Ecology of Urban Street Tree Herbivores
As ectotherms, insects are especially sensitive to temperature, including urban heat islands. We are examining the consequences of this warming for urban herbivores and their host trees. Thus far, we have found that scale insect pests are most abundant in hot urban sites, where they damage street trees and compromise the ecosystem services trees provide. Additionally, our most recent studies of the responses of arthropods to warming across an urbanization gradient at broad geographic scales suggest that urban warming may be a canary in the coal mine for global climate change, as insects respond similarly to urban and global warming.
