Tree Physiology promotes research in a framework of hierarchically organized systems, measuring insight by the ability to link adjacent layers: thus, investigated tree physiology phenomenon should seek mechanistic explanation in finer-scale phenomena as well as seek significance in larger scale phenomena (Passioura 1979). A phenomenon not linked downscale is merely descriptive; an observation not linked upscale, might be trivial. Physiologists often refer qualitatively to processes at finer or coarser scale than the scale of their observation, and studies formally directed at three, or even two adjacent scales are rare. To emphasize the importance of relating mechanisms to coarser scale function, Tree Physiology will highlight papers doing so particularly well as feature papers.
Tree Physiology welcomes submissions of manuscripts on research of non-tree woody and arborescent species (shrubs, vines, tree ferns, palms, bamboo). It invites submissions on new methods designed to improve estimates of quantities of structural components and flux of matter, energy and information relevant to the structure and the function of these species.
Tree Physiology also welcomes those manuscripts on genomics demonstrating a clear link and relevance to tree physiology.
Authors who prepared short, hard-hitting manuscripts are encouraged to submit them as Tree Physiology Letters that will be fast tracked through the review process with the help of the Editorial Review Board.
