The Tundra Biome
Transcript of The Tundra Biome
Factors: Abiotic Factors: Temperature: Weather and Precipitation: There's less than 25 cm (9.84 in) of rain each year. This biome is so cold that only very few plant and animal species can live there! Plant
Adaptations: Animal Adaptations Reasons to Visit: The tundra has a very short summer! Geographical
Distribution: The tundra is in the Northern Hemisphere. It covers most or all of North Pole, Northern Alaska, Canada, and Siberia. Tundra is about 20% of all earth! History What to Wear It was formed only 10,000 years ago! Many people say that it is at the top of the world. The word tundra came from the Finnish word, tunturia. Tunturia means a barren land The tundra is the youngest biome! Threats: There is a very high risk of climate change depending on the releases of methane and/or other gases. Endangered Species: Polar Bear Musk Ox Peregrine Falcon Peary Caribou Arctic Fox Bison Burrowing Owl Woodland Caribou White Pelican Swift Fox Grizzly Bear Kangaroo Rat Some Seasons: Average yearly temperature is -18 F (-8 C) 0 It's never warmer than 60 F (16 C) 0 0 0 The highest winter temperature is 20 F The highest summer temperature is 54-60 F 0 0 Winds are usually about 30-60 MPH! Only about 6-10 inches of precipitation (mostly snow) falls each year! Global Importance HEAD:
Tight, warm wool or cotton cap under hood. FACE:
Ski goggles and face cover (opt.) BODY:
Warm and waterproof ski pants and down parka over thick shirt and sweatshirt FEET:
Fur lined, waterproof boots with thick woolen socks Climate change!!! Temperature Rainfall Mineral Composition Season Altitude Cloud Coverage Sunlight Wind Permafrost Rocks Snow Ice Soil Summer (growing season) is only 6-10 weeks. Plants CAN grow and reproduce in that short amount of time! During the winter, it's dark almost all day and the sun barely rises Most tundra animals hibernate to survive the long, cold winter! There are nine months in the tundra where the temperature is never over 32 F 0 Oil and gas development can also cause global warming in the tundra which causes parts of it to melt. Ozone usage in the north and South Poles. Strong Ultraviolet rays can destroy the tundra. Air pollution causes smog clouds that contaminate lichen-food for many animals! Developing buildings and roads. Invasive species push away other plants and animals. Oil spills- Kill wildlife and damage ecosystems. Airborne Pollutants hurt the ecosystem without doing any good. Melting permafrost causes global warming which could seriously change the landscape and species. Anchorage, Alaska Has many historical landmarks and beautiful sights Amazing scenery and many species of wildlife. Wilderness adventures and attractions! #1 Place for Retirement #11 Best U.S. Places to Live and Play Many fun and interesting outdoors activities You're able to hike on a 1/2 mile deep glacier that is overall bigger than Rhode Island! Ice fishing, water rafting, hunting, sea kayaking, and even scuba diving! Has Alaskan heritage events You can view the Northern Lights! By Abby Uy and Zuriel Reyes We need glaciers, if they melt, artctic species will die out! So many plant and animal species live there! As well as the rainforest, it could also be called the earth's lungs because the tundra is also reponsible for converting most of the world's carbon dioxide into oxygen! Mutualism: Parasitism: Commensalism: Its permafrost has been very important in determining climate for hundreds of past years Examples of Black Flies Deer Flies Mosquitoes Tiny Biting Midges Lichens 1.

These tundra plants amazingly have the ability to grow and carry out photosynthesis under snow. Flowering plants can produce almost twice as fast as normal plants during the tundra's short summer. These plants' small leaf structure helps them keep the moisture they need that has already been stored. The caribou eats shrubs and other plants and then spreads it around for other species to eat through its waste. Fungal hyphae (part of lichen) surrounds algal cells, protecting and providing for it. The algal cells provide food and oxygen for the hyphae Migration and hibernation help all animals survive ARCTIC FOX:
This fox has short ears, a short round body, and a thick coat which help it stay warm since almost no skin is being exposed to the cold air. BROWN BEAR:
The brown bear eats everything it can in the summer, then hibernates during the whole winter without having to eat. MUSK OX:
This animal has two layers of fur, one short and one long, the short traps cold air and warms it, the warm air then warms the body. The long layer protects it from water and snow. Most parasitism in the tundra takes place between bugs, and larger mammals. Ticks take in nutrients by living in a caribou soon the caribou dies and the ticks get their food. However, most animals who are preyed upon can survive for many years while hosting parasites! Tapeworms (in caribou) and plastic worms (in wolves) both invade those animals' intestines and take their nutrients for themselves. The arctic fox follows the baren ground caribou, the arctic fox hunts the caribou's prey, after it has taken its rightful share, then left. The arctic fox also eats the lichens that the barren ground caribou uncovers while walking. Remora sharks have an adhesive disc on their heads that they attach to larger animals (usually whales) who are sloppy eaters and eat the food that floats away from the larger animal's mouth. Many other animals follow larger animals to scavenge remains of their prey, but the other example is the most common. We hope you enjoyed our prezi on the tundra biome! Bibliography:
