- Journal Article2014Long-lived benthic predators require structurally stable reefs in the face of repeated climate-change disturbancesCoral Reefs. 33: 289-302
Benthic recovery from climate-related disturbances does not always warrant a commensurate functional recovery for reef-associated fish communities. Here, we examine the distribution of benthic groupers (family Serranidae) in coral reef communities from the Lakshadweep archipelago (Arabian Sea) in response to structural complexity and long-term habitat stability. These coral reefs that have been subject to two major El Nin ̃o Southern Oscillation-related coral bleaching events in the last decades (1998 and 2010). First, we employ a long-term (12-yr) benthic- monitoring dataset to track habitat structural stability at twelve reef sites in the archipelago. Structural stability of reefs was strongly driven by exposure to monsoon storms and depth, which made deeper and more sheltered reefs on the eastern aspect more stable than the more exposed (western) and shallower reefs. We surveyed groupers (species richness, abundance, biomass) in 60 sites across the entire archipelago, representing both exposures and depths. Sites were selected along a gradient of structural complexity from very low to high. Grouper biomass appeared to vary with habitat stability with significant differences between depth and exposure; sheltered deep reefs had a higher grouper biomass than either sheltered shallow or exposed (deep and shallow) reefs. Species richness and abundance showed similar (though not significant) trends. More interestingly, average grouper biomass increased exponentially with structural complexity, but only at the sheltered deep (high stability) sites, despite the availability of recovered structure at exposed deep and shallow sites (lower-stability sites). This trend was especially pronounced for long-lived groupers (life span [10 yrs). These results suggest that long-lived groupers may prefer temporally stable reefs, independent of the local availability of habitat structure. In reefs subject to repeated disturbances, the presence of structurally stable reefs may be critical as refuges for functionally important, long-lived species like groupers.

- Book2014Nature Without BordersOrient Blackswan
Nature Without Borders explores the ways in which conservation of biodiversity can coexist with human actions and interests through a series of different essays. While wildlife conservation in India has traditionally depended on fencing off fragments of areas and habitats and guarding them against human encroachment, such an approach is limited in value, given that formally designated Protected Areas occupy a very small proportion of territory and that nature and natural processes transcend human boundaries and cannot be contained within the borders of nature reserves. Effective conservation, therefore, cannot ever depend on limiting or excluding human activity when habitats and environments themselves have porous boundaries.
Recent research, moreover, shows that effective conservation efforts can occur beyond the borders of Protected Areas and within human settlements. This eclectic collection of essays explores this more inclusive form of conservation through case studies that focus on different species, different environments (whether urban or rural), and different social and political constituencies from local farming or fishing communities to the educated middle class to corporate interests and the state. The essays range from overfishing along the Indian shoreline to the fate of the Gangetic river dolphin and from Sarus Cranes in the rice fields of Uttar Pradesh to the enigmatic snow leopard in the Himalayas. They explore the pastures of the Deccan plateau and the plantations of the Western Ghats as well as the lakes of Bengaluru and urban forests in Delhi. In sum, they offer readers insight into the scope of inclusive conservation that adapts its principles and practices to human activity across a diversity of environments and contexts.
This book will be of interests to students and scholars of ecology and environmental studies, environmental history and sociology. It will also be of interest to nature and conservation specialists and activists as well as policy makers and planners.

Single Small-toothed Palm Civets Arctogalidia trivirgata were seen and photographed on two consecutive nights in March 2014 in Dampa Tiger Reserve, Mizoram, India. They visited a fruiting tree used also by Masked Palm Civet Paguma larvata and Common Palm Civet Paradoxurus hermaphroditus. The present note describes the observation, adding to the few recent records of A. trivirgata from North-east India. The sighting was close to the location of a 1995 sighting of Stripe-backed Weasel Mustela strigidorsa, another species rarely recorded in the region. We suggest further targeted spotlighting and camera-trap surveys for better documentation of the occurrence and distribution of small carnivores in Dampa.

Habitat fragmentation affects species distribution and abundance, and drives extinctions. Es- calated tropical deforestation and fragmentation have confined many species populations to habitat rem- nants. How worthwhile is it to invest scarce resources in conserving habitat remnants within densely settled production landscapes? Are these fragments fated to lose species anyway? If not, do other ecologi- cal, anthropogenic, and species-related factors mitigate the effect of fragmentation and offer conservation opportunities? We evaluated, using generalized linear models in an information-theoretic framework, the effect of local- and landscape-scale factors on the richness, abundance, distribution, and local extinction of 6 primate species in 42 lowland tropical rainforest fragments of the Upper Brahmaputra Valley, northeastern India. On average, the forest fragments lost at least one species in the last 30 years but retained half their original species complement. Species richness declined as proportion of habitat lost increased but was not significantly affected by fragment size and isolation. The occurrence of western hoolock gibbon (Hoolock hoolock) and capped langur (Trachypithecus pileatus) in fragments was inversely related to their isolation and loss of habitat, respectively. Fragment area determined stump-tailed (Macaca arctoides) and northern pig-tailed macaque occurrence (Macaca leonina). Assamese macaque (Macaca assamensis) distribution was affected negatively by illegal tree felling, and rhesus macaque (Macaca mulatta) abundance increased as habitat heterogeneity increased. Primate extinction in a fragment was primarily governed by the extent of divergence in its food tree species richness from that in contiguous forests. We suggest the conservation value of these fragments is high because collectively they retained the entire original species pool and individually retained half of it, even a century after fragmentation. Given the extensive habitat and species loss, however, these fragments urgently require protection and active ecological restoration to sustain this rich primate assemblage.
