The population of the globally endangered hog deer (Axis porcinus) has declined severely across its geographic range. Intensive monitoring of its demographic and genetic status is necessary. Northeast India is a stronghold of the species; however, in recent years the population has been getting fragmented, and it is vulnerable to extinction. We examined the demographic and genetic structure of a small hog deer population in the floating meadows of Keibul Lamjao National Park (KLNP), located on the western fringe of the Indo-Burma biodiversity hotspot for conservation planning. We used a double-observer distance sampling method to derive the hog deer abundance and population structure. We also derived the genetic diversity of the population through microsatellite screening and bottleneck detection. Our study revealed that the abundance of the deer in the park was 1.82–4.32 individuals/km2. The adult male to female ratio and fawn to doe ratio were 36.2 ± 1.9 males/100 females and 16.5 ± 0.4 fawns/100 females, respectively. The mean number of alleles at 23 loci was 2.70 ± 0.18, the observed heterozygosity (HO) ranged from 0.26 to 0.63 (mean 0.42 ± 0.02), the expected heterozygosity (HE) ranged from 0.23 to 0.73 (χ = 0.51 ± 0.03), ...Continue Reading
