In recent years, a loss of insect pollinators has raised concerns over adequate supply of pollination services to crops and wild plants. A key priority is understanding how pollinator biodiversity and pollination services respond to land-use change, such as the rapid growth of urban areas. Our project will work at urban farms throughout Chicago (including the Windy City Harvest Farms of Chicago Botanic Garden)to (1) document how pollinator biodiversity varies across farms; (2) measure real-world pollination services delivered to crops on these farms; and (3) whether the addition of flower gardens can restore lost pollination services. The REU student will work with their mentor to develop a project within the context of this system to examine how insect pollinators such as bumble bees or butterflies use urban farms throughout their life cycles. The student will gain valuable skills in ecological fieldwork, insect and plant identification, horticulture, urban habitat restoration, and community outreach. The student must have an interest in handling insects and the willingness and patience to spend long days outside.
