Abstract:

Examined population fluctuations of the voles Microtus agrestis and Clethrionomys glareolus, black grouse Lyrurus tetrix, mountain hare Lepus timidus and red fox Vulpes vulpes. Synchronous population fluctuations between voles as a group and the other species conformed to a 3-4 yr periodic pattern in both autumn and spring populations only in northern and central Sweden (the boreal forest region). Spring populations of boreal forest grouse, hare, and probably also fox, lagged 1 yr behind the voles. The northerly areas also formed geographical units of co-fluctuation within each game species. The synchronizing link between the herbivores could be 1) food plant quality and/or quantity and/or 2) predation.
