Why in news
A study by the Centre for Ecological Sciences (IISc) revealed that wildlife responses to human presence vary based on the lethality and predictability of the interaction.
Background
The meta-analysis covered three decades of research on animal behavior. It found that prey species may perceive areas near roads as refuges due to reduced vigilance, while lethal humans like hunters and fishers trigger consistent fear responses.

For Mains
Q. Discuss how anthropogenic landscape modifications and varying intensities of human presence influence wildlife behavioral ecology and conservation strategies.
Dimensions to cover in your answer
- Behavioral adaptation: Animals adjust caution levels based on the predictability of human-induced threats
- Habitat modification: Roadside environments creating 'perceived refuges' altering natural predator-prey dynamics
- Conservation trade-offs: Balancing infrastructure development with the preservation of natural wildlife vigilance patterns
Keywords: Anthropogenic impact · Behavioral ecology · Wildlife conservation · Meta-analysis · Habitat fragmentation
