Fig. 1: Direction and magnitude of edge effects on forest biomass density.
From: A globally consistent negative effect of edge on aboveground forest biomass
a, Map of edge effects (\(\frac{\Delta {\rm{Aboveground}}\; {\rm{biomass}}\; {\rm{density}}}{\Delta {\rm{log}}_{10}({\rm{Distance}}\; {\rm{to}}\; {\rm{edge}})}\) or \(\frac{\Delta {\rm{AGB}}}{\Delta D}\)), calculated individually within each 100-km grid cell using spatial log-linear regression (Methods). A more positive \(\frac{\Delta {\rm{AGB}}}{\Delta D}\) corresponds to a greater decrease in aboveground biomass density near the forest edge relative to the interior. b,c, Histograms of longitude (b) and latitude (c) for sampled forest locations. d, Mean ± s.d. of \(\frac{\Delta {\rm{AGB}}}{\Delta D}\) by forest biomes weighted by inverse coefficients of variation.
