Inducible defenses: continuous reaction norms or threshold traits?

The American naturalist - 1 Sept 2011

Svennungsen Thomas Owens, Holen Øistein Haugsten, Leimar Olof

Abstract excerpt

Phenotypically plastic traits can be expressed as continuous reaction norms or as threshold traits, but little is known about the selective conditions that favor one over the other. We study this question using a model of prey defenses in which prey can induce any level of defense conditional on cues that are informative of local predator density. The model incorporates a trade-off between defense expression and...
