration that would maximize correlation with the PCA axes and are represented as blue dashed lines. Plant trait abbreviations are the following: aluminum (AL), calcium (CA), carbon (C), copper (CU), diameter at breast height (DBH), leaf area (LEAFAREA), leaf dry matter content (LDMC), leaf mass per area (LMA), leaf thickness (LEAFTHICK), manganese (MN), mortality (MORT), nitrogen (N), phosphorus (P), potassium (K), relative growth rate (RGR), and zinc (ZN)
