Island tiger populations often have higher infant mortality than mainland populations due to both isolation and environmental unpredictability.
The Andaman Islands are home to fragmented patches of tropical forest that could once support larger predator populations. Isolated tiger populations here experience limited mate choice, which directly impacts cub survival over generations. Genetic diversity declines as inbreeding increases vulnerability to disease and congenital issues. Cubs born with subtle deformities or weakened immune systems often fail to survive their first year. Island storms can destroy dens and displace mothers searching for prey. Prey density is uneven, forcing tigresses to risk longer hunting trips and leaving cubs unattended. Conservation efforts focus on adult sightings, rarely capturing these nuanced early-life pressures. Over time, isolation transforms what seems like a thriving population into a fragile genetic experiment. These cubs are both literal and symbolic canaries in the forest.

Small island populations are inherently vulnerable to stochastic events. One storm, disease outbreak, or prey crash can erase a generation of cubs. Limited territory amplifies intraspecific competition, with older siblings sometimes dying due to maternal resource constraints. Even well-funded conservation programs cannot fully mitigate genetic bottlenecks without introducing new individuals. Age-specific survival monitoring becomes essential for realistic population forecasts. Without this, managers may overestimate recovery potential. Island isolation converts minor ecological fluctuations into demographic catastrophes.
Introducing genetic rescue initiatives is controversial but may become necessary to maintain long-term viability. Awareness of cub survival rates can drive policy support for such interventions. Protecting island forests also benefits endemic species, creating a cascading ecological effect. Transparency about early mortality strengthens trust between scientists, locals, and international conservation partners. For predators, tiny cubs carry outsized ecological and genetic significance. In these forests, the smallest tigers can determine the future trajectory of their species.
