Fig. 2: Estimated marginal effects of latitude on organismal P content.

A Latitudinal patterns for autotrophs vs. heterotrophs, pooled across realms. B Latitudinal patterns for freshwater vs. terrestrial organisms, pooled across trophic groups. C Latitudinal patterns for freshwater and terrestrial autotrophs vs. heterotrophs. Model fit lines indicate significant (solid; P < 0.05) or non-significant (dotted; P > 0.05) relationships from linear mixed-effect models. Data points and estimates are shown on the logit scale and back-transformed to % dry mass. P values are from two-sided tests with permuted t-statistics and were adjusted for multiple comparisons. Supplementary Table 1 for slope coefficients on the logit scale and exact P values.
