1 Biome: Tundra By: Mariah Hanson, Hannah Sanville and Veronica Yi Blue 2, Gray 2a, Wise, 09/16/13

2 Region Of The World Continues across North America, Europe and Asia Cover 1/5 of the world’s surface Largest and northernmost Biome

3 Abiotic Factors Temperature range: C to 12 0 C Permafrost 60 day growing season Average yearly precipitation: <25cm Soil

4 Abiotic Factors: Winter Climate Winter temperatures: -30 F in Artic Tundra's (North Pole) Coldest winters: Siberia, average winter temperatures: -40 F Has reached -93 F before. Mildest winters: Costal regions, average temperatures: 30 F Winter storms develop in the Aleutian Low and Icelandic Low

5 Abiotic Factors: Summer Climate Mild summers. Average temperatures: 45F Warmest summers occur in inland regions of Siberia, Alaska and Canada July temperatures there : 60 F Temperatures have been recorded in the 90’s F in those regions though Artic has rain and fog in summertime Short growing season because during the summer the Tundra doesn’t get a lot of rain

6 Abiotic Factors: Permafrost Permanent frozen layer of soil Surface above permafrost remains frozen all but 8 weeks of the year Prevents trees from growing

7 Abiotic Factors: Soil Slightly acidic Low nutrients due to cold temperatures Moist Thin topsoil over the permafrost

8 Biotic Factors: Animals Mammals Caribou Musk Oxen Artic Foxes Lemmings Snowshoe Hare Birds: Snowy Owls Ducks Geese Cranes Waterfowl Predatory Birds Musk Oxen Canadian Goose

9 Biotic Factors: Closer Look At The Artic Fox Mammal Diet: omnivore Average life span: 3 to 6 years Important adaptations to survive in chilly climate. Hardy animal, so it can survive in the tundra's frigid temperatures Lives in burrows

10 Biotic Factor: Closer Look At The Snowy Owl Carnivore Average life span: 9.5 years Patient hunter Breeds in Artic tundra Preferred meal is lemmings Diurnal: They hunt and are active during day and night.

11 Biotic Factors: Endangered Animals Artic Fox Polar Bear Northern Leopard Frog Bull Trout Whooping Crane Peregrine Falcon Northern Leopard Frog Whooping Crane

12 Endangered Animals: Closer Look at The Polar Bear Mammal Carnivore Average life span: 25 to 30 years Live in very cold climates Very strong swimmers May 2008 Polar bears were determined endangered

13 Biotic Factors: Plants/Fungi Plants Grasses Sedges Mosses Dwarf woody plants Fungi Lichens Moss

14 Biotic Factor: Closer Look At Lichens Reproduce asexually Fungus Unique due to not being a single organism Actually a combination of two organisms Most composed of fungal filaments
