Many primate species show various behavioural and ecological adaptations to provisioning, one of which is the unusual occurrence of twins. Here, we report observations on two pairs of twins in the Puthuthottam population of lion-tailed macaques Macaca silenus in the Anamalai Hills of the Western Ghats and show that some lion-tailed macaque twins can survive under free-ranging conditions if they receive adequate care from their biological mother or another female.

The predictions on the disaster scenarios in the Himalayan states have come true. We are now witnessing the consequences of human interventions that have contributed to the intensity of disasters, impacting the lives and livelihoods of the people.

This study aimed to monitor long-term land use dynamics for understanding the natural forest integrity and intactness of the Rajiv Gandhi (Nagarhole) Tiger Reserve (RTR) pre- and post-declarations as TR. We employed multi-source data from Survey of India Toposheets (1:50 k), Landsat-7, and Sentinel-2A along with Global Ecosystem Dynamics Investigation (GEDI) vegetation canopy height (10 m) data, a high-spatial resolution CORONA (1970) images and temporal Google Earth Pro images for mapping and validation.

China is undertaking its most ambitious and far-reaching reforms and modernisation of the armed forces under Xi Jinping. The reforms are likely to fundamentally change the way PLA operates. If successful, they would reduce the power and influence of the PLA ground forces that so far has dominated the military, promote joint operations, and bring about significant capability build up in the maritime, air, space, and cyber domains.

Nonhuman primates – mostly apes – are known to combine gestural units in non-random ways, but they do not make novel meaning with these combinations. In this paper, we investigated, for the first time, the structure and functions of gesture sequences in the naturally occurring communication of wild bonnet macaques, using analyses akin to ape gesture studies. We discuss our findings in the light of a possibility that primate gesture sequences, coordinating the flow of social interactions, may be evolutionary precursors to pragmatic gestures in human language.
