摘要：

Intensive live-trapping over four summers revealed that neither population density nor season (early or late growing season) affected the home-range size of singing voles. Home-range size increased with body size for both sexes, and males generally had larger home ranges than females (average areas of 1,250 and 450 m2 for adult males and females, respectively). Seasonal patterns of overlap for reproductive animals suggested that singing voles have a promiscuous mating system and that territorial behavior is flexible (males tended to be territorial early in the breeding season and females tended to be territorial late in the breeding season). The construction of haypiles in August provided winter forage with higher protein content and occurred primarily in the home ranges of immature animals, the only cohort found to survive over winter.
