WebbFor species richness (q = 0), the increasing sample size-based rarefaction and extrapolation curves for exclosure plots revealed that data were insufficient to infer “true” species richness, because some rare tree species might not have been detected within the set of study plots but could have occurred in the surrounding study region (Figure 1, left … WebbGenerate a tree for phylogenetic diversity analyses. QIIME supports several phylogenetic diversity metrics, including Faith’s Phylogenetic Diversity and weighted and unweighted UniFrac. In addition to counts of features per sample (i.e., the data in the FeatureTable [Frequency] QIIME 2 artifact), these metrics require a rooted phylogenetic ...
