    Genetic assessment of the Non-descript pig breeds across selected regions of Uttarakhand
    (Wildlife Institute of India, Dehradun, 2023) Sahoo, Khushboo; Gupta, S.K.; Gopi, G.V.
    India, which has ancient history of pig rearing, is home to several indigenous pig breeds that reflect the adaptation of Sus scrofa to different environmental and cultural conditions. However, only 13 of these breeds are currently recognized and documented by the National Bureau of Animal Genetic Resources. The present research was undertaken to identify the spatial distribution, socio-economic status, pig husbandry methods of pig rearers, and the impact of Exotic pig breed on the indigenous breed and ecology of the region. As molecular characterization is a valuable tool that provides insights into the evolutionary history and genetic diversity of the current pig breed raise in a region. Hence by incorporating molecular techniques in understanding of the domestic pig breed and their interactions with ecosystems, promote more precise and science-based management that contributes to biodiversity conservation and sustainable husbandry practices. The present study will also aim to evaluate the maternal lineage, genetic diversity and population structure of the domestic pig breeds at the regional scale, using microsatellite markers and mitochondrial DNA sequences. The survey and sampling was done in the planar (Dehradun, Haridwar and Nainital) districts of Uttarakhand, a mountainous state of India that lies in the foothills of Himalayas, where rapid urbanisation and continuous migration make us reconsider the necessity of an organise promotion of the piggery sector due to its multiple ecological implications.

    Study on distribution and relative abundance of large mammals and impact of human disturbance in and arond Mehao Wildlife Sanctuary, Arunachal Pradesh
    (Wildlife Institute of India, Dehradun, 2023) Ahmed, Arif; Gopi, G.V.
    The current study was started to gather baseline data on a few ecological factors (Diversity, distribution, relative abundance, Activity pattern and habitat preference) of selected large animals in Mehao WS. Northeast India. The study period was November 2017 to 2020. The objectives of the study are 1. To estimate the relative abundance and occupancy of selected large mammals in and around Mehao wildlife sanctuary. 2. To develop Habitat suitability model for selected large mammals in and around Mehao WS 3. To analyse the land use/land cover change pattern and to identify the main driving factors.

    Foraging ecology of Great-Slaty Woodpecker in and around Pawalgarh Conservation reserve in Western Himalaya
    (Wildlife Institute of India, Dehradun, 2024) Kaur, Sarabjeet; Gopi, G.V.; Uniyal, V.P.
    The Great Slaty Woodpecker (Mulleripicus pulverulentus, Temminck 1826) is an old-world woodpecker that prefers mature and old-growth dipterocarp forests (including Shorea robusta, Sal) across its known distribution range. The study reveals population demography, the social system and foraging behavior from logged forest and infer the distribution and home range of the Great Slaty Woodpecker, a cooperative breeding bird species, in and around the Pawalgarh Conservation Reserve in the western Himalaya of Uttarakhand state. This study presents the first census conducted for the Great Slaty Woodpecker, providing an ecological baseline for the species population estimation from its known distribution range. I inferred the home range size of each group based on 161 independent sightings of 11 family groups. These sightings represent behaviors such as foraging, nesting, roosting, vocalizations, and territory defense
