研究了来自斯瓦尔巴群岛Grumantbyen的田鼠种群的6个个体和来自荷兰Lauwersee的6个田鼠Arvalis（Pallas 1778）的染色体。 结果表明，来自斯瓦尔巴特群岛的田鼠并不像以前所认为的那样属于M种。arvalis（2n = 46），但对M. epiroticus（Ondrias，1966）（2n = 54）。 我们认为，斯瓦尔巴德田鼠介绍了1920年和1960年之间的人一起从苏联列宁格勒附近的俄罗斯船只上的干草。
The chromosomes were studied in six individuals from a population of Microtus from Grumantbyen, Svalbard, and in six Microtus arvalis (Pallas 1778) from Lauwersee, Holland. It was shown that the voles from Svalbard did not belong, as earlier supposed, to the species M. arvalis (2n = 46) but to M. epiroticus (Ondrias, 1966) (2n = 54). We suggest that the Svalbard voles were introduced by man between 1920 and 1960 together with hay on Russian ships from the vicinity of Leningrad, USSR.
