Indian Grey Wolf and Striped Hyaena sharing from the same bowl: High niche overlap between top predators in a human-dominated landscape
The Semi-arid wildlands of the West Bengal state of India are known habitats of Indian Grey Wolf (Canis lupus pallipes) and Striped Hyaena (Hyaena hyaena) in India. However, increasing anthropogenic pressure in these regions is one major factor behind habitat loss and rising carnivore-human conflict...
