Fig. 3: PCA of Climatic Niche Differences for Pseudotsuga menziesii and Quercus chrysolepis.
From: Forest fires and climate-induced tree range shifts in the western US
PCA plot of the climatic niches of seedling-only and tree-plus-seedling plots of the two species where SORD is greater in burned areas (Table 2). PC1 and PC2 explain 84.5% of the variation across all 4 climate variables. Centroids are shown as large points. Similar PCA plots for all species can be found in Supplementary Fig. 1. Source data are provided as a Source Data file.
