The relationship between latitude and (A) fuel deposition rates (FDR), corrected for lean body mass (M^0.54), in 13 shorebird species measured as mass increase in g day⁻¹, (B) mean net primary productivity (NPP) at the sites where FDR and biomass data were collected, measured as a function of chlorophyll a, available light, and the photosynthetic efficiency, and (C) total intertidal biomass (biomass). All locations of data collection are shown in Figure 1.
