摘要
P>The leaf 經濟s spectrum describes biome-invariant 縮放律 functions for leaf functional traits that relate to global primary productivity and nutrient cycling. Here, we develop a comprehensive framework for the origin of this leaf 經濟s spectrum based on venation-mediated 經濟 strategies. We define a standardized set of traits - density, distance and loopiness - that provides a common 語言 for the study of venation. We develop a novel quantitative model that uses these venation traits to model leaf-level physiology, and show that selection to optimize the venation 網絡 predicts the mean global trait-trait 縮放律 relationships across 2548 物種. Furthermore, using empirical venation data for 25 plant 物種, we test our model by predicting four key leaf functional traits related to leaf 經濟s: net carbon assimilat
