The alpine musk deer, Moschus chrysogaster, a small member of family Moschidae, is a primitive deer threatened due to poaching and habitat loss, and therefore classified as Endangered by IUCN and also listed in Appendix I of CITES. Although the species is legally protected in India under Wildlife Protection Act 1972, conservation of the species requires better understanding of its distribution and resource-use pattern; therefore, a study on its feeding and habitat ecology was conducted from February 2011 to February 2014, at Kedarnath Wildlife Sanctuary. The Sanctuary is one of the known remaining habitats for musk deer in India. Four locations, namely, Shokhark I, Shokhark II, Tungnath and Chandrashila, were intensively monitored and further categorised on the basis of habitats and altitudinal gradient. The habitat overlap between musk deer and all other ungulate species of the area was calculated through Pianka’s overlap index. The results indicated a large overlap between musk deer and Himalayan tahr. Species dietary spectra were studied using microhistological techniques for faecal pellet-group analysis coupled with Bonferroni approach. The dicotyledon to monocotyledon ratios were found to be 73.62–26.38% and 52.016– 47.984% in the pre- and post-monsoon seasons, respectively. The study showed that the musk deer is predominantly a browser. The most preferred plant species of the animals were found to be Gaultheria trichophylla, Ophiopogon intermedius., Cyperus sp. and Sibbaldia cuneata. During the field survey, opportunistic sightings of the species were also recorded. The species was found to be restricted to areas where the density of preferred vegetation was high. Therefore, it is recommended to provide strict protection to the areas such as Shokhark.

AbstractIncreasing advancement in development activities in the Indian Himalayan region in tandem with changing climate is influencing the ecological patterns of rivers. Thus, the present study investigates the effect of various degrees of anthropogenic stresses and possible implication of thermal dynamics of river water on the macroinvertebrate community in the Mandakini River, which flows in the vicinity of Kedarnath Wildlife Sanctuary of Chamoli district, Uttarakhand. The main objective was to study the community structure of macroinvertebrates in the Mandakini River and to calculate the effect of anthropogenic stresses on the macroinvertebrate community, particularly on Ephemeroptera, Plecoptera, and Trichoptera. The study was carried out in 10 spatially located sampling stations, and the frequency of sampling was divided into pre- and post-monsoon season (May and November 2017). Based on the degree of anthropogenic stresses, sampling locations were divided into least (Sonprayag), medium (Ukhimath), and high disturbed (Rudraprayag) sites. A total of 3257 individuals belonging to 7 orders and 21 families were found in both the sampling season. Diptera and Trichoptera were dominant orders in both the seasons, whereas Baetidae (Ephemeroptera), Hydropsychidae, Leptoceridae (Trichoptera) and Chironomidae (Diptera) were dominant families. Shannon diversity index varies from 2.048 to 2.25 in the least disturbed site (Sonprayag), 0.186–2.446 in medium disturbance (Ukhimath), and 1.362–2.271 in the highly disturbed site (Rudraprayag) in both the sampling season. Quantification of the EPT index shows a negative trend with an increase in anthropogenic stress, and it was least in Rudraprayag as compared to the other two sites. Result of one-way ANOVA shows a significant difference in diversity between pre- and post-monsoon season (p < 0.05). Analyzing the research gaps, it is recommended to have long-term ecological monitoring of high altitude and glacier-fed rivers and streams to obtain robust information regarding the dynamics of the riverine ecosystem in Garhwal Himalayas.
