Nitrogen concentrations of fruits at different sites in Madagascar and the Neotropics.

Letters and numbers listed in the first column refer to sites shown in Figure 2. Values of the published datasets (sites marked by letters in the left hand column and in Figure 2) are means or medians as listed in the original reference; sample size listed in brackets. For samples analyzed in the context of the present paper (sites marked by numbers) values are means and standard deviations. Nitrogen concentrations were recorded by general sampling (GS) of fruits from woody plant species available during the study period, or of fruits consumed by a specific primate species (PF) plus fruits not consumed by primates at the sites (NPF).
