摘要

Trees are networked systems that capture energy, move massive amounts of water and material, and provide the setting for human society and for the lives of many associated organisms. Tree survival depends on making and breaking the right connections within these networks (photo, right). Although many of these connections also occur in herbaceous plants, they are even more important in trees due to their potentially great size and age. Connections support the flow of water, biomolecules and essentialelements from where they are obtained or produced to where they are stored and used. Within each living tree, these connections occur across a wide range of scales, such as between individual living cells; between tissues, like phloem (inner bark) and sapwood; and among plant organs, like leaves, branches, stems and roots. This article outlines a few of the connections in healthy wood and foliage, and how breaking these connections can also be part of healthy maturation and seasonal cycles.
