Figure 2 Species richness for different sites. A) 3 % radius OTU richness and zero radius OTU (zOTU) richness in barren lava, kīpuka edges, kīpuka centers, and continuous forest in Stainback and Kona Hema. B) Effect of kīpuka size on diversity of edge and center communities. The plots show kīpuka area on a log scale plotted against 3 % radius OTU richness and zOTU richness, for kīpuka centers on the left and edges on the right.
