The effects of ungulate herbivory and nutrient variation on pollen reciept in Ipomopsis aggregata
Abstract
The purpose of this study was to investigate the effects of ungulate herbivory (clipped, unclipped) and nutrient variation (ambient, water added, fertilizer and water added) on conspecific and heterospecific pollen receipt to Ipomopsis aggregata. I found that both clipping and adding nutrients influenced pollen receipt. Pollen receipt was highest in unclipped plants given fertilizer treatments. There was also a temporal effect on pollen receipt of conspecific pollen in unclipped plants. Pollen receipt decreased as the season progressed. As this paper is a study of the indirect effects of herbivory and nutrient variation on plant reproduction, it raises questions about the influence of herbivory and varied nutrients on plant reproduction, aside from seed production and other direct effects.
