Differential vulnerability of key threatened mammals to climate and land cover changes in the Central Himalayas

Ecosphere, Volume 16, Issue 4, April 2025.
Abstract Anthropogenic climate change affects biological diversity by altering their suitable habitat ranges. The Himalayan region is one of the world's most sensitive biodiversity hotspots to global climate change. The Chitwan Annapurna Landscape (CHAL) in the central Himalayas serves as a vital north–south linkage among the protected areas in central

A global assessment of large terrestrial carnivore kill rates

Biological Reviews, Volume 100, Issue 1, Page 327-350, February 2025.
ABSTRACT Through killing and instilling fear in their prey, large terrestrial carnivores shape the structure and function of ecosystems globally. Most large carnivore species have experienced severe range and population declines due to human activities, and many are now threatened with extinction.

Contrasting evidence of phylogenetic trophic niche conservatism in mammals worldwide [PDF]

, 2017
Aim Phylogenetic niche conservatism (PNC), a pattern of closely related species retaining ancestral niche-related traits over evolutionary time, is well documented for abiotic (Grinellian) dimensions of the ecological niche.

Interspecific interactions among major carnivores in Panna Tiger Reserve: A multispecies occupancy approach

Biotropica, Volume 56, Issue 6, November 2024.
This study illustrates that coexistence with the apex predator is feasible through strategic adaptation to fulfill the resource requisition. Abstract Large carnivores play a crucial role in trophic cascades, affecting the population dynamics of both co‐predators and prey within an ecosystem. Understanding the significance of these carnivores in trophic

Melursus ursinus, the sloth bear

, 2008
Bears are large animals, easily recognised by their large head set with small eyes and rounded ears, heavy body, massive, short limbs and a hardly visible tail. Bear sculptures are hard to find. Two examples of realistic sloth bear statues are known from the region of Mathura, Uttar Pradesh, and from Bhaktapur, Nepal.

A most aggressive bear: Safari videos document sloth bear defense against tiger predation

Ecology and Evolution, Volume 14, Issue 7, July 2024.
We collected and examined 43 videos, and photo documentations, of sloth bear–tiger interactions posted on the internet or social media mainly by tourists visiting tiger parks in India. We observed that sloth bears were most likely to stand up and charge if they first became aware of the tiger at close range (<3 m away).

Schrodinger’s scat: a critical review of the currently available tiger (Panthera Tigris) and leopard (Panthera pardus) specific primers in India, and a novel leopard specific primer [PDF]

, 2016
BACKGROUND: Non-invasive sampling has opened avenues for the genetic study of elusive species, which has contributed significantly to their conservation. Where field based identity of non-invasive sample is ambiguous (e.g.
