Evolution of Optimal Group Attack, with Particular Reference to Bark Beetles (Coleoptera: Scolytidae)

摘要: A general model for the benefits and costs of group attack by small predators that kill large prey was developed, provided support hypothesis bark beetles infesting pine trees have evolved behavior maximizes individual fitness. The also provides a basis evaluating conditions under which social hunting is likely to evolve, insights on population dynamics animals hunt in groups. See full-text article at JSTOR
