The importance of kelp to an intertidal ecosystem varies by trophic level: insights from amino acid δ13C analysis

Emma Elliott Smith, Chris Harrod & Seth D. Newsome
A fundamental question in ecology is understanding how energy and nutrients move through and between food webs, and which sources of production support consumers. In marine ecosystems, these basic questions have been challenging to answer given the limitation of observational methods. Stable isotope analysis of essential amino acids (EAA δ13C) has great potential as a tool to quantify energy and nutrient flow through marine food webs; however, it has been primarily utilized at large spatial...
