Examining the effects of multiple components of pollen deposition (varying according to quantity, source and timing) and pollen removal on key floral traits in Sabatia angularis, Spigler demonstrates the highly modulated responses of floral display and longevity to pollen deposition.
Longevity is shown to be influenced by the timing and amount of pollen deposited, but not affected by the source or removal of pollen, with implications for fitness. The study highlights the complexity of proximate factors shaping the plasticity of key floral traits, which govern successful pollinator attraction.
