| Abstract: | The distribution of Brandt's vole were aggregated in the whole year except the initial breeding period. During that period, the voles were randomly distributed, and the females showed an increasing competitive trend for living space. The females had a strong attraction to the males,especially in the reproduction season. The observed proportion that males selected females as the nearest neighbours was higher than the expected one, but not significantly. The males had a strong attraction to the females in the non-reproduction season. The population showed an aggregated tendency before the reproduction season,a dispersal tendency from non-reproduction to reproduction season, an aggregated tendency again after the reproduction season. |
