How absolute biomass intake can alter nutrient profile interpretation in free‐ranging species: the case of protein intake in brown bears

Wildlife Biology, Volume 2025, Issue 6, November 2025.
If an animal eats a large amount of a diet of a low content of a macronutrient, it can still ingest a considerable amount of that macronutrient. Various animals have been shown to balance nutrient content with intake in this way. We use the brown bear Ursus arctos as a model species, given their recent classification as ‘low protein omnivores', to show

The division of food space among mammalian species on biomes

Ecography, Volume 2025, Issue 10, October 2025.
Understanding how species' ecological partitioning functions across biomes is fundamental to macroecology and conservation biology. Here, we examine the global distribution of dietary strategies in terrestrial mammals, focusing on how biome specialization modulates trophic diversity and structure at a broad geographical scale.

Spatial and temporal patterns of mammalian roadkill across subtropical protected areas in Nepal

Ecosphere, Volume 16, Issue 8, August 2025.
Abstract Wildlife–vehicle collisions are a major source of anthropogenic wildlife mortality, making it essential to understand their spatial and temporal patterns for effective mitigation. In this study, we conducted a multisite, multiyear analysis of wildlife roadkill incidents recorded across six subtropical protected areas in Nepal over a five‐year ...

Tropical dry woodland loss in India since 1880 and its relation to current megafauna distributions

Ecological Applications, Volume 35, Issue 5, July 2025.
Abstract Tropical dry woodlands provide ecosystem services to hundreds of millions of people and support high biodiversity. Despite their importance, many dry woodlands are under high and rising human pressure, including in India, where they provide essential habitat for iconic megafauna.

Habitat and Anthropogenic Determinants of Chinese Pangolin (Manis pentadactyla) Burrow Occupancy in Udayapur, Eastern Nepal: Implications for Site‐Specific Conservation

Ecology and Evolution, Volume 15, Issue 6, June 2025.
ABSTRACT Chinese pangolins are found from lowlands to mid‐hills in Nepal and are increasingly vulnerable to extinction due to extensive illegal trade and habitat fragmentation, particularly outside the protected areas network. The information about their ecological preferences in human‐dominated landscapes beyond protected areas is essential for ...

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.

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

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

Ecology and Evolution
Sloth bears are non‐carnivorous yet they attack more people than any other bear. They often stand up and charge explosively if a person mistakenly gets too close. Here, we argue that their aggression toward humans is an extension of their behavior toward
