Behavioral “bycatch” from camera trap surveys yields insights on prey responses to human‐mediated predation risk
Abstract Human disturbance directly affects animal populations and communities, but indirect effects of disturbance on species behaviors are less well understood. For instance, disturbance may alter predator activity and cause knock‐on effects to predator‐sensitive foraging in prey. Camera traps pro...
