- Journal Article2010Bird use of rice fields in the Indian subcontinentWaterbirds 33 (Special Publication 1): 44-70.
The Indian subcontinent has the world’s highest cropland cover per unit area with rice (Oryza sativa) being the second-most important crop, and is home to nearly 1,300 species of birds. The significance of rice fields as bird habitat in the region is not well understood and the subject is reviewed using a combination of published and secondary information. Rice fields in the subcontinent are used by at least 351 species, although only 2.7% of birds occurring in the subcontinent breed in rice fields. The spread of rice cultivation and its attendant secondary habitats may have contributed to the increase in range and population of 64 common species but is threatening hundreds of other species, many of conservation concern. Most work in the region has focused on birds as pests of rice. Few studies have been conducted on the habits of birds that use rice fields and fewer still have compared how rice fields and similar natural habitats differ. Although rice harvesting has caused nest mortality for breeding birds, there is no comparable information from natural habitats. The guild structure of birds in rice fields is similar to that overall in the region except for a higher representation of carnivores. Rice fields are used primarily by grassland and wetland species. There are large information gaps that require filling to be able to ascertain the utility or impact of rice fields to bird populations and, thus, many research opportunities.

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.

Conservation scientists and policy makers are increasingly aware of the role countryside habitats play in supporting tropical fauna in modern landscapes. We studied the value of different land-uses by examining composition of tropical bird communities and mixed-species bird flocks in human-altered landscapes of Thattekad and the Anamalai Hills, situated in two different altitudes, in the southern Western Ghats. Sixteen line transects distributed across tropical rainforests, shade plantations of coffee and cardamom, timber monocultures of teak, tea plantations, and home-gardens were surveyed for bird flocks, vegetation structure, foliage profile, and canopy attributes. Results indicate that tea plantations were extremely altered habitats, supporting few rainforest species and were devoid of mixed-species bird flocks. Teak monocultures had high species density but were less conducive for rainforest species that require a well developed and structurally more complex habitat. While bird species richness varied little across land-uses, there was significant variation in community composition, with some sensitive bird species absent from all altered habitats. Coffee plantations with surviving rainforest fragments and cardamom plantations with more native shade trees that mimicked a forest habitat supported more rainforest bird species both in communities and flocks. Maintenance of these shade plantations and restoration of forest fragments is recommended, while their conversion into a poor, more open habitat (tea, teak) is strongly discouraged for bird conservation in fragmented landscapes.

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.
