Seasonal Activity Budgets and Movements of a Reintroduced Alaskan Muskox Herd

Daily activity budgets and group movement rates were recorded on a seasonal basis during 1978-80 for a reintroduced muskox (Ovibos moschatus) herd in arctic Alaska. Muskoxen spent more time lying than in any other activity. Resting periods in early and late winter and during calving were longer (P < 0.05) than during other seasons. Seasonal movements of the herd were limited. The lowest movement rates (x̄ = 0.66 km/day) were during calving and the highest (x̄ = 9.9 km/day) during periods of severe insect harassment. The localized movements of this herd should be considered when trying to minimize the potential impacts of oil exploratory and developmental activities within the Arctic National Wildlife Refuge.
