摘要

Plant vascular 網絡s are central to botanical form, function, and 多樣性. Here, we develop a theory for plant 網絡 縮放律 that is based on optimal space filling by the vascular system along with trade-offs between hydraulic safety and efficiency. Including these 演化ary drivers leads to predictions for sap flow, the taper of the radii of xylem conduits from trunk to terminal twig, and how the frequency of xylem conduits varies with conduit radius. To test our predictions, we use comprehensive empirical measurements of maple, oak, and pine trees and complementary literature data that we obtained for a wide range of tree 物種. This robust intra-and interspecific assessment of our botanical 網絡 model indicates that the central tendency of observed 縮放律 properties supports our predictions much better than the
