synthesis, we accessed the full dataset available in online supplementary information with the article and selected available data on herbivory as a proportion of above-ground productivity, then calculated means for each of the major terrestrial biome types distinguished in the dataset. Further, we used the following relationship between and from figure 2 in McNaughton Fp Fc et (1989) to predict from measured at our study sites: al. Fc Fp Log = 2.04 (log 4.80 Fc Fp) – Where both and are in units of kJ m-2 yr-1. We converted units of energy to mass with the Fp Fc same standard factors applied in McNaughton (1989), for tropical rainforest vegetation et al. tissue caloric content of 3897 cal g-1 dry mass (Golley 1961).
