Other claims from this paper (13)
- Association Goldenrods order their response to herbivory to favor maintenance of established individuals over seed production.
- Association Herbivore loads too low to affect stem length or density reduced the proportion of stems that bloomed and the size of inflorescences.
- Association Herbivore loads never reached levels that carried over to affect plant performance in the following year.
- Association Insects were not attracted to lush goldenrod plants that had escaped herbivore attack the previous year.
- Association Relatively small herbivore loads had effects on goldenrod that accumulated slowly over years.
- Association Herbivory accumulated over 6 years did not change the mass of goldenrod inflorescences.
- Observation Goldenrod stands in central New York are expected to have herbivore loads below 50 mg per metre of stem over 75% of the time.
- Association At chronic herbivore levels, herbivores moderately reduce goldenrod flower production.
- Association At chronic herbivore levels, herbivores have no measurable influence on goldenrod stem growth.
- Observation Herbivore loads are expected to exceed 200 mg per metre of stem on about 5% of the time.
- Association Such herbivore loads can completely inhibit goldenrod flowering.
- Association Such herbivore loads can severely stunt goldenrod vegetative growth.
- Association The herbivore pressures measured appear sufficient to act as potent agents for selecting between goldenrod genotypes.
