Detecting marine nutrient and organic matter inputs into multiple trophic levels in streams of Atlantic Canada and France.
We used stable isotope analysis in an attempt to detect marine subsidies from anadromous fish to freshwater benthos in four river systems draining to the AtlanticOcean. Benthic invertebrates in the West River, Nova Scotia, Canada, had elevated d13C, d15N, and d34S values in a downstream reach that s...
