Weeds typically occur in patches of different sizes and densities. Post-dispersal seed predators contribute to biological weed control by removing newly produced weed seeds before they can enter the seedbank. Seed predation can limit weed population growth if seed predators respond to seed densities so that seed predation is highest within weed patches. To determine whether this relationship holds...
Seed predation can cause significant losses of weed seeds in agricultural systems and can, thus, contribute to weed control. The removal of Lolium multiflorum and Vicia villosa seeds by harvester ants, Messor barbarus, and granivorous rodents, Mus spretus, in six cereal fields in NE Spain was separated into three sequential processes, namely (1) the probability of finding a seed cache (cache encounter...
