The stoichiometry of dissolved organic carbon, nitrogen and phosphorus release by a planktonic grazer, Daphnia

We examined the relationship between Daphnia release rates and ratios of dissolved organic carbon (DOC), nitrogen (N), and phosphorus (P) and the elemental composition of algal food. We constructed a three-element (C, N, and P) mass-balance model to explore the relationships between food elemental composition and Daphnia release of DOC, N, and P. The model predicts that Daphnia DOC: N and DOC: P release ratios will increase with increasin
