▪ Abstract Herbivore offense describes traits that allow herbivores to increase their feeding and other uses of host plants when these uses benefit the herbivores. We argue that ecological interactions and coevolution between plants and herbivores cannot be understood without an offense-defense framework.

When is a herbivore not a herbivore?
Oecologia, 1985Young herbivores are not herbivores. With the apparent exception of some chewing insects they cannot survive and growth without eating animal or microbial protein. Further reinforcing how short available nitrogen is in plant food, adult herbivores must feed selectively and depend on intestinal microorganisms to obtain sufficient nitrogen for ...

Herbivores and Plant Diversity
The American Naturalist, 1992We study spatial lottery models of competition between two plant species in which competitive ability is affected by levels of herbivory. Herbivory may enhance plant diversity in two qualitatively different ways. The first is global frequency dependence; the level of herbivory suffered by a plant decreases as the species becomes rare.

The specificity of herbivore-induced plant volatiles in attracting herbivore enemies
Trends in Plant Science, 2012Plants respond to herbivore attack by emitting complex mixtures of volatile compounds that attract herbivore enemies, both predators and parasitoids. Here, we explore whether these mixtures provide significant value as information cues in herbivore enemy attraction.

Herbivore Diets, Herbivore Colonization, and the Escape Hypothesis
Ecology, 1990The escape hypothesis predicts that isolated individuals of a given plant species will escape their specialized herbivores and so survive better than individuals growing in clumps. This phenomenon could promote plant coexistence. I examined assumptions underlying the hypothesis by considering insect herbivores associated with neotropical Passiflora ...

Serotonin Metabolism in Herbivores
Nature, 1958RECENTLY, Erspamer1 has reported that the urine of adult rabbits, guinea pigs and horses contains no detectable 5-hydroxyindoleacetic acid, which is found in the urine of men, dogs and rats as an important metabolic product of endogenous serotonin. He has suggested that in adult herbivores the metabolic pathway for serotonin may differ from that in ...

Plants, and the organisms that eat them, constitute the majority of terrestrial multicellular diversity (Speight et al., 2008). Indeed, co-evolutionary interactions between herbivores and plants are thought by some to be 'the major zone of interaction responsible for generating terrestrial organic diversity' with plant secondary metabolites (PSMs ...

Modification of the Savanna Functioning by Herbivores
2006Beyond consumption of a given amount of the net primary production (NPP), herbivores may have major effects on ecosystem structure, functioning and dynamics (e.g., [35]). Many authors have represented plant-herbivore interactions by predation-like relationships [8] assuming that herbivory has a purely negative impact on plant growth.

Trends in Ecology & Evolution, 1987
Two questions dominate current thinking on plant-herbivore interactions: what is the impact of feeding by herbivores on the distribution and abundance of plants; and what is the role of herbivory as an agency of natural selection, leading to differential performance of host plant genotypes?
