摘要：

Some populations of animals undergo dramatic cycles in which the numbers vary considerably, and the causes of such cycles have long been debated. Two long-term, large-scale experiments on red grouse in Scotland and voles in Finland conclude that the respective agents of population crashes in these cases are a parasitic nematode and predator pressure.
