Discussion
The study set out to describe ecological niche spaces of three sympatric species of pika (Ochotona macrotis: OM, Ochotona nubrica:ON, and Ochotona ladacensis: OL), examine niche overlaps and widths in the context of ecological specialization under interspecific competition. In addition, it aimed to understand ecological factors that support the presence of these species at different spatial scales in the Ladakh Trans-Himalayas (3100m - 5200m) to inform conservation policy making.
