Abstract/Summary

Effective pollination is a complex, context-dependent phenomenon determined by both species-level and community-level factors. While pollinator communities are constituted by interacting organisms in a shared environment, these factors are often simplified or overlooked when quantifying species-level pollinator effectiveness alone. Here, we review the recent literature on pollinator effectiveness to identify the pros and cons of existing methods and outline three important areas for future research: plant-pollinator interactions, heterospecific pollen transfer and variation in pollination outcomes. We conclude that pollinator community effectiveness needs to be acknowledged as a key property of pollination effectiveness in order to fully account for the suite of plant, pollinator and environmental factors known to influence different stages of successful pollination.
