ABSTRACT The continental slope of the Gulf of Mexico supports dense aggregations of tubeworms and mussels that have symbiotic chemoautotrophic bacteria. Associated with these communities are numerous heterotrophic fauna and free-living bacteria. Here we examine the stable C, N, and S isotope compositions of fauna from two chemoautotrophic communities to identify isotope ranges of chemoautotrophic primary production and determine the usage of that primary production by heterotrophic ...
