| Abstract: | Long-term data of large felids is important to understand their reproductive biology and behavior for effective conservation planning. We used camera trap data and direct sightings from 2005 to 2013 to estimate the age of the first parturition of Bengal tigers (Panthera tigris) in a semi-arid habitat in India. We monitored 11 females in the Ranthambhore Tiger Reserve (RTR) from when they were 2–6 months old. The mean age at first reproduction (impregnation leading to cubs) was 51.3?±?(SE) 4.5 months. The tiger population in RTR is an important source population and genetic pool in the western most distribution of tiger. Thus, continuous monitoring of tiger populations is important to develop an understanding of reproductive biology. |
