Geographic Range
Lepus othus is found in northern and western Alaska. Some descriptions also place them at the extreme eastern tip of Siberia.
Habitat
Lepus othus tend to live on rocky slopes or upland tundra. They dislike low places. They may also be found in brushy areas that are good for camouflage.
Terrestrial Biomes:
tundra
.
Physical Description
(8.58 to 15.84 lbs; avg. 10.56 lbs)
Alaskan hares are the largest hare species in North America, measuring in length from 0.5 to 0.7 m with a tail length of about 8 cm, and very large hind feet (almost 20 cm long) which aid in movement over snow. There is no sexual dimorphism in size. Alaskan hares have robust skulls, strongly recurved upper incisors, and stout claws for digging in the snow. Unlike most hares, they have fairly short ears to conserve heat in the arctic environment. Lepus othus has a gray-brown topcoat with a white undercoat in the summer, but sheds and grows an entirely white coat in the winter, except for the black fur at the tip of the ears which is present year-round.
Some key physical features:
endothermic
; homoiothermic; bilateral symmetry
.
Sexual dimorphism:
sexes alike.
Reproduction
Lepus othus, in contrast to many other hares, has only one litter per year. This litter tends to be larger on average than other hare species. Litters consist of 4 to 8 (averaging 5) young called leverets. The mating season lasts from April to May and young are born in the summer months, from June to July. They have a somewhat darker pelage than adults. Like all hares, they are born with a full coat of fur and their eyes open. Leverets are fairly active soon after birth. This is useful because they do not live in burrows, but are born in open nest sites above ground.
Key reproductive features:
gonochoric/gonochoristic/dioecious (sexes separate); sexual
.
Behavior
Alaskan hares are mosly active at dusk and dawn, when they forage for food. They tend to be solitary except during the mating season, from April to May, when they congregate in groups of 20 or more.
Key behaviors:
terricolous; saltatorial
; crepuscular
; motile
; sedentary
; solitary
.
Food Habits
Alaskan hares mainly eat woody vegetation, including willow leaves, shoots, bark, and roots. They also feed on grasses, berries, and flowers when they are available. Evenings are the most common time to feed.
Plant Foods:
leaves; roots and tubers; wood, bark, or stems; fruit; flowers.
Predation
Alaskan hares are not aggressive animals, they defend themselves mostly through hiding, aided by protective coloration. Still, they have been reported to defend themselves from attacking owls with their strong front legs. Raptors, weasels, wolverines, foxes, and polar bears are all potential predators of Alaskan hares.
Anti-predator adaptations::
cryptic
.
Economic Importance for Humans: Negative
As herbivores, Alaskan hares could cause damage to gardens, but this does not seem to be much of a problem among Arctic people.
Economic Importance for Humans: Positive
Although Alaskan hares are seldom used as a food source for humans, the meat is said to be quite tasty and Arctic people will eat them when necessary. They are more commonly trapped for fur, used to make lining for shoes and robes. They are also a popular sport hunting species.
Ways that people benefit from these animals:
food
; body parts are source of valuable material.
Conservation Status
IUCN Red List: [link]:
Lower Risk - Least Concern.
US Federal List: [link]:
No special status.
CITES: [link]:
No special status.
Lepus othus is described in "Mammal Species of the World" as rare and decreasing in range and numbers. However, none of the major conservation organizations list them among endangered or threatened species.
Other Comments
Lepus othus is quite similar to L. arcticus and L. timidus. Molecular data suggest these three are conspecific, while morphological data separate them. All are found in different geographic regions.
