Tracing anthropogenic inputs in stream foods webs with stable carbon and nitrogen isotope systematics along an agricultural gradient
Stable carbon ((13)C) and nitrogen isotopes ((15)N) are useful tools in determining the presence of agricultural influences in freshwater ecosystems. Here we examined δ(15)N and δ(13)C signatures in nitrate, fish, and mussel tissues, from rivers in Southern Ontario, Canada, that vary in their catchm...
