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.

- 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.

- Journal Article2014Photographic records of the Ratel Mellivora capensis from the southern Indian state of KarnatakaSmall Carnivore Conservation, 50, 42-44.
Understanding about the occurrence and distribution of the Ratel Mellivora capensis from the Indian subcontinent is hindered by the animal’s elusive nature. The first photographic evidence of Ratel for the southern Indian state of Karnataka comprises 41 camera-trap records from Cauvery Wildlife Sanctuary. During January–March 2014, Ratels were detected in the sanctuary’s different forest types broadly in proportion to camera-trapping effort therein. A wider occupancy survey, using a range of methods including camera-trapping, would help obtain a better understanding of the distribution of this cryptic species in Karnataka and neighbouring regions.
- Journal Article2014Spatio-temporal variation in forest cover and biomass across sacred groves in a human-modified landscape of India's Western GhatsBiological Conservation 178: 193-199.
Although the potential for community-conserved areas (CCAs) to extend conservation beyond formal protected areas is widely acknowledged, the scarcity of conservation assessments and monitoring hinders the rigorous evaluation of their effectiveness in many regions. In India, which hosts a high density and diversity of CCAs, the need for more assessments of the ecological and socio- economic properties of these systems to guide conservation planning and policy has been emphasized in recent years. We inventoried the extant sacred grove network against official records of 407 groves across 70 villages in the Kodagu District of India's Western Ghats, and interviewed local communities about their management and conservation. We also evaluated recent trends in aboveground biomass of sacred groves using time-series satellite data from six time-points during the 2000-2010 period, and made comparisons to corresponding trends in nearby State-managed protected forests. Although most of the larger (> 2ha) groves officially listed were forested at present, over two-thirds of the smaller groves listed were either not forested or could not be located. Local communities attributed these declines to encroachment and illicit logging. Time-series satellite data revealed aboveground biomass declines of ~0.5% annually across the sacred grove network over the 2000-2010 period. In contrast, biomass increased during this period at the interiors and edges of State-managed forests in the landscape. Our results highlight that the conservation status of even well-protected CCAs can vary considerably over time, especially given the dynamism in socio-economic, cultural and ecological factors that govern their status. We argue that understanding and addressing this dynamism is crucial to the conservation of CCAs.
