A well-characterised sequence length poly- morphism in the serotonin transporter promoter region (5-HTTLPR) influences individual behavioural traits and cognitive abilities in humans and rhesus macaques. Maca- ques have been classified into four continuous grades on the basis of their behavioural attributes, ranging from highly hierarchical and nepotistic species to the most egalitarian and tolerant ones. A comparative study of several species that spanned these grades revealed only rhesus macaques to be polymorphic at the 5-HTTLPR and concluded that the polymorphism was responsible for their despotic and aggressive behaviour (Wendland et al., Behav Genet 36:163–172, 2006). We studied wild populations of three other species and found that the egalitarian and tolerant bonnet and Arunachal macaques are also polymorphic while liontailed macaques, although belonging to the same group, are monomorphic. We thus reject a role for this particular polymorphism in interspecific behavioural vari- ability and show that polymorphic species enjoy greater ecological success possibly due to their higher infraspecific variability in individual behavioural traits.
- Journal Article2010From Bathymetry to Bioshields: A review of post-tsunami ecological research in India and its implications for policyEnvironmental Management 46:329-338
More than half a decade has passed since the December 26th 2004 tsunami hit the Indian coast leaving a trail of ecological, economic and human destruction in its wake. We reviewed the coastal ecological research carried out in India in the light of the tsunami. In addition, we also briefly reviewed the ecological research in other tsunami affected countries in Asia namely Sri Lanka, Indonesia, Thailand and Maldives in order to provide a broader perspective of ecological research after tsunami. A basic search in ISI Web of Knowledge using keywords ‘‘tsunami’’ and ‘‘India’’ resulted in 127 peer reviewed journal articles, of which 39 articles were pertaining to ecological sciences. In comparison, Sri Lanka, Indonesia, Thailand and Mal- dives had, respectively, eight, four, 21 and two articles pertaining to ecology. In India, bioshields received the major share of scientific interest (14 out of 39) while only one study (each) was dedicated to corals, seagrasses, sea- weeds and meiofauna, pointing to the paucity of research attention dedicated to these critical ecosystems. We noted that very few interdisciplinary studies looked at linkages between pure/applied sciences and the social sciences in India. In addition, there appears to be little correlation between the limited research that was done and its influence on policy in India. This review points to gap areas in eco- logical research in India and highlights the lessons learnt from research in other tsunami-affected countries. It also provides guidance on the links between science and policy that are required for effective coastal zone management.

The report of the Elephant Task Force acknowledges the gravityof human-elephant conflicts,and makes a set of potentially far-reaching and forward-looking suggestions to alleviate them. The spirit of most of them is admirable and positive, but the devil, as always, is in the implementation. Managing conflict is as much about protecting farmers and farmlands from elephants as it is about reducing our footprint on the elephant’s domain. The first of five articles that discuss the Elephant Task Force report.
- Journal Article2010Trawling the shorelinesSeminar. September 2010. Nature without Borders: A symposium on innovative approaches to conserving nature and wildlife
Fishing in India has grown exponentially. It is an industry adapting to its own economic impulses, keeping itself afloat – quite literally – by responding to changes in supply and demand, seeking new markets, repackaging its products and by-products to woo these new markets, reinventing itself constantly in order to survive. The upshot of this industrial inventiveness is that a system of production that should have been designated unsustainable years ago, continues to persist at an increasing ecological cost. And since all of this happens beneath the waves, it largely escapes the noisy debates over the vanishing wilds.
In this paper we present a potted history of trawl fishing along the Indian coastline, and trace its ecological and economic fallout to coastal communities, both human and marine. We discuss the factors currently driving the economics of trawling within the Indian scenario, and explore potential directions towards a more meaningful management of this harvest. Our discussion focuses on fishery off the Coromandel coast, since that is the area we are most familiar with, but it is indicative of much of the rest of the Indian coastline.

Tropical bottom trawling is among the most destructive fishing practices, catch- ing large quantities of bycatch, which are usually discarded. We used question- naire surveys of trawl fishers to look at changes in catches over the last 30 years (1978–2008) along India’s Coromandel Coast. We show that catches and in- come from target species have declined sharply over the last two decades. Meanwhile, costs of fishing have increased substantially and now almost ex- ceed income from target species. Over the same period, bycatch (which was traditionally discarded) has now become increasingly marketable, being sold for local consumption, and as fish meal to supply the region’s rapidly growing poultry industry. Without this income from bycatch, the fishery would scarcely be economically viable. While such a change in the use of bycatch is good news in terms of reducing waste and improving livelihoods, it is also responsible for pushing the Indian bottom trawl fishery beyond the economic extinction of its target species.

The Nilgiri Biosphere Reserve, at the tri-junction of Tamil Nadu, Kerala and Karnataka, constitutes arguably one of the finest conservation landscapes in the global range of the tiger. We surveyed the southern part of this region, as well as the adjoining areas, to assess the status of large mammals both within and outside protected areas. Our field assessments suggest that large mammals are almost exclusively confined to protected areas with the few remaining populations outside under severe threat from habitat degradation and poaching. However, large stretches of contiguous forests still remain. We suggest the extension of the recently notified Mudumalai Tiger Reserve in Tamil Nadu such that connectivity is retained and strengthened with Biligiri Rangaswamy Temple Wildlife Sanctuary of Karnataka to the north-east and with Silent Valley National Park of Kerala to the south. We also provide suggestions on strengthening conservation in this landscape. The involvement of local communities in the establishment of the Siruvani Conservation Reserve in Kerala and Tamil Nadu, and Nilambur Conservation Reserve in Kerala, will bolster the conservation of large mammals in this landscape. With the suggested extension, Mudumalai Tiger Reserve has the potential of becoming arguably the finest habitat for tigers across Asia, given the variations in altitude, topography and climate which produce a diversity of vegetation types and consequently, provide the tiger with an assortment of prey ranging from Nilgiri Tahr in the high altitude montane grasslands to Blackbuck in the low-lying dry deciduous and thorn scrub forests.
