Key factors determining the ecological niche of the Himalayan marmot, Marmota himalayana Hodgson (1841)

Four key factors determining the ecological niche of the Himalayan marmot, Marmota himalayana Hodgson (1841), in the Central Himalayas (Nepal) have been identified. These are elevation above sea level, temperature, the presence of accumulative formations, and feeding conditions. The Himalayan marmot ecologically differs from all other marmots of the world fauna, and the main difference is that the lower boundary of its range lies very high-3000 m above sea level.
