An isolated island population of field vole, Microtus agrestis L. has been investigated for allzyme variation. During the four‐year period of study, the population showed an aberrant demography, in comparison with the neighbouring mainland. The proportion of polymorphic loci was estimated to 44 % which is lower than on the mainland. A small excess of homozygotes was at hand, and significance was obtained only for males and when all loci were pooled. The average heterozygosity, H, calculated on a total of 18 loci was 0.19.
