Behavioral “bycatch” from camera trap surveys yields insights on prey responses to human-mediated predation risk
Human disturbance directly affects animal populations but indirect effects of disturbance on species behaviors are less well understood. Camera traps provide an opportunity to investigate variation in animal behaviors across gradients of disturbance. We used camera trap data to test predictions abou...

Camera traps provide an opportunity to investigate variation in animal behaviors across gradients of disturbance.

We predicted that animals in areas with greater predation risk (more wolf activity, less cover) would travel faster and generate fewer photos per event, while animals in areas with less predation risk would linger (rest, forage), generating more photos per event.
