    Tissue N, P, K, Ca, and Mg content was estimated in traps and photosynthetic and carnivorous shoots in five aquatic carnivorous plant species from an outdoor culture: Aldrovanda vesiculosa, Utricularia vulgaris, U. reflexa, U. intermedia, and U. stygia, for the determination of the mineral cost of carnivory. In three species with monomorphic shoots (A. vesiculosa, U. vulgaris, U. reflexa), tissue P and K content in traps was significantly higher than that in their photosynthetic shoots, whereas N content was about the same. The evolution of this plant group is considered to show the optimization of these mineral cost-benefit relationships.
