Fig. 2: Architectural traits acquired using a Terrestrial Laser Scanner (TLS) in Central Amazonia varied with tree height and were affected by edge effects.
From: Edge effects on tree architecture exacerbate biomass loss of fragmented Amazonian forests
Nonlinear mixed-effects models were used to predict a surface area per unit volume (m2 m−3) of branches, b surface area per unit volume (m2 m−3) of trunks, c path fraction, d asymmetry, e relative crown depth (m m−1), and f relative crown width (m cm−1) of trees in forest edges (orange) and forest interior (green). Each line corresponds to the model prediction obtained by fitting 200 randomised permutations of subsets split into 80/20 for calibration and validation, respectively. Plot titles indicate the ecological meaning of high trait values. TLS-based trees are shown for a visual representation of the variation between low and high trait values.
