Data from: A critical assessment of the stoichiometric knife-edge: no evidence for artefacts caused by the experimental P-supplementation of algae

Steven Declerck & Libin Zhou
The stoichiometric knife-edge refers to the reduced performance of consumers encountering food with excess phosphorus (P) relative to carbon (C) or nitrogen (N). Studies that provide evidence for such knife-edge in aquatic systems often apply phosphate supplementation to create P-rich food treatments. However, this method may suffer from artefacts, because after uptake algae may store P in a form different from the P-rich biomolecules typically consumed by zooplankton. Our aim was to test if P...
