Particulate matter (PM_2.5; A) and total volatilized CO₂ emissions (B). Grey circles are plot-level values with gradient indicating mortality (total) percent. Site means and standard errors are in black. Note variable scales between sites. Letters indicate significant differences between timesteps (p < 0.05; Wilcoxon signed-rank test for comparisons). Sites are located on the Los Padres and Sierra National Forests (NF)
