Why in news
A study in Movement Ecology revealed that king cobras in the Sakaerat Biosphere Reserve utilize irrigation canals as corridors to navigate fragmented agricultural landscapes.
Background
Researchers tracked seven king cobras between March 2014 and July 2018. The study found that while snakes moved less in agricultural areas, they relied on natural vegetation patches and irrigation canals to persist near human settlements.

For Mains
Q. Discuss how anthropogenic landscape fragmentation affects the movement ecology of apex predators and the role of man-made infrastructure in maintaining biodiversity corridors.
Dimensions to cover in your answer
- Habitat fragmentation: Reduced movement in agricultural zones limits genetic flow and foraging range.
- Anthropogenic corridors: Irrigation canals acting as unintended conduits for wildlife movement near human settlements.
