Tiger cubs from litters of five or more have nearly double the mortality risk compared to single or twin cubs in the same habitat.
Tiger litters can range from one to seven cubs, but survival probability decreases with size. In large litters, mothers may struggle to provide enough milk and attention for all cubs. Competition among siblings can lead to weaker individuals being neglected or displaced. Predation risk is also higher in large litters because mothers must split time and resources. Official survival statistics may obscure the impact of litter size by focusing on overall juvenile numbers. Cubs in smaller litters tend to grow faster, develop stronger immune systems, and have higher survival rates. Environmental stressors such as prey scarcity or habitat degradation exacerbate mortality in large litters. Understanding litter size effects informs breeding programs and population modeling. Early-life survival is thus sensitive to both biological and ecological factors.

Litter size influences population recruitment and resilience. Conservation planning must account for maternal capacity to raise multiple cubs. Transparent reporting of litter-specific survival improves population projections. Large litters require higher-quality habitats to ensure juvenile success. Cubs’ survival reflects both maternal investment and environmental sufficiency. Protecting habitat quality can mitigate natural disadvantages in larger litters. Early-life competition shapes demographic outcomes for predator populations.
Monitoring litter outcomes guides adaptive management in both wild and captive settings. Understanding the interaction between litter size, resource availability, and juvenile survival informs reserve design. Transparent data collection ensures realistic assessment of population viability. Cubs are biological indicators of maternal health and habitat adequacy. Conservation interventions can prioritize at-risk litters to maximize recruitment. Maintaining ecosystem productivity is critical to offset challenges in large litters. Litter variability is a hidden but powerful determinant of cub survival.
