Fig. 1From: Morphological variation of fine root systems and leaves in primary and secondary tropical forests of Hainan Island, ChinaConceptual diagram of commonly measured aboveground and belowground functional traits along an acquisitive-conservative life-history continuum (i.e., fast-slow plant spectrum; Reich 2014). Hypotheses for how within-species (i.e., intraspecific) variation in root and leaf morphologies should relate to increasing forest age (i.e., forest succession) are shown in black (see research question 1)Back to article page
