| Research Abstract |
Natural hybridization is not a rare phenomenon in plants. Interspecific hybridization is expected to occur in contact zones where two parental species co-occur. However such contact zones may not be similar in environmental condition, leading to different evolutionary consequences because the different environmental conditions likely influence the fitness of the individuals originated from natural hybridization even between the same species pairs. In this study, I addressed the question if natural hybridizations between the same species in different habitats lead to different evolutionary consequences. In a few hybridizing species pairs examined, gene flow patterns between the species were largely different among the populations. The patterns in phenotypic constitution in populations were also largely different among the populations. These differences may suggest that the hybridization between the different habitats results in different evolutionary consequences.
