Fig. 8From: treeman: an R package for efficient and intuitive manipulation of phylogenetic treesUsing calcOvrlp() to test for phylogenetic turnover. Left, phylogenetic trees with distributions of taxa found in two non-overlapping communities (red and blue) randomly generated with phylogenetic distance bias. The strength of this bias is determined by psi; greater psi leads to reduced overlap between communities. Right, distribution of 99 iterations for null communities’ overlap in phylogenetic diversity with red community. Red line indicates observed overlap between red and blue communities Back to article page
