The Alaskan hare (Lepus othus), also known as the tundra hare, is a species of mammal in the family Leporidae. [2] They do not dig burrows and are found in the open tundra of western Alaska and the Alaska Peninsula in the United States. They are solitary for most of the year except during mating season, when they produce a single litter of up to eight young. Predators include birds of prey and polar bears, as well as humans (typically for food).

Description

The Alaskan hare is one of the largest species of hares. [3] The Alaskan hare is sometimes referred to as the tundra hare. [4] They are one of two species of hares native to the state of Alaska in the United States, the other being the more common snowshoe hare. [4] Both male and female adults of Lepus othus normally measure between 50–70 centimetres (20–28 in) in length, with the tail measuring up to an additional 8 centimetres (3.1 in). Their hind feet are 20 centimetres (7.9 in) long, which is thought to allow them to move easily in snowy conditions. It has been reported that they also use their feet for defense against predators. This species weighs from 2.9 to 7.2 kg (6.4 to 15.9 lb), averaging 4.8 kg (11 lb), and it is thus one of the largest lagomorphs, alongside the similarly sized brown hare, Arctic hare and desert hare. [5] The Alaskan hare's ears are fairly short compared to most. [3] They have evolved shorter ears than most hares in order to conserve heat throughout the winter months. Hare's ears play an important role in thermoregulation, and with the Alaskan hare's ears being small, it prevents heat loss in cold climates. In the summer, Alaskan hares have a brown fur coat with white under parts. In the winter, they have a white fur coat with black-tipped ears. [3] They also shed their gray-brown summer topcoat, becoming all white during the winter. [5]

The Alaskan hare is mostly solitary, and usually only congregate in groups during mating season in April and May. [5] They will normally have one litter per year of between four and eight leverets, with the young born during June and July. The leverets are active shortly after birth, and are born with full coats and open eyes. [5] [3] Hares can also carry Tularemia which is a bacterial disease that can be transmitted to pets and humans. It can cause infectious wounds, swollen lymph nodes, and fever or symptoms that feel as if you have the flu. [6]

Taxonomy

The closest relatives of the Alaskan hare are the Arctic hare, Lepus arcticus, of northern Canada and Greenland, and the mountain hare, Lepus timidus, of northern Eurasia, [2] from which the Alaskan hare is geographically isolated. [1]

Habitat and diet

They do not live in burrows, but instead nest in open sites. They are most commonly found in upland tundra or in rocky or brushy areas which provide camouflage and protection from predators. [5] Their range includes western and southwestern Alaska, including the Alaska Peninsula. [1] [4] They are herbivores, eating a variety of foliage and fruits, with foraging taking place primarily at dawn and dusk. [5] Alaskan hares also feed on green plants in the summer, and bark and twigs in the winter. [3] Predators include foxes, polar bears, wolverines, weasels, and birds of prey. [5] They are taken opportunistically by humans for food or for their fur. [7] Their fur can be and is used to line shoes and robes in Alaska. [3]

<span class="mw-page-title-main">Hare</span> Genus of mammals in the family Leporidae

Hares and jackrabbits are mammals belonging to the genus Lepus. They are herbivores, and live solitarily or in pairs. They nest in slight depressions called forms, and their young are able to fend for themselves shortly after birth. The genus includes the largest lagomorphs. Most are fast runners with long, powerful hind legs, and large ears to dissipate body heat. Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a "leveret". A group of hares is called a "husk", a "down" or a "drove".

<span class="mw-page-title-main">Lagomorpha</span> Order of mammals

The lagomorphs are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae and the Ochotonidae (pikas). The name of the order is derived from the Ancient Greek lagos + morphē. There are 110 recent species of lagomorph of which 109 are extant, including 34 species of pika, 42 species of rabbit, and 33 species of hare.

Leporidae is the family of rabbits and hares, containing over 70 species of extant mammals in all. The Latin word Leporidae means "those that resemble lepus" (hare). Together with the pikas, the Leporidae constitute the mammalian order Lagomorpha. Leporidae differ from pikas in that they have short, furry tails and elongated ears and hind legs.

<span class="mw-page-title-main">Snowshoe hare</span> Species of mammal

The snowshoe hare, also called the varying hare or snowshoe rabbit, is a species of hare found in North America. It has the name "snowshoe" because of the large size of its hind feet. The animal's feet prevent it from sinking into the snow when it hops and walks. Its feet also have fur on the soles to protect it from freezing temperatures.

<span class="mw-page-title-main">Arctic hare</span> Species of mammal

The Arctic hare is a species of hare highly adapted to living in the Arctic tundra and other icy biomes. The Arctic hare survives with shortened ears and limbs, a small nose, fat that makes up close to 20% of its body, and a thick coat of fur. It usually digs holes in the ground or under the snow to keep warm and to sleep. Arctic hares look like rabbits but have shorter ears, are taller when standing, and, unlike rabbits, can thrive in extreme cold. They can travel together with many other hares, sometimes huddling with dozens or more, but are usually found alone, sometimes taking more than one partner. The Arctic hare can run up to 60 kilometres per hour (40 mph).

The wildlife of Alaska is both diverse and abundant. The Alaskan Peninsula provides an important habitat for fish, mammals, reptiles, and birds. At the top of the food chain are the bears. Alaska contains about 70% of the total North American brown bear population and the majority of the grizzly bears. as well as black bears and Kodiak bears. In winter, polar bears can be found in the Kuskokwim Delta, St. Matthew Island, and at the southernmost portion of St. Lawrence Island. Other major mammals include moose and caribou, bison, wolves and wolverines, foxes, otters and beavers. Fish species are extensive, including: salmon, graylings, char, rainbow and lake trout, northern pike, halibut, pollock, and burbot. The bird population consists of hundreds of species, including: bald eagles, owls, falcons, ravens, ducks, geese, swans, and the passerines. Sea lions, seals, sea otters, and migratory whales are often found close to shore and in offshore waters. The Alaskan waters are home to two species of turtles, the leatherback sea turtle and the green sea turtle. Alaska has two species of frogs, the Columbia spotted frog and wood frog, plus two introduced species, the Pacific tree frog and the red-legged frog. The only species of toad in Alaska is the western toad. There are over 3,000 recorded species of marine macroinvertebrates inhabiting the marine waters, the most common being the various species of shrimp, crab, lobster, and sponge.

<span class="mw-page-title-main">Alaska marmot</span> Species of rodent

The Alaska marmot, also known as the Brooks Range marmot or the Brower's marmot, is a species of rodent in the family Sciuridae. Once considered to be the same species as the hoary marmot, it is now known to be unique. Alaska marmots are found in the scree slopes of the Brooks Range, Alaska. Specifically, they prefer to dwell on rocky, mountainous terrain, generally near lakes. They eat vegetation found on mountainsides, such as grasses, seeds, and lichen. Their relatively thick bodies are covered in dense, grey fur. They live in large colonies that consist of multiple families. During the winter, they hibernate for long periods of time in burrows. While not well researched, they are not believed to be particularly threatened, by human activity or otherwise. The Alaskan government has designated February 2 as "Marmot Day," a holiday intended to recognize the prevalence of marmots in the state, similar to the more widely celebrated American holiday of Groundhog Day.
