Post-dispersal seed predation in the hedgerows of agroecosystems in southern Chile
ABSTRACT Agricultural ecosystems host a large variety of organisms that can contribute to weed control through seed consumption. However, seed consumption rates in the agroecosystems of southern Chile are virtually unknown. We experimentally evaluate oat seed consumption by birds, rodents and invert...
