摘要
- Plant phenotypic 多樣性 is shaped by the interplay of trade-offs and constraints in 演化. Closely integrated groups of traits (i.e. trait dimensions) are used to classify plant phenotypic 多樣性 into plant strategies, but we do not know the degree of interdependence among trait dimensions. To assess how selection has shaped the phenotypic space, we examine whether trait dimensions are independent. 2. We gathered data on saplings of 24 locally coexisting tree 物種 in a temperate 森林, and examined the correlation structure of 20 leaf, branch, stem and root traits. These traits fall into three well-established trait dimensions (the leaf 經濟 spectrum, the wood spectrum and Corner's Rules) that characterize vital plant functions: resource acquisition, sap transport, mechanical support and canopy archite
