In some isolated tiger reserves, up to 20% of cubs fail to survive due to congenital or genetic weaknesses linked to inbreeding.
In isolated tiger reserves, low genetic diversity increases the likelihood of congenital defects, weakened immunity, and higher susceptibility to disease. Cubs born in genetically bottlenecked populations often fail to thrive, even when maternal care is adequate. Official surveys rarely incorporate genetic health into population estimates, focusing instead on adult numbers. Genetic vulnerabilities may lead to higher neonatal mortality, delayed growth, or behavioral anomalies that reduce survival. Fragmentation further prevents gene flow, compounding the problem over generations. Conservation programs increasingly rely on genetic monitoring to identify at-risk populations and guide breeding. Even resilient adults may mask these hidden juvenile losses. Understanding genetic bottlenecks is essential for predicting true population viability. Early-life survival is both a biological and genetic indicator of long-term species resilience.

Protecting genetic diversity directly supports cub survival and population growth. Facilitating gene flow between reserves reduces inbreeding depression. Transparent monitoring of genetic health allows for realistic population management. Genetic bottlenecks amplify vulnerability to disease, environmental stress, and reproductive failure. Juvenile mortality due to genetic factors can be invisible in standard census data. Incorporating genetics into conservation planning ensures healthier, more resilient populations. Cubs are living indicators of genetic robustness and ecosystem health.
Translocation and managed breeding can mitigate genetic bottlenecks and reduce cub mortality. Genetic assessments help prioritize conservation actions in isolated reserves. Monitoring neonatal survival reveals hidden population vulnerabilities. Integrating genetics with demographic and ecological data improves long-term population forecasts. Protecting early-life stages ensures adult counts reflect true reproductive success. Cubs carry the legacy of genetic diversity for future generations. Understanding these hidden risks is vital for effective predator conservation.
