Effects of Climate Changes on Ecologically Important Bees and Flowers
Abstract
Climate warming affects the phenology, abundance and distributions of plants and pollinators. Despite this, there is still limited knowledge on how temperature affects plant- pollinator mutualisms. The ongoing project with Dr. Rebecca E. Irwin in collaboration with David Inouye has been gathering data at the Rocky Mountain Biological Laboratory (Colorado, USA). We are studying bee phenology and abundance, and flower phenology and abundance, and how those relationships have been changing over time as they are impacted by climate change. We have used historical data from 2009 - 2016 to determine if the increase in temperature causes phenological mismatches. Our results showed that flowers are reacting to temperature changes and may be blooming earlier, leaving a bee pollinator without food resources. Thus, bees are altering their flower visitations over the years and how flower abundance at any given site has been changing as well.
