Research overview: communal denning and creche formation in lions

Lionesses that give birth around the same time pool their cubs into a communal creche, nursing and defending young cooperatively. This overview surveys how creches form following synchronized births, how females allow cubs other than their own to suckle, and how communal care improves cub survival against infanticidal males and predators. It reviews the kin structure that makes such cooperation favorable, since pride females are typically close relatives. The review considers how creche dynamics affect the distribution of milk and the survival of cubs from different mothers. Communal denning is a defining feature of lion reproduction that distinguishes the species from solitary felids and links social structure directly to reproductive outcomes.
