Radiotracking of dispersing yellow-bellied marmots [Radio-télémétrie des marmottes à ventre jaune dispersantes].

Résumé

Movement of yearling yellow bellied marmots was studied by radio tracking. The equipment developed for this study is described and consists of a surgically implanted transmitter, two types of direction finding antennas and an inexpensive receiver. The results suggest that a river forms a barrier to movements, dispersing animals use burrows of greater separation than resident animals, and dispersion results in a net movement of more than a kilometer from the original colony.
