Relative abundance of phylogenetic nifH clusters based on classification and regression trees (CART) analysis. On the x-axis, every bar represents the diazotrophic community of an individual ant colony, grouped by patch type (initial patch, established patch) and ant species (Azteca alfari, A. constructor, A. xanthochroa), whereas the y-axis shows the relative read abundance
