Overview

Long-term study reveals that post-fire ecological succession generates fluctuating pollinator selection in Lapeirousia anceps, indicating that fire cycles sustain floral diversity.

Key Points

  • To examine how post-fire succession and temporal environmental variation alter pollination niches to maintain floral polymorphism within a plant population.
  • Conducted a long-term field study tracking pollination niches and floral phenotypes across post-fire successional stages in Lapeirousia anceps.
  • Evaluated the impact of temporally changing pollinator assemblages on phenotypic selection within a single population.
  • Predictable post-fire successional changes systematically altered pollination niches over time.
  • Temporal environmental variation generated fluctuating selection regimes that sustained two distinct floral morphs without leading to speciation.
