Figure 2. Species accumulation curves for documenting
completeness of sampling. (A) Butterflies in rural habitats, (B)
butterflies in urban habitats, (C) birds in rural habitats, (D) birds in
urban habitats, (E) vegetation in rural habitats, and (F) vegetation in
urban habitats. The thick black line is the species accumulation curve
estimated using the Mao Tao method with 95% confidence intervals shaded
in grey. The number of species identified is shown, along with the
number of species predicted for twice the number samples collected, and
percentage completion of sampling.
