Insect herbivory stimulates allelopathic exudation by an invasive plant and the suppression of natives
Giles C. Thelen, Jorge M. Vivanco, Beth Newingham, William Good, Harsh P. Bais, Peter Landres, Anthony Caesar and Ragan M. Callaway* Abstract Exotic invasive plants are often subjected to attack from imported insects as a method of biological control. A fundamental, but rarely explicitly tested, assumption of biological control is that damaged plants are less fit and compete poorly. In contrast...
متن کاملInsect herbivory and plant adaptation in an early successional community.
To address the role of insect herbivores in adaptation of plant populations and the persistence of selection through succession, we manipulated herbivory in a long-term field experiment. We suppressed insects in half of 16 plots over nine years and examined the genotypic structure and chemical defense of common dandelion (Taraxacum officinale), a naturally colonizing perennial apomictic plant. ...

متن کاملAlteration of Plant Primary Metabolism in Response to Insect Herbivory.
Plants in nature, which are continuously challenged by diverse insect herbivores, produce constitutive and inducible defenses to reduce insect damage and preserve their own fitness. In addition to inducing pathways that are directly responsible for the production of toxic and deterrent compounds, insect herbivory causes numerous changes in plant primary metabolism. Whereas the functions of defe...
متن کاملAboveground insect herbivory increases plant competitive asymmetry, while belowground herbivory mitigates the effect
Insect herbivores can shift the composition of a plant community, but the mechanism underlying such shifts remains largely unexplored. A possibility is that insects alter the competitive symmetry between plant species. The effect of herbivory on competition likely depends on whether the plants are subjected to aboveground or belowground herbivory or both, and also depends on soil nitrogen level...
