Figure 5.

Relationship between region size and diversity estimates. Top row (A.-C.) shows the mean relationship (solid gray line) and 95% confidence interval (dotted gray lines) between size of sampling window and biodiversity. Selected relationships for individual sites (black dotted lines) highlight the range of patterns. The bottom row (D. – F.) shows the corresponding histograms of slopes for individual sites. For example, the relationship between β-diversity (measured as mean dissimilarity) and sampling area size tended to be weakly positive (B.).
