[Seasonal variation in hematological indices in bank vole (Clethrionomys glareolus) in different reproductive states].

Hematological and hematopoietic indices were studied in various seasons in bank vole in different reproductive states. The seasonal variation in the indices demonstrated patterns typical of each state and reflecting the adaptive response to changed habitat conditions.

[Annual variation in hematological indices in a fluctuating population of bank vole (Clethrionomys glareolus)].

The quantitative and structural hematological indices were studied in bank vole in different reproductive states (overwintered individuals, mature underyearlings, and immature underyearlings) in different years corresponding to different phases of the population cycle. The annual changes in certain hematological indices have been revealed for each reproductive state irrespective of the population cycle phase.
