- Abstract
Intraperitoneal implantation of radio-transmitters is a useful method of monitoring free-ranging aquatic and semi-aquatic mam mals; however, some researchers are concemed about the physiological effects of such implants. Few studies have investigated the long-temi consequences of intraperitoneal implants on survival or reproductive performance. An adult female North American River Otter (Lontra canadensis) surgically equipped with an intraperitoneal radio-transmitter and released in north- westem Pennsylvania in June 1990 as part of a reintroduction project was killed in March 1999. The North American River Otter was estimated to be 10 years old and was pregnant with two fetuses at the time of her death. Our observation suggests that wild North American River Otters surgically equipped with intraperitoneal radio-transmitters can live long after iniplantation of the radio-transmitter and continue to reproduce successfully.
