Breeding in The Wild - Mammals

Mammals

Annual breeding cycles sometimes apply to mammals, with regulating environmental effects including seasonal temperature variation and food availability. Migration patterns of a mammal may sometimes govern breeding times. Mammal breeding in the wild sometimes the use of maternity dens for birthing and protection of the young. The Polar Bear is an example of a mammal who uses a maternity den, whose locations are influenced by migration movements of this species to the seasonal Arctic pack ices. In particular the Polar Bears who breed in Wapusk National Park need to migrate to the Hudson Bay pack ice.
