b) Density estimation of Tiger across study sites:
Using photo captures, tiger density was estimated in SECR framework
using maximum likelihood approach (Borchers & Efford, 2008). The
analysis was carried out in program R (3.5.3) (R Core Team, 2013) using
package ”secr” (3.2.1) (Efford & Efford, 2019). In SECR, we laid a
buffer of 7 km based on spatial scale detection (σ) around our camera
trap matrix. The best-fit model based on the lowest AIC value was then
selected for density (\(\hat{D}\)), capture probability at activity
center (gο), and spatial scale of detection (σ).
