摘要
Abstract: 1. The Hawaiian silversword alliance is a spectacular example of plant adaptive radiation. The lineage includes 33 物種 in three endemic genera (Argyroxiphium, Dubautia and Wilkesia) that occupy almost all major habitats of the Hawaiian archipelago. 2. Here, we quantitatively explore functional diversification in the lineage by linking measurements of multiple leaf functional traits with 氣候 niche and 系統發育 data. 3. We show that leaf functional trait variation (i) spans much of the global angiosperm range, (ii) is best explained by a white-noise 演化ary model and (iii) is integrated in ways consistent with both the global leaf 經濟s spectrum and the predictions of leaf venation 網絡 theory. 4. Our results highlight the importance of functional diversification and integration in rapidly evo
