摘要: House mouse Mus domesticus populations in Australia can occur at either low or very high densities. During a 2-yr study mice increased from rarity to abundance two phases: phase A reached medium densities and declined, B they before declining near extinction. We hypothesise that were regulated by predators A, but escaped regulation form plagues B. measured directly the mortality imposed raptors mammalian predators. Two predictions tested: (1) if regulate prey then predator total response shoud be density-dependent within range of (phase A); (2) when outbreak occurs B) should inversely
