Plant-aphid systems provide a valuable opportunity for studying the ecological consequences of land use change for interacting species. The North American tallgrass prairie has undergone severe reduction and fragmentation due to agricultural development. The prairie perennial Echinacea angustifolia, a model system for studying population-level effects of habitat fragmentation, hosts a specialist ant-tended aphid (Aphis echinaceae). My research explores various aspects of the relationship between aphids and Echinacea to evaluate consequences of habitat fragmentation for plant and aphid populations.
