Abstract: | On the basis of studies on the ecology of boreal bat species in the Southern Urals (1997–2004), the first classification of their summer habitats has been made. It has been shown that spatial segregation of sex groups into areas of two types, designated wintering and breeding zones, takes place in populations in the period of offspring rearing. In females, seasonal migrations are guided by imprinting on sites providing sufficient food for offspring rearing and on wintering sites. In males, imprinting on wintering sites alone is observed. |
