    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.

    Distribution of breeding Phylloscopus and Seicercus warblers in the Himalayas: Role of ecomorphology and competition.
    (Wildlife Institute of India, Dehradun, 2012) Ghosh, Mousumi; Rawat, G.S.; Price, Trevor
    Present study is carried out for the overarching goal of understanding the ecological and historical determinants of geographic and altitudinal distribution of sixteen breeding Phylloscopus and Seicercus species in the Himalayas. The broad research objectives were as follows: 1. Assess the availability of arthropod resources across the eastern and western Himalaya along the elevational gradients. 2. Identify the climatic correlates of the breeding distribution of Phylloscopidae. 3. Examine the geographic variation in foraging ecology of Phylloscopidae across the Himalayan bioclimatic gradient.
