Nitrogen isotope composition of amino acids reveals trophic partitioning in two sympatric amphipods

Abstract According to ecological theory, two species cannot occupy the same niche. Using nitrogen isotope analyses (δ15N) of amino acids, we tested the extent to which two sympatric deposit‐feeding amphipods, Monoporeia affinis and Pontoporeia femorata, partition their trophic resources. We found th...
