LANDSCAPE LEGACY AND URBAN AGRICULTURE: UNDERSTANDING THE IMPACT OF HEAVY METAL CONTAMINATION ON POLLINATOR HEALTH AND POLLINATION SERVICES

Project Summary: Cleveland OH’s formerly densely-populated inner-city neighborhoods now contain over 27,000 vacant lots as a result of protracted economic decline and the recent home foreclosure crisis. Currently, there are over 250 urban agroecosystems established on formerly vacant land across Cleveland. The sustainability of urban agriculture requires reliable ecosystem services, including pollination. A landscape legacy of heavy metal (HM) soil contamination represents a key threat to pollinators. We propose to study the impact of HM contamination on bee foraging behavior, bumblebee colony health, and pollination. Our work will begin by examining how soil HM contamination influences bee visitation and pollination services of focal crop plants (Objective 1). Next, we will focus on how foraging on contaminated provisions influences colony health, including reproductive potential, nutritional state, immunity, and detoxification (Objective 2). Third, we will track individual pollinators throughout an urban agroecosystem to determine how HM exposure influences their overall foraging patterns and efficiency (Objective 3). Finally, we will determine the weedy flora that provide key resources for pollinators and identify how these plants vary in their concentration of HM (Objective 4). In accomplishing our objectives, we will elucidate the effects of HMs on a vital ecosystem service necessary to attain sustainability and security in urban agriculture.

Chris Riley Recognized for Service

Graduate Student Chris Riley was recently recognized with the Department of Entomology David J. Horn Service Award for 2017 at the annual department picnic. Chris volunteers at many outreach events on campus each year, holds a large number of professional service positions, and is an avid volunteer in our community. Congrats Chris!
