| Biogeochemistry and ecosystem ecology aim to advance our understanding of material flows within, and the functioning of, ecosystem. The (bio)geochemists provide quantitative rigor and tools for tracing flows, while ecologist emphasize the need to embrace biodiversity. The link between organism identity/activity and biogeochemical processes is still poorly known. I will discuss how organic geochemical tools, biogeochemical process studies and whole ecosystem isotope labelling studies can be combined to elucidate the flow of carbon and nitrogen through ecosystems and present examples from marine sediments, cold-water corals, sponges and phytoplankton. |
