Transcript of Alpine

The alpine ecosystem
General informations
The Alpine Ecosystem starting at elevations from 3 400 meters
Strong, frequent winds and cold temperatures limit what plants can grow there
Most alpine plants are perennials
Some plants take two or more years to form flower buds, which survive the winter below the surface and then open and produce fruit with seeds in the few weeks of summer.
The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by the low air pressure
This ecosystem also includes animals such as mountain goats, which have hooves and fur adapted to living among the alpine cliffsides.
The treeline
is the zone where conditions become too harsh to support growth as large as trees. When viewing a mountain from the side, this line is visible as the place where forests stop and snow, ice and rock begin

The end
Cold environments, including polar and alpine regions, are colonized by a wide diversity of microorganisms able to thrive at low temperatures
Microorganisms
Flora
Alpine Bluegrass -legally protected
Small sparsely tufted grass of the Upper Peninsula; leaves are narrow ; inflorescence pyramidal, twice as tall as wide; lemmas are 3-nerved, have long, fine hairs between the margin and the keel, and lack a tuft of cobwebby hairs at the base.
Alpine Timothy
Spike Trisetum
It is native to North America, Eurasia, and South America. The grass occurs in a variety of Arctic and alpine habitat types, as well as many types of mountainous habitat in regions farther south. It is a perennial grass forming clumps of erect stems ranging in height from just a few centimeters to over one meter. The narrow leaves are mostly located around the bases of the densely clumped stems. The inflorescence is a narrow spike a few centimeters long or up to 30 to 50 centimeters in maximum length. The spikes are green to purple or brownish and shiny.
Tufted hair grass
It can be found on all types of grassland, although it prefers poorly drained soil. A distinguishing feature is the upper surface of the leaf blade which feels rough and can cut in one direction, but is smooth in the opposite direction. The upper side of the leaves are deeply grooved, and are dark green.
It can grow to 1.5 Meters tall, and has a long, narrow, pointed ligule.
Spike Wood
Rush-the Spiked Wood-rush grows commonly all over Iceland. Typically the inflorescences droop downwards as they mature. This is a very characteristic feature of this wood-rush species.
Grasses and Grass-like Plants:
Others:
Skyline Blue Grass,
Spreading Wheatgrass,
Kobresia,
Pyrennian Sedge
Forbs
Alpine Avens
Alpine Avens is often found in huge colonies, especially near tree line and on tundra. Its finely cut shiny leaves, maroon buds and very bright shiny yellow flowers make it a handsome and noticeable plant. Its leaves are often four-to-eight inches long below tree-line but are barely an inch or two long on Alpine Tundra.
Alpine Bistort
is common all over the high Arctic
-grows in many different plant communities, very often in abundance.
As with many other alpine plants, Alpine Bistort is slow growing, with an individual leaf or inflorescence taking 3-4 years to reach maturity from the time it is formed.
Arctic Gentian
is a late summer bloomer that can be abundant over large areas of alpine meadows. The flower is several inches tall, almost as tall as the entire plant. Flowers are creamy white to green white, with very strong streaks of purple on the outside and dots of purple on the inside. The plant is very easily overlooked.

Shrubs/Trees

Fauna
What's up ?!
Branchinecta paludosa
is a species of fairy shrimp with a Holarctic distribution
Salix Herbacea
Arolla Pine
Mountain pine
European larch
Animals
Wall Lizard
They have darker colored body to absorb heat better( beacause they live in cold areas)
Wallcreeper
is a small passerine bird found throughout the high mountains of Eurasia. It is the only member of the genus Tichodroma.
Golden Eagle
The Golden Eagle (Aquila chrysaetos) is one of the best-known birds of prey in the Northern Hemisphere. It is the most widely distributed species of eagle
The chamois, (Rupicapra rupicapra), is a goat-antelope species native to mountains in Europe. They are well adapted to climbing steep terrain where they seek from predators. They are proprietary.
Chamois
Alpine marmot
The Alpine Marmot (Marmota marmota) is a species of marmot found in mountainous areas of central and southern Europe. They are excellent diggers, able to penetrate soil that even a pickaxe would have difficulty with, and spend up to nine months per year in hibernation
European snow vole
Silver-washed Fritillary
Pale Clouded Yellow
is a small butterfly of the Family Pieridae

BY:
is the largest of the true foxes and the most geographically spread member of the Carnivora, being distributed across the entire Northern Hemisphere
Because of its widespread distribution and large population, the red fox is one of the most important furbearing animals harvested for the fur trade
RED FOX
is a mammal of the cat family. Is about twice as large as the domestic cat. The bobcat is crepuscular. The bobcat is able to survive for long periods without food
BOBCAT
Others: european pine marten, pika, pocket gopher, elk, long-tailed weasel, ground squirrel, mountain lion, mule deer...
It is a perennial bunchgrass forming loose clumps 20 to 60 centimeters tall. The inflorescence is a cylindrical to oval mass of spikelets up to 6 centimeters long and 1.2 wide.
