Coley, Phyllis D. | Benefits and costs of defense in a neotropical shrub | Benefits and costs are central to optimality theories of plant defense. Benefit is the gain in fitness to reducing herbivory and cost is the loss in fitness to committing resources to defense. We evaluate the benefits and costs of defense in a neotropical shrub, Psychotria horizontalis. Plants were ... | Cost of defense; Growth-defense trade-off; Exclosures; Field experiment; Herbivory; Panama; Psychotria horizontalis; Rubiaceae; Tannins; Toughness; Tropics | 1995 |

Coley, Phyllis D. | Red coloration of tropical young leaves: a possible antifungal defense? | Many woody species in humid tropical forests synchronously flush entire canopies of young red leaves.

In the humid tropics, fungal attack is a potentially important source of mortality f... | Herbivory; Anthocyanin; Antifungal defense; Atta columbica; Panama; Leaf-cutting ants; Tropics; Young leaves | 1989 |

Others have tried t... | Arboreal ants; Tropics | 1996 |
