- Journal Article2006Mammals of the high altitudes of Western Arunachal Pradesh, Eastern Himalaya: an assessment of threats and conservation needs.Oryx 40(1): 1-7.
The high altitudes of Arunachal Pradesh, India, located in the Eastern Himalaya biodiversity hotspot, remain zoologically unexplored and unpro- tected. We report results of recent mammal surveys in the high altitude habitats of western Arunachal Pradesh. A total of 35 mammal species (including 12 carnivores, 10 ungulates and 5 primates) were recorded, of which 13 are categorized as Endangered or Vulnerable on the IUCN Red List. One species of primate, the Arunachal macaque Macaca munzala, is new to science and the Chinese goral Nemorhaedus caudatus is a new addition to the ungulate fauna of the Indian subconti- nent. We documented peoples’ dependence on natural resources for grazing and extraction of timber and medicinal plants. The region’s mammals are threatened by widespread hunting. The snow leopard Uncia uncia and dhole Cuon alpinus are also persecuted in retaliation for livestock depredation. The tiger Panthera tigris, earlier reported from the lower valleys, is now apparently extinct there, and range reductions over the last two decades are reported for bharal Pseudois nayaur and musk deer Moschus sp.. Based on mammal species richness, extent of high altitude habitat, and levels of anthropo- genic disturbance, we identified a potential site for the creation of Arunachal’s first high altitude wildlife reserve (815 km2). Community-based efforts that provide incentives for conservation-friendly practices could work in this area, and conservation awareness programmes are required, not just amongst the local communities and schools but for politicians, bureaucrats and the army.

The recently described Arunachal macaque, Macaca munzala, has to date been reported only from western Arunachal Pradesh, Eastern Himalaya. Our surveys have recorded a total of 35 troops and 569 individuals, probably a conservative estimate, for the macaque population in the Tawang and West Kameng districts of the state. The species appears to be tolerant to anthropo- genic habitat change, but is vulnerable to hunting and retaliatory killing in response to crop damage. Data from one part of the area surveyed, however, indicate that the species can attain remarkably high population densities in the absence of hunting. Macaca munzala will need to be protected in human-modified landscapes, and the issues of crop damage and retaliatory persecution must be addressed urgently.

Changes in tree, liana, and understory plant diversity and community composition in five tropical rain forest fragments varying in area (18–2600 ha) and disturbance levels were studied on the Valparai plateau, Western Ghats. Systematic sampling using small quadrats (totaling 4 ha for trees and lianas, 0.16 ha for understory plants) enumerated 312 species in 103 families: 1968 trees (144 species), 2250 lianas (60 species), and 6123 understory plants (108 species). Tree species density, stem density, and basal area were higher in the three larger (> 100 ha) rain forest fragments but were negatively correlated with disturbance scores rather than area per se. Liana species density, stem density, and basal area were higher in moderately disturbed and lower in heavily disturbed fragments than in the three larger fragments. Understory species density was highest in the highly disturbed 18-ha fragment, due to weedy invasive species occurring with rain forest plants. Nonmetric multidimensional scaling and Mantel tests revealed significant and similar patterns of floristic variation suggesting similar effects of disturbance on community compositional change for the three life-forms. The five fragments encompassed substantial plant diversity in the regional landscape, harbored at least 70 endemic species (3.21% of the endemic flora of the Western Ghats–Sri Lanka biodiversity hotspot), and supported many endemic and threatened animals. The study indicates the significant conservation value of rain forest fragments in the Western Ghats, signals the need to protect them from further disturbances, and provides useful benchmarks for restoration and monitoring efforts.

The reefs of the Lakshadweep suffered a mass mortality of coral in 1998, in the wake of an El Niño event of unprecedented severity. In 2002, we conducted a broadscale benthic survey of six atolls in this group to check if there were geographic trends in recovery patterns across the archipelago. Four years after the mass mortality, live coral cover was relatively low on most atolls, and thin algal turfs dominated the benthos. Clear benthic differences were apparent between eastern and western aspects of reefs, pointing to the importance of local hydrodynamic conditions in determining recovery rates. Where recovery was the most apparent, it was dominated by fast-growing and bleaching-resistant coral genera. Despite the apparent lack of recovery at many sites, the reef system did not show signs of having suffered a ‘phase shift’ to a macroalgal state. High herbivorous fish abundance was likely responsible in controlling macrophyte levels, and may be crucial for further benthic recovery in these reefs.

Macaca, comprising 20 well-characterized species, represents the largest and one of the most ecologically and socially diverse of all the nonhuman primate genera. We report the discovery of a macaque that is new to science from the high altitudes of western Arunachal Pradesh, a biodiversity-rich state in northeastern India. We propose the scientific name Macaca munzala and the vernacular name Arunachal macaque for the species. It shares morphological characteristics independently with the Assamese macaque (Macaca assamensis) and with the Tibetan macaque M. thibetana; like them, it appears to belong to the sinica species-group of the genus. However, the species is distinctive in relative tail length, which is intermediate between those of Tibetan and Western Assamese macaques, the subspecies with which it is sympatric. It is also unique in its altitudinal distribution, occurring largely at altitudes between 2000 and 3500 m. We provide a morphological characterization of the species, report preliminary data on its field biology and discuss possible taxonomic identity in relation to the other closely-related species of Macaca.

The structure and evolution of primate societies are generally shaped by ecological and social forces of natural selection. The habitat and feeding ecology of primate populations, in particular, largely determine the size of the existing social groups and the pattern of interactions between individuals within and across such groups. The bonnet macaque (Macaca radiata), an Old World monkey endemic to peninsular India, usually lives in seasonal tropical deciduous forests and occurs in typically large multimale multifemale associations. This species, however, appears to have evolved, in re- cent years, a fairly high proportion of small, but rea- sonably stable, unimale troops within one particular population in the Bandipur–Mudumalai wildlife sanc- tuaries of southern India. Demographic analyses indi- cate that, as compared to multimale troops, unimale groups are relatively depleted in subadult and juvenile males, exhibit a unique female-biased birth sex ratio and display extensive female dispersal, all of which may have arisen in response to reproductive monopo- lization by the solitary resident male. Several ecological factors, including food provisioning, may have led to the evolution of this social organization, unique for a seasonally breeding cercopithecine primate. Provisioning of primate groups also leads to a significant increase in intra-troop competition among individuals for the newly available resources. Do such individuals, however, exhibit altered behavioural strategies to alleviate social tension? Changing patterns of social interactions between adult males were also analysed for one particular troop of bonnet macaques in the Mudumalai Wildlife Sanctuary under two ecological situations – as they foraged on their natural diet and when they gathered provisioned food from tourists visiting the sanctuary. Although feeding competition increased markedly as these individuals alternated between natural foraging and competing for provisioned food, individual macaques were able to adopt appropriate social strategies under such rapidly changing eco- logical regimes. These studies demonstrate the behavioural and social plasticity of a primate species and the value of demographic studies of multiple groups and populations in different ecological environments.

While the Wildlife Act was always meant to recognise and settle the rights of forest dwellers, in practice, it has been used largely as a blunt instrument to bludgeon them with. It is entirely possible that the Tribal Bill could tomorrow become a similar blunt instrument with which to bludgeon wildlife.
