Caribou live in herds of thousands which presents dangers for wolves. Elk live in small herds and these are a safer target. [4] A wolf carries its head at the same level as its back, lifting it only when alert. [9] In one study, wolves detected moose using scent ten times, vision six times, and once by following tracks in the snow.
The wolves could benefit from the hyena's superior sense of smell, to locate and dig out tortoises, to crack open large bones, and to tear open discarded food containers like tin cans. [ 30 ] As with other wolf subspecies, Arabian wolves can facilitate a trophic cascade by suppressing smaller carnivores such as golden jackals ( Canis aureus ...
Hyenas do not take to eating wolf flesh readily; four hyenas were reported to take half an hour in eating one. Overall, the two animals typically ignore each other when no food or young is at stake. [61] Wolves will confront a hyena approaching too closely to their dens by taking turns in biting the hyena's hocks until it retreats. [4]
Northwestern wolves are one of the largest subspecies of wolves. In British Columbia, Canada, five adult females averaged 42.5 kg or 93.6 lbs with a range of 85 lbs to 100 lbs (38.6 - 45.4 kg) and ten adult males averaged 112.2 lbs or 51.7 kg with a range of 105 lbs to 135 lbs (47.6 - 61.2 kg), with a weight range for all adults of 38.6 kg to 61.2 kg (85 – 135 lbs).

In Wisconsin, wolves have become a bitter topic, resulting in hours of testimony over the Department of Natural Resources’ proposal to maintain a flexible number of animals in the state.
Grey wolves have a wide, natural distribution across the Holarctic that includes many different habitats, which can vary from the high arctic to dense forests, open steppe and deserts. The genetic differences between different populations of grey wolves is tightly linked to the type of habitat in which they live. [ 9 ]
The gray wolf has been endangered in the United States for many years, and recent poaching and habitat loss have further diminished their numbers. Colorado received 15 wolves from Canada, all of ...
The presence of apex predators improves habitat quality and species viability down the food chain. This reintroduction could be a model for repairing ecosystems.
