Arctic hares feed primarily on woody plants, with arctic willow constituting 95% of their diet year-round. [15] Arctic hares predominantly consume saxifrage, crowberry, and dwarf willow, but can also eat a variety of other foods, including lichens and mosses, blooms, other species' leaves, twigs, and roots, mountain sorrel and macroalgae (seaweed).
Edible lichens are lichens that have a cultural history of use as a food. Although almost all lichen are edible (with some notable poisonous exceptions like the wolf lichen , powdered sunshine lichen , and the ground lichen [ 1 ] ), not all have a cultural history of usage as an edible lichen.
Brodoa oroarctica, commonly known as the Arctic sausage lichen, mountain sausage lichen, or rockgrub, is a species of rock-dwelling, foliose lichen in the family Parmeliaceae. [2] First described in 1974 by the Norwegian botanist Hildur Krog , it is characterised by its dark grey, irregularly spreading thallus with narrow cylindrical lobes that ...
The Arctic consists of desert and tundra vegetations. The desert vegetation consists of algae, lichens, and mosses. Lichens are the most dominant plants. The ground is bare with a patchy cover of lichens and mosses. [24] Flowering plants are also seen but not as common. It only contains 60 species of flowering plants.
There is a population of Arctic hares, brought to the islands by the lighthouse keepers, and crofters from Bernera graze sheep on the most fertile islands. [6] Minke and pilot whales, as well as Risso's and other species of dolphin are commonly observed in the vicinity. The islands became a Site of Special Scientific Interest in December 1983. [41]
Common names for lichens may contain the word moss (e.g., "reindeer moss", "Iceland moss"), and lichens may superficially look like and grow with mosses, but they are not closely related to mosses or any plant. [6]: 3 Lichens do not have roots that absorb water and nutrients as plants do, [15]: 2 but like plants, they produce their own ...
European hare (above) compared with a mountain hare Stuffed mountain hare, showing the winter pelage The mountain hare is a large species, though it is slightly smaller than the European hare . It grows to a length of 45–65 cm (18–26 in), with a tail of 4–8 cm ( 1 + 1 ⁄ 2 –3 in), and a mass of 2–5.3 kg ( 4 + 1 ⁄ 2 – 11 + 3 ⁄ 4 ...
Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.
