Dear Listmembers,

I work with crustaceans (and amphipods in particular) and I'd like to
determine tissular turnover of species displaying different feeding type. I
read a lot about experiments using C3 and C4 plants to trace the carbon but
I wonder how to label other type of food to obtain diet enriched in 13C or
in 15N (to conduct experiments with carnivores or scavengers for example).
If you have any reference on this topic, or any experience you're ready to
share, please let me know  !
Thanks a lot for your help
Regards
Fabienne
