Pollinator activity in an altitude gradient in alpine populations of Leontodon autumnalis var. taraxaci, and their effect on reproductive success

Plant reproductive success is depending on temperature and climate during growth season, pollinator availibility and visitation rate, and interactions among plants, e.g. competition for resources and facilitated pollinator attraction. Plants in alpine regions face even larger climatic constraints and may also suffer from pollination limitation because of decrease in available pollinators with altitude. By including abiotic conditions, mutualistic interactions (pollination) and population qualities in elevational gradient consisting of 21 populations of the obligate out-crossing, lateflowering species Leontodon autumnalis var. taraxaci (Mountain Hawkweed) I wish to find out which predictors explain the observed variance in reproductive success. The fieldwork was performed at southfacing slopes of Sandalsnut and Kvanjolnut, Finse, Ulvik municipality – Norway.
