Figure 5. Total Fraxinus pennsylvanica antioxidants (A) andFagus grandifolia phenolics (B) in leaves of juveniles in central New Jersey, USA forests growing in fenced or unfenced plots and with noMicrostegium vimineum cover or high cover, defined as 12-65%. Graphs show least-squares means + 95% CL, backtransformed from log10. N for each mean, from right to left: A) 39, 4, 49, 4; B)33, 6, 28, 3. Based on adjustment for six multiple comparisons with the Tukey-Kramer method, means labeled in A with different letters were different at P = 0.005 (fenced/no cover vs. unfenced/high cover) and P=.03 (unfenced/no cover vs. unfenced/high cover). In B, they were different at P=0.04 (fenced/no cover vs. unfenced/high cover).
