dc.description.abstractThe plant-pollinator mutualism can be disrupted in isolated populations. This relation also critically affects directional selection on floral traits. Isolated plant populations may attract fewer and less diverse pollinators, and plants may compete for pollination within the population and with other co-flowering plant species , possibly selecting for increased number of flowers in the floral display. In this thesis, I characterized the major pollinators of Plectritis congesta ( or Sea blush), to study the effects of isolation on the Gulflslands and Vancouver Island. I found that: (1) site connectivity is a major determinant of the pollinator assemblage; (2) population density is correlated with floral display, visitation rates, and possibly pollinator assemblage, whereas competition from co-flowering species is not; and (3) both floral display and geographical elements that control pollinator abundance and composition influence the potential for selfing, and pollinator composition could impose selection for increased floral display in isolated populations.
