Synchronous short‐term population fluctuations of some birds and mammals in Fennoscandia ‐ occurrence and distribution
We examined population fluctuations of the voles Microtus agrestis L. and Clethrionomys glareolus Schreb. by biannual trapping; black grouse Tetrao tetrix L., mountain hare Lepus timidus L., and red fox Vulpes vulpes L. by using bag records from all over Sweden, questionnaires from south‐central Swe...
