Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds
The Journal of Wildlife Management, EarlyView.Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...
