Distribution under climate change of Anemone coronaria: linking flower colour and seed dispersal

Nordic Journal of Botany, EarlyView.
Flower colour polymorphism is driven by divergent selection regimes on the colour morphs across time and space. Anemone coronaria, a colour‐polymorphic geophyte with red, purple, and white flowers, displays a geographic pattern along Israel's aridity gradient: polymorphic populations are restricted to Mediterranean climates, while monomorphic‐red ...
