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.

- Journal Article2010Implications of conserving an ecosystem modifier: Increasing green turtle (Chelonia mydas) densities substantially alters seagrass meadowsBiological Conservation 143: 2730-2738
Ecosystem modifiers have the ability to significantly alter the ecosystem they inhabit sometimes with serious consequences for their own populations. We evaluated the ability of green turtles (Chelonia mydas) to modify seagrass ecosystems by their foraging activity. This study was conducted in a seagrass-dominated lagoon in the Lakshadweep Islands, Indian Ocean, where a stable high-density congregation of green turtles is present. We determined a gradient of turtle density in the lagoon and measured the intensity of turtle herbivory across the gradient. We then measured the impact of increasing grazing on seagrass structural parameters, growth and flowering along this gradient. Our results indicate that turtles substantially change seagrass meadow structure (canopy height, shoot length, width and density), reduce flowering and can potentially even cause changes in the species composition of the meadow. We discuss the implications of these results for seagrass ecosystem function, green turtle movement and human attitudes. When conserving ecosystem modifiers like the green turtle, any management strategy needs to include a detailed knowledge of the roles these species play in the ecosystems they inhabit.

Understanding behavior of elephants in human-dominated landscapes can facilitate creation of management tools for conflict resolution and help foster human-elephant coexistence. We studied behavior of Asian elephants (Elephas maximus) in the Valparai plateau, a 220 km² landscape matrix of rainforest fragments, tea, coffee, and Eucalyptus plantations in the Anamalai Hills of the Western Ghats of India. We studied the nearest neighbor distance among elephants within the herd and their feeding behavior in habitat mosaics. We also recorded reactions of elephants to human proximity and number of people in the vicinity. We employed scan sampling for data collection. Feeding by elephants was lowest in open canopy habitat of tea, and it gradually increased in canopy covered plantations of coffee and Eucalyptus and in densely covered natural vegetation. Vigilance behavior of elephants was lowest in forest fragments and riverine vegetation as they could avoid encountering humans. This behavior peaked in tea plantations due to intense human activity there. Elephants maintained closer inter-individual distances in tea and this distance gradually increased in canopy habitats of coffee, Eucalyptus and natural vegetation. More humans in the vicinity and closer proximity to elephants reduced feeding and increased agitation in elephants, while proximity to settlements did not have any influence. We, therefore, suggest that protection and non-conversion of canopy habitats, restoration of rivers with native species, and maintaining distance from elephants would foster normal activities of elephants and help promote human-elephant coexistence in such landscapes.
