Radio telemetry has become a valuable tool for studying the spatial and reproductive ecology of snakes. Various methodologies have been used to attach radio transmitters to snakes, including external placement with adhesive tape, forced ingestion, and skin glue application. Still, these methods have limitations and negative effects on snakes, such as transmitter loss or alterations in feeding behavior. This study presents the first case of radio transmitter implantation in the species Bothrops alternatus in
Argentina. Two large venomous snakes B. alternatus specimens, were captured from the wild. A procedure was followed based on previous work with specific adaptations for venomous snakes. The specimens were anesthetized with isoflurane and provided with oxygen throughout the surgery. A 2 cm incision was made in each specimen, the muscle was divided, and access to the celomic cavity was obtained. The previously sterilized radio transmitter was placed in this cavity, and its antenna was tunneled under the skin towards the upper body. Subsequently, the muscle layers and skin were sutured with sterile material. The surgery was successful in both specimens, lasting approximately 30 minutes, with rapid recovery post-anesthesia. The transmitters emitted signals detected at distances of up to 500 meters in the field, allowing tracking of the snakes’ movements over 10 days. However, it was observed that the transmitter battery life was shorter than expected, limiting long-term monitoring. This work represents a significant contribution to the field of snake radio telemetry in Argentina, providing a detailed and successful protocol for radio transmitter implantation in venomous snakes.
