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.

Annual Review of Ecology, Evolution, and Systematics, 2002
▪ 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.

Aboveground–belowground herbivore interactions: a meta‐analysis [PDF]
Ecology, 2012 Research investigating interactions between aboveground (AG) and belowground (BG) herbivores has been central to characterizing AG–BG linkages in terrestrial ecosystems, with many of these interactions forming the basis of complex food webs spanning the ...

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 ...

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 ...

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 ...

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?

Large herbivores can influence the population dynamics of their forage plants. Feeding means a disturbance for the affected plants. Although in most cases herbivores consume only a relatively small fraction of the total phytomass, they influence the intra- and interspecific competition between plants. Whether and to what extent herbivores influence the

The Chrysomelidae: A useful group for investigating Herbivore-Herbivore interactions
1988The Chrysomelidae comprise one of the most abundant and diverse families of herbivorous insects. A large proportion of chrysomelid species are monophagous or oligophagous, and the group has long been used to investigate the evolution of host specificity in phytophagous insects (Mitchell 1981, Smiley 1982, Crowson 1981, p. 589, Jolivet 1986).
