Radio-transmitter attachment methods for monitoring the endangered eastern barred bandicoot (Perameles gunnii)

Abstract

Radio-tracking is a key technique for monitoring threatened species during ecological research and reintroduction programs. In the case of the endangered eastern barred bandicoot (Perameles gunnii), it has not been possible to radio-track for extended periods (≥3 months) due to difficulties in reliably and safely attaching radio-transmitters. In this study we compared eight attachment methods. Transmitters weighing 1.2-28g were either mounted with adhesive, attached to a collar or implanted into the peritoneum. Intraperitoneal transmitters were superior in terms of attachment duration, but were considered inferior overall as they could not be fitted in the field and had a very short detectio..
