Sleeping distance in wolf pairs in relation to the breeding season

August 1, 1978

Changes in sleeping distances in 11 pairs of wild wolves (Canis lupus) were studied to determine if they correlated with stages of the breeding cycle. Aerial radio-tracking and observation were the techniques used. Members of most pairs slept less than 1 m apart at least sometime during proestrus and the first half of the breeding season, but slept farther apart during the second half and after breeding. These changes might be related to differences in serum estrogen levels.
