Compared to constitutive resistance, facultative defenses imply a lower risk of pathogen adaptation (Boyd, 2006), as well as lower direct and indirect costs of defense under enemy-free conditions--for example, because energy is saved or exposure to autotoxic defensive compounds is reduced (Agrawal and Karban, 1999).
However, the existence of autotoxic effects suggests that a chemically mediated density-dependent predator death rate may stabilize Daphnia-phytoplankton interactions, just as it stabilized rotifer-phytoplankton interactions in this study.
