Life on the stoichiometric knife-edge: effects of high and low food C:P ratio on growth, feeding, and respiration in three Daphnia species


Recently, data have emerged indicating that not only high food carbon:phosphorus (C:P) ratio but also low food C:P (P-rich food) can have negative effects on the growth of consumers. The shape of this “stoichiometric knife edge,” however, is not yet well-documented, and the mechanisms underpinning it are not understood. Here we report the results of… (More)
