Sometimes there is debate whether the muskox or the Arctic hare is the primary prey for the hare-wolf-muskox predator-prey system. Studies provide evidence that the muskoxen are indeed their primary prey because wolf presence and reproduction seems to be higher when muskox is more available than higher hare availability. [23]
The wolf must give chase and gain on its fleeing prey, slow it down by biting through thick hair and hide, and then disable it enough to begin feeding. [4] After chasing and then confronting a large prey animal, the wolf makes use of its 6 cm (2 + 1 ⁄ 2 in) fangs and its powerful masseter muscles to deliver a bite force of 28 kg/cm 2 (400 lbf/in 2), which is capable of breaking open the ...
The wolf (Canis lupus; [b] pl.: wolves), also known as the grey wolf or gray wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo , though grey wolves, as popularly understood, only comprise naturally-occurring wild subspecies.
However, in 1997, there was a decline in the wolf populations and their prey, muskoxen (Ovibos moschatus) and Arctic hares (Lepus arcticus) across arctic Canada. This was due to harmful weather conditions during the summers for four years. The recovery of the wolf populations came after when summer weather conditions returned to normal. [16]
Wolf howls can under certain conditions be heard over areas of up to 130 km 2 (50 sq mi). [15] Wolf howls are generally indistinguishable from those of large dogs. [16] Male wolves give voice through an octave, passing to a deep bass with a stress on "O", while females produce a modulated nasal baritone with stress on "U".
