Autotrophic carbon sources for fish of the central Amazon

Stable isotope data for plants and 35 fish species were used to identify autotrophic carbon sources for the central Amazon fish community. δ13C values for plants ranged from -39.4 to -11.9‰ with averages of -33.3, -28.8, -27.6, -26.2, and -12.8‰ for phytoplankton, flooded forest trees, C3 aquatic ma...
