Table 3 Relationships between protective, flammability, and physiological trait principal components analysis axes. Flam 1 and Flam 2 correspond to the first and second axes of flammability (litter burning and drying), respectively. Bark 1 and Bark 2 correspond to the first and second axes of protective traits (bark and wound response), respectively. Phys 1, Phys 2, and Phys 3 correspond to the first, second, and third axes of physiological traits, respectively. Values in columns are correlation coefficients (r).
