title: Vole cycles and antipredatory behaviour.
abstract: During recent years the role of predation as a simple mechanism to produce cyclical population fluctuations in microtine rodent populations has gained stronger empirical and theoretical support. Predation by several generalist species produces non-cyclicity, and predation by resident specialists, such as small mustelids, produces a synchronous cyclic pattern of population fluctuations in several vole species. At the same time, behavioural ecological studies have shown that the same group of specialist predators crucial for cyclicity causes the strongest antipredatory responses in vole behaviour. Recently, breeding suppression in cyclic microtines under risk of mustelid predation has been documented both in the laboratory and in the field. This review links the new population ecological studies and modelling of cyclic microtines and their predators with recent findings on antipredatory adaptations of voles.
