Figure 6 . Arthropod species retention rates (Zeta ratio)
calculated from MOTU databases retrieved using the COI (A ) and
16S (B ) markers. The Y-axis (Z-ratio) shows the percentage of
species shared by all trees as the number of trees included in the
analyses increases (Zeta order). Control trees and those at short-term
(1 year) and long-term (10 years) exclosures are depicted by grey
squares, orange circles and blue squeres, respectively.
