Pollen plays a key role in plant reproductive biology. Despite the long history of research
on pollen and pollination, recent advances in pollen‐tracking methods and statistical
approaches to linking plant phenotype, pollination performance, and reproductive fitness
yield a steady flow of exciting new insights. In this introduction to the Special Issue
“Pollen as the Link Between Phenotype and Fitness,” we start by describing a general
conceptual model linking functional classes of floral phenotypic traits to pollinationrelated
performance metrics and reproductive fitness. We use this model as a framework
for synthesizing the relevant literature, highlighting the studies included in the Special
Issue, and identifying gaps in our understanding and opportunities for further
development of the field. The papers that follow in this Special Issue provide new
insights into the relationships between pollen production, presentation, flower
morphology, and pollination performance (e.g., pollen deposition onto stigmas), the
role of pollinators in pollen transfer, and the consequences of heterospecific pollen
deposition. Several of the studies demonstrate exciting experimental and analytical
approaches that should pave the way for continued work addressing the intriguing role of
pollen in linking plant phenotypes to reproductive fitness.
