The model of West, Brown and Enquist showed that total hydraulic resistance in trees can be independent of path length, provided that vascular conduits taper sufficiently. This model assumes that the tree branch network is volume-filling, so that segment lengths increase exponentially from tree top to base. We show that partial buffering of hydraulic(More)
The model of West, Brown and Enquist (1999) shows that hydraulic resistance in trees can be independent of path length, provided that vascular conduits widen sufficiently from tree top to base. We demonstrate that this result does not depend theoretically on branching architecture or cross-sectional conductive area of the stem. Previous studies have shown(More)
The model of West, Brown and Enquist (1999) showed that total hydraulic resistance in trees can be independent of path length, provided that vascular conduits taper sufficiently. The original model defined the coefficient of taper, a bar, in terms of conduit radius and segment number, but segments can be difficult to distinguish in old stems. Adhering(More)
