Abstract
International audience; 1. The food web of the central Amazon basin displays one of the largest discrepancies in food source utilisation versus availability for consumers. While C 4 macrophytes dominate the primary producing biomass in floodplains, the food web is dominated by the use of C 3 carbon sources. Amazon fish species have wide-ranging diets and show feeding flexibility in response to spatial and temporal patterns in food source availability. Fish are therefore expected to use a range of available resources. Fatty acids and stable carbon and nitrogen isotopic compositions were studied to investigate their trophic behaviour and provide a better assessmen...
