* Population density: When tigers are densely packed, they are more likely to compete for resources, leading to fewer cubs surviving.
* Availability of prey: A lack of prey can stress tigers, leading to fewer births or even cannibalism of cubs.
* Habitat quality: Fragmented or degraded habitat can impact breeding success.
* Poaching and human conflict: These factors directly threaten tigers and their cubs.
Here's a breakdown:
* Gestation period: 93-110 days
* Litter size: 1-3 cubs, but usually 2
* Survival rate: Only around 50% of cubs survive their first year, often due to predation or starvation.
* Interbirth interval: 18-30 months, though it can be longer if a mother loses her cubs.
Overall, the reproduction rate of Bengal tigers is relatively low, meaning it takes time for populations to recover from losses.
It's important to note that these figures are estimates and can vary greatly. Conservation efforts are crucial for supporting Bengal tiger populations and increasing their reproduction rates.
