Figure 2

Relationship between residual δ15N with mean annual temperature (MAT), mean annual precipitation (log transformed MAP), and nitrogen concentration ([N]). Residual δ15N is calculated relative to a model including the two remaining model effects. Globally distributed observations from 1273 species in black (n = 9828); observations of P. balsamifera (n = 755) in grey.
