英文摘要: Abstract(#br)As deep-sea benthic ecosystems of continental margins provide numerous functions and services to humans, a better understanding of these key habitats and their communities is needed to help predict climate-driven shifts and support conservation efforts. Here stable isotope (δ 13 C and δ 15 N), elemental (%C, %N, and molar C:N), and fatty acid (FA) composition of 50 different deep-sea species, belonging to 7 major taxa, were analyzed in order to characterize their diet and trophic position, and to study the fate of energy and essential nutrients in the food web. In addition, relationships between depth and biochemical signatures (δ 13 C, δ 15 N, %C, %N, C:N m , and FAs) were also investigated, and %C, oleic acid (18:1ω9), and arachidonic acid (ARA, 20:4ω6) were found to...
