| exposure of solidago altissima plants to volatile emissions of an insect antagonist (eurosta solidaginis) deters subsequent herbivory. | recent work indicates that plants respond to environmental odors. for example, some parasitic plants grow toward volatile cues from their host plants, and other plants have been shown to exhibit enhanced defense capability after exposure to volatile emissions from herbivore-damaged neighbors. despite such intriguing discoveries, we currently know relatively little about the occurrence and significance of plant responses to olfactory cues in natural systems. here we explore the possibility that s ... | 2013 | 23237852 |
| a test of genotypic variation in specificity of herbivore-induced responses in solidago altissima l. (asteraceae). | plant-induced responses to multiple herbivores can mediate ecological interactions among herbivore species, thereby influencing herbivore community composition in nature. several studies have indicated high specificity of induced responses to different herbivore species. in addition, there may be genetic variation for plant response specificity that can have significant ecological implications, by altering the competitive strength and hierarchical relationships among interacting herbivore specie ... | 2013 | 23807734 |
| influence of polyploidy on insect herbivores of native and invasive genotypes of solidago gigantea (asteraceae). | herbivores are sensitive to the genetic structure of plant populations, as genetics underlies plant phenotype and host quality. polyploidy is a widespread feature of angiosperm genomes, yet few studies have examined how polyploidy influences herbivores. introduction to new ranges, with consequent changes in selective regimes, can lead to evolution of changes in plant defensive characteristics and also affect herbivores. here, we examine how insect herbivores respond to polyploidy in solidago gig ... | 2009 | 19938375 |
| interactions between goldenrod (solidago altissima l.) and its insect herbivore (trirhabda virgata) over the course of succession. | consumers can mediate the composition of plant communities and alter ecosystem processes. although herbivores usually increase n availability in the short term, they might decrease it in the long term. i investigated the long-term effect of insect herbivores on leaf tissue quality and soil n availability in goldenrod (solidago altissima) fields using two approaches: (1) i compared plots from which herbivores had been excluded for 17 years with adjacent plots that had experienced normal levels of ... | 2000 | 28308345 |
