Linking leaf and tree water use with an individual-tree model

Estimation of Tree Biomass at Individual tree, Sample plot and Hybrid Level using Drone Images

Two-dimensional image conversion algorithms to 3D data create the hope that the structural properties of trees can be extracted through these images. In this study, the accuracy of biomass estimation in tree, plot, and hybrid levels using UAVs images was investigated. In 34.8 ha of Sisangan Forest Park, using a quadcopter, 854 images from an altitude of 100 meters above ground were acquired. SF...

Linking leaf veins to growth and mortality rates: an example from a subtropical tree community

A fundamental goal in ecology is to link variation in species function to performance, but functional trait-performance investigations have had mixed success. This indicates that less commonly measured functional traits may more clearly elucidate trait-performance relationships. Despite the potential importance of leaf vein traits, which are expected to be related to resource delivery rates and...

Water use efficiency of short-rotation Salix viminalis at leaf, tree and stand scales.

Fluxes of water and carbon dioxide from short-rotation Salix viminalis L. were measured at leaf, tree and stand scales using porometer, chamber and micrometeorological techniques, respectively. At all three scales, instantaneous water use efficiency exhibited a similar dependence on vapor pressure deficit (deltae) with values of 21, 13 and 10 g CO(2) per kg H(2)O for deltae of 0.5, 1.0 and 1.5 ...
