Effects of intraperitoneal transmitter implants on yellow-bellied marmots [Effets d'implants d'émetteurs intrapéritonéaux chez les marmottes à ventre jaune].

Résumé

I implanted radio transmitters in 183 yellow-bellied (Marmota flaviventris) transmitters were replaced less or equal 6 times in 73 animals, for 300 surgeries. Surgical procedures were simple, effective, and largely trouble-free. Survival 30 days later was more or equal 98%, and growth rates (21 g/day) were the same for animals with or without implants. Pregnancy rate (0.52 litters/yr) and mean litter size (4.3) of implanted females were similar to pregnancy rate (0.48) and litter size (4.2) of females without implants. Intraperitoneal implants offer an alternative to radio collars for yellow-bellied marmots.
