Alpine/Tundra Biome

Tundra. Tundras are among Earth's coldest, harshest biomes.


Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy and rainfall is scant. Tundra lands are snow-covered for much of the year, until summer brings a burst of wildflowers. Mountain goats, sheep, marmots, and birds live in mountain, or alpine, tundra and feed on the low-lying plants and insects. Hardy flora like cushion plants survive on these mountain plains by growing in rock depressions where it is warmer and they are sheltered from the wind.

The Arctic tundra, where the average temperature is 10 to 20 degrees Fahrenheit (-12 to -6 degrees Celsius), supports a variety of animal species, including Arctic foxes, polar bears, gray wolves, caribou, snow geese and musk-oxen. The few plants and animals that live in the harsh conditions of the tundra are essentially clinging to life. The Arctic tundra is changing dramatically due to global warming. KDE Santa Barbara.

Perhaps mountains or skiing? Well, you are right. Alpine biomes are found in mountain regions worldwide, including the Andes, Alps, and Rocky Mountains. The alpine biome usually lies between an altitude of about 10,000 feet (3,000 meters), and the place where the snow line of a mountain begins. WEATHER: In the summer average temperatures range from 40 to 60°F (4.5 to 15.5°C). PLANTS: The alpine biome is a tough place for plants to live. ANIMALS: Can you imagine living in a cold, windy place without much shelter? One interesting alpine animal is the chinchilla. PEOPLE AND THE ALPINE BIOME: You’ve probably heard of mount Everest and the Sherpas who help people climb it. Blue Planet Biomes: Alpine GF Awesome: Subalpine Ecosystems Back to Biomes Index. Alpine Biome. Alpine Biome at Animal Corner. Terrestrial Biome - Alpine During the summertime, temperatures in Alpine biomes reach around 40 to 60 degrees fahrenheit, however, come winter, temperatures are well below freezing and as the altitude increases, it can get much colder.

Alpine temperatures are dynamic and can change from warm to cold in one day. Winter seasons last from October to May and summer from June to September. The average rainfall on an Alpine biome is around 12 inches per year. The Latin word for 'Alpine' is 'Alps' meaning 'high mountain', this is where the word comes from. The Alpine Biome. The Alpine Biome Alpine biomes by their nature do not fit into a simple climatic scheme.

The Alpine Biome

In general, as one ascends a mountain, temperature drops by about 10 C for every 1000 meters in altitude gained (a suspiciously round number!). This means that if you start at sea level at 30 C and go up 1,000 meters the temperature will be 20 C; at the top of a 3,000 meter mountain the temperature will be 0 C. This the only thing you can say about the climate in alpine regions is that it is colder than one would expect at sea level at the same latitude.

Rainfall also varies considerably; as the rising air cools it loses the ability to retain moisture and clouds form, with the result of increasing precipitation on the side of a mountain exposed to winds. In these web pages the alpine "biome" will be considered to be the upper altitudes of mountains, where cooler climates give rise to communities which resemble (but do not duplicate) the taiga, tundra and ice biomes.

It was formed 10,000 years ago. Located at latitudes 55° to 70° North, the tundra is a vast and treeless land which covers about 20% of the Earth's surface, circumnavigating the North pole. It is usually very cold, and the land is pretty stark. Almost all tundras are located in the Northern Hemisphere.
