From: A review of fire effects across South American ecosystems: the role of climate and time since fire
Weighted-mean effect sizes and 95% bias-corrected confidence intervals of fire on soil properties from studies published between 1990 and 2019 that were used in the review of fire effects across South American ecosystems to determine the role of climate and time since fire. (A) Effect sizes of bulk density, litter, organic matter (OM), total nitrogen (Total N), available nitrogen (N), phosphorous (P), micronutrients, pH, and salinity are shown. (B) Effect sizes of early (-early) and late (-late) post-fire time of organic matter, total nitrogen, available nitrogen, phosphorous, and within climate type (-humid-warm, -humid-cold, -semiarid) of organic matter and total nitrogen. Parameters with confidence intervals that do not overlap the vertical dotted line (Hedge’s d = 0) are considered to have a significant positive or negative effect. Sample sizes for each category are shown in parentheses. The size of each black dot is proportional to its weight or contribution to the overall mean calculation. Asterisk (*) denotes a significant difference (Q-between [Qb] statistics) among categories (* = P < 0.05)
