NOTES ON THE STUDIES OF VARIATIONS IN THE NUMBERS OF THE BANK VOLE (MYODES GLAREOLUS SCHR.) IN THE NORTHERN PERIPHERY OF THE SPECIES RANGE
We analyzed long-term (1958–2017) data on variations in the numbers of the bank vole (Myodes glareolus Schr.) in Eastern Fennoscandia, which is the northern periphery of the species distribution range. The species abundance under these conditions is relatively low compared to the optimum range (1.9...

We analyzed long-term (1958–2017) data on variations in the numbers of the bank vole (Myodes glareolus Schr.) in Eastern Fennoscandia, which is the northern periphery of the species distribution range.
