Fig. 1From: Influence of tree species, tree diameter and soil types on wood density and its radial variation in a mid-altitude rainforest in MadagascarAverage wood density according to a tree species, b light requirement–SS semi-shade-tolerant, PLD pioneer light demander, NLD nomad light demander, c soil types–AF acric ferralsol, OF orthic ferralsol, XF xanthic ferralsol, E entisols, SLC soils of lowland complex. Box plot shows the median, quartiles, lowest and highest data. Identical letters indicate no statistical difference in wood density value (ANOVA and Fisher’s LSD test, p < 0.05)Back to article page
