Footedness in foraging muskoxen Ovibos moschatus

Języki publikacji
We investigated the propensity for wild muskoxen Ovibos moschatus (Zimmerman, 1780) to exhibit right or left bias in foreleg use while foraging during winter. We found little evidence of such latéralisation, either on the individual or population level. Only 3 of 40 animals exhibited significant right- or left-footedness, and the distribution across the population for use of either limb was near 50%. Time-series analysis revealed that latéralisation of paw use was sequentially dependent. Muskoxen tended to use the same paw for one ensuring bout, but were also inclined to switch sides over durations of 4 bouts. The lack of lateral bias, at least for this behaviour, contrasts with the general, emerging pattern for the Mammalia.
