Frequency-dependent variation in reproductive success in Narcissus: implications for the maintenance of stigma-height dimorphism.

Proceedings. Biological sciences - 7 May 2003

Thompson John D, Barrett Spencer C H, Baker Angela M

Abstract excerpt

Negative frequency-dependent selection is a major selective force maintaining sexual polymorphisms. However, empirical demonstrations of frequency-dependent reproductive success are rare, particularly in plants. We investigate this problem by manipulating the frequencies of style morphs in a natural population of Narcissus assoanus, a self-incompatible herb with style-length dimorphism and intra-morph...
