Microhabitat selection by three small mammal species in oak-elm forest

摘要: Between 1996 and 1998, microhabitat selection by three small mammal species was studied in oak-elm forest using the catch-mark-release (CMR) method. Microhabitat these assessed Discriminant Function Analysis (DFA) Canonical Correspondence (CCA). Apodemus flavicollis shown to prefer dense young shrubs, but presence of dead woody material also important. In Microtus arvalis data confirmed a negative relationship with stands higher tree shrub cover preference for open meadows. Clethrionomys glareolus found non-fragmented microhabitats, preferring sites developed undergrowth ample hiding places amongst fallen logs branches. Although C. did not change its requirements during year (spring autumn), within it connected regardless composition; this highlights importance glareolus. Seasonal changes could be unambiguously.
