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.

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 global biodiversity hotspot and endemic bird area, the Western Ghats mountain range of India, examined the effects of connectivity of rainforest fragments with shade-coffee plantations and the influence of habitat structure and floristics on tropical rainforest bird communities. Systematic sampling for habitat and birds was carried out in 13 sites, including six fragments (three relatively isolated and three with canopy continuity with adjoining shade-coffee plantations and forests), six plantations differing in canopy tree species composition (five coffee and one cardamom), and one control site containing a large relatively undisturbed primary rainforest in the Valparai plateau of the Anamalai hills. Around 3300 detections of about 6000 individual birds belonging to 106 species were obtained. The plantations were depauperate in relation to rainforest in rainforest bird species, particularly endemic species, but one site (cardamom plantation) with an entirely native canopy of tall rainforest trees, had species richness and bird abundance values comparable to that of primary rainforest. Plantation and fragment sites that were less isolated (more canopy continuity in surrounding landscape) tended to support greater number of rainforest and lesser number of open-forest bird species and individuals than more isolated sites. Rainforest bird richness and abundance were positively related to the vegetation component representing densities of woody plants, canes, lianas, and bamboos. Bird community composition was however related only to floristic (tree species) composition of sites. The results indicate that the maintenance or restoration of such attributes in plantations and fragments can aid in bird conservation in the region. The potential of rainforest fragments and shade-coffee and cardamom plantations for bird conservation outside wildlife protected areas is emphasised.

The high altitude wildlife of Arunachal Pradesh, located in the Eastern Himalaya biodiversity hotspot, has remained unexplored and unprotected. Between August and October, 2003, we undertook a biological expedition in the high altitudes (> 3000 m) of Tawang and West Kameng Districts of Western Arunachal Pradesh, with the objective of inventorying wildlife and identifying areas for the establishment of wildlife reserves. The expedition documented the occurrence of a rich mammalian species assemblage (34 species), 12 of which are of global conservation importance. Our discovery of the Chinese goral Nemorhaedus caudatus represents a new addition to the list of large mammals of the Indian sub-continent. We also recorded a primate belonging to the sinica group of the genus Macaca, which is potentially a species new to science. We recorded 150 bird species, identified 140 plant species, and prepared a preliminary description of the high altitude vegetation. We also documented peoples’ dependence on natural resources (grazing, collection of timber and medicinal plants), and the threats to the region’s wildlife, including widespread hunting, and persecution of the snow leopard Uncia uncia and dhole Cuon alpinus in retaliation against livestock depredation. Preliminary vegetation maps were prepared using field data in conjunction with satellite imageries. Based on information about the wildlife assemblages, extent of high altitude habitat, and levels of anthropogenic disturbance, we identify and propose an important site (815 km²) for the creation of a wildlife reserve. Future conservation efforts need to focus on establishing the state’s first high altitude wildlife reserve, and garnering the support of indigenous people for wildlife conservation through community-based programs.

1. Resource competition is an important process governing the impact of livestock on native wild mammalian herbivores, an issue acknowledged to be of global conservation con- cern. Resource competition occurs between species when their resources (habitat and diet) overlap and are limiting. Yet the evidence that livestock compete with wild herbivores has remained weak because resource limitation is often difficult to demonstrate in the field.
2. This 2-year field study at Bandipur National Park, India, examined livestock-mediated resource limitation among five wild herbivore species: wild pig Sus scrofa, chital Axis axis, sambar Cervus unicolor, gaur Bos gaurus and Asian elephant Elephas maximus, by comparing their distribution and densities in adjoining livestock-grazed and livestock- free areas before, and after, a 49% decline in livestock density.
3. During 2001, mean densities of wild grazers, gaur (0·11 ha−1), chital (1·51 ha−1) and elephant (0·61 ha−1), were, respectively, 132, 11 and six times higher in the livestock-free area than in the adjacent livestock-grazed area. Densities of gaur, chital and elephant showed a sharp declining relationship with increasing livestock density, whereas no clear pattern was discernible with wild pig, a non-ruminant generalist, and the sambar, a forest browser. Preferred plant biomass also fell sharply with increasing livestock density.
4. Following the decline in livestock density in the livestock-grazed area in 2002, the densities of gaur, chital and elephant increased by a factor of 57, five and two in the same area, respectively, whereas no changes were seen in the densities of wild pig and sambar or in the preferred plant biomass. Except for a decline in elephant density, the livestock-free area did not show changes in wild herbivore densities.
5. Given the considerable overlap in habitat and dietary preference/requirements between livestock and wild herbivores in the study area, it is suggested that the recovery of gaur, chital and elephant densities following the livestock decline represents their release from livestock-mediated resource limitation.
6. These results indicate that resource competition may be intense between wild herbivores and grazing livestock, and if left unchecked could trigger declines of wild herbivores, particularly grazing ruminants and bulk feeders. These results also suggest that, where possible, interventions to reduce livestock grazing may rapidly benefit wild herbivores.
