The Impact Of Climate Change On The Mistiming Of Bird-Resource Phenologies

Main Article Content

Joseph Funk


As the climate continues to warm, phenologies of organisms across a variety of taxa are continuing to change. These changes are resulting in potential mismatches in resource acquisition. Specifically, migratory birds are experiencing population declines as a result of their food resources emerging at different times in their breeding grounds. I have shown how these food-timing mismatches are resulting in population declines in a range of migratory bird species, from passerines to shorebirds to hummingbirds. A failure to match their migration timing with resource availability in breeding grounds could result in significant population declines in migratory birds.

Joseph Funk

Joe Funk is a first year M.S. student in the Biology Department studying the impacts of climate change on invasive vs. native plant community dynamics. He received a B.S. in Ecology and Evolutionary Biology from the University of Connecticut, where he conducted prior research modeling the species distribution of garlic mustard, an invasive herb in the eastern United States. During his undergraduate career he spent time in Australia and New Zealand conducting rainforest restoration. In the future Joe plans to continue to advance our knowledge of the implications of climate change on ecosystem services.
