Demography during a population crash of the wood lemming, Myopus schisticolor
Four-year microtine population density cycles are extreme in northern Fennoscandia. We studied populations of wood lemmings (Myopus schisticolor) and bank voles (Clethrionomys glareolus) in the peak phase and subsequent crash phase at two localities, Varaldskogen and Risberget, Norway. Bank voles at...
