The role of habitat isolation in formation of structure and dynamics of the bank vole population

Examination was made of variations in numbers, rate of exchange of individuals, sex structure and sexual activity, trappability and spatial organization of a local population of bank voles, Clethrionomys glareolus (Schreber, 1780), inhabiting an isolated patch of wooded land forming a habitat island. The results obtained were compared with analogical results for an control open population. The animals were trapped in live-traps, using the CMR method from 1977-1979 in three 10-day series in each calendar year (spring, summer, autumn).
