Relationships between leaf traits and relative daily photon flux (logDPFrel) for T. melinonii (white dots) and D. guianensis (black dots). Simple linear regressions were represented by solid lines for T. melinonii and by dotted lines for D. guianensis. Regression equation and r² are indicated for statistically significant linear regressions (P < 0.05). Significance levels: ns, P > 0.05; *, P 60.05; **, P 60.01; *** and P 60.001.
