Demographic responses of arctic hares Lepus arcticus placed on two predominantly forested islands in Newfoundland
During January‐April 1989. we monitored survival, reproduction, and body condition of 19 radio‐collared arctic hares Lepus areticus introduced to two predominantly (80%) forested islands. Merchant (66 1 ha) and Burke (82 6 ha), in Placentia Bay, Newfoundland By late April, bone‐marrow fat (42 7%) an...
