Flowering plants show wide variation in the proportion of fertilized ovules that mature into
seeds within individual fruits (9-11, 20, 39, 42, 44, 50, 74, 76, 77, 123). In most species a …

Bateman's principle states that male fitness is usually limited by the number of matings
achieved, while female fitness is usually limited by the resources available for reproduction …

The effects of corolla size, pollen production, and pollinator visitation frequency on pollen
removal (an estimate of male reproductive success) and pollen deposition and seed …

Evidence of pollen and/or resource limitation of seed production in the herbaceous
perennial plant Polemonium foliosissimum was investigated. Large numbers of open flowers …

Fruit production in interoparous flowering plants can be limited by a variety of conditions that
need not be mutually exclusive nor immediately evident. We examined short—and long …

As plant populations decrease in size, reduced seed set may contribute to their ultimate
extirpation. In this study, effects of pollen quantity and compatibility relationships (quality) on …

This study describes the interaction between Hormathophylla spinosa, a crucifer shrub, and
its pollinators, analyzing the spatiotemporal variability of the pollinator assemblage as well …

We explored the combined effects of seasonal variation in both pollinator assemblage and
availability of pollen donors on pollination in a gynodioecious species, Sidalcea oregana …

Seed production of a flower depends both on the quantity of pollen received and on its
quality as manifested in rates of germination, ovule fertilization, and seed maturation …
