Data from: Variation in harbour porpoise activity in response to seismic survey noise
Animals exposed to anthropogenic disturbance make trade-offs between perceived risk and the cost of leaving disturbed areas. Impact assessments tend to focus on overt behavioural responses leading to displacement, but trade-offs may also impact individual energy budgets through reduced foraging perf...

Animals exposed to anthropogenic disturbance make trade-offs between perceived risk and the cost of leaving disturbed areas.
