Fig. 2.

The rate of expansion of young leaves expressed as the percentage increase in area per day (% per day) versus the chlorophyll content (mg·m⁻²) for Inga species from Panama (n = 11) and Peru (n = 23). For all species combined, there is a significant negative relationship [exp = 971 × (chl^−0.68); r² = 0.50, P < 0.0001]. The dotted diagonal line separates species into two equal-sized groups designated as defense and escape.
