The structure of plant-pollinator mutualistic interactions is important for pollination network stability and robustness in the face of environmental change. Even slight changes in seasonal or annual precipitation patterns (e.g., drought) can disrupt the critical plant-pollinator mutualisms that comprise healthy pollination systems, primarily through changes in the availability of floral resources. Increased instances of drought across regions, especially in the southwestern United States, is a likely threat to plant and pollinator species richness, phenology, and mutualistic associations. In this paper, we evaluate the impacts of short-term drought on the plant-pollinator communities of the San Francisco Peaks in northern Arizona. Specifically, we evaluate how plant and pollinator species abundance, richness, mutualistic interactions, and degree of pollinator generalization differed between a “wet year” (2017) and “dry year” (2018) on the San Francisco Peaks, and how these shifts may be further impacted at three different life zones (elevation zones). We determine that that plant richness and abundance decreased in the dry year, and overall pollinator species generalization increased in the dry year, with a larger number of species considered to be “core generalists”. Additionally, the timing of plant and pollinator activity periods were less consistent in the dry year; there was delayed blooming for many floral resources until after monsoon rains began, and insect activity tended to start and continue later in the season for all life zones. Finally, at the highest life zone Spruce Fir, over half of the pollinator species that foraged during both years showed increases in their total plant partners in the dry year. Increased pollinator generalization for some species in the dry year, despite fewer floral resources, may suggest some degree of plasticity when it comes to partner choice, which may be buffering this local pollination system from community collapse when resources are scarce, especially at higher elevation communities. With changing climate, uncovering which pollinator species and plant-pollinator associations are most critical for local community stability in drought conditions is important for understanding pollination network structure and informing conservation decisions on local scales.
