Predicted, measured, and estimated species richness for trees and arthropods.

<p>Small open circles are predicted arthropod diversity, small open squares are predicted tree diversity. Large open circle is measured arthropod diversity and large open squares are measured or estimated tree diversity. Filled circles are predicted arthropod diversity at the scale of the Reserve and of Panama, filled squares are predicted tree diversity at those same scales. The X marks the previous estimate for arthropod diversity at the reserve scale of Basset et al.
