Figure 3

Distribution of model estimates on foliar δ15N for MAT, logMAP, and log[N] across 1000 samples of 755 observations in the global N database. Models were constructed as in Fig. 2. Samples were constrained to be within the climate range of P. balsamifera samples; the estimates of each effect using only P. balsamifera samples is represented by the vertical dotted line (also provided in Table 1).
