Inducible Plant Responses Linking Above- and Below-ground Herbivory: Ecological Significance and Underlying Mechanisms
Title: INDUCIBLE PLANT RESPONSES LINKING ABOVEAND BELOW-GROUND HERBIVORY: ECOLOGICAL SIGNIFICANCE AND UNDERLYING MECHANISMS Ian Kaplan, Doctor of Philosophy, 2007 Directed By: Professor Robert F. Denno, Department of Entomology Aboveand below-ground organisms can indirectly affect one another via several recently-described mechanisms, one such mechanism being herbivore-induced plant responses. ...
متن کاملAbove-ground herbivory by red milkweed beetles facilitates above- and below-ground conspecific insects and reduces fruit production in common milkweed
1. Initial herbivory and induced plant responses can influence subsequent aboveand below-ground herbivore attack. When two life stages of the same herbivore damage different plant parts sequentially, there is strong potential for plants to respond with induced plant defence against the later attacker. Alternatively, the earlier attacker could manipulate the host plant to facilitate the later-fe...
متن کاملBelow-ground plant–fungus network topology is not congruent with above-ground plant–animal network topology
In nature, plants and their pollinating and/or seed-dispersing animals form complex interaction networks. The commonly observed pattern of links between specialists and generalists in these networks has been predicted to promote species coexistence. Plants also build highly species-rich mutualistic networks below ground with root-associated fungi, and the structure of these plant-fungus network...
متن کاملHerbivory reduces plant interactions with above- and belowground antagonists and mutualists.
Herbivores affect plants through direct effects, such as tissue damage, and through indirect effects that alter species interactions. Interactions may be positive or negative, so indirect effects have the potential to enhance or lessen the net impacts of herbivores. Despite the ubiquity of these interactions, the indirect pathways are considerably less understood than the direct effects of herb...
متن کاملFacilitation and inhibition: changes in plant nitrogen and secondary metabolites mediate interactions between above-ground and below-ground herbivores.
To date, it remains unclear how herbivore-induced changes in plant primary and secondary metabolites impact above-ground and below-ground herbivore interactions. Here, we report effects of above-ground (adult) and below-ground (larval) feeding by Bikasha collaris on nitrogen and secondary chemicals in shoots and roots of Triadica sebifera to explain reciprocal above-ground and below-ground inse...
