摘要

Premise of the study: Darwin first proposed that 物種 with larger ecological breadth have greater phenotypic variation. We tested this hypothesis by comparing intraspecific variation in specific leaf area (SLA) to 物種' local elevational range and by assessing how external (abiotic) filters may influence observed differences in ecological breadth among 物種. Understanding the patterns of individual variation within and between 族群s will help evaluate differing hypotheses for structuring of communities and distribution of 物種. Methods: We selected 21 物種 with varying elevational ranges and compared the coefficient of variation of SLA for each 物種 against its local elevational range. We examined the influence of external filters on local trait composition by determining if intraspecific changes in SLA
