| Research Abstract |
A native annual herb, Veronica polita lilacina, has been known to be found at crevice of stone walls. In this study, I showed that the inter-specific pollination from the allied alien species, V. persica, decreased the seed-set of the natives and this caused the decrease of the natives, that the original habitat of the natives was on the ground and that the seed-dispersal mutualism with a diverse ant species helped to alter the habitat to the stone wall environment based on experiments and field surveys among islands in the Seto Inland Sea.
