Biochemical composition of the cold-water coral Dendrophyllia cornigera under contrasting productivity regimes: insights from lipid biomarkers and compound-specific isotopes
Highlights • Higher lipid content in D. cornigera in Cantabrian Sea than in Menorca Channel. • Lipid composition and δ13C values reflected contrasted food captured by corals. • Feeding on phytoplankton and herbivorous grazers by Cantabrian D. cornigera. • Main trophic role of dinoflagellates and inv...
