PDF, 3.64 MB
Many bat species occur in Indian coffee plantations and despite sporadic reports of damage to commercial coffee crops, the literature shows little evidence for these claims. Measures that have been proposed to ‘control’ fruit bats are likely to be ineffective and even counter-productive. Instead, insect-eating bats should be encouraged by planters as they help control herbivorous and disease-carrying insects, while fruit bats pollinate flowers and disperse seeds of many useful plants and shade tree species. More research is needed to quantify any crop damage caused by bats and to look for sustainable solutions where necessary.

A variety of mechanisms for socially facilitated learning allow animals to acquire information from the behaviour of others, and through their own modified behaviour such information can subsequently be transmitted between individuals within and across generations. Variation in such socially acquired and transmitted behaviours is unlikely to be under direct genetic control since individuals who are closely related genetically can have and pass on very different behaviours; this is also true for cultural traditions that such behaviours may have generated. Behavioural information transfer of this nature thus represents another form of inheritance that operates in many nonhuman species, including primates, in tandem with the more basic genetic system. Most behavioural traditions usually precede genetic adaptations but exert persistent directional selection for genetic variations congruent with the new patterns of behaviour since such traditions lead to the transmission of the same selective regime. Selection for the ability to learn a particular behaviour pattern more efficiently and rapidly may also lead to it becoming dependent on fewer learning trials or none at all – ultimately culminating in a partial or complete incorporation of the trait into the basic genetic inheritance system. This paper reviews principles of culture and its biological foundations, and examines the rôles that behavioural inheritance and socially transmitted cultural traditions play in the structure and dynamics of primate societies, with particular reference to data from long-term field studies on Japanese macaques and from bonnet macaques, a species endemic to peninsular India. Three principal consequences are considered: the appearance of individual behavioural traits leading to the establishment of social traditions, the rôle of stable behavioural traditions in facilitating cultural selection, and the influence of particular behavioural and life-history traits on gene-culture coevolution in nonhuman primates.

Illicit trade in wildlife products is rapidly decimating many species across the globe. Such trade is often underestimated for wide-ranging species until it is too late for the survival of their remaining populations. Policing this trade could be vastly improved if one could reliably determine geographic origins of illegal wildlife products and identify areas where greater enforcement is needed. Using DNA-based assignment tests (i.e., samples are assigned to geographic locations), we addressed these factors for leopards (Panthera pardus) on the Indian subcontinent. We created geography-specific allele frequencies from a genetic reference database of 173 leopards across India to infer geographic origins of DNA samples from 40 seized leopard skins. Sensitivity analyses of samples of known geographic origins and assignments of seized skins demonstrated robust assignments for Indian leopards. We found that confiscated pelts seized in small numbers were not necessarily from local leopards. The geographic footprint of large seizures appeared to be bigger than the cumulative footprint of several smaller seizures, indicating widespread leopard poaching across the subcontinent. Our seized samples had male-biased sex ratios, especially the large seizures. From multiple seized sample assignments, we identified central India as a poaching hotspot for leopards. The techniques we applied can be used to identify origins of seized illegal wildlife products and trade routes at the subcontinent scale and beyond.
