Exploring multitrophic interactions in oilseed rape fields reveals the prevailing role of Carabidae

Abstract In cropped fields, birds are often at the highest position in the food chain, feeding on pest arthropods and their intermediate predators in a process known as intraguild predation. The net effects of bird predation on phytophagous insect populations (feeding on plants) are difficult to pre...
