14C as a tool to trace terrestrial carbon in a complex lake: implications for food-web structure and carbon cycling.

Does carbon from terrestrial sources (e.g. peat decomposition) support the food chain in a large lake in Northern Ireland? Does the presence of zebra mussels affect the food chain? This project investigates carbon cycling and food web structure in lower Lough Erne. Radiocarbon (¹⁴C) and stable isotopes (¹³C and ¹⁵N) will be analysed from the dissolved inorganic carbon, dissolved and particulate organic matter and a range of invertebrates and fish to investigate carbon pathways and terrestrial influence on the food web.
