“…Implanted transmitters were not removed at the end of the study because the stress induced by capture and surgical removal of the transmitters would be excessive. In previous studies, transmitters have been left in place without any detectable complications (Davis et al, 1984;Reid et al 1986). All protocols were approved by the Ontario Ministry of Natural Resources Wildlife Animal Care Committee and the Trent University Animal Care Committee.…”

ABSTRACT:In a study of wolf pup survival, intraperitoneal radio transmitters were surgically implanted in 53 (27 male and 26 female) 3.5-to 8-wk-old Eastern wolf (Canis lycaon) pups at den sites in Algonquin Provincial Park, Ontario, Canada, over two whelping seasons (2004 and 2005). Pups were manually removed from dens and initially injected with butorphanol at a dosage of 0.1 mg/kg for sedation and intra-operative analgesia. Anesthesia was induced and maintained with 3% sevoflurane in oxygen via a face mask. Meloxicam (0.3 mg/kg intramuscularly) was given to provide additional analgesia. All surgeries were completed without complications, and pups were readily accepted back into the packs. No postoperative complications were identified, but two pups from a single litter drowned as a result of being moved by the pack to a flooded den following the surgery. In five pups necropsied following natural deaths, transmitters were found lying free within the peritoneal cavity, and there was no evidence of infection at the surgical site or peritonitis. Inhalation anesthesia provided extremely rapid induction (1 min) and recovery (,3 min) and was completely controllable with no residual anesthetic effects. The equipment for inhalation anesthesia was readily portable in field packs, and it has considerable advantages over injectable drugs for small and very young animals such as wolf pups. The utility of the procedure is demonstrated by the minimal effect it had on subsequent pup survival, the rapid recovery of pups following surgery, and the lack of long-term complications as determined by necropsies of pups following natural deaths.

“…Six of the North American River Otters in their study were pregnant at the time of implantation, and they progressed successfully through parturition, with 2 of the females giving birth again in the following season. No adverse effects of the implants were documented at any stage of the reproductive cycle (Reid et al 1986). …”

“…Several studies have investigated the effects of intraperitoneal radio-transmitters on survival and reproduction in aquatic and semi-aquatic mammals (Reid et al 1986;Horning et al 2008). Ralls et al (1989) found no complications associated with intraperitoneal implantation of radio-transmitters in adult Sea Otters (Enhydra lutris) and documented normal reproductive performance in females.…”

“…Several different types of radio-transmitters may be used, depending on factors such as cost, invasiveness, and species morphology and behavior. For aquatic and semi-aquatic mammals, intraperitoneal radio-transmitters are considered particularly practical biotelemetry devices (Smith and Whitney 1977;Melquist and Hornocker 1979;Reid et al 1986;Horning et al 2008) because, unlike radio-collars and harnesses, they are appropriate for the lifestyle and body shape of various species (Garshelis and Siniff 1983;Reid et al 1986;Rado and Terkel 1989;Van Vuren 1989). However, several complications can potentially result from surgery and implantation of intraperitoneal radio-transmitters, including infection, incision dehiscence, and blockage of internal organs.…”

“…After observing low morbidity and zero mortality, Horning et al (2008) concluded that intraperitoneal radio-transmitters are viable radio-tracking devices. Reid et al (1986) assessed the reproductive performance of 7 adult female North American River Otters equipped with intraperitoneal radio-transmitters. Six of the North American River Otters in their study were pregnant at the time of implantation, and they progressed successfully through parturition, with 2 of the females giving birth again in the following season.…”

Long-term Survival and Reproduction in a North American River Otter (<em>Lontra canadensis</em>) with an Intraperitoneal Radio-Transmitter

Intraperitoneal implantation of radio-transmitters is a useful method of monitoring free-ranging aquatic and semi-aquatic mammals; however, some researchers are concerned about the physiological effects of such implants. Few studies have investigated the long-term 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 northwestern 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 implantation of the radio-transmitter and continue to reproduce successfully.
