Our model for the worldwide leaf economics spectrum (LES) based on venation networks (Blonder et al., 2011, 2013) was strongly criticized by Sack et al. (2013) in this journal. Here, we show that the majority of criticisms by Sack et al. are based on mathematical and conceptual misunderstandings. Using empirical data from both our original study as well as others in the literature, we show support for our original hypothesis, that venation networks provide predictive power and conceptual unification for the LES. In an effort to reconcile differing viewpoints related to the role of leaf venation traits for the LES, we highlight several lines of further investigation.
我们基于叶脉网络建立的全球叶片经济谱（LES）模型（Blonder等人，2011年、2013年）受到了Sack等人（2013年）在本期刊上的强烈批评。在此，我们表明Sack等人的大多数批评基于数学和概念上的误解。利用我们原始研究以及文献中其他研究的实证数据，我们证明了对我们原始假设的支持，即叶脉网络为叶片经济谱提供了预测能力和概念上的统一。为了调和与叶片叶脉特征在叶片经济谱中作用相关的不同观点，我们强调了几条进一步研究的方向。
