Major declines in pollinating insect species and the implications of climate change have greatly increased the relevance of pollination ecology research. This research is particularly important in alpine ecosystems, which are sensitive to the effects of climate change. Despite this, little work has been done concerning alpine plant-pollinator mutualisms. This thesis compares the current pollinator on the Beartooth Plateau, a unique alpine ecosystem on the Montana/Wyoming border, with a historical study done 40 years ago. Important characteristics of the pollinator network were ascertained via the collection of insect specimens, recording of visitation rates, and tracking the phenology of flowering plants. In addition to this, a new design of insect exclosure was developed to test the dependence of alpine plants on their pollinators, and compare this dependency with the historical study conducted 40 years ago. Statistical analysis revealed that there have been marked shifts in the characteristics of the pollinator network over the last 40 years. This includes complex Bombus species composition changes within pollinator guilds were complex, decreased pollinator capture rates, decreases in network nestedness, lengthening of plant flowering phenophase, and distinct diel visitation patterns. The exclosure design withstood the harsh alpine conditions, and showed that the reproductive success of representative alpine plants relies heavily on insect pollination, and has undergone some plant-specific changes over time. Our work advances understanding of decadal-level changes to alpine pollination networks during the 20th and 21st centuries and highlights certain areas of alpine pollination ecology that require further attention.
