  1. World Biomes

  2. What is a Biome? • A Biome is a term used to describe a major type of ecosystem that can found in various regions of the world • An ecosystem is the interaction of plant life, animal life, and the physical environment in which they live

  3. Why Study Biomes? Goal Understand the characteristics and spatial distribution of the different eco-systems. Central Questions Where is the Biome located? What characteristics define the Biome?

  4. Tundra

  5. Tundra • Characterized by Long snowy winters, & short marshy summers • Almost wholly located between 55 ̊N and 70 ̊N • Not suitable for large plants • Growing period • Permafrost Summer Highs: 12 ̊C Winter Lows: -70 ̊C Annual Precipitation: 18 -25cm

  6. Tundra

  7. Taiga

  8. Taiga • Characterized by large area of coniferous forests • Mainly located in sub-arctic regions of northern hemisphere • Supports many predators and migratory birds Summer Highs: 21 ̊C Winter Lows: -54 ̊C Annual Precipitation: 40-200cm

  9. Taiga

  10. Grasslands

  11. Grasslands • Located in mid-latitudes in the interior of continents • Sporadic rainfall and wildfires not suitable for large plants . • Full four seasons • Can support large herbivores Summer Highs: 38 ̊C + Winter Lows: -40 ̊C Annual Precipitation: 50-88cm

  12. Grasslands

  13. Deciduous Forest

  14. Deciduous Forest • Located on edge of Coniferous forests (Taiga) in East Asia, Europe, and East North America • Characterized by broadleaf forests • Precipitation evenly spread over 12 months • 4 Definitive Seasons • Wide variety of Flora and Fauna Avg Summer Highs: 30 ̊C Avg Winter Lows: -30 ̊C Annual Precipitation: 75-150cm

  15. Deciduous Forest

  16. Chaparral

  17. Chaparral • Located on Costal regions on SW corner of California, the Mediterranean , Australia, Chile, South Africa • Hot and Dry • Shrubs grow and can support grazing animals and scavengers Summer Highs: 40 ̊C + Winter Lows: 10 ̊C Annual Precipitation: 35-125cm

  18. Chaparral

  19. Desert

  20. Desert • Located mid-continental around tropics and Antarctica • Characterized as an area that gets less than 25cm of precipitation a year • Minimal plants and animals • Extreme High Temp: 36 ̊C • Extreme Low Temp: -18 ̊C

  21. Desert

  22. Savanna

  23. Savanna • Located in Southern Hemisphere • Similar to grasslands but able to support more trees • 6-8month rainy season followed by droughts and wildfires • Support large herbivores Constant Temps between 25 ̊C and 38 ̊C Annual Precipitation: 50-127cm

  24. Savanna

  25. Rainforest

  26. Rainforest • Located near equator in South America, Africa, and SE Asia • Near Constant Temps between 20 ̊C and 38 ̊C • Avg more than 250cm of rain a year • Support the most diverse life on earth (50% of all earth’s organisms) • Lungs of the world (produce 40% of oxygen) • Cover 6% of world

  27. Rainforest

  28. Alpine

  29. Alpine • Alpine refers to Mountainous regions with an altitude of 3000 meters or more • Located in western North America, western South America, Central and Northern Europe, and Central Asia • Due to weather the climate is unpredictable Summer highs reach to about 15 ̊C Winter will drop below 0 ̊C and normally last oct-may Some mountains peaks are permanently covered with snow
