The cost of reinforcement: selection on flower color in allopatric populations of Phlox drummondii.
Reinforcement is the process by which increased reproductive isolation between incipient species evolves due to selection against maladaptive hybrids or costly hybrid mating. Reinforcement is predicted to create a pattern of greater prezygotic reproductive isolation in regions where the two species co-occur, sympatry, than in allopatry. Although most research on reinforcement focuses on underst...
متن کاملMolecular signatures of selection on reproductive character displacement of flower color in Phlox drummondii.
Character displacement, which arises when species diverge in sympatry to decrease competition for resources or reproductive interference, has been observed in a wide variety of plants and animals. A classic example of reproductive character displacement, presumed to be caused by reinforcing selection, is flower-color variation in the native Texas wildflower Phlox drummondii. Here, we use popula...
متن کاملMeasuring selection and gene flow during reinforcement
Gene flow can impede the evolution of reproductive isolating barriers between sympatric species. Reinforcement is the process by which pre-zygotic reproductive isolation evolves in sympatry due to selection to decrease costly hybridization. It is known that reinforcement can be prevented by too much gene flow, but it is unknown the extent to which reinforcement has naturally evolved in the pres...
متن کاملStrong Reinforcing Selection in a Texas Wildflower
Reinforcement, the process of increased reproductive isolation due to selection against hybrids, is an important mechanism by which natural selection contributes to speciation [1]. Empirical studies suggest that reinforcement has generated reproductive isolation in many taxa (reviewed in [2-4]), and theoretical work shows it can act under broad selective conditions [5-11]. However, the strength...
متن کاملPollinator-mediated selection on flower color allele drives reinforcement.
Reinforcement is the process by which reduced hybrid fitness generates selection favoring the evolution of stronger prezygotic reproductive barriers between emerging species. Using common-garden field experiments, we quantified the strength of reinforcing selection in nature by demonstrating strong selection favoring an allele conferring increased pigment intensity in the plant Phlox drummondii...
