Research Interests
Dr. Inouye has worked with bumblebees, euglossine bees, pollinating flies, tephritid flies, hummingbirds, and wildflowers, on topics including pollination biology, flowering phenology, plant demography, and plant-animal interactions such as ant-plant mutualisms, nectar robbing, and seed predation. He has worked in Australia, Austria, Central America, and Colorado, where he has spent summer field seasons since 1971 at the Rocky Mountain Biological Laboratory (RMBL). His long-term studies of flowering phenology and plant demography are supported by the National Science Foundation and are being used now to provide insights into the effects of climate change at high altitudes.
Dr. Inouye taught courses in ecology and conservation biology at the University of Maryland, and has also taught at the University of Colorado's Mountain Research Station, the Rocky Mountain Biological Laboratory, and with the Organization for Tropical Studies. He is the founder and moderator for the Ecological Society of America's ECOLOG-L listserv list, and serves on the Board of the North American Pollinator Protection Campaign. He is Past-President of the Ecological Society of America, and a Lead Author on the report on pollinators produced by the Intergovernmental Platform on Biodiversity and Ecosystem Services.
