Roads potentially impact nearly one-fifth of the continental United States. Runoff, traffic disturbance, and maintenance associated with roads can affect both the abiotic and biotic features of roadside ecosystems. Species along unpaved roads are particularly susceptible to road dust effects. Plant physiology, such as gas exchange and overall productivity, is found to deteriorate in increased dust conditions. However, few studies have examined how dust influences plant reproduction. In this study, I examined how road dust impacts pollen delivery, pollen adhesion, and the translation of pollen to seed in Rocky Mountain populations of Ipomopsis aggregata. However, no stage of reproduction in I. aggregata was correlated with different dusting treatments, perhaps because visitation rates and pollen loads were high from high levels of pollinator activity. This study highlights the importance of temporal variation in future studies of road dust effects on plant reproduction.
