Virola surinamensis 20 12 1–38.9 0.177–0.417 cd 0.08–0.95 a –1148 to –124 bc
Cecropia obtusa 20 11 1–26.5 0.168–0.323 d 0.07–0.77 a –2244 to –5 c
Pachira aquatica 20 15 0.7–30.6 0.2–0.429 bc 0.08–1.27 a –3702 to –1223 d

For each species, the observed range (minimum–maximum) of each trait is given.

Different letters indicate statistical differences between species. N, number of trees used to measure morphometry and density; NBRLS, number of trees used to measure residual bark strain.
