Methodology
  • Six leaf traits, one wood trait, and crown volume, were measured on trees of six species. Canopy branches and leaves were collected for most of the trees from six species located along an elevational gradient. For the leaf traits, three healthy and fully developed leaves located in the most distal part of the branches were collected. For measuring wood specific gravity, tree branches were selected and we followed Swenson et al. 2008 to calculate volume and wood specific gravity. For crown volume, tree crown area and crown depth were measured. For crown area, the distance from the tree's trunk to the crown edge in the four azimuth directions was measured using a decameter. For crown depth, the height from the first branch of the tree to the top of the crown using a laser rangefinder (True Pulse 360/360B, USA) was measured. The crown area was calculated assuming an ellipsoid shape, and then this value was multiplied by the crown depth to calculate crown volume.
