Figure 3: Relationships among ant species richness, disturbance class, spatial heterogeneity, and productivity (normalized difference vegetation index (NDVI), which is proportional to bubble size) for 40 sites at Fort Benning, Georgia. Species richness and spatial heterogeneity peak with intermediate disturbance. NDVI decreases monotonically with increasing disturbance. After Graham et al. [32].
