Dr. Griswold's research relates to the systematics, biogeography, and biodiversity of native bees in support of the research unit's efforts to diversify available crop pollinators and conserve pollinator populations. Systematics research focuses on Megachilidae, the family with the greatest potential for manageable pollinators. Biodiversity and biogeography research, in collaboration with Federal land managers, provides the opportunity to develop an understanding of floral preferences among bees and spatial patterns in bee communities while providing managers with inventories and baseline data for monitoring pollinators. Faunal studies have been conducted in nine National Parks and Monuments. Responsibilities also include curation of the U.S. National Pollinating Insects Collection, a worldwide collection ov over a million specimens, and the associated specimen database and reprint collection.
