Figure 5

Large-scale estimates of dynamic gaps and relationship with tree mortality. (a) Dynamic gap (% year⁻¹) generated at 5-km spatial resolution from the lidar static-dynamic gaps relationship (Fig. 3) and gap/environmental-climate model (Table 1). (b) Relationship between estimated dynamic gap fraction and field-based tree mortality from Brienen et al.⁵. (c) Estimated dynamic gap (% year⁻¹) per Amazonian region using all values from the map (in blue, n > 40,000 pixels per boxplot) and just those corresponding to the field-plot locations (in orange, n = 88). The mean dynamic gap was statistically different between regions (p < 0.01). Dashed line represents the 1:1 line. R v4.0.2 was used to plot this figure³².
