Patterns of chemical variation are displayed for individuals in this study. Taxa comprise the columns of the matrix and are ordered according to their inferred phylogenetic relationships. Groups of columns are colored according to their designated Piper clade. Black circles within the phylogenetic tree designate nodes with posterior support values greater than 85%. Each row of the matrix represents a metabolite class that was detected from 1H NMR and MS-based methods, and dark grey cells indicate the presence of that class in that taxa. Classes are hierarchically nested; capitalized font signifies the three classes at the highest level (and coarsest resolution), italicized font signifies the intermediate level, and black font signifies the lowest level (and highest resolution). Rows outlined in white indicate traits that were analyzed for phylogenetic signal in Radula. To the left of the matrix are representative compounds for a subset of metabolite classes that were detected in our samples.
