Animals pollinate most of the world’s flowering plant species including most crop plants. Yet pollinators are threatened by global environmental changes such as increasing human land use and climate change. My work integrates approaches from pollination biology, landscape ecology, and biodiversity-ecosystem functioning research to investigate how pollinators and the ecosystem services they provide can be maintained in human-dominated ecosystems. Dr. Winfree focuses on agricultural systems, because they both drive global biodiversity loss, and rely on the ecosystem services pollinators provide.
