Data from: Indirect food web interactions mediated by rodent cycles: relative roles of lemmings and voles
Production cycles in birds are proposed as prime cases of indirect interactions in food webs. They are thought to be driven by predators switching from rodents to bird nests in the crash phase of rodent population cycles. Although rodent cycles are geographically widespread and found in different ro...
