| Outline of Final Research Achievements |
Pollinator shifts has been considered an important evolutionary events for the ecological speciation of plants, but is uncertain how it progresses under what kind of environment. Melampyrum macranthum which distributed in the southern part of Kii peninsula and have long flower tube was pollinated by diurnal hawkmoth although other Melampyrum species was mainly pollinated by long-tongued bees. On the other hand, M. laxum var. yakusimense which distributed in the Yaku Is. and have short flower tube was mainly visited by syrphid flies. These two taxa are closely related in M. laxum which pollinated by long-tongued bees, but these bees were not confirmed in the locality of the both taxa through anthesis. It is thought that both taxa were evolutionarily adapted to nectar or pollen robber of M. laxum under environment having few long-tongued bees.
