Cannibalism and trophic structure in a high Arctic lake: insights from stable-isotope analysis
Stable-nitrogen ( 15 N/ 14 N) isotope ratios (from 2.1‰ in moss to 14.5‰ in Arctic char, Salvelinus alpinus), showed enrichment with trophic level in the food web of Char Lake, Northwest Territories, and may be used to infer trophic position. The average 15 N enrichment of 1.5‰ between moss or algae...
