Natural Movements of Tagged Beavers in Tyva

Natural Movements of Tagged Beavers in Tyva Ninety-three beavers were tagged in 1998–2000 on the Azas River (Tyva Republic), and 28 returns were obtained within one to two years. The results of the study indicated that, unfavorable environment notwithstanding, most beavers did not move outside their settlements. Animals under two years of age were especially active. Females were more resident, whereas males migrated over longer distances.

Abstract

Ninety-three beavers were tagged in 1998–2000 on the Azas River (Tyva Republic), and 28 returns were obtained within one to two years. The results of the study indicated that, unfavorable environment notwithstanding, most beavers did not move outside their settlements. Animals under two years of age were especially active. Females were more resident, whereas males migrated over longer distances. The section of the Azas River with numerous rapids was not an insuperable obstacle for the animals; genetic exchange between the upper and lower subpopulations was found to occur through this section.
