- Book Chapter2014Experientially Acquired Knowledge of the Self in a Nonhuman PrimatePages 81-99 in Sangeetha Menon, Anindya Sinha and B V Sreekantan (editors) Interdisciplinary Perspectives on Consciousness and the Self, Springer, India
The pressures of developing and maintaining intricate social relationships may have led to the evolution of enhanced cognitive abilities in many social nonhuman species, particularly primates. Knowledge of the dominance ranks and social relationships of other individuals, for example, is important in evaluating one’s position in the prevailing affiliative and dominance networks within a primate society and could be acquired through direct or perceived experience. Allogrooming supplants among female bonnet macaques usually involve the subordinate female of a grooming dyad retreating at the approach of a third female, dominant to both members of the dyad, although, in a few exceptional cases, the dominant member of the dyad could, instead, retreat. Retreat by the dominant individual was observed to be positively correlated to the social attractiveness of her subordinate companion, indicating that individual females successfully evaluate social relationships among other group females. Logistic regression analysis revealed the probability of retreat of the dominant female to be significantly influenced by her own dominance rank and those of the other two interacting females. Individual macaques thus possess egotistical knowledge of their own positions, relative to those of others, in the social hierarchy and appear to, therefore, abstract and mentally represent their own personal attributes as well as those of other members of the group. The experiential acquisition of such cognitive knowledge of the self raises important questions about the possible mechanisms underlying the nature of this mental representation and the general ability to categorise social information in non-verbalizing animal species such as macaques.

- 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.

- Journal Article2014Tiger poaching and trafficking in India: estimating rates of occurrence and detection over four decadesBiological Conservation, doi: 10.1016/j.biocon.2014.08.016
Poaching, prey depletion and habitat destruction have decimated the world’s wild tiger population to fewer than 3200–4000. Despite focused efforts, poaching continues to be the key threat to tiger populations in India, home to more than half of the world’s tigers. A rise in the number of incidences of tiger poaching and trafficking may not essentially represent an increase in the actual occurrence of tiger poaching and trafficking, but can instead be an indication of better enforcement. With ad hoc detection rates, it becomes difficult to estimate the true quantum of poaching and the efficiency of enforcement. We empirically estimate the probability of occurrence of tiger crime and that of detecting it during periods of 3–7 years in the past 40 years in the 605 districts of India. We test the hypotheses that tiger crime is influenced by the presence of tiger trade hubs, proximity to a number of tiger habitats, and that tiger poachers prefer to use rail routes over road highways. The annual probability of detecting tiger crime was estimated to be highest (0.46, 95% CI = 0.38–0.54) in the period between 1993 and 1995. Our results identify 73 districts as current tiger crime hotspots with high (>0.5) probability of occurrence of tiger crime. We propose that the probability of occurrence of tiger crime can be a more reliable estimator of changing poaching pressures and that probability of detecting tiger crime provides a robust estimate of the efficiency in tackling tiger poaching and trafficking.
