Diterpenes from the endangered goldenrod Solidago shortii.
Species extinction is tantamount to loss of chemical diversity, and so it is important to seize all opportunities to study species on the brink of extinction. Such studies are often hampered by the limited material available, but that obstacle is surmountable through collaboration with botanical gardens and advances in instrumentation. The goldenrod Solidago shortii is one example of an endange...
متن کاملPlastic Relationships between Reproductive and Vegetative Mass in Solidago Altissima.
To test several predictions of a model of linear, size-dependent reproductive output in plants, we analyzed the relationship between shoot vegetative (v) and reproductive (r) mass in five experiments on Solidago altissima from an invading population in Switzerland. There was large environmentally-induced and genetic variation in r and v. A large amount of variation in r could be explained by va...
متن کاملClumped distribution patterns in goldenrod aphids: genetic and ecological mechanisms
1. The aphids Uroleucon tissoti and U. nigrotuberculatum both exhibit significantly aggregated distribution patterns across clumps of their common host plant Solidago altissima, the tall goldenrod. However, U. nigrotuberculatum is significantly more aggregated than is U.tissoti. We tested the hypothesis that goldenrod genotype-by-U. tissoti genotype interactions for aphid performance characters...
متن کاملRelaxation of herbivore-mediated selection drives the evolution of genetic covariances between plant competitive and defense traits.
Insect herbivores are important mediators of selection on traits that impact plant defense against herbivory and competitive ability. Although recent experiments demonstrate a central role for herbivory in driving rapid evolution of defense and competition-mediating traits, whether and how herbivory shapes heritable variation in these traits remains poorly understood. Here, we evaluate the stru...
متن کاملIntraspecific diversity and dominant genotypes resist plant invasions.
Numerous studies have asked whether communities with many species deter invasions more so than do species-poor communities or whether dominant species deter invasion by colonizing species. However, little is known about whether high intraspecific diversity can deter biological invasions or whether particular genotypes might deter invasions. In this study, we present experimental evidence that i...
