Why in news
A study by the Centre for Ecological Sciences at IISc found that wildlife fear responses vary significantly depending on whether human interactions are lethal (hunting/fishing) or non-lethal (tourism/research).
Background
The meta-analysis was published in the journal Ecology Letters. It highlights that lethal human interactions cause increased vigilance and reduced foraging in animals, while non-lethal presence results in weaker, variable behavioral changes.
Facts for Prelims
- BodyCentre for Ecological Sciences is a research body at the Indian Institute of Science (IISc)
- FactLethal human interactions (hunting, fishing) elicit strong fear responses and increased vigilance in wildlife
- FactNon-lethal human presence (tourism, research) results in weaker and more variable behavioral changes
For Mains
Q. Discuss how human-wildlife interaction dynamics, specifically the distinction between lethal and non-lethal activities, influence biodiversity conservation strategies.
Dimensions to cover in your answer
- Behavioral adaptation: Animals adjust foraging and vigilance based on the predictability and intensity of human-induced risk
- Conservation trade-offs: Balancing the ecological impact of non-lethal tourism against the severe disruption caused by extractive activities
