Crop domestication: anthropogenic effects on insect-plant interactions in agroecosystems

Abstract

Although crop domestication is considered a model system for understanding evolution, the eco-evolutionary effects of domesticated crops on higher trophic levels have rarely been discussed. Changes in size, shape, quality, or timing of plant traits during domestication can influence entire arthropod communities. The plant traits specific to crop plants can be rare in nature. In the face of such novelty, it is important to understand how species and trophic levels vary in their responses. Although the evidence is still limited, crop domestication can influence the ecology, genetics, and evolution of plants, insect herbivores, natural enemies, and pollinators. We call for more study on how eco-evolutionary processes operate under domestication to provide new insight on the sustainability of species interactions within agroecosystems.
