Adler, Frederick R. | Is space necessary? Interference competition and limits to biodiversity | A single trade-off between competitive ability and mortality has been shown to support an arbitrarily large number of species in models of interference competition in spatially structured populations. We show that this results not from spatial structure, but instead from the assumption that a small ... | Mortality rate; Competitive ability; Seed size | 2000 |

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 |
