Research Interests : Ecology and Conservation Biology (pollination biology, plant demography, climate change biology, flowering phenology, plant-animal interactions)

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 being used now to provide insights into the effects of climate change at high altitudes.
