- Journal Article2007Foraging ecology and time-activity budget of the Arunachal macaque Macaca munzala – A preliminary studyCurrent Science, 93 (4): 532
The Arunachal macaque Macaca munzala was discovered in 2003 from the high altitudes of western Arunachal Pradesh, and described as a new species in 2005. Vir- tually nothing is yet known of this new macaque spe- cies. In order to generate scientific knowledge on this primate, a field study was conducted to collect infor- mation on its ranging patterns, diet and behaviour. Two multimale multifemale troops were observed for a pe- riod of 112 h in Zemithang valley, Tawang District. The two troops, consisting of 22 and 13 individuals re- spectively, spent on an average, 48% of the observed time in moving and foraging, 36% in sitting and rest- ing, and 16% in social interactions. Foraging alone accounted for 29% of the time-activity budget and was the major activity of the macaques throughout the study. The troops had home ranges of 28 ha and 16 ha respectively, much smaller than those of other ma- caque species studied in similar environments else- where. The macaques ranged largely in the secondary scrub habitat in the study area, where they were ob- served to feed mainly on Elaeagnus parvifolia and Erythrina arborescens. Although fruits of the former species constituted more than 65.8% of the overall diet, this largely frugivorous diet is likely to be seasonal. Our preliminary results suggest the ranging and forag- ing behaviour of the Arunachal macaque to be largely in response to food resource availability. The species also appears to be a typical member of the sinica spe- cies-group of the genus in exhibiting a matrifocal society with tolerant social relationships.

A new species of primate, the Arunachal macaque Macaca munzala, belonging to the sinica species-group of the genus, was described from northeastern India in 2005, and, based on its appearance and distribution, hypothesised to be closely related to M. assamensis and M. thibetana. We subsequently obtained an entire adult male specimen and tissue remains from two other M. munzala individuals. Molecular analyses establish the distinct identity of the species and indicate a time of origin of c. 0.48 mya for it. The species also shows close phylogenetic affinities with the allopatric M. radiata and with the geographically closer M. assamensis and M. thibetana, possibly mediated by male introgression from an ancestral M. assamensis–M. thibetana stock into an ancestral M. munzala stock. Morphometric analyses, on the other hand, reiterate its close similarity only with M. assamensis and M. thibetana, presumably resulting from convergent evolution under similar ecological conditions and along a latitudinal gradient, as predicted by Bergmann’s and Allen’s rules.

The atoll reefs of the Lakshadweep, in the Indian Ocean suffered a catastrophic mortality of hard coral in the wake of the El Niño event of 1998. This study tracked changes to coral and other benthic elements in three atolls in the Lakshadweep from 2000 to 2003. The recovery of coral was highly site-specific, and appeared to be driven by differences in post-settlement survival of coral recruits, that were in turn, influenced by the local hydrodynamics of the atolls. Post bleaching recovery was highest on west-facing reefs, while recovery on east-facing reefs was very limited. However, no ‘phase-shift’ to macroalgal dominated reefs was evident. High herbivore pressures were perhaps the most important control of macroalgae. Five years after the mass mortality, the genera that showed the maximum gains represented a mix of different susceptibilities to bleaching, while some genera that were not particularly susceptible to bleaching showed significant declines. These results suggest that decline or recovery of coral is likely dependent on individual life history strategies, post-recruitment survival, and contingency.

The Ministry of Environment & Forests, Government of India embarked on the process of preparation of its tentative list of natural heritage properties on the world heritage list in 2002 and has identified 7 sub-clusters containing 39 site elements for serial nomination from the Western Ghats in the states of Kerala, Karnataka, Tamil Nadu and Maharashtra. In addition to this, 3 single sites in the states of Arunachal Pradesh, Sikkim and Gujarat have also been identified for inclusion in the tentative list. The tentative list has been prepared through a participative process with active partnership between government, scientific institution (Wildlife Institute of India, Dehradun) and civil society organizations (Ashoka Trust for Research in Ecology and Environment, Bangalore and Nature Conservation Foundation, Mysore)

As large nature reserves occupy only a fraction of the earth’s land surface, conservation biologists are critically examining the role of private lands, habitat fragments, and plantations for conservation. This study in a biodiversity hotspot and endemic bird area, the Western Ghats mountains of India, examined the effects of habitat structure, floristics, and adjacent habitats on bird communities in shade-coffee and cardamom plantations and tropical rainforest fragments. Habitat and birds were sampled in 13 sites: six fragments (three relatively isolated and three with canopy connectivity with adjoining shade-coffee plantations and forests), six plantations differing in canopy tree species composition (five coffee and one cardamom), and one undisturbed primary rainforest control site in the Anamalai hills. Around 3300 detections of 6000 individual birds belonging to 106 species were obtained. The coffee plantations were poorer than rainforest in rainforest bird species, particularly endemic species, but the rustic cardamom plantation with diverse, native rainforest shade trees, had bird species richness and abundance comparable to primary rainforest. Plantations and fragments that adjoined habitats providing greater tree canopy connectivity supported more rainforest and fewer open-forest bird species and individuals than sites that lacked such connectivity. These effects were mediated by strong positive effects of vegetation structure, particularly woody plant variables, cane, and bamboo, on bird community structure. Bird community composition was however positively correlated only to floristic (tree species) composition of sites. The maintenance or restoration of habitat structure and (shade) tree species composition in shade-coffee and cardamom plantations and rainforest fragments can aid in rainforest bird conservation in the regional landscape.

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.
