A test of phenotypic selection on petal form in the wild carnation, Dianthus inoxianus.

Abstract excerpt

Floral phenotypes are considered a product of pollinator-mediated selection, which also has the side effect of decreasing floral variation within species. Correlates of flower visibility and function were studied in a carnation species (Dianthus inoxianus), which has crepuscular anthesis and scent-based pollination by the hawkmoth Hyles livornica. We also assessed constancy of flower form in nature and in...
