Spatial synchrony in vole population fluctuations- a field experiment

Article Abstract:

A field experiment was conducted in western Finland to evaluate the relative roles of three mechanisms in inducing spatial synchrony among cyclic populations of field voles Microtus agrestis. The results revealed that no single mechanism could account for the observed patterns of spatial synchrony among cyclic northern vole populations.

Predator-induced changes in population structure and individual quality of Microtus voles: a large-scale field experiment

Article Abstract:

Studies indicate a relative lack of high quality food at population peaks. The indirect effects of vole-eating predators on the population growth of main prey are found to be small when compared to the detrimental effects on prey survival.

Habitat composition as a determinant of reproductive success of Tengmalm's owls under fluctuating food conditions

Article Abstract:

The effects of habitat composition on the breeding success of vole-eating Tengmalm's owl were studied over six years. The strongest landscape effects were found in the decrease phase of the vole cycle.
