Table 2 Mean ± standard deviation of basic density (ρ; g m−3), contractions (%), and anisotropy (%) of wood from the three dominant tree species in Amazonian mangroves. Rm: Rhizophora mangle; Ag: Avicennia germinans; Lr: Laguncularia racemosa; ρ: basic density (kg m−3); R: radial position (%); T: tangential position (%); VV: volumetric variation (%); p: significance level
