We investigated the survival of cubs in a wild Indian leopard () population in the Jhalana Reserve Forest (JRF), India. The research focuses on analyzing the survival of leopard cubs during their first two years of life. Survival functions were estimated using the Kaplan-Meier method based on data collected with trail cameras over four years from 2018 to 2021. We found that the mean survival probability of cubs during the first year of life was 0.739, indicating that this period is particularly challenging for their survival. In the second year, the survival probability increased to 0.831, reflecting an improvement in survival as the cubs grew older. The combined survival rate over the two-year period, calculated as the product of the first- and second-year survival rates, was 0.618. These findings highlight the critical periods in the early life stages of leopard cubs, which are essential for developing effective conservation strategies in fragmented habitats to enhance their survival.
我们调查了印度斋拉纳保护区森林（JRF）中野生印度豹种群幼崽的存活情况。该研究重点分析豹幼崽出生后头两年的存活情况。基于2018年至2021年四年间用追踪相机收集的数据，采用Kaplan-Meier方法估计存活函数。我们发现，幼崽出生后第一年的平均存活概率为0.739，这表明这一时期对它们的生存尤其具有挑战性。在第二年，存活概率升至0.831，这反映出随着幼崽长大，其生存状况有所改善。两年期间的综合存活率，即第一年和第二年存活率的乘积，为0.618。这些发现凸显了豹幼崽生命早期阶段的关键时期，对于在碎片化栖息地制定有效的保护策略以提高它们的存活率至关重要。
