Ecology of food chain in freshwater systems

We use compound specific nitrogen isotopes on amino acids to characterize food chains in lakes of Greenland and Switzerland.
To better understand the formation of isotopic carbon and nitrogen signals in organisms of a food chain from algae, zooplankton, small fish, top predators we use simple lakes systems in Greenland and experimental systems (ponds in Dübendorf).
This is a new project which started in September, come back to follow up.
