Community structure and competitive dominance may be related to differences in phenology. By initiating colonies earlier, species such as Bombus vosnesenskii may maintain higher densities of workers and reduce nest site availability for later emerging ground-nesting species. Exploitative competition in this study system may account for the pattern of species persistence and colony reproduction. This research will provide data for numerous California bumble bee species, many of whose ranges extend into other states. With recent declines in several Bombus species and research suggesting that climate change may result in mismatch phenological shifting between flowering plants and their pollinators, data on emergence and community structure of Sierra Nevada bumble bees is greatly needed.
