Description
Summary:Growth rate, reproductive characteristics, and survival rate of European water voles taken from the population at the peak, decline, depression, and increase phases of population cycle were compared under standard vivarium conditions. In November to March, the growth rate of decline-phase males was higher, while that of decline-phase females was lower than in other animals. Decline-phase males were also more successful in reproduction than males taken at other phases. The survival rate of decline-phase females was reduced in the winter period.
