文摘
- •
The input of continental organic matter (OM) was studied in the trophodynamic system of a shelf area (NW Mediterranean).
- •
Stable isotopic composition and biochemical components of sedimentary OM were used as input proxies.
- •
The highest continental influence was observed within the 50-m isobaths (3–4 km from the coast).
- •
Allochthonous carbohydrates were recycled by microbiota, allowing terrigenous OM entrance in the lower food web.
- •
Macrofaunal organisms consumed allochthonous OM, but also selected autochthonous OM and prey.
