Adler, Frederick R. | Defended fortresses or moving targets? Another model of inducible defenses inspired by military metaphors | We use a common framework to compare three models of plant strategies to confront herbivory: constitutive defense, optimal inducible defense, and the "moving target." Plants with constitutive defenses retain a fixed defensive phenotype. Plants with optimal inducible defenses respond to attack by inc... | Constitutive defense; optimal inducible defense; phenotype | 1994 |

Adler, Frederick R. | Departure time versus departure rate: how to forage optimally when you are stupid | Foragers unable to leave a patch at the optimal moment must act as constrained foragers. Extending the results of Houston and McNamara (1985), we compare a blundering forager that leaves patches at a constant rate with an unconstrained optimal forager that leaves patches at the optimal time. | Blundering Foragers; Foraging; Marginal Value Theorem | 1999 |
