摘要: Two populations of the meadow vole, Microtus pennsylvanicus , one inhabiting an abandoned field, other a grass-sedge marsh, were live-trapped at monthly intervals from September 1957 through 1958. The mean home range size males was larger than that females in both areas. ranges marsh those old field; there no difference between sizes two varied inversely with population density. Environmental conditions particularly low winter temperatures, exerted more influence upon did data indicate M. displays territorial behavior. degree such behavior does not appear to be influenced by density or environmental conditions. About 20 per cent shifted their each month. A greater percentage moved females. young voles displayed only slightly tendency move adults.
