Research overview: female reproduction and cub-rearing in tigers

Tigress reproduction is shaped by the energetic challenge of raising cubs alone over nearly two years. This overview synthesizes studies on litter size, cub survival, the long period of maternal dependence, and the interval between litters, showing that a tigress invests heavily in a few offspring and cannot breed again until her current cubs approach independence. It reviews how prey abundance, the security of her territory, and the threat of infanticide by new males influence reproductive success, and how cubs learn to hunt during an extended apprenticeship. The synthesis connects individual reproduction to the slow population growth characteristic of the species. For enthusiasts it explains why tigress territories must be rich enough to feed a growing family, why litters are spaced years apart, and why the loss of a breeding female is so costly to a population.
