Article
Tool use and manufacture by wild nonhuman primates in nonforaging contexts — an important indicator of their technical intelligence — is widespread across taxa, but is sporadic in occurrence. Such behaviors are usually displayed by one or a few individuals within a population and typically occur in four contexts: aggression, communication and sexua...

Group living primates often participate in between-group encounters to defend monopolizable resources. Participation in an encounter is influenced by the density and abundance of resources and the relative fighting ability of groups. We studied between-group encounters in three groups of Nicobar long-tailed macaques (Macaca fascicularis umbrosus) i...

Macaques possess a repertoire of extractive foraging techniques that range from complex manipulation to tool-aided behaviors, to access food items that increase their foraging efficiency substantially. However, the complexity and composition of such techniques vary considerably between species and even between populations. In the present study, we...
Article
Full-text available
Between-group encounters are an obvious outcome of intergroup competition. Between-group encounters in primates range from avoidance to fatally aggressive. The prevailing hypotheses explain such encounters as mate defense strategy by males and resource defense strategy by females. However, the rate and nature of between-group encounters may also be...

Natural disasters pose a threat to isolated populations of species with restricted distributions, especially those inhabiting islands. The Nicobar long tailed macaque.Macaca fascicularis umbrosus, is one such species found in the three southernmost islands (viz. Great Nicobar, Little Nicobar and Katchal) of the Andaman and Nicobar archipelago, Indi...

The Green Plateau Organization has launched an initiative for skill development programme with an interdisciplinary approach –“Basic Wildlife Monitoring Techniques”– to impart scientific knowledge on basic wildlife monitoring techniques using an active learning approach. The programme included field-based training to hone applied technical skills,...

Changes in the habitat can drive the species to adapt to the changing environment that may lead to a risk of infection and the emergence of diseases. The prevalence of gastrointestinal parasites (henceforth endo-parasites) in a species is an indicator of changing habitat conditions, and the study of the same is important when the species is restric...

Anthropocene—the recent human-dominated geological epoch during which humans have intentionally or unintentionally altered the earth’s environment through various anthropogenic activities, ultimately shape the biodiversity of this planet. Anthropogenic alteration of nature has a profound impact on non-human life forms, leading to the sixth mass ext...
Article
In primates, males compete for a mate, which is a non-sharable resource. This makes the conditions less conducive for males to have stable relationships. One such special kind of relationship is a bond where the interactions are reciprocated, equitable and differentiated. Bonds in macaque societies are based on the degree of within-group contest co...

Increased occupation of primate habitats by humans has forced primates into close contact with their settlements and crops. We conducted a survey with the island settlers on Great Nicobar Island to investigate the conflict between farmers and Nicobar long-tailed macaques. The conflict may have increased following the 2004 tsunami due to the co-depe...
Article
Primates maintain social bonds with specific individuals in the group by directing grooming toward them. Social grooming is often targeted toward individuals with whom the most benefits can be exchanged, which are usually the high-ranking individuals. We used the Seyfarth model to investigate whether dominance rank alters the distribution of groomi...

A rank changeover is a sexual strategy by primate males to gain access to reproductive females. We observed one such event in the Nicobar long-tailed macaque (Macaca fascicularis umbrosus) at the Great Nicobar Island, India. In the three and half months of the post-rank changeover period, the home range reduced significantly while there was no chan...
Article
The Indian crested porcupine, Hystrix indica, is a significant ecosystem engineer that builds extensive burrows in the semi-arid regions of north-west India. Many different animals use these burrows as temporary retreats or permanent shelters. Camera-traps were used to record 22 species using porcupine burrows, including 10 mammals, 8 birds, 3 rept...

Relocation is one of the mitigating measures taken by either local people or related officers to reduce the human-bonnet macaque Macaca radiata conflict in India. The review on relocations of primates in India indicates that monkeys are unscreened for diseases or gastrointestinal parasites (henceforth endoparasites) before relocation. We collected...

Situated in the foothills of Aravalli, the state of Haryana is known for its lush agricultural lands, replete with ponds, lakes and canals. The significant number of water bodies form the important feeding, breeding and roosting ground for many resident and migratory birds. The Sultanpur Jheel (28º28' N, 76º55' E) of Gurgaon district is such a wetl...

The Nicobar long-tailed macaque (Macaca fascicularis umbrosus) is confined to the southern and central Nicobar archipelago. We have collected demographic and birth data for five groups of M. f. umbrosus to understand their group structure, demography and breeding seasonality. Group size, individuals in age- sex classes and age-sex ratio did not var...

Social relationships in macaque females depend upon food availability, presence of predator and phylogenetic inertia. Uniform and non-monopolizable food resource leads to lesser aggression among the females giving rise to egalitarian society with low linearity in dominance whereas patchily distributed and monopolizable food gives to despotic society with highly linear dominance. Similarly, absence of predators gives rise to an egalitarian society. Not only ecological factors but even phylogeny plays an important role in shaping female society. According to Thierry’s classification long tailed macaque is supposed to be despotic species. If phylogenetic inertia plays the main role then even the Nicobar subspecies is supposed to be despotic even though it is has been separated. Besides, there is a need to understand individual roles in framing a society type. So our proposed study will investigate the ecological factors and phylogenetic underpinnings of female society utilizing social network analysis (SNA) to understand roles played by each female. This section will also have papers from our project on Nicobar Long-Tailed macaques which may not be directly related to social relationships.
