Survival of dispersing versus philopatric juvenile snowshoe hares: do dispersers die?

We used radio-telemetry to monitor the survival of dispersing and philopatric juvenile snowshoe hares (Lepus americanus) in southwestern Yukon Territory, Canada, during a cyclic population increase. Neither 28-day survival nor the proportion of hares surviving to breed differed significantly between juvenile hares that dispersed and those that did not, nor was there a significant relationship between dispersal distance and fate (dead or alive). Our results indicate that the overall survival cost associated with natal dispersal is low for snowshoe hares during the early increase of the hare cycle.
