  1. Mountain and Alpine Tundra Rob Gregory Kelsey Burgess Mountain and Alpine Tundra By: Rob G and Kelsey B

  2. Map of Mountain/Alpine Tundra Biomes

  3. What is the Mountain and Alpine Tundra Biome? Mountains make up 20% of the earth They are places where dramatic changes in altitude, climate, soil and vegetation take place over a short distance Alpine tundra is the area above the coniferous tree life but under the snow caps of the mountains (Wikipedia)

  4. Average Temperature and Precip The Mountain/alpine biome is one of the coldest biomes in the world Temperature Range: -18 °C to 10 °C (-2 °F to 50°F) Average Annual Precipitation: 23 cm (9 in.) (Miller) (Alpine)

  5. Limiting Factors Controlling Climate Cold Temperature Lack of Sunlight High Winds Long Winters, Short Summers (Alpine)

  6. Flora (plants) • Alpine Phacelia • Bear Grass • Bristlecone Pine • Moss Campion • Polylepis Forest • Pygmy Bitterroot • Wild Potato • Grasses • Mosses • Dwarf woody shrubs (Alpine)

  7. Why these plants? • Adapted to: • -lack of sunlight and water • -freezing temperatures • -constant high winds • Most of the annual growth occurs in the 6-8 weeks of summer when there is the most sunlight • For a few weeks, the land blazes with color (wildflowers) (Alpine)

  8. Special Adaptations • Grow close to the ground to retain water and survive the winter cold • Some have leathery evergreen leaves coated by waxes that reduce heat loss • Others survive underground (roots, stems, bulbs, tubers) (Alpine)

  9. Fauna (animals) • Alpaca • Andean Condor • Chinchilla • Llama • Mountain Goat • Snow Leopard • Vicuña • Yak • Elk • Sheep • Golden Eagles • Marmots • Ground Squirrels (Alpine)

  10. Why these animals/special adaptations • They have thick coats of fur (Alpaca, Chinchilla, Snow leopard, Vicuña, Yak etc.) • Some have feathers to keep warm (condor) • Some animals have more red blood cells to adapt to the poor oxygen in higher altitudes (Llama) • Hooves adapted to slopes + help flexibility (Goat) • Fur blends in + nasal cavities help breathe (snow leopard) • Yak’s digestive track helps keep them warm (Alpine)
