The evolution of floral traits is often considered to reflect selection for increased pollination
efficiency. Known as the pollination‐precision hypothesis, increased pollination efficiency is …

Natural selection should reduce phenotypic variation and increase integration of floral traits
involved in placement of pollen grains on stigmas. In this study, we examine the role of …

Pollinator-mediated stabilizing selection (PMSS) has been proposed as the driver of the
evolutionary shift from radial to bilateral symmetry of flowers. Studies have shown that …

Aquatic Dicotyledons of North America (Les, 2017) and follows a similar format by providing
a comprehensive overview of the life history, ecology, and systematics of those …

Background and Aims The pollinator-mediated stabilizing selection hypothesis suggests that
the specialized pollination system of zygomorphic flowers might cause stabilizing selection …

Flower size is a key trait in the reproductive ecology of animal-pollinated plants. However,
pollinator-mediated selection does not always modulate this trait and environmental …

The multiple evolutionary transitions from radial to bilateral flower symmetry recorded across
the angiosperms have been related to pollinator specialization and the promotion of …

PREMISE OF THE STUDY: The evolutionary shift from radial to bilateral symmetry in flowers
is generally associated with the evolution of low flower‐size variation. This phenomenon …

Floral integration may result from the combined effects of pollinator-mediated selection,
genetic correlations and abiotic factors. Thus, by sampling a set of populations in the field …

Andromonoecy, the presence of perfect and staminate flowers in the same individual, has
evolved repeatedly in angiosperms. The staminate flowers are generally smaller than the …
