The trophic significance of epilithic algal production in a fertilized tundra river ecosystem
Fertilization of a pristine tundra river with phosphorus and nitrogen changed the nitrogen and carbon stable isotope ratios in epilithic algae. Determination of δ 15 N and δ' 3 C values in consumers allowed this algal organic matter to be traced in the food web for several kilometers downstream...
