To trace dung beetles in the sphere, past detection approaches were modified employing a commercially accessible metal detector and metal tags to supply sufficient detection depth with no influencing their survivorship and behaviors. With an increase in acceptance of metal detectors for recreational reasons, these units are becoming a lot more acce
