Figure 2From: Relative Bark Thickness is Correlated with Tree Species Distributions along a Fire Frequency GradientMean (+SE) relative bark thickness of individuals <10 cm diameter (A), individuals ≥10 cm diameter (B), and all individuals (C), and the inner bark proportion of individuals <10 cm diameter (D), individuals ≥10 cm diameter (E), and all individuals (F) of each species. Different letters represent significant differences among species at α = 0.05. Species are ordered from left to right according to their location along the pocosin-to-savanna gradient.Back to article page
