چکیده انگلیسی

Livestock in high altitudes of Nepal and elsewhere, frequently and freely, use potential habitat of native wildlife for foraging. Such intrusion of ecologically similar domestic species is supposed to negatively impact the resident wildlife via 'perceived' and/or 'real' competitive interactions. Hence, assessment of dietary composition and overlap between herbivores is crucial to gain insight into the potential impacts via resource exploitation by foraging livestock. Also, evaluation of dietary composition of resident wildlife across seasons is important to decipher their seasonal resource needs. Within this context, microhistological technique, that makes use of fecal pellet for identification of plant species through comparison with reference slides of plant materials in the area, was used to assess dietary composition, breadth, and overlap between seasonally sympatric Himalayan musk deer and livestock in Nepal Himalaya. Musk deer and livestock were found to have significantly different dietary consumption and that partition was contributed by different species; meaning different plant species were associated to the diets of these two groups. Of notable, however, was a considerable 'number' of species (i.e., species richness) shared in diets by musk deer and livestock raising a concern of unchecked number of livestock with a potential to exploit and reduce the availability of shared plant species with musk deer. Also, seasonal dietary composition of musk deer significantly varied, with increased dietary breadth in winter, suggesting a potential for intraspecific competition for forage in winter because of limited availability of resources mediated by retarded growth and harsh conditions.
