Pleistocene glaciations had profound impact on the spatial distribution and genetic makeup of species in temperate ecosystems. While the glacial period trapped several species into glacial refugia and caused abrupt decline in large populations, the interglacial period facilitated population growth and range expansion leading to allopatric speciation. Here, we analyzed 40 genomes of four species of ibex and found that Himalayan ibex in the Pamir Mountains evolved independently after splitting from its main range about 0.

The Nicobar treeshrew (Tupaia nicobarica) is an endangered small mammal endemic to the Nicobar Island of the Andaman Sea, India regarded as an alternative experimental animal model in biomedical research. The present study aimed to assemble the first mitochondrial genome of T. nicobarica to elucidate its phylogenetic position with respect to other Scandentians.

We discovered a new Crocidura species of shrew (Soricidae: Eulipotyphla) from Narcondam Island, India by using both morphological and molecular approaches. The new species, Crocidura narcondamica sp. nov.

Pangolins, despite banned through legislative measures, are threatened by heavy illegal poaching for the demand of meat and scales in the making of Traditional East Asian Medicines (TEAM), resulting in severe decline of the population sizes across the distribution range. Species assignment from the confiscated scales is pre-requisite to enforce the appropriate national and international law and legislations in the successful prosecution of the cases in the court of law. In the present study, we characterised the morphological features in voucher specimens of the Indian pangolin (Manis crassicaudata) and Chinese pangolin (Manis pentadactyla) and used the identified keys to establish the species identity from the confiscated scales.

Poaching of South Asian river dolphins is considered one of the main reasons for the rapid decline of their natural populations. To curb the escalated rate of poaching, high numbers of oil and meat seizures are recovered with subsequent convictions by the law enforcement agencies. In this connection, we report a case where suspected animal oil was confiscated by the forest official of West Bengal.

Large mammals that occur in low densities, particularly in the high-altitude areas, are globally threatened due to fragile climatic and ecological envelopes. Among bear species, the Himalayan brown bear (Ursus arctos isabellinus) has a distribution that is restricted to Himalayan highlands with relatively small and fragmented populations. To date, very little scientific information on the Himalayan brown bear, which is vital for the conservation of the species and the management of its habitats, especially in protected areas of the landscape, is available.

Demand for pangolin scales in East Asia has increased dramatically in the past two decades, raising concern to the pangolin survival and bringing them to the brink of local extinction. Enumerating the number of individuals from the seized pangolin scales primarily goes undocumented, mostly due to the unavailability of the appropriate methods. In this study, we developed a Pangolin Indexing System, a multi-locus STR panel of eight dinucleotide microsatellites that showed promising results in individualization and assignment of scales into Chinese and Indian pangolins.
