Research overview: cub survival and the creche system in lions

Lion cub survival is shaped by the communal creche, in which synchronously breeding females pool and defend their young. This overview surveys research on how creche formation buffers cubs against starvation through allonursing and against infanticidal males through collective defence, how reproductive synchrony arises, and the high baseline cub mortality from predation, starvation, and takeovers. It discusses how creche membership and pride size influence which cubs survive to independence. It connects cooperative cub rearing to the broader evolution of lion sociality. The topic explains why communal rearing is central to female reproductive strategy and to the demographic resilience of prides.
