Nitrogen isotopic composition of amino acids reveals a variety of trophic ecology of organisms inhabiting chemosynthesis-based ecosystems

Abstract To understand the trophic interactions between various organisms in chemosynthesis-based ecosystems (CBEs) and the metabolic interaction between host animal and its symbiont, we estimated the trophic position (TP) using the stable nitrogen isotopic compositions of glutamic acid and phenylal...
